The present patent/application is a continuation-in-part of the following patents/applications, each of which is incorporated by reference in full:
The present disclosure generally relates to telecommunication site installation systems and methods. More particularly, the present disclosure relates to battery handling systems and methods for telecommunication sites, such as cell sites.
Due to the geographic coverage nature of wireless service, there are hundreds of thousands of cell towers in the United States. With over 200,000 cell sites in the U.S., geographically distributed everywhere, installation and maintenance at cell sites can be expensive, time-consuming, and complex. For example, cell sites include a shelter or cabinet located proximate to the cell tower. For network availability, the shelter or cabinet includes a battery backup for power redundancy when a primary power source is unavailable, such as commercial power. For example, depending on configuration, the battery backup may include 4, 8, 16, 48, etc. batteries which each can weigh several hundred pounds. The installation/removal process such batteries is labor intensive and slow. It would be advantageous to provide a battery installation improvement apparatus and method in cell site shelters and the like to address the labor intensity and speed. Also, it would be advantageous to provide methods for installers to deal with the severe weight of the batteries during installation.
Currently, operators are dealing with high battery theft rates. Former technicians, employees, and subcontractors with known site access information makes removal of batteries an easy target as in many cases no forced entry is required, in addition to third parties who simply break in. Batteries are either delivered directly to or are picked up by smelters and recyclers in exchange for currency based on lead content and weight—and thus can return a high dollar amount.
Additionally, with hundreds of thousands of batteries installed at existing cell sites—and given an average of 5 years of life expectancy—there is a continuous need to monitor and replace batteries. With ever increasing Environmental, Health & Safety (EH&S) regulations and requirements put on wireless carriers, there is a growing need to efficiently and properly remove, dispose, and recycle used batteries. Proper handling, packaging, storage, and transportation of batteries in the recycling process is a critical component of battery replacement services. A clear chain of custody is required from the original removal of batteries at cell sites through the final recycling certificate showing completion of proper disposal.
Also, there is a need to inspect, audit, verify, etc. maintenance and installation work performed at cell sites. Further, there is a need to verify the proper configuration, installation, etc. over time. With thousands or more cell sites, such work is difficult, costly, and time-consuming. There is a need for efficient cell site audit and inspection systems and methods, specifically to verify battery and equipment connection integrity.
In an exemplary embodiment, a method of installing batteries in a telecommunications site includes obtaining a battery in a module with a plurality of cells in the module at a staging location; de-celling the battery to remove the plurality of cells from the module; handling the plurality of cells individually at the staging location; transporting the plurality of cells individually to the telecommunications site; and reassembling the battery by placing the plurality of cells back in the module and installing the module at the telecommunications site. The battery can include a 2V battery and the telecommunications site comprises a cell site.
The de-celling can include sliding the plurality of cells out of the module substantially parallel to the ground. The de-celling can include applying a spray lubricant to the plurality of cells prior to removal from the module. The de-celling can include applying a spray lubricant to the plurality of cells prior to removal from the module, and sliding the plurality of cells out of the module substantially parallel to the ground. The de-celling can include attaching a non-conductive bracket to the cells, attaching a strap to the bracket, and sliding the cells out using the bracket. The de-celling can include applying one of a spray lubricant, powder, gel, and petroleum to the plurality of cells prior to removal from the module, attaching a non-conductive bracket to the cells, attaching a strap to the bracket, and sliding the cells out using the bracket. The handling can include placing individual cells on a pallet with protective insulator layers and transporting the pallet to the site. The handling can include placing individual cells on a pallet with protective insulator layers, strapping the cells together and the cells to the pallet, shrink wrapping the pallet, and transporting the pallet to the site. The reassembling can include applying a spray lubricant to the plurality of cells prior to reinsertion in the module. The reassembled module can be positioned in a rack using a battery installation apparatus.
The battery installation apparatus can include a frame comprising four posts, wherein the frame is dimensioned to maneuver in a shelter or cabinet; a lower shelf fixed to the frame; an upper shelf moveable on the frame, wherein each of the lower shelf and the upper shelf are dimensioned to support the batteries; and omnidirectional wheels disposed to each of the four posts. The frame can be dimensioned based on a size of the battery system and a size of the shelter or cabinet. The battery installation apparatus can further include a pulley system coupled to the four posts to vertically raise and lower a shelf of the shelves. The pulley system can include a handle which is rotated to move the upper shelf and which holds the upper shelf when the handle is stationary.
The present disclosure is illustrated and described herein with reference to the various drawings, in which like reference numbers are used to denote like system components/method steps, as appropriate, and in which:
In various exemplary embodiments, the present disclosure relates to battery handling systems and methods for telecommunication sites, such as cell sites. Specifically, the systems and methods provide handling of hazardous or Environmental, Health, and Safety (EH&S) condition batteries. The EH&S condition batteries can be damaged, cracked, swollen, or leaking and are typically called out for immediate removal from a site.
Also, in various exemplary embodiments, the present disclosure relates to de-celling batteries for installation in telecommunication sites, such as cell sites. As described herein, de-celling includes separating individual battery cells from a manufacturer for transport to and installation at an associated site. The individual cells of a battery are easier to handle and install. The de-celling of batteries can be utilized with the battery recycling systems and methods, the security screws, and the battery installation improvement apparatus and method also described herein.
Also, in various exemplary embodiments, the present disclosure relates to cell site audit and inspection systems and methods related to battery and equipment connections. Specifically, paint or the like is utilized in a line across a connection once the connection is properly torqued. The torque marks can be verified as part of close-out audits following any installation or maintenance work and then verified over time including remotely via virtual site surveys.
Also, in various exemplary embodiments, the present disclosure relates to battery recycling systems and methods such as with respect to cell sites. Specifically, the battery recycling systems and methods provide an efficient, safe, and verifiable approach to recycling batteries. The systems and methods track used (spent) batteries from the deinstallation process at a cell site through final recycling evidenced by a recycling certificate. The systems and methods include various tracking techniques such as implemented through mobile devices and cloud systems.
Also, in various exemplary embodiments, the present disclosure relates to a battery installation with security screws for theft deterrence in cell site shelters and the like. Specifically, the battery installation utilizes security screws in various configurations for anchoring and securing batteries on site, such as at a cell site. Further, a method of installation is also described. The security screws require a specialized bit or tool for locking and tightening. Batteries can be anchored to terminal plates with the security screws. Further, the batteries can be locked together with one another forming a single unit, increasing the weight and bulk of the single unit presenting significant challenges to remove the batteries. Even further, brackets can be used with the security screws to attach the batteries to a shelf, cabinet, etc.
Also, in various exemplary embodiments, the present disclosure relates to a battery installation improvement apparatus and method in cell site shelters and the like. The apparatus includes an adjustable rack dimensioned to fit into small telecom cabinets or shelters and used to remove old batteries and install new batteries quickly (i.e., multiple batteries at a time) and efficiently (i.e., less labor required). The adjustable rack includes omnidirectional wheels and can be maneuvered/positioned in the shelter adjacent to a battery system. The adjustable rack includes adjustable shelves which can be positioned adjacent to old batteries for removal thereof, the apparatus can be wheeled out of the shelter to remove the old batteries, new batteries can be placed on the adjustable shelves, which can be positioned at appropriate heights based on the removal, and the apparatus can be maneuvered/positioned back to the battery system where the new batteries are provided. Advantageously, the apparatus can be used by a single installer, more than doubling the efficiency in removing/installing batteries. Also, in an exemplary embodiment, the apparatus can be used in conjunction with the security screws and installation approach.

In other embodiments, the battery system 80 can omit the housing 84 where the batteries 82 are directly connected to one another and supported, for example, by shelves or simply placed on the ground and on top of one another. The batteries 82 can include a handle 90 or the like for an installer to handle physically.
§ 4.0 Battery Installation Apparatus
Referring to
The apparatus 100 can include a fixed bottom shelf 130 connected or disposed to the posts 106, 108, 110, 112. The apparatus 100 can also include a moveable shelf 132. The moveable shelf 132 is adjustable based on four pulleys 140, 142, 144, 146. The pulley 140 includes a handle 148 that is adapted to rotate to move a rope or other winch type mechanism which is connected to the other pulleys 142, 144, 146 as well. Movement of the handle 148 causes the moveable shelf 132 to move vertically evenly in either direction (based on the rotation direction of the handle 148). When the handle 148 is stationary, the moveable shelf 132 remains fixed in place.
The shelves 130, 132 are configured to support the batteries 82. Specifically, the apparatus 100 is dimensioned to support the N batteries 82, sort of like a mobile battery system 80. The moveable shelf 132 is vertically adjusted to match the height of the second row of the batteries 82 in the battery system 80.
In an exemplary embodiment, a battery installation apparatus for installing and removing batteries in a shelter or cabinet includes a frame comprising four posts, wherein the frame is dimensioned to maneuver in the shelter or cabinet; a lower shelf fixed to the frame; an upper shelf moveable on the frame, wherein each of the lower shelf and the upper shelf are dimensioned to support the batteries; and omnidirectional wheels disposed to each of the four posts.
To install the batteries, a plurality of batteries are placed on the lower shelf and the upper shelf; the frame is moved into the shelter or cabinet to a location proximate and adjacent to a battery system in the shelter or cabinet; the upper shelf is adjusted based on the battery system; and each of the plurality of batteries is moved to the battery system. To remove the batteries, the frame is moved into the shelter or cabinet to a location proximate and adjacent to a battery system in the shelter or cabinet; old batteries from the battery system are placed on the upper shelf and the lower shelf; the frame is moved out of the shelter or cabinet; and the old batteries are removed.
The frame can be dimensioned based on a size of the battery system and a size of the shelter or cabinet. The battery installation apparatus can further include a pulley system coupled to the four posts to raise and lower a shelf of the shelves vertically. The pulley system can include a handle which is rotated to move the upper shelf and which holds the upper shelf when the handle is stationary. The battery installation apparatus can include a rectangular shape. The plurality of batteries can include N batteries, N=4, 8, 16, 24, or 48. The battery installation apparatus can be operated by a single installer. The shelter or cabinet can be at a cell site.

§ 6.0 Security Screws for Battery Installation
Referring to
A spanner screw has two small holes drilled in its head and is designed to be installed and removed with a special spanner screw-driver. The security screw 300 is an example of a spanner screw. A tamper-resistant Allen-head screw is designed to be removed only with a specially modified Allen wrench having a small hole drilled in its end to accept the protruding pin in the head of the screw. Also, the security screws can have unique, proprietary designs making them more tamper resistant than off-the-shelf variants such as the spanner screw. Again, the systems and methods described herein contemplate the use of any type of security screw.
Referring to
In the systems and methods, the terminals 402, 404 are physically connected to the terminal plates 406, 408 using the security screws 300 (or any variant of security, tamper proof, or tamper resistant screw). The security screws 300 are used in lieu of conventional screws. On-site installation personnel is equipped with an associated unique tool to fasten and tighten the security screws 300 physically connecting the terminals 402, 404 with the terminal plates 406, 408. Note, the terminal plates 406, 408 can also be connected at an opposite end via the security screws 300. The security screws 300 have minimal increased cost from conventional screws and add little to no additional installation time. At the same time, the security screws 300 advantageously lock the battery 400 in place, minimizing the risk of theft. That is, once installed, the battery 400 is physically locked and cannot be undone without the unique tool.
Also, paint can be applied to the security screw 300, the terminals 402, 404, and the terminal plates 406, 408 after the security screw 300 is tightened. The paint is for quality control, to show that the steps have been taken to appropriately tighten the security screw 300 (to the specified torque)—assumption is made that if someone takes the trouble to apply the paint, they have appropriately tightened the screw. And, if the paint is applied and dries in place on a tightened security screw 300 and then is found to be broken, the security screw 300 is no longer tight—an easy visual confirmation of appropriately tightened connections.

Referring to
The placing step 602 can include placing the one or more batteries on shelves of a battery installation apparatus; moving the battery installation apparatus into the shelter or cabinet to a location proximate and adjacent to a battery system in the shelter or cabinet; adjusting an upper shelf of the shelves on the battery installation apparatus based on the battery system; and moving each of the one or more batteries from the shelves to the battery system. The battery installation method 600 can further include moving the battery installation apparatus into the shelter or cabinet to the location; removing old batteries from the battery system and placing the old batteries on the shelves; moving the battery installation apparatus out of the shelter or cabinet; and removing the old batteries.
The battery installation apparatus can be dimensioned based on a size of the battery system and a size of the shelter or cabinet. The battery installation apparatus can include omnidirectional wheels for maneuverability. The battery installation apparatus can include a frame with posts supporting the shelves and with a pulley system to vertically raise and lower a shelf of the shelves. The battery installation apparatus can include a rectangular shape with a lower shelf fixed to a frame. The moving can be through a pulley system which rotates a handle to move the upper shelf and holds the upper shelf when the handle is stationary. The one or more batteries can include N batteries, N=4, 8, 16, 24, or 48. The battery installation method 600 can be performed by a single installer. The shelter or cabinet is at a cell site.
§ 7.0 Used Battery Handling and Recycling
Referring to
The battery recycling method 700 initiates on site with uniquely identifying and marking used batteries (step 702). Specifically, step 702 includes arriving on site such as at the cell site 10 and identifying the used batteries 82. The used batteries 82 can be uniquely identified or tagged as they are removed from the cell site 10. For example, the battery recycling method 700 can include the use of a mobile device 800 which is used to track the used batteries 82 electronically. The mobile device 800 can execute an application or browser to communicate/store data on a back-end server or in the cloud related to the uniquely identified and marked batteries 82. For example, a technician assisting in performing the battery recycling method 700 can note the quantity, make, model, etc. of the used batteries via the mobile device 800 and the mobile device 800 can provide this data to the back-end server or the cloud for tracking and compliance. For example, once the data is input in step 702, the technician can confirm prior to, concurrent with, or subsequent to the removal of the batteries 82 for transport from the cell site 10 to a warehouse/temporary staging facility.
Also, as part of the uniquely identifying and marking used batteries, a certificate of recycling can be generated stating that the company performing the battery recycling method 700 has taken ownership of the used batteries 82 along with language that confirms the battery recycling method 700 will be followed and performed to comply with applicable regulations (e.g., Environmental Protection Agency (EPA) guidelines, etc.). The certificate of recycling can also identify the recycling facility, etc. and the purpose of the certificate of recycling is to allow the cell site 10 operator assurances regarding proper procedures and transfer of liability. Again, the certificate of recycling can be electronic, through the back-end server or the cloud.
The used batteries 82 are packaged and removed from the cell site 10 (step 704). The used batteries 82 can be any size, e.g., 12V which is about 2-3 times the size of a typical car battery, or the like. For example, the removal of the used batteries 82 can utilize the battery installation apparatus 100 to efficiently remove the batteries 82 from the cell site 10. The used batteries 82 are packaged such as placed on pallets or the like and removed from the cell site 10 for staging, such as at the warehouse/temporary staging facility (step 706). The battery recycling method 700 contemplates the technician or multiple technicians visiting one or more cell sites 10 and performing steps 702, 704 at the cell site 10 and step 706 as a transportation step between the cell site 10 and the warehouse/temporary staging facility. For example, multiple cell sites 10 can be visited for removing batteries 82 before returning to the warehouse/temporary staging facility.
At the warehouse/temporary staging facility, after a certain number of used batteries 82 have been staged, the used batteries 82 are packaged for recycling in a safe manner (step 708). The safe manner includes various steps and packaging to ensure the used batteries 82 can be safely transported to the recycling facility. For example, the packaging must include insulation to protect battery leads from touching metal or the like during transport. The packaging can include a cardboard or wooden box with form fitting slots for each battery 82, and the box can sit on a pallet. Alternatively, the batteries 82 can be directly placed on a pallet such as with an empty sheet of cardboard (or wood or other suitable insulating material) placed on top of the empty pallet. The sheet of cardboard can include markings with lines and with identifiers. The technicians can place each battery 82 on an empty space based on the markings. Also, the associated identifier can be noted, such as through the mobile device 800. For example, battery X which was uniquely identified at cell site A was placed on pallet N in space 1. That is, during the lifecycle of the battery recycling method 700, each time the battery 82 is moved or packaged, this can be noted via the mobile device 800.
Once a complete layer of batteries 82 is placed on the pallet 750 or in the box, another sheet of cardboard (or wood or other suitable insulating material) is placed on top of the batteries 82. Further, each of the batteries 82 can have a tape or similar adhesive with insulating properties placed on the terminals to prevent contact or leaking during transport. The layering of the batteries 82 can be repeated until a certain height is achieved on the pallet 750, e.g., three rows. The top layer of batteries 82 can have another sheet of cardboard (or wood or other suitable insulating material) placed on top, and this can be referred to as a top sheet of cardboard, i.e., the top sheet 754. Similar to the insulation sheet 752, the top sheet 754 can include an empty sheet of cardboard (or wood or other suitable insulating material). Also, the top sheet 754 can have sides that extend beyond the outer edge of the top row of batteries 82.
Once the top sheet 754 is placed on a full pallet 750, the pallet 750 can be banded through the bottom of the pallet 750 and around the batteries 82 such as using a poly type material strapping to secure the load as a single unit that does not shift during transport. It is important to avoid any metal in strapping down the batteries 82 to avoid any contact with the used batteries 82. The pallet 750 can also be wrapped in shrink wrap or the like covering the outer edges of the top row of batteries 82 down to and including around the outside corner of the pallet 750.
The pallet 750 can be labeled with appropriate information including warnings such as non-combustible and other relevant information such as the site ID and quantity, make, a model of batteries and estimated weight for each pallet 750. The pallet 750 can also be labeled with number tracking, e.g., pallet 1 of 15, 2 of 15, etc.
With the label and the completely packed pallet 750, the battery recycling method 700 can include a verification step where a photo is taken of the pallet 750 including the label, and this photo can be uploaded to the back-end server or the cloud and correlated with each battery 82 being tracked. This photo can serve as a confirmation that the batteries 82 were packed and loaded on the pallet 750 and are ready to ship.
With packed pallets 750, the packed, used batteries 82 are sent to a recycling facility (step 710). For example, a Bill of Lading (BOL) can be prepared for shipment document the total number of pallets and estimated weight for shipment.
Importantly, the used batteries 82 are tracked at each step in the battery recycling method 700, such as using the mobile device 800 and the back-end server/cloud. Various reports can be generated including an inventory label sheet—an overall document created that shows batteries by pallet #, battery quantity, make & model and site origin. Also, this information can be accessible by the cell site owner 10 on demand, e.g., a process map which shows where the used batteries 82 are in the battery recycling method 700.
Once a final recycling certificate is received, the overall document is attached to verify the tracking of batteries at the individual level from removal to recycle (step 714). For example, the recycling certificate can be used for liability issues—battery X was found in a landfill, and there is a fine or the like—the cell site operator now has a document showing the liability resides with the operator of the battery recycling method 700.
The battery recycling method 700 can be adapted to different service providers, and the interface between the back-end server/cloud can be programmed to interface with back office systems for various service providers to automate various data exchanges. Also, the back-end server/cloud can include scheduling applications such as to schedule pick ups, new battery installations, etc.

The software in memory 810 can include one or more software programs, each of which includes an ordered listing of executable instructions for implementing logical functions. In the example of
§ 9.0 Cell Site Audit/Inspection/Site Survey
In general, a cell site audit (or site inspection, site survey, etc.) is performed to gather information and identify a state of the cell site 10. This is used to check the installation, maintenance, and/or operation of the cell site 10. Various aspects of the cell site audit can include, without limitation:
Of note, the cell site audit includes gathering information at and inside the shelter 50, on the cell tower 12, and at the cell site components 14. The cell site audit (site inspection, site survey, etc.) is used for various purposes including to verify proper installation, proper maintenance, and proper operation over time.
§ 9.1 Torque Mark to Verify Power and Equipment Connections
It can be difficult to remotely verify connections such as battery connections, coax connections, etc. The systems and methods described herein provide a mechanism to visually and even remotely verify connection veracity merely by visual inspection. Referring to
While
Also, the torque mark 850 contemplates any material or the like which can be physically attached to both ends of the connection and which would break or visually show signs of decay based on the connection losing torque. For example, the torque mark 850 can be paint, a marker, cellophane, tape, wax or wax-like compound, silicon, etc. Also, for ease of application, the material for the torque mark 850 can have an adhesive that is removed allowing for quick application. Alternatively, the material for the torque mark 850 can be dispensed through a dispensing apparatus.
The torque mark 850 can be applied across a top of the bolt in a line extending onto the surface of the object the bolt is connected to. If the bolt loosens, the torque mark 850 will break and/or fall off. Thus, simple visual inspection can confirm that the connections are still at the torque they were originally tightened to. Advantageously, the torque mark 850 as paint does not fade as a pen or marker would. Further, the torque mark 850 is easily verified remotely through virtual site surveys as described herein.
§ 10.0 3D Modeling Systems and Methods for Cell Site Audits
Three-dimensional (3D) modeling and photo data capture can be used for remote, virtual site surveys, audits, inspections, etc. of the cell site 10, specifically the shelter 50. The photo data capture can be through any means, including portable cameras, fixed cameras, heads up displays (HUD), head mounted cameras, and the like. The systems and methods described herein contemplate the data capture through any available technique. Referring to
The terminals 910, equipment 912, and the power distribution 914 can be realized as rack or frame mounted hardware with cabling 916 and with associated modules 918. The modules 918 can be pluggable modules which are selectively inserted in the hardware and each can include unique identifiers 920 such as barcodes, Quick Response (QR) codes, RF Identification (RFID), physical labeling, color coding, or the like. Each module 918 can be unique with a serial number, part number, and/or functional identifier. The modules 918 are configured as needed to provide the associated functionality of the cell site.
The systems and methods include photo data capture in the interior 900 for 3D modeling and for virtual site surveys. The photo data capture can be performed by a fixed, rotatable camera 930 located in the interior 900. The camera 930 can be communicatively coupled to a Data Communication Network (DCN), such as through the wireless backhaul equipment 912 or the like. The camera 930 can be remotely controlled, such as by an engineer performing a site survey from his or her office. Other techniques of photo data capture can include an on-site technician taking photos with a camera and uploading them to a cloud service or the like. Again, the systems and methods contemplate any type of data capture.
Again, with a plurality of photos, e.g., hundreds, it is possible to utilize photogrammetry to create a 3D model of the interior 900 (as well as a 3D model of the exterior as described above). The 3D model is created using physical cues in the photos to identify objects of interest, such as the modules 918, the unique identifiers 920, or the like.
§ 11.0 Virtual Site Survey

§ 14.0 De-Celling Battery Systems and Methods
Referring to
Referring to
The battery de-celling process 1100 includes de-celling cells in a battery rack module and attaching a non-conductive bracket to the de-celled cells (step 1102). Step 1102 is performed prior to installing the batteries and can be performed at a staging location, such as a warehouse, at a manufacturer, etc. The de-celling includes removing individual cells from a rack module. For example, de-celling the battery in
To aid in the removal of the cells from the modules, a spray lubricant can be used. The description herein refers to a spray lubricant, but those skilled in the art will recognize other products could also be used, such as a powder, a gel, petroleum, etc. Note, the use of the spray lubricant is based on a type/manufacturer of the batteries. That is, some brands of batteries require the spray lubricant whereas others do not. To del-cell the cells, the non-conductive bracket can be attached to one of the cell terminals (positive only or negative only), a strap can be attached to the bracket, and the cell is slid out by pulling on the strap. For example, the rack module can be positioned such that the sliding is parallel to the ground to aid in removal (not against gravity and optionally the spray lubricant assists in the sliding). Note, other embodiments are also contemplated including sliding the cells out at any angle, upside down, perpendicular, etc.
The individual cells are handled separately and transported to a site (step 1104). The site can include the cell site 10, such as the interior 52 of the shelter 50. Step 1104 includes the transportation from the staging location to the installation site. The individual cells and module are closer to ˜200 lbs. which is easier to handle. The cells and rack modules can then be handled separately, transported to the site, and re-assembled at the site.
The transport/handling of the de-celled batteries can include placement of a protective insulator layer on a pallet, and the de-celled batteries are placed on top of the protective insulator layer on the pallet. For example, the protective insulator layer can be cardboard or the like. This is similar to the battery recycling systems and methods. Also, another cardboard layer can be placed on top of the de-celled batteries to cover the battery terminals for safe transport. The cells can be banded/strapped together and banded/strapped to the pallet. Finally, the pallet can be shrink wrapped, loaded onto a truck or the like, and transported to the site.
Once at the site, the individual de-celled cells are reassembled and installed (step 1106). Specifically, the rack module is reassembled at the site, i.e., the opposite of the de-celling, including bolting empty modules together to form battery rack, optionally using the spray lubricant to ease re-insertion of cells into the rack module, etc. The re-assembled module can then be inserted into position in the shelter 50, such as using the battery installation apparatus 100 or the like.
§ 15.0 Handling Hazardous or Environmental, Health, and Safety (EH&S) Condition Batteries
The identifying is to determine batteries that are hazardous or have an EH&S condition. Once these are identified, these batteries must be handled separately from any other normal condition batteries being removed from the telecommunication site. Each individual battery must be wrapped in plastic to prevent additional contamination and each individual battery must then be placed in cardboard or rigid plastic container. The container should be labeled with a battery ID (site location), make, model, etc. and/or the container should be labeled with the hazardous condition. Once back at temporary staging facility (storage facility), the container should be stored separate from normal condition batteries, e.g., never taken off pallet and monitored for potential leaking. The container should not be packaged on any pallet containing other batteries for transport. A shipping coordinator should identify the EH&S batteries and pallets separately on BOL to alert the smelter (recycling facility) for receiving and proper handling once it is shipped to final recycling destination.
The individual wrapping can utilize a plastic wrap and the container comprises a cardboard or rigid plastic container. Each of the one or more batteries can be labeled with identification which provides a location of the telecommunications site, a make, and a model. The identification can be scannable via a mobile device which communicates with a cloud system for performing the tracking and the process 1200 can further include providing alerts based on events associated with the tracking. Each of the one or more batteries can be labeled with identification indicative of the hazardous condition. The container can be both electrically ground and sealed for containing any leakage from the one or more batteries.
The process 1200 can further include de-celling one or more cells of the one or more batteries prior to the individually wrapping. The process 1200 can further include handling the containers by placing the containers on a pallet with protective insulator layers and transporting the pallet to the storage facility and to the recycling facility. The handling can include placing individual cells on a pallet with protective insulator layers, strapping the cells together and the cells to the pallet, shrink wrapping the pallet, and transporting the pallet to the site.
The removing can utilize a battery installation apparatus including a frame including four posts, wherein the frame is dimensioned to maneuver in a shelter or cabinet; a lower shelf fixed to the frame; an upper shelf moveable on the frame, wherein each of the lower shelf and the upper shelf are dimensioned to support the batteries; and omnidirectional wheels disposed to each of the four posts. The frame can be dimensioned based on a size of the battery system and a size of the shelter or cabinet. The battery installation apparatus can further include a pulley system coupled to the four posts to vertically raise and lower a shelf of the shelves. The pulley system can include a handle which is rotated to move the upper shelf and which holds the upper shelf when the handle is stationary. The battery installation apparatus can include a rectangular shape.
The process 1200 can further include providing a recycling certificate to an operator of the telecommunications site evidencing successful recycling of the one or more batteries. Based on the tracking, a list of battery quantity, make, model, and weight from each corresponding telecommunication site can be added to the recycling certificate indicating clear chain of custody from the telecommunication site through final disposal at the recycling center.
§ 16.0 Power Cable Lug Connections
A process for power cable lug connections includes measuring the length of lug against the cable. The cable outer casing is cut back such that the exposed copper/inner cable matches the length of the lug. An appropriately sized piece of heat shrink tubing is cut and slid onto the cable above the cut/exposed portion. No-oxidation material is placed on the exposed cable section/inner cable, where the outer casing has been removed. The lug is seated onto the exposed cable section/inner cable such that the end of the lug fits snugly against the cable's outer casing. There should be no “shiner,” no exposed gap between end of the lug and the cable's outer casing that would expose the copper/inner cable. The heat shrink tube is slid down to be centered over the area where the lug and the cable's outer casing meets—extending onto the lug and over the cable's outer casing. The shrink wrap is heated to specified temperature to shrink fit onto the cable's outer casing and lug. The heat shrink ensures a non-conductive barrier is in place if the lug/cable connection loosens.
Although the present disclosure has been illustrated and described herein with reference to preferred embodiments and specific examples thereof, it will be readily apparent to those of ordinary skill in the art that other embodiments and examples may perform similar functions and/or achieve like results. All such equivalent embodiments and examples are within the spirit and scope of the present disclosure, are contemplated thereby, and are intended to be covered by the following claims.
