An AC charging system for electric vehicles, which cooperates with a power grid, includes a power detecting module, a local power supplying module, and a local charging control module. The power detecting module is coupled with a second area power converting device of the power grid to generate power parameters. The local power supplying module is coupled to the power output side of the second area power converting device of the power grid for outputting a controllable power source to the electric vehicle. The local charging control module is coupled to the power detecting module and the local power supplying module, and controls each controllable power source provided by the local power supplying module according to power parameters. Accordingly, when a large number of electric vehicles use AC charging at the same time, it can avoid the power supply of the grid being affected by the overload of electricity.

An ECU performs processing including: a step of obtaining a pilot signal CPLT and a connector connection signal PISW; a step of determining, when a connector is attached, a type of the connector; a step of controlling, when there is a function corresponding to the type of the attached connector, the connector to be set to a lock state; a step of performing control corresponding to the attached connector; and a step of maintaining, when there is no function corresponding to the type of the attached connector, an unlock state of the connector.

The disclosure relates to an electrically operated vehicle having an electrical charging cable, by which a vehicle-side accumulator is chargeable by a vehicle-external power supply network in a charging procedure, wherein the charging cable can be unplugged from a vehicle-side terminal at least after completion of the charging procedure, in particular independently and without locking. According to the disclosure, the vehicle and/or the charging cable has a check function, which enables a charging cable usage if a usage authorization is present and blocks the charging cable usage if a usage authorization is not present.

A charge port assembly includes a port, an iris door movable to expose the port, and a motorized actuating assembly configured to move the iris door between a closed position in which the port is concealed and an open position in which the port is exposed. The iris door may be automatically dilated to the open position in response to a predefined prompt from an authorized user or if a charging cord is approaching the charge port assembly.

A method for communicating between an electric vehicle and a charging station for electrically charging at least one energy storage device of the electric vehicle. The electric vehicle is connected to the charging station during the charging process by a lockable mechanical coupling between a terminal of charging cable connected to the vehicle and a terminal of the charging station. Charging current is fed from the charging station through the charging cable. Information is transferred in the course of the charging process based on a communication between the electric vehicle and the charging station. The information includes a signal transmitted from the electric vehicle to the charging station for locking and/or unlocking the mechanical coupling. The signal triggers the locking and/or unlocking of the mechanical coupling between the terminal of the charging cable and the terminal at the charging station.

The information includes a signal transmitted from the electric vehicle to the charging station for locking and/or unlocking the mechanical coupling. The signal triggers the locking and/or unlocking of the mechanical coupling between the terminal of the charging cable and the terminal at the charging station.

A power conversion system includes a power conversion device, a connector, and a processing module. The power conversion device is connected to a power system. The attached state and the unattached state of the connector relative to a connecting port that is provided in an apparatus having a battery mounted therein can be selected. The processing module is configured to determine that a malfunction has occurred when a voltage is applied to a portion that electrically connects the connector and the connecting port in a period in which transmission of electric power with respect to the battery is stopped.

The present disclosure provides an inlet control system and apparatus for an electric vehicle. It is an object of the present disclosure to provide an inlet control system and apparatus for an electric vehicle that permit the connector of the charging cable to be released from the inlet of the electric vehicle connected thereto only when an authorized user having a release control apparatus is adjacent to the electric vehicle regardless of whether one end of the charging cable connected to a power source is removed or not and prohibit release of the connector of the charging cable from the inlet of the electric vehicle when the user having the release control apparatus moves away from the electric vehicle.

A vehicle charging system includes a locking mechanism to secure a charge plug to a charge port of a vehicle. The system includes a wireless transceiver and a near field communication transceiver. The system further includes a controller programmed to, responsive to receiving a request to disengage the locking mechanism during charging, send the request to a vehicle owner via the wireless transceiver, and, responsive to receiving an unlock command via the wireless transceiver, disengage the locking mechanism.
