Detailed Description
The following detailed description of specific embodiments of the present disclosure is provided in connection with the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the present disclosure, are given by way of illustration and explanation only, not limitation.
The inventor of the application finds that the communication of domestic electric vehicles is mainly based on CAN communication, and the charging of export vehicles is mainly based on PLC communication. Therefore, the exit vehicle type needs to be provided with a communication conversion module for converting the CAN protocol into the PLC protocol. However, at present, the communication conversion module cannot realize that alternating current and direct current share one communication conversion module, a direct current quick charging port and an European standard alternating current charging port need to be configured for an outlet vehicle type which needs both quick charging and slow charging, and the appearance of the whole vehicle is influenced because the two sets of charging ports are difficult to arrange.
Fig. 1 is a schematic circuit diagram of a vehicle connected to a charging cabinet according to an exemplary embodiment of the present disclosure, so as to solve the technical problem in the related art that two charging ports are required to be configured for a vehicle type requiring both fast charging and slow charging.
