At this time, the whole pile system enters the charging state of at least one charging muzzle.
在至少1个充电枪口充电状态时，当有充电枪对应的车辆充满，分控板获取车辆充满信息并上报系统控制单元，结束充电。此时系统控制单元可以判断是否有至少1个充电口在充电，如果是否，则整桩转为待机状态，如果是，则整桩由回到至少1个充电枪口充电状态。When at least one charging gun is in the charging state, when the vehicle corresponding to the charging gun is fully charged, the sub-control board obtains the vehicle full information and reports it to the system control unit to end the charging. At this time, the system control unit can judge whether there is at least one charging port charging, if not, then the whole pile turns to the standby state, if yes, then the whole pile returns to the charging state of at least one charging port.
总的来说，在本申请实施例中，在至少1个充电枪口充电状态时，当再次有充电枪插枪充电，相对应的分控板获取车辆需求电压电流信息，并上报系统控制单元。系统控制单元根据当前正再充电接口总体需求，重新分配转换模块，系统控制单元关机相应正在充电的相应模块分配给刚插的充电枪，最后由分控板控制对应的开关接触器组输出。此时整桩系统再次进入至少1个充电枪口充电状态。In general, in the embodiment of this application, when at least one charging gun is in the charging state, when the charging gun is plugged in for charging again, the corresponding sub-control board obtains the vehicle's required voltage and current information, and reports it to the system control unit . The system control unit redistributes the conversion modules according to the overall requirements of the current charging interface. The system control unit shuts down and assigns the corresponding modules that are being charged to the newly inserted charging guns. Finally, the sub-control board controls the output of the corresponding switch contactor group. At this time, the whole pile system enters the charging state of at least one charging muzzle again.
