Double-gun simultaneous charging method

Abstract

The invention discloses a double-gun simultaneous charging method. The double-gun simultaneous charging method includes the following steps: a charging gun A and a charging gun B are in communication, and whether the charging gun A and the charging gun B can find each other or not is detected; the charging gun A and the charging gun B are in communication with an electric vehicle, the one, responding to communication, of the charging gun A and the charging gun B serves as a main gun, and the other one, not responding to communication, of the charging gun A and the charging gun B serves as a salver gun; a charging gun A control unit and a charging gun B control unit are in mutual communication; a main gun control unit is in communication with the electric vehicle to obtain charging demand information; the main gun control unit informs a power distribution unit of the main gun control unit and a power distribution unit of a salver gun control unit according to the received charging demand information; the power distribution unit of the main gun control unit and the power distribution unit of the salver gun control unit send corresponding current and voltage signals to the corresponding charging guns; and the charging gun A and the charging gun B simultaneously charge the electric vehicle. According to the double-gun simultaneous charging method, a charging pile with double guns or multiple guns can be well compatible with the electric vehicle with double-gun simultaneous charging interfaces.

Description

technical field [0001] The invention relates to the technical field of electric vehicle charging, in particular to a method for simultaneously charging two guns. Background technique [0002] With the continuous development of new energy technology, there are more and more electric vehicles. In order to speed up the charging speed, some electric vehicles are equipped with dual-gun simultaneous charging interfaces, but because there is no unified standard, some charging piles with double guns or even multiple guns It is not well compatible with electric vehicles with the above-mentioned dual-gun simultaneous charging interface. [0003] Therefore, the prior art needs to be improved and improved. Contents of the invention [0004] In view of the above-mentioned problems in the prior art, the purpose of the present invention is to provide a simultaneous charging method for two guns, which improves the compatibility of existing charging piles. [0005] To achieve the above o...
