BRIEF DESCRIPTION OF THE DRAWINGS
[0007] Aspects of the present disclosure are described in the detailed description which follows, in reference to the noted plurality of drawings by way of non-limiting examples of exemplary embodiments of the present disclosure.

DETAILED DESCRIPTION OF ASPECTS OF THE INVENTION
[0015] The present disclosure relates generally to an electrical adapter and, more particularly, to an adapter for electric vehicle supply equipment (EVSE). More specifically, in embodiments, the adapter for the electric vehicle supply equipment (EVSE) (hereinafter referred to as “electric vehicle charging system” or “charging system”) is a comprehensive system which includes both a hardware component and a software component(s) (e.g., controller) that allows electric vehicle (EV) owners to offer use (i.e., in the form of a short term lease) of their personal charging systems to other users of electric vehicles or other devices suitable for connection to such charging systems. For example, the hardware component comprises, amongst other systems, a metered connection adapter which can be connected to both a legacy personal charging system and an electric vehicle; whereas, the software component can be a controller that provides management services such as, e.g., communications, metering, and monitoring of the charging system.
[0016] Advantageously, the adapter described herein provides benefits to drivers of electric vehicles (EV) by increasing the availability of charging locations and, hence, providing an alternative to the national charging networks, e.g., Tesla Superchargers, Electrify America, etc. Moreover, the adapter provides benefits to the environment by encouraging green energy producers with excess energy to market to EV drivers, while also having the potential to quickly reduce range anxiety among potential EV buyers as charging locations will increase with every available adapter. The adapters also benefit the owners of personal charging systems as they will often be able to offset their costs of such system by leasing their charging system at a rate that may be higher than the current rate they pay for electricity.
Hardware Infrastructure

[0018] Still referring to
[0019] In embodiments, female electrical connector 104 is designed, configured and structured to connect to an existing electrical connector of a charging system such as, e.g., Electric Vehicle Supply Equipment (EVSE); whereas, male connector 106 is designed, configured and structured to plug into different electric vehicles. The male connector 104 can include any type of male connector (e.g., plug) that is compatible with existing electric vehicles. For example, both female connector 104 and male connector 106 can include various connection types such as a J1772-2009 connection type shown in
[0020] As should be understood by those of skill in the art, EVSE supplies electric energy to charge plug-in electric vehicles. The EVSE includes a protocol to keep the user and electric vehicle safe while charging. By using the same pin/plug configuration for female electrical connector 104 and male connector 106, these same protocols will be provided by adapter 100. For example, using two-way communication between the charging system and electric vehicle (which now flows through adapter 100), the correct charging current is set based on the maximum current the charging system can provide as well as the maximum current the electric vehicle can receive. As part of the protocol, a safety lock-out exists, preventing current from flowing when the charging system is not connected to the electric vehicle. In this way, adapter 100 ensures that if a cable is not correctly inserted, power will not flow through it. The adapter 100 can also detect hardware faults, disconnecting the power and preventing battery damage, electrical shorts or fire. The manner in which these safety features are provided are described in more detail with respect to
[0021] Again referring to
[0022]
[0023] In embodiments, restricting band 110b can be a stainless steel band that is housed within housing 102 such that it is not accessible from outside of housing 102. As shown, restricting band 110b surrounds socket inner wall squeeze pad 110a and includes a plurality of slots 110b′ which are engaged by a screw drive 110c. In operation, restricting band 110b can be tightened by rotating screw drive 110c in a clockwise direction through a cylinder hole 110d extending within housing 102. As should be understood by those of ordinary skill in the art, screw drive 110c will engage with slots 110b′ and, as screw drive 110c rotates, the circumference of restricting band 110b will become smaller, thereby locking female socket inner wall squeeze pad 110a to the connection type (e.g., plug) by a friction fit connection. A cylinder lock 110e can be used to lock restricting band 110b, e.g., prevent access to or rotation of screw drive 110c.
[0024]
[0025]
[0026]
[0027]
[0028] In embodiments, the Proximity Pilot pin provides proximity detection which may comprise a signal to the vehicle's control system so it can prevent movement while connected to the electric vehicle supply equipment (e.g., the charging station), and signals a latch release button to the vehicle. The Control pilot provides a communication line used to signal a charging level between the vehicle and the charging system. For example, a 1 kHz square wave at ±12 volts generated by the charging system, e.g., EVSE, on the control pilot line can detect the presence of the vehicle, communicate the maximum allowable charging current, and control charging begin/end times. The charging can be four levels of charging: AC Level 1, AC Level 2, DC Level 1, and DC Level 2.
[0029] As with the J1772 standard, adapter 100 also includes several levels of shock protection, ensuring the safety of charging even in wet conditions. For example, physically, the connection pins are isolated on the interior of the connector when mated, ensuring no physical access to those pins. When not mated, connectors have no power voltages at the pins, and charging power does not flow until commanded by the vehicle. The ground pin is of the first-make, last-break variety. If the plug is in the charging port of the vehicle and charging, and it is removed, the shorter control pilot pin will break first causing the power relay in the charging system to open, stopping current flow to adapter 100. The proximity detection pin is also connected to a switch that is triggered upon pressing the physical disconnect button when removing the connector from the vehicle. This causes the resistance to change on the proximity pin which commands the vehicle's onboard charger to stop drawing current immediately. The vehicle can then release the control pilot which will cause the power relay to release.
Computing Infrastructure and Controller
[0030] In embodiments, adapter 100 also includes certain control functions which may be implemented as a controller in a computing infrastructure. In embodiments, the controller manages electric flow within the adapter, e.g., between the male connector and the female connector, to an electric vehicle. Implementations of the present disclosure may be a system, a method, and/or a computer program product (e.g., software modules or controller). The computer program product may include a computer readable storage medium (or media) having computer readable program instructions thereon for causing a processor to carry out aspects of the present disclosure.
[0031] More specifically,
[0032] As shown in
[0033] The bus 510 permits communication among the components of computing device 505. For example, bus 510 may be any of several types of bus structures including a memory bus or memory controller, a peripheral bus, and a local bus using any of a variety of bus architectures to provide one or more wired or wireless communication links or paths for transferring data and/or power to, from, or between various other components of computing device 505.
[0034] The processor 555 may be one or more processors or microprocessors that include any processing circuitry operative to interpret and execute computer readable program instructions, such as program instructions for controlling the operation and performance of one or more of the various other components of computing device 505. In embodiments, processor 555 interprets and executes the processes, steps, functions, and/or operations of the present disclosure, which may be operatively implemented by the computer readable program instructions. For example, processor 555 enables computing device 505 to provide control functions of adapter 100 including, e.g., communication, security, messaging, metering of electricity, monitoring, management (including financial transactions) and other operability and safety features as described herein.
[0035] In embodiments, processor 555 may receive input signals from one or more input devices 530 and/or drive output signals through one or more output devices 535. The input devices 530 may be, for example, user interface 112 of adapter 100 or a remote source (e.g., computing device of the owner of the charging system or a driver of an electric vehicle) through a communication protocol as is known to those of skill in the art such that no further description is required for a complete understanding of the present disclosure. The output devices 535 can be, for example, any display device, e.g., screen of user interface 112, as is known to those of skill in the art such that no further description is required for a complete understanding of the present disclosure.
[0036] The storage device 520 may include removable/non-removable, volatile/non-volatile computer readable media, such as, but not limited to, non-transitory media such as magnetic and/or optical recording media and their corresponding drives. The drives and their associated computer readable media provide for storage of computer readable program instructions, data structures, program modules and other data for operation of computing device 505 in accordance with the different aspects of the present disclosure. In embodiments, storage device 520 may store operating system 545, application programs 550, and program data 555 in accordance with aspects of the present disclosure.
[0037] The system memory 525 may include one or more storage mediums, including for example, non-transitory media such as flash memory, permanent memory such as read-only memory (“ROM”), semi-permanent memory such as random access memory (“RAM”), any other suitable type of storage component, or any combination thereof. In some embodiments, an input/output system 560 (BIOS) including the basic routines that help to transfer information between the various other components of computing device 505, such as during start-up, may be stored in the ROM. Additionally, data and/or program modules 565, such as at least a portion of operating system 545, application programs 550, and/or program data 555, that are accessible to and/or presently being operated on by processor 555 may be contained in the RAM.
[0038] The communication interface 540 may include any transceiver-like mechanism (e.g., a network interface, a network adapter, a modem, or combinations thereof) that enables computing device 505 to communicate with remote devices or systems. The remote devices or systems may be within a networked environment, e.g., cloud environment. These remote devices or systems may be a computing device of the owner of the charging system or a driver of the electric vehicle itself. For example, computing device 505 may be connected to remote devices or systems via one or more local area networks (LAN), one or more wide area networks (WAN), WiFi or Bluetooth enabled technologies using communication interface 540.
[0039] In more specific embodiments, communication interface 540 allows both the owner of the charging system and driver of an electric vehicle to communicate with adapter 100, as well as providing Internet capabilities to adapter 100. For example, communication interface 540 can provide the location information of the charging system to the driver of the electric vehicle, in addition to providing the ability to make reservations for the charging system. In another example, communication interface 540 allows adapter 100 to automatically communicate directly with the electric vehicle upon connection to the adapter 100 (by detection of the proximity pin as an example) including, for example, providing a proper access code (e.g., UserID or PIN code) via a handshake protocol to authorize use of the charging system. In embodiments, the proper access code (e.g., UserID or PIN code) can be provided to the driver of the electric vehicle upon making a reservation. Also, in embodiments, the driver can enter the access code, ID or other required information manually using user interface 112 or remotely by use of a WiFi or Bluetooth enabled mobile device, with or without a reservation.
[0040] In addition, communication interface 540 allows the owner of the charging system to provide user messages or status of the charging system (e.g., available, off-line, in use, estimated time available to full charge, last connection time, error messages, etc.), compatibility and charge infrastructure, charge rates and pricing, power source (e.g., renewable type, grid, etc.) and other information that the user (e.g., driver of the electric vehicle) could filter and sort by to select appropriate charging locations, amongst other information. Moreover, communication interface 540 permits other monitoring, metering and financial transactions.
[0041] The computing device 505 may also perform other tasks (e.g., process, steps, methods and/or functionality) in response to processor 555 executing program instructions contained in a computer readable medium, such as system memory 525. These tasks include, for example, managing meter and payment data from adapter 100 and conduct the financial transaction based on the reservations made, electricity transferred and other specifics of the transaction. Payment would be via linked credit card, bank account or third party pay system (e.g., PayPal, FordPass, etc.). The computing device 505 can also provide metering capabilities, e.g., meter the start and stop of current flow, and a monitoring capability that would determine the status and security of the charge port. For example, the monitoring capability would prevent theft or unauthorized access of the charging system. In addition, computing device 505 can provide a management system that would coordinate the above functions. The computing device 505 can also provide other features as noted, for example, with respect to functionality/capability described with respect to
[0042] The program instructions may be read into system memory 525 from another computer readable medium, such as data storage device 520, or from another device via the communication interface 540 or server within or outside of a cloud environment. In embodiments, an operator may interact with computing device 505 via the one or more input devices 530 and/or the one or more output devices 535 to facilitate performance of the tasks and/or realize the end results of such tasks in accordance with aspects of the present disclosure. In additional or alternative embodiments, hardwired circuitry may be used in place of or in combination with the program instructions to implement the tasks, e.g., steps, methods and/or functionality, consistent with the different aspects of the present disclosure. Thus, the steps, methods and/or functionality disclosed herein can be implemented in any combination of hardware circuitry and software.
