Abstract: An electric vehicle charger includes a processor. The processor is configured to identify a first temperature and a second temperature from a sensor. The processor is configured to determine a rate change of temperature based on at least the first temperature at the first time point and the second temperature at the second time point. The processor is configured to prevent a maximum temperature threshold for the electric vehicle charger from being reached. The processor being configured to prevent the maximum temperature threshold from being reached includes the processor being configured to control an output of the electric vehicle charger based on the determined rate change of temperature and a predicted time to maximum temperature threshold.

Abstract: An on-site device configured to be used with networked Electric Vehicle Supply Equipments (EVSEs) is provided to diagnose or recover an EVSE for configuration. The on-site device comprises a first coupler interface configured to electrically connect the on-site device to one or more EVSEs, a first communication interface to connect the on-site device to a short-range communication network on a wired network or on a wireless network. It further comprises a second communication interface to connect the on-site device to a long-range wireless communication network, a processor and a memory storing instructions that, when executed by the processor, cause the on-site device to: establish a communication connection with the EVSE and interface to the EVSE via a programmable logic controller (PLC) on a control pilot, Modbus RTU or other near-field communication (NFC), perform diagnostics to locally recover charging operation or network connectivity of EVSEs and further aid in remote maintenance.

Abstract: Systems and methods are provided for Electric Vehicle Supply Equipment (EVSE) system clock time synchronization based on a short-range wireless communication-based automated process. A system comprises a cellular mobile device having a short-range wireless communication capability to communicate with one or more EVSEs. The system further comprises a smart EVSE capable of gaining network connectivity, maintaining an EVSE system clock, and storing multiple days or months interval data logs and charging session data in order to provide reporting to a utility that allows retroactively calculating meter data and performing accurate billing to its customers such that the smart EVSE to synchronize time if power is lost when the network connectivity is down and to retrieve the interval data logs and the charging session data for updating to a cloud automatically to gain network connectivity for gaining an ability to perform Network Time Protocol (NTP) synchronization of the EVSE system clock.

Abstract: A bi-directional electric vehicle supply equipment (EVSE) is provided where the EVSE allows power transfer to and from an electric vehicle (EV). The EVSE comprises a coupler and an AFCI device including: a controller including a processor and a memory, circuitry and computer-readable firmware code stored in the memory which, when executed by the processor, causes the controller to: detect an arcing level of arcing between the coupler and a charge port of the EV or any other series or parallel arcing within the EVSE, compare the arcing level to a threshold level to determine a hazardous nature of arching, and analyze the arcing level to determine not only if it is currently hazardous but if it is likely to become hazardous in a near term and recommend repair or replacement of the coupler and the charge port before damage occurs.

Abstract: A network-based energy management system of managing electric vehicle (EV) charging network infrastructure is provided. The system comprises a gateway including one or more of an electric vehicle supply equipment (EVSE), a building automation system and any other independent controller. The gateway is configured for performing charging authorization, load management and/or demand response on an EVSE network using more than one communication channels including remote and/or local modes. The EVSE network includes two or more components from a group of components including a first EVSE, a controller, a second EVSE, the building automation system, a local server, a remote server and other energy management device.

Abstract: An electric vehicle supply equipment (EVSE) charging system includes an EVSE charging station that is configured to switch a power source between a first power source and a second power source based on a time of use or real-time energy pricing data from a utility. Switching additionally and/or optionally may be based on at least one of charging information and metering information. The first power source may be a renewable source and the second source may be the power grid. In this way, a smart electric vehicle supply equipment (EVSE) charging station may manage and optimize energy supply from a grid and a renewable source when charging an electric vehicle (EV) with the smart the EVSE charging station.
