If electrically powered accessory 240 indicates that electric energy is needed to power, e.g., electrically powered accessory RESS 241, electrically powered accessory 240, controller 215 may control ePDU 210 to distribute AC and/or DC power received from electrical supply equipment 220 to electrically powered accessory 240.

Controller 215 may be further configured, programmed, or otherwise designed to communicate with controller 233 of vehicle 230. In at least one embodiment, vehicle 230 may include sensors that provide data regarding, e.g., temperature, pressure, voltage, current, battery status, and/or battery power level sensor, etc., of at least on-board charger 231 and rechargeable energy storage system (RESS) 232. Controller 233 may communicate the status, e.g., status of the sensors and/or charge status, to controller 215. In at least one other embodiment, sensors associated with controller 215 may be provided to detect and facilitate reporting of, e.g., temperature, pressure, voltage, current, battery status, and/or battery charging level sensor, etc. Controller 215 may communicate, e.g., status of the sensors and/or charge status, to controller 233.

Controller 215 may be configured, programmed, or otherwise designed to communicate the information received from electrical supply equipment 220 to vehicle 230. Vehicle 230 may initiate/request power delivery from electrical supply equipment 220, via controller 215 and the CP line.

If vehicle 230 indicates that electric energy is needed to charge the vehicle 230, controller 215 may control ePDU 210 to distribute AC and/or DC power received from electrical supply equipment 220 to vehicle 230 to provide power to the on-board charger 231 and/or to charge the RESS 232.

As set forth above, controller 215 may be further configured, programmed, or otherwise designed to communicate with a controller of electrically powered accessory 240, e.g., climate-control unit. In at least one embodiment, accessory 240 may include sensors, e.g., temperature, pressure, voltage, current, battery status, and/or battery charging level of, at least, RESS 241.

It will be appreciated that power demand/request from electrically powered accessory 240, e.g., for powering the transport climate control system to keep the cargo, e.g., produce, frozen foods, pharmaceuticals, etc., safe and/or fresh may have higher priority than power demand/request from vehicle 230, e.g., for delivering power to a battery associated with vehicle 230. As such, controller 215 may control ePDU 210 to distribute AC and/or DC power received from electrical supply equipment 220 to electrically powered accessory 240 first, and then to vehicle 230 if the higher priority power demand from the electrically powered accessory 240 is satisfied. That is, electrical power source priorities may include prioritizing load integrity attributable to accessory 240 over delivering power to vehicle 230.

FIG. 3 illustrates a block diagram representing components of the controller 215 corresponding to a power management system, in accordance with at least one embodiment described herein. As depicted, controller 215 may include, at least, power supply detector 305, power meter 310, power observer 313, power source manager 315, power delivery unit 320, and communications manager 325. As set forth above, the description of each successive drawing may reference features from one or more of the previous drawings to provide clearer context and a more substantive explanation of the current example embodiment. Still, the example embodiments described in the detailed description, drawings, and claims are not intended to be limiting. Further, although illustrated as discrete boxes or components, any one or more of boxes 305, 310, 313, 315, 320, and 325 may be divided into additional boxes or components, combined into fewer boxes or components, or eliminated altogether while being contemplated within the scope of the disclosed subject matter. It will be understood by those skilled in the art that each function and/or operation of the boxes or components may be implemented, individually and/or collectively, by a wide range of hardware, software, firmware, or any combination thereof.

Power supply detector 305 may refer to a component that is configured, programmed, or otherwise designed to detect an incoming electrical connection from, at least electrical supply equipment 220, via electrical power line 207. Controller 215 may communicate with electrical supply equipment 220 and a utility power source (not shown) in order to prioritize and control power flow to electrical components associated with vehicle 230, including but not limited to a vehicle battery, and to electrically powered accessories 240, including not but limited to a CCU, which may or may not have an energy storage device to receive delivered energy associated therewith.

Power supply detector 305 may detect incoming electrical connection from electrical supply equipment 220 upon power line 207 corresponding to electrical supply equipment 220 being electrically connected to ePDU 210.

Power meter 310 may refer to a component that is configured, programmed, or otherwise designed to assess electrical power needs for electrical components associated with the vehicle and electrical power needs for electrical components associated with the transport climate-control system.

Power meter 310 may read or otherwise determine power needs, i.e., power needed to reach full energy or at least sustainable energy for completion of a task, of electrical components associated with vehicle 230 including, but not limited to, rechargeable energy storage system 232, which may include a e.g., battery. As recited and described herein, vehicle 230 may communicate readings taken by and/or from sensors regarding, e.g., temperature, pressure, voltage, current, battery status, and/or battery energy level sensor, etc., to controller 215. Similarly, electrically powered accessory rechargeable energy storage system 241 may also have sensors disposed thereon to communicate readings associated with electrically powered accessory 240 regarding at least, e.g., temperature, pressure, voltage, current, battery status, and/or battery energy level of, at least, RESS 241, when the electrically powered accessory 240 is a CCU for a transport climate control system.

Thus, power meter 310 may read or otherwise determine the aforementioned power needs of the vehicle 230 based on data received from sensors corresponding to the electrical storage system associated with vehicle 230, as well as from sensors corresponding to the electrically powered accessory 240. In at least some embodiments, the sensors corresponding to electrically powered accessory are disposed on a corresponding electrical storage device.

Power observer 313 may refer to a component that is configured, programmed, or otherwise designed to calculate power currently available and forecast usage rates of power by vehicle 230 and/or a battery associated with vehicle 230, as well as calculate power currently available and forecast usage rates of power by accessory 240, e.g., climate control unit. Using such calculations, in part or in whole, power observer 313 may determine if power demands by vehicle 230 and/or accessory 240 are to be adjusted.

Power source manager 315 may refer to a component that is configured, programmed, or otherwise designed to determine power source priorities of vehicle 230 and electrically powered accessory 240 based on, at least, the assessed electrical power needs thereof, and allocate the incoming electrical power based at least in part on the power source priorities. By at least some embodiments, power source manager 315 may determine power source priorities associated with vehicle 230 and/or accessory 240 based on forecast usage by one or both, as calculated by power observer 313. Further, by the embodiments described and recited herein, the power source priorities may be alternatively determined based on power needs or forecast power usage of electrical components associated with either of vehicle 230 or accessory 240.

Power source manager 315 may prioritize delivering power to the electrical storage system associated with vehicle 230 and with electrically powered accessory 240, which may or may not have an electrical storage device associated therewith, based on transport load integrity over delivering power to, e.g., a battery of vehicle 230. That is, top priority for delivering power to the electrical storage system based on a determination of the power needs of electrically powered accessory 240, or a power demand/request therefrom, that the fate of the cargo is likely dependent upon the climate of the corresponding container when the electrically powered accessory 240 is a CCU. Alternatively, the power demand/request from electrically powered accessory 240 may be based on a forecast usage rate of power thereby. That is, when power source manager 315 determines or is informed that the cargo within a container corresponding to vehicle 230 is dependent upon a consistent climate and that maintaining such climate is dependent upon the delivery of power to accessory 240, power source manager 315 is to assign a higher priority to accessory 240, which may or may not include the delivery of power to an associated electrical storage device. By such embodiment, a CCU may correspond to electrically powered accessory 240, and provide climate control to at least one of the internal space of the vehicle, an internal space of a trailer, or an internal space of a shipping container. The structure and functionality of power source manager 315 is described in more detail in U.S. application Ser. No. 16/565,235, “AN INTERFACE SYSTEM FOR CONNECTING A VEHICLE AND A TRANSPORT CLIMATE CONTROL SYSTEM,”.

In at least one alternative embodiment or scenario for which transport load integrity is not a top priority, power source manager 315 may prioritize delivering power to vehicle 230 and/or the electrical components associated therewith based on, at least, an assessed time required for respective ones vehicle 230 and accessory 240, e.g., the transport climate-control system to be fully charged. That is, based on data received from sensors corresponding to both the electrical storage system associated with vehicle 230 and the electrical storage device associated with electrically powered accessory 240, power source manager 315 may allocate power delivery to either disproportionately based on a computation of time efficiency for delivering power to both the vehicle 230 and accessory 240. Considerations for this scenario may include, but not be limited to, a manual override of instructions to controller 215 indicating that transport load integrity is not a present risk, etc.

In at least one other alternative embodiment or scenario for which transport load integrity is not a top priority, power source manager 315 may prioritize delivering power to the electrical components associated with vehicle 230, thus allocating power to the electrical storage system associated with vehicle 230 at a disproportionately higher rate than that to electrically powered accessory 240 (e.g., a CCU). Considerations for this scenario may include, but not be limited to, a manual override of instructions to controller 215 indicating that transport load integrity is not a present risk, a manual override of instructions to controller 215 to ensure electrical operation of vehicle 230, etc.

In accordance with at least some embodiments, power source manager 315 may be configured, programmed, or otherwise designed to receive authorization before delivering power to the electrical storage system associated with vehicle 230 or the electrical storage device associated with the transport climate-control system. That is, a user may interface with at least controller 215 of ePDU 210 via an application that is installed on or running on user interface device 290 or via a web-based application. Thus, authorization for the electrical storage system or the electrical storage device to receive power may be required, via the application, prior to power is delivered.

Power delivery unit 320 may refer to a component that is configured, programmed, or otherwise designed to distribute AC and/or DC power received from electrical supply equipment 220 to electrically powered accessory 240, via electrical power line 227, and to rechargeable energy storage system 232 associated with vehicle 230, via electrical power line 217. Power delivery unit 320 may distribute power in accordance with instructions received, or data detected, from power source manager 315.

Communications manager 325 may refer to a component that is configured, programmed, or otherwise designed to facilitate data communications with electrical supply equipment 220, controller 233 of vehicle 230, and electrical accessory 240.

In accordance with at least one embodiment, power source manager 315 may be configured, programmed, or otherwise designed to place a higher priority for delivering power to the electrically powered accessory (e.g., maintaining transport load integrity when the electrically powered accessory 240 is a climate control unit) over, at least, delivering power to an electrical storage system for vehicle 230. Such prioritization may have various motivations. For example, when the electrically powered accessory 240 is a climate control unit used in a transport climate control system, prioritization may be grounded in maintaining, e.g. freshness of produce, potency of pharmaceuticals, etc., by prioritizing sufficient power delivery to ensure climate control to at least one of the internal space of the vehicle, an internal space of a trailer, or an internal space of a shipping container.

In at least one alternative embodiment, block 415 may refer to power source manager 315 prioritizing delivering power to the electrical components associated with vehicle 230 based on, at least, an assessed time required to fully charge respective ones of the electrical components charged by the electrical storage system of vehicle 230 and of the electrical storage device of electrically powered accessory 240.

In at least one other alternative embodiment, block 415 may refer to power source manager 315 prioritizing delivering power to the electrical components associated with vehicle 230, thus delivering power to the electrical storage system associated with vehicle 230 at a disproportionately higher rate than that to the electrical storage device for the electrically powered accessory 240. Operations may proceed to block 420.

Block 420 (Authorize), in accordance with at least some embodiments, may refer to power source manager 315 receiving authorization to facilitate power delivery to the electrical storage system associated with vehicle 230 or facilitate power delivery to the electrical storage device associated with the electrically powered accessory 240, upon receiving user authorization via, e.g, a smartphone app or a web-based application on user interface device 290.
