The invention discloses a battery replacement control method for a pure electric commercial vehicle, which comprises the following steps that: after the vehicle enters a battery replacement station, a battery replacement identification system detects whether the vehicle is parked in place or not; if the vehicle is parked in place, the upper computer sends a signal that the vehicle enters a battery replacement position to the vehicle, a BMS battery system of the vehicle enters a battery replacement mode, and the BMS battery system judges whether the vehicle is powered off or not. And if the BMS battery system judges that the vehicle is powered off, the BMS battery system controls a battery cabin door motor to execute a cabin opening instruction. And the upper computer sends a battery replacement signal to the BMS battery system so as to carry out battery replacement operation. And after battery replacement is completed, the upper computer sends a battery replacement completion instruction to the BMS battery system, and a cabin closing instruction is executed. And after cabin closing is completed, battery replacement is finished, and the vehicle is driven away at the moment. Therefore, according to the battery replacement control method for the pure electric commercial vehicle, the battery can be quickly replaced, the energy of the vehicle can be quickly supplemented, time and labor are saved, and the labor cost is reduced.
本发明公开了一种纯电动商用汽车换电控制方法,包括:车辆进入换电站后,换电识别系统检测车辆是否停靠到位。若车辆已停靠到位,上位机向车辆发送已经入换电位置信号,车辆的BMS电池系统进入换电模式,且BMS电池系统判断车辆是否已下电。若BMS电池系统判断车辆已下电,则BMS电池系统控制电池舱门电机执行开舱指令。上位机给BMS电池系统发送更换电池信号,从而进行更换电池操作。当更换电池完成后,上位机向BMS电池系统发送换电完成、执行关舱指令。当关舱完成后,更换电池结束,此时车辆驶离。借此,本发明的纯电动商用汽车换电控制方法,可实现快速更换电池,实现车辆能量的快速补充,且省时省力,减少了人力成本。
