The invention discloses a charging control method for double-gun parallel charging of an electric automobile. The method supports parallel charging of two guns of a single pile and combined parallel charging of two guns of different piles. The method comprises the following steps that after a user turns on a parallel charging switch, a system searches a parallel charging pile and configures the number of the parallel charging pile, or otherwise, parallel charging of a single pile is regarded, and searching of a parallel charging pile in the network is not carried out; after the double-pile parallel charging mode starts charging, the main pile sends a charging starting instruction to the parallel charging pile and sends a charging instruction to the main gun at the same time, if the main gun fails to start, a charging stopping instruction is sent to the parallel charging pile, and if the auxiliary gun fails to start and the parallel charging pile sends a starting completion frame to themain pile, the main pile continues charging; after the charging is successfully started, the main gun receives the charging information (a one-way message, and the main pile does not send the charging information to the parallel charging pile) of the auxiliary gun, combines the information and displays the combined information to a user; in the charging process, the main gun stops charging and sends a stop instruction to the parallel charging pile, after the parallel charging pile receives the instruction, charging is stopped, meanwhile, settlement data are sent to the main gun, and after themain gun receives the settlement data, orders are integrated to complete charging. Double guns between single piles or double guns between different piles can meet the requirement for simultaneous charging of electric vehicles with double-gun simultaneous charging interfaces, the charging efficiency is improved, and the charging time is shortened.

    本发明公开了一种电动汽车双枪并充的充电控制方法,此方法支持单一桩的两把枪的并充以及不同桩的两把枪的联合并充。包括以下步骤:用户开启并充开关后,系统会搜索并充桩并配置并充桩的桩编号,否则视为单一桩的并充,不会在网络中搜索并充桩;双桩并充模式启动充电后,主桩会向并充桩发送启动充电指令,同时也会给主枪下发充电指令,若主枪启动失败,会发送停止充电指令给并充桩,若辅枪启动失败,并充桩会发送启动完成帧给主桩,主桩会继续充电;成功启动充电后,主枪会接收辅枪的充电信息(单向报文,主桩不发送充电信息给并充桩),合并信息之后展示给用户;充电过程中,主枪结束充电,会向并充桩发送停止指令,并充桩收到指令后,结束充电,同时发送结算数据给主枪,主枪收到结算数据后,整合订单完成充电。本发明能够使得单一桩之间的双枪或不同桩之间的双枪满足具有双枪同时充电接口的电动汽车同时充电,提高充电效率,减少充电时间。
