The EV rescue system 100 can include a rescue vehicle 110 that can include a mobile platform 111 that can comprise, in some embodiments, a winch 112 and a ramp feature 113. The mobile platform 111 can operate as a ramp by mechanized tilting of the mobile platform 111 toward the ground in front of a disabled vehicle as shown by dashed lines in
In some embodiments, the entire platform can be manipulated away from the rear of a truck as a rescue vehicle 110 to place the mobile platform 111 in front of a disabled vehicle 105 that requires towing or transportation. In some embodiments, the mobile platform 111 of the rescue vehicle 110 can be deployed into an angled position in contact with the ground (or close to the ground) for retrieving the disabled EV 105 (the “rescued vehicle”) thereon by operation of a winch 112, which can be connected to a tow hook, or the like, located near the front of a disabled EV 105 as the disabled EV 105 is mechanically pulled onto the mobile platform 111 by the winch 112. Once the disabled EV 105 is in place on the mobile platform 111, it can be secured with straps or chains for transportation.
A charging unit 120 can be included in association with the electric vehicle rescue system 100 for connection to and charging of a battery associated with the disabled EV 105 by connection to a connection port 115 of the EV 105. The EV 105 can include one or more batteries as part of an ESS of the EV 105. That is, the EV 105 includes an ESS that can include the aforementioned battery (or batteries), which can be recharged by the charging unit 102. Charging of the EV 105 can occur either on location or during transport of the EV on the mobile platform 111. A customer (e.g., the user of the EV 105) may be charged separately for charging and transportation, depending on the elected service.
A systems analysis module 130 can also be included in association with the electric vehicle rescue system 100 for testing of the functionality of systems and components of the EV 105, either on site or during transport of the EV 105 on the mobile platform 111. The system analysis module can be connected to a test port (not shown) that may be provided in a compartment within the EV 105. Results of analysis can be provided to customers in printed form or electronically via a data network. The customer may also be charged separately for the analysis.
Results of the analysis by the system analysis module 130 can be provided as data to customers in, for example, a printed form or electronically (e.g., email, a text message, social media messaging, etc.) via a data network. For example, these results can be electronically sent to the customer (e.g., the driver or owner of the disabled EV 105) or another person or entity/service (e.g., a roadside assistance service) in an email, text message or another form of electronic notification (e.g., social media messaging). The customer may be charged separately for this analysis. Note that the term ‘customer’ as utilized herein can relate to the driver/owner of the disabled EV 105 and/or a user of a mobile ‘app’ associated with an entity such as, for example, the aforementioned roadside assistance service. In the case of this mobile app, the customer can request assistance from the roadside assistance service through the mobile app.
The mobile platform 111 can be provided with the rescue vehicle 110 in the form of a trailer pulled by another vehicle (e.g., pulled by a heavy duty truck) or integrated with another vehicle (e.g., the truck 110 as shown). That is, in an embodiment, the rescue vehicle 110 may be a truck or similar vehicle, and the mobile platform 111 can be located on a trailer pulled (e.g., flatbed trailer) pulled by the rescue vehicle 110. In an alternative embodiment, the rescue vehicle 110 and the mobile platform 111 may be incorporate into the same vehicle. For example, as shown in
In some embodiments, the electric vehicle rescue system 100 can include the ability to carry passengers from with the disabled EV 105 as the disabled EV 105 is being transported, charged, and/or analyzed by the rescue vehicle. For example, the mobile platform 111 can be integrated or installed onto the back of a heavy duty, four door truck 107 (e.g., crew cab) that can also function as a shuttle for transporting the paying passengers (i.e., the passenger and/or driver of the disabled EV 105).
It is also a feature of the disclosed embodiments that the rescue vehicle can include means for charging batteries associated with the rescue vehicle or the rescued vehicle. Such means for charging can include but is not limited to at least one PV panel associated with the mobile platform 111 to charge batteries when a vehicle is not being transported. A generator 140 can also be associated with one or more of the wheels 145 (or axles) of the rescue vehicle and can generate power as the rescue vehicle is moving on a road or highway while transporting a rescued electric vehicle. This power can be utilized for charging the rescued electric vehicle. The time that it takes to charge an EV can be dependent on the amount of amperage and power that can be provided by the charging system. There may be, for example, Level 1, Level 2, and DC charging stations available at stationary locations.
The DC charging stations, such as, for example, the 480 volt DC CHAdeMO fast charging stations, are the highest power systems available today, are a three-phase system, and can charge an EV as soon as, for example, 20-30 minutes; however, significant power must be generated to accomplish fast charge. On the mobile platform 111, a fast charge may also be accomplished if additional means for generating power are provided. For example, a bank of batteries may be available on or in association with the mobile platform 111 to transfer DC charging energy to the EV batteries of the ESS of the EV 105. Variations of solar panels, generators, and other batteries may provide enhanced charging capabilities for the rescue vehicle.
The charging unit 120 can thus implement a fast charge with respect to the disabled EV 105 located on the mobile platform 111. The term ‘fast charge’ as utilized herein relates to fast charging of electric batteries associated with electric vehicles. The charging unit 120 can be modified to deliver a fast charge such as disclosed in U.S. Patent Application Publication No. 20210268931entitled “System, Apparatus and Methods of Electricity Generation to End-Use for Fast Charging of Electric Vehicle,” which was published on Sep. 2, 2021, and is incorporated herein by reference in its entirety. some embodiments, the charging unit 120 may include an EV
Retrieval, transport, charging, and analysis are features that can be offered to disabled vehicles as part of a roadside assistance program. Referring to
The data network 1400 can couple devices so that communications may be exchanged, such as between a remote server (RS) 1300 and client devices or other types of devices, including between wireless devices coupled via a wired or a wireless network, for example. The data network 1400 can in some example embodiments include mass storage, such as network-attached storage (NAS), a storage area network (SAN), or other forms of computer or machine-readable media, for example. The data network 1400 may include the Internet, one or more local area networks (LANs), one or more wide area networks (WANs), wire-line type connections, wireless type connections, cellular communications networks, or any combination thereof. Likewise, sub-networks may employ differing architectures or may be compliant or compatible with differing protocols and may interoperate within a larger network. Various types of devices may, for example, be made available to provide an interoperable capability for differing architectures or protocols. As one illustrative example, a router may provide a link between otherwise separate and independent LANs.
The data network 1400 may communicate with client devices, network towers 250 and so on via a communications link or channel which may include, for example, analog telephone lines, such as a twisted wire pair, a coaxial cable, full or fractional digital lines including T1, T2, T3, or T4 type lines, Integrated Services Digital Networks (ISDNs), Digital Subscriber Lines (DSLs), wireless communications links including satellite links, cellular communications links, or other communication links or channels. Furthermore, a computing device or other related electronic devices may be remotely coupled to a network, such as via a telephone line or link, for example. Customers 220, for example, may use client devices such as the client device 22 shown in
The communications link or channel may include wireless communications means. That is, the data network 1400 can be configured as a wireless network that can couple client devices with the data network 1400 via wireless communications means. The data network 1400 may employ stand-alone ad-hoc networks, mesh networks, wireless LAN (WLAN) networks, cellular networks, or the like. The data network 1400 can be a wireless network that includes a system of terminals, gateways, routers, or the like coupled by wireless radio links, or the like, which may move freely, randomly, or organize themselves arbitrarily, such that network topology may change, at times even rapidly. A wireless network may further employ a plurality of network access technologies including Long Term Evolution (LTE), WLAN, Wireless Router (WR) mesh, or 2nd, 3rd, 4th generation (2G, 3G, 4G, 5G) cellular technology, or the like. Network access technologies can enable wide area coverage for client devices and so on with varying degrees of mobility, for example.
The data network 1400 can be configured as a wireless network that enables RF or wireless type communication via one or more network access technologies, such as Global System for Mobile communication (GSM), Universal Mobile Telecommunications System (UMTS), General Packet Radio Services (GPRS), Enhanced Data GSM Environment (EDGE), 3GPP Long Term Evolution (LTE), LTE Advanced, Wideband Code Division Multiple Access (WCDMA), Bluetooth, 802.11b/g/n, or the like. The wireless network 1400 may include virtually any type of wireless communication mechanism by which signals may be communicated between devices, such as a client device or a computing device, between or within a network, or the like.
Signal packets communicated via the data network 1400 may be compatible with or compliant with one or more protocols. The signaling formats or protocols employed may include, for example, TCP/IP, UDP, DECnet, NetBEUI, IPX, AppleTalk, or the like. Versions of the Internet Protocol (IP) may include IPv4 or IPv6.
The Internet refers to a decentralized global network of networks. The Internet includes local area networks (LANs), wide area networks (WANs), wireless networks, or long haul public networks that, for example, allow signal packets to be communicated between LANs. Signal packets may be communicated between nodes of a network, such as, for example, to one or more sites employing a local network address. A signal packet may, for example, be communicated over the Internet from a user site via an access node coupled to the Internet. Likewise, a signal packet may be forwarded via network nodes to a target site coupled to the network via a network access node, for example. A signal packet communicated via the internet may, for example, be routed via a path of gateways, servers, etc., that may route the signal packet in accordance with a target address and availability of a network path to the target address.
Mobile ‘apps’, such as UBER and LYFT are available on mobile devices to hire transportation from point A to point B for a customer. However, there is not a similar app that can match rescue vehicles with disabled vehicles in need of rescue. The term “app” as utilized herein refers to an application or software application such as a software program. An ‘app’ can refer to software or software programs used on a mobile computing device such as a smartphone, a tablet computing device, a wearable computing device, and so on. In other embodiments, an ‘app’ may refer to a “web app” or “online app” such as software that a user can access and use while online, via for example, a browser, instead of residing on a client device.
Thus, in some embodiments an “app” may be a software application that can be resident on and/or run on a mobile computing device, while and in other embodiments the mobile app may be accessed and used online via a client device such as a mobile computing device, a laptop computer, a computer server, a desktop computer and so on. An example of the client device is the client device 22 shown in
As shown next at block 320, the server can determine the requester's location and locate service providers near the requester. This determination of the requester's location may be based on geographical location (e.g., GPS signal) associated with the requester's mobile device. As depicted next at block 330, the requester can select a service provider to provide rescue services for the disabled EV 105. This selection can be made through, for example, the aforementioned mobile app.
As indicated next at block 340, the selected service provider can accept the request. Then, as described at block 350, the service provider can bill the requester (e.g., the user or customer) upon completion of services including one or more of EV charging, EV transportation, and EV analysis.
The client device 22 may be, for example, a desktop computer or a portable device, such as a cellular telephone, a smartphone, a display pager, a radio frequency (RF) device, an infrared (IR) device, a Personal Digital Assistant (PDA), a handheld computer, a tablet computer, a laptop computer, a wearable computer, or an integrated device combining various features, such as features of the foregoing devices, or the like. In a preferred example embodiment, however, it can be assumed that the client device 22 is a mobile device such as, for example, a smartphone, tablet computing device, a smartwatch, or other wearable computing devices.
The client device 22 may vary in terms of capabilities or features. The claimed subject matter is intended to cover a wide range of potential variations. For example, a cell phone is a client device that may include a numeric keypad or a display of limited functionality, such as a monochrome liquid crystal display (LCD) for rendering text and other media. In contrast, however, as another example, a web-enabled client device may include one or more physical or virtual keyboards, mass storage, one or more accelerometers, one or more gyroscopes, global positioning system (GPS) or other location identifying type capability, or a display with a high degree of functionality, such as a touch-sensitive color 2D or 3D display, for example. The client device 22 may be a mobile device such as, for example, an iPhone™, an iPad, an Android Phone, a laptop computer, and so on.
The client device 22 can include or can execute a variety of operating systems, such as operating system 241, including in some example embodiments, a personal computer operating system, such as a Windows®, iOS® or Linux®, or a mobile operating system, such as iOS®, Android®, or Windows Mobile®, or the like. Thus, in some example embodiments, the client device 22 may be a smartphone such as an iPhone® or an Android®-based smartphone or other types of smartphones. In another embodiment, the client device 22 may be a tablet-computing device such as an iPad, a Galaxy tablet, and so on. In still other embodiments, the client device 22 may be a wearable computing device such as a smartwatch, or simply a portable computing device such as a laptop computer.
The client device 22 may include or may execute a variety of possible applications, such as a client software application enabling communication with other devices, such as communicating one or more messages, such as via email, short message service (SMS), or multimedia message service (MMS), including via a network, such as an online social network, including, for example, Facebook®, LinkedIn®, Twitter®, Flickr®, Instagram®, TikTok®, and so on.
The client device 22, may also include or execute an application to communicate content, such as, for example, textual content, multimedia content, or the like. A client device may also include or execute an application to perform a variety of possible tasks, such as browsing, searching, playing various forms of content, including locally stored or streamed video, or games (e.g., fantasy sports leagues, etc.). The foregoing is provided to illustrate that claimed subject matter is intended to include a wide range of possible features or capabilities. Examples of such applications or “apps” (or modules) can include a messenger app 243, a browser app 245, and other client application(s) or module(s) such as an EVR (Electric Vehicle Rescue) app 247 that can facilitate interactivity and communications between the client device 22 and a remote server such as the remote server 1300 shown in
The client device 22 can include a CPU (Central Processing Unit) 222 and/or other processors (not shown) coupled electronically via a system bus 224 to memory 230, power supply 226, and a network interface 251. The memory 230 can be composed of RAM (Random Access Memory) 232 and ROM (Read Only Memory) 234. Other example components that may be included with client device 22 can include, for example, an audio interface 252, a display 254, a keypad 256, an illuminator 258, and an input/output interface 260. In some embodiments, a haptic interface 262 and a GPS (Global Positioning System) module or unit 264 along with a Bluetooth (BT) module 265 and an NFC (Near Field Communications) module 267 can also be electronically coupled via the system bus 224 to CPU 222, memory 230, power supply 226, and so on.
The BT (Bluetooth) module 265 can permit communication of client device 22 with other devices, including Bluetooth and/or BLE beacons and/or transponders as discussed herein. For example, the rescue vehicle 110 may be equipped with Bluetooth communications components and/or BLE beacons and/or transponders that may communicate with client device through Bluetooth, BLE communications and so on. The near field communication (NFC) module 267 can facilitate NFC communication with other devices including, e.g., an NFC beacon. With respect to the Bluetooth module 265, it may be implemented as a Bluetooth Low Energy (BLE) module and/or a Bluetooth 4.0 module that implements communications using one or more of BLE systems, standard Bluetooth systems, and/or iBeacon systems specifically. As understood herein, BLE may operate in the same spectrum range (e.g., the 2.400 GHz-2.4835 GHz band) as classic Bluetooth technology but may use a different set of channels. Instead of Bluetooth's seventy-nine 1-MHz channels, e.g., BLE can employ forty 2-MHz channels. BLE may send data within a channel using Gaussian frequency shift modulation with a one megabyte per second data rate and a maximum transmission power of ten milliwatts (10 mW).
RAM 232 can store an operating system 241, provide for data storage 244, and the storage of applications 242 such as, for example, browser 245 and messenger 243 applications. ROM 234 can include a BIOS (Basic Input/Output System) 240, which is a program that the CPU 222 utilizes to initiate the computing system associated with client device 22. BIOS 240 can also manage data flow between operating system 241 and components such as display 254, keypad 256, and so on.
Applications 242 can thus be stored in memory 230 and may be “loaded” (i.e., transferred from, for example, memory 230 or another memory location) for execution by the client device 22. Client device 22 can receive user commands and data through, for example, the input/output interface 260. The client device 22 in accordance with instructions from operating system 241 and/or application(s) 242 may then act upon such inputs. The interface 260, in some embodiments, can serve to display results, whereupon a user may supply additional inputs or terminate a session. The software application(s) 242 can include one or more modules such as modules 243, 245, 247, and so on, which can, for example, implement instructions or operations such as those described herein.
The client device 22 can communicate through, for example, a data communications network such as the data network 1400 and the aforementioned remote server 1300. In some example embodiments, the data network 1400 may be implemented as a wireless network, which may, for example, employ stand-alone ad-hoc networks, mesh networks, wireless LAN (WLAN) networks, cellular networks, or the like. Such a wireless network can include a system of terminals, gateways, routers, or the like coupled by wireless radio links, or the like, which may move freely, randomly or organize themselves arbitrarily, such that network topology may change, at times even rapidly. Such a wireless network may further employ a plurality of network access technologies, including Long Term Evolution (LTE), WLAN, Wireless Router (WR) mesh, or 2nd, 3rd, or 4th generation (2G, 3G, or 4G) cellular technology, or the like. Network access technologies may enable wide area coverage for devices, such as client devices with varying degrees of mobility, for example.
For example, a data network such as data network 1400 may enable RF or wireless type communication via one or more network access technologies, such as Global System for Mobile communication (GSM), Universal Mobile Telecommunications System (UMTS), General Packet Radio Services (GPRS), Enhanced Data GSM Environment (EDGE), 3GPP Long Term Evolution (LTE), LTE Advanced, Long-Term Evolution Time-Division Duplex (LTE-TDD), LTE-FDD, LTE Direct, 4G, Wideband Code Division Multiple Access (WCDMA), Bluetooth, 802.11b/g/n, or the like. The data network 1400 may include virtually any type of wireless communication mechanism by which signals may be communicated between devices, such as a client device or a computing device, between or within a network, or the like.
Signal packets communicated via the data network 1400, such as a network of participating digital communication networks may be compatible with or compliant with one or more protocols. The signaling formats or protocols employed may include, for example, TCP/IP, UDP, DECnet, NetBEUI, IPX, AppleTalk, or the like. Versions of the Internet Protocol (IP) may include IPv4 or IPv6.
Note that the Internet refers to a decentralized global network of networks. The Internet includes Local Area Networks (LANs), Wide Area Networks (WANs), wireless networks, or long haul public networks that, for example, allow signal packets to be communicated between LANs. Signal packets may be communicated between nodes of a network, such as, for example, to one or more sites employing a local network address. A signal packet may, for example, be communicated over the Internet from a user site via an access node coupled to the Internet. Likewise, a signal packet may be forwarded via network nodes to a target site coupled to the network via a network access node, for example. A signal packet communicated via the Internet may, for example, be routed via a path of gateways, servers, etc. that may route the signal packet in accordance with a target address and availability of a network path to the target address.

As illustrated in
As illustrated, the various components of data-processing system/apparatus 400 can communicate electronically through a system bus 350 or similar architecture. The system bus 350 may be, for example, a subsystem that transfers data between, for example, computer components within data-processing system/apparatus 400 or to and from other data-processing devices, components, computers, etc. The data-processing system/apparatus 400 may be implemented in some embodiments as, for example, a server in a client-server based network (e.g., the Internet) or in the context of a client and a server (i.e., where aspects are practiced on the client and the server).
In some example embodiments, data-processing system/apparatus 400 may be, for example, a standalone desktop computer, a laptop computer, a smartphone, a pad computing device and so on, wherein each such device is operably connected to and/or in communication with a client-server based network and/or other types of networks (e.g., cellular networks, Wi-Fi, etc.).
The following discussion is intended to provide a brief, general description of suitable computing environments in which the system and method may be implemented. Although not required, the disclosed embodiments will be described in the general context of computer-executable instructions, such as program modules, being executed by a single computer. In most instances, a “module” can constitute a software application, but can also be implemented as both software and hardware (i.e., a combination of software and hardware).
Generally, program modules include, but are not limited to, routines, subroutines, software applications, programs, objects, components, data structures, etc., that perform particular tasks or implement particular data types and instructions. Moreover, those skilled in the art will appreciate that the disclosed method and system may be practiced with other computer system configurations, such as, for example, hand-held devices, multi-processor systems, data networks, microprocessor-based or programmable consumer electronics, networked PCs, minicomputers, mainframe computers, servers, and the like.
The term module as utilized herein may refer to a collection of routines and data structures that perform a particular task or implements a particular data type. Modules may be composed of two parts: an interface, which lists the constants, data types, variable, and routines that can be accessed by other modules or routines, and an implementation, which is typically private (accessible only to that module), and which includes source code that actually implements the routines in the module. The term module as utilized herein may also simply refer to an application, such as a computer program designed to assist in the performance of a specific task, such as word processing, accounting, inventory management, etc. In other embodiments, a module may be a hardware component or a combination of hardware and software.
As utilized herein, the term “vehicle” can be defined as a conveyance that provides transport to humans, animals, machines, cargo, or other objects. An “occupant” is defined as a person, animal, or machine that is transported or transportable by a vehicle. In view of this definition, a person, animal, or machine may be considered an occupant when inside the vehicle or outside the vehicle. Thus, an occupant may be, for example, a vehicle driver or a vehicle passenger.
The term ‘vehicle’ as utilized herein can in some embodiments relate to an autonomous vehicle. That is, in some embodiments, the rescue vehicle 110 may be an autonomous vehicle and/or the disabled EV 105 may be an autonomous vehicle. The term ‘autonomous vehicle’ as utilized herein can relate to a vehicle (e.g., an electric vehicle, a motorized vehicle, etc.) that can navigate without a human driver. An autonomous vehicle can include a plurality of sensor systems, such as, but not limited to, a camera sensor system, a lidar sensor system, a radar sensor system, amongst others, wherein the autonomous vehicle can operate based upon sensor signals output by the sensor systems. Specifically, the sensor signals can be provided to an internal computing system in communication with the plurality of sensor systems, wherein a processor can execute instructions based upon the sensor signals to control a mechanical system (e.g., vehicle propulsion system, a braking system, a steering system) and/or an electrical system of the autonomous vehicle.
The term ‘vehicle’ as utilized herein can also relate to a so-called connected vehicle (which may or may not be an autonomous vehicle). The term “connected vehicle” can relate to a vehicle that can be equipped with Internet access, and usually also with a wireless local area network. This can allow the vehicle to share Internet access with other devices both inside as well as external to the vehicle. The connected vehicle can be outfitted with special technologies that tap into the Internet or a wireless LAN and provides additional benefits to the occupant. For safety-critical applications, a connected vehicle can be connected using Dedicated Short Range Communication (DSRC) radios, operating in the FCC-granted 5.9 GHz band with very low latency.
As noted above, a connected vehicle may or may not be an autonomous vehicle. An “autonomous vehicle” can be a vehicle configured to sense its environment and navigate itself with or without human interaction. An autonomous vehicle may operate in one or more modes, including a fully autonomous mode, a semi-autonomous (for example, adaptive cruise control) mode, or in a manual mode (e.g., the human operator/driver has control of the vehicle). A vehicle that is semi-autonomous may include a mode in which the vehicle may operate as a vehicle driven by a driver and in other situations the same vehicle may function as a completely autonomous vehicle.
In some example embodiments, the disabled EV (Electric Vehicle) 105 may be vehicle that is driven by a human operator (e.g., a vehicle driver) or may be a vehicle such as a connected vehicle and/or an autonomous vehicle. The rescue vehicle 110 of the EV rescue system 100 may similarly in some example embodiments be a vehicle such as a connected vehicle and/or an autonomous vehicle. A non-limiting example of an autonomous vehicle and related systems and methods, which may be adapted for use as, for example, the vehicle 105 and/or the vehicle 110 is disclosed in U.S. Patent Application Publication No. 20170320501, entitled “Systems and Methodologies for Controlling an Autonomous Vehicle,” which published on Nov. 9, 2017 and which is incorporated herein by reference in its entirety.
In some embodiments, when the electric vehicle 105 becomes disabled, a rescue signal can be transmitted via wireless communications 103 to the bidirectional wireless packet-based data network 1400 to the remote server 1300, which can be associated with and/or communicates with an electric vehicle rescue service 1302. The rescue signal may include, for example, GPS coordinates and/or other geolocation information of the electric vehicle 105.
The rescue vehicle 110, which in this scenario may also be an autonomous vehicle with a passenger or passengers, can be dispatched to the location of the disabled vehicle 105 for rescue/transportation, and analysis and charging of the disabled vehicle 105, as discussed previously. It can be assumed that the rescue vehicle 110 can be configured to automatically attach and tow the disabled vehicle 105 as discussed previously herein, or the rescue vehicle may be a semi-autonomous vehicle with a human occupant to assist in the

Continuation-in-Part process of towing and charging the disabled vehicle 105 as discussed previously herein.
[000107] The term “vehicle” as utilized herein can refer not only to automobiles such as cars and trucks, but can also refer to aircraft, such as airplanes, helicopters and other types of aircraft, such as mini aircraft, air taxis, personal airplanes and so-called “flying cars”. Such vehicles may be piloted by a human or may be semi-autonomous or completely autonomous vehicles. One example of an aircraft that can be adapted for use as a ‘vehicle’ is disclosed in non-limiting U.S. Patent Application Serial No. US20160023754 Al entitled “Vertical take- off aircraft” which was published on January 28, 2016 and is incorporated herein by reference in its entirety. Another non-limiting example of a personal aircraft that can be adapted for use as a ‘vehicle’ is disclosed in non-limiting U.S. Patent Application Serial No. US20130214086, which published on August 22, 2013 and is incorporated herein by reference in its entirety.
[000108] Yet another example of an aircraft that can be adapted for use as a ‘vehicle’ is the TriFan 600 aircraft manufactured by XTI Aircraft, which is an aircraft that uses three ducted fans. Other non-limiting example of various types of aircraft that can be adapted for use in accordance with various example embodiments are disclosed in the paper “Fast Forwarding to a Future of On-Demand Urban Air Transportation,” Uber Elevate, dated October 27, 2016, which is incorporated herein by reference in its entirety. An autonomous vehicle may also be an unmanned aerial vehicle or system (UAV/UAS), a drone, an unmanned ground vehicle, an unmanned water vehicle, or any other type of autonomous vehicle.
[000109] In some embodiments, the rescue vehicle 110 of the EV rescue system 100 may include an aircraft as discussed above that can fly to the location of the disabled EV 105 and may connect to the disabled EV 105 and lift the disabled EV 105 from the ground into the air and fly the disabled EV 105 to another location and charge the disabled EV 105 “in flight”. By the time the disabled EV 105 is transported by air to the other location, the batteries of the EV 105 may be partially charged or completely charged. In this scenario, the rescue vehicle 110 can be implemented as aircraft which may be configured with a mobile platform that can lift and transport the disabled EV 105 to another location. In some embodiments,

Continuation-in-Part the rescue vehicle 110 may be an aerial drone that can fly to the location of the disabled EV 105 to retrieve and transport the disabled EV 105 and charge it while in flight.
The electric vehicle rescue service 1302 shown in
A customer/user, using the client device 22, can connect to the remote server 1300 via the EVR app 247 to request vehicle rescue services from the electric vehicle rescue service 1302. The customer/user may be a driver or passenger of the disabled vehicle 105. In an embodiment, the remote server 1300 can determine the location of the requester (e.g., the customer/user) and can further locate service providers (e.g., rescue vehicle 110) near the requester. The requester can then select a service provider to provide rescue services for the disabled vehicle 105. The selected service provider can accept the request and the rescue vehicle 110 can be dispatched to the location of the requester. Note that in some instances the selected service provider may simply be the electric vehicle rescue service 1302. In other instances, the electric vehicle rescue service 1302 may act as a kind of clearinghouse to refer the requester to a particular selected service provider. The ‘selection’ of the service provider may be made by the electric vehicle rescue service 1302 and/or by the requester through the EVR app 247.
