An electric vehicle intelligent charging device

Abstract

The invention discloses an intelligent charging device for an electric car, and the device comprises an AC charging line, an adapter line, and a vehicle charging control module. The AC charging line comprises a charging fun, a power input plug, and a cable control box. The power input plug comprises a detection power transmitting end and a detection power receiving end. One end of the adapter line is matched with the power input plug, and the other end of the adapter line is matched with the power supply. An adapter device comprises a short circuit line, which is connected with the detection power transmitting end and the detection power receiving end. A vehicle charging control module is connected with the power receiving end. The setting of the adapter line enables a single charging line to be able to adapt to various types of input currents, thereby reducing the space occupied by a plurality of charging lines. The shot circuit line is connected with the detection power transmitting end and the detection power receiving end, and the vehicle charging control module is connected with the detection power receiving end, thereby enabling the vehicle charging control module to be able to switch the corresponding input power through different signals of the detection power receiving end.

Description

technical field [0001] The invention relates to the technical field of electric vehicles, in particular to an intelligent charging device for electric vehicles. Background technique [0002] At present, electric vehicles generally use a 16A standard charging cable, one end is a standard 16A national standard plug, and the other end is a national standard 7-pin AC charging gun. There are many three-hole sockets, and there are few 16A three-hole sockets. Charging is inconvenient. If you directly use a 10A to 16A adapter socket, the vehicle can be connected to a household 10A socket, but the actual charging current is generally around 15A, which is much higher than 10A, the household wiring harness and socket are overloaded, which can easily accelerate the aging of the wiring harness and socket. One is matched with a 16A socket and the other is matched with a 10A socket, which can realize the charging of both power sources of the vehicle, but one car is equipped with two chargi...

Problems solved by technology

[0003] To this end, it is necessary to provide an electric vehicle intelligent charging device to solve the problem that the current electric vehicle charging line cannot be adapted to both 10A and 16A sockets at the same time, and using two charging lines respectively will increase the cost of the vehicle, occupy space, and cause excessive heat generation during long-term charging.
