Electric vehicle charger device

Abstract

The invention relates to an electric vehicle charger device, which comprises a controller module, an interaction module, an identification module, a receiving module and a charging module, wherein one end of the controller module is connected with a power grid, and the other end of the controller module is connected with the interaction module; the identification module and the receiving module are connected with a vehicle-mounted battery management system of an electric vehicle by the interaction module respectively; the charging module is connected with a vehicle-mounted battery system of the electric vehicle by the interaction module; the controller module is used for realizing the regulation output of voltage and power; the interaction module is used for establishing energy and signal transmission relationships with the electric vehicle and a power grid; the identification module is used for identifying whether the electric vehicle meets safety conditions or not; the receiving module is used for receiving information about the battery power in the vehicle-mounted battery management system of the electric vehicle; and the charging module is used for charging the vehicle-mounted battery system of the electric vehicle with the power. The electric vehicle charger device meets characteristic requirements on safety, metering, control and convenience of operations in a charging process.

Description

technical field [0001] The invention relates to a charger device, in particular to an electric vehicle charger device. Background technique [0002] People pay more and more attention to environmental problems. As a non-polluting means of transportation, electric vehicles are of great significance to building a sustainable society and protecting our living homeland. The development of electric vehicles depends on the construction of charging stations, and the excellent charging mode of electric vehicles in charging stations will greatly promote the popularization of electric vehicles.

Problems solved by technology

[0003] At present, charging devices for electric vehicles have not been popularized yet, and national standards for charging interfaces have not yet been released. The charging devices introduced by some manufacturers are mainly charging connectors, which have large differences in structure and are expensive.

The current common slow charging solution is to arrange the charger in the car, and use a charging connector and wiring harness to transmit 220V AC power to the charger. The charging start and stop process is realized through the CAN communication between the charger and the vehicle controller. , this solution lacks measures to judge whether the leakage protector and the connection of the charging connector are sufficient. Obviously, this solution has potential safety hazards
