The invention discloses a battery replacement control circuit, a battery replacement control system and a battery replacement control method for an electric vehicle. The control system comprises the electric vehicle, a switch K1, a switch K2, a switch K3 and a switch K4. The controller is used for collecting the voltage VK of a rotating handle of the electric vehicle and the voltage of a main battery and controlling the on and off of the switch K1, the switch K2, the switch K3 and the switch K4; the main battery is used for supplying power to the electric vehicle; the boost charging module is used for boosting and charging the battery pack; a battery replacing device; the power supply is used for supplying power; compared with the prior art, through cooperation of the controller, the switch K1, the switch K2, the switch K3 and the switch K4, when the electric vehicle is in a downhill or sliding state, boosting charging can be conducted on the battery replacing device through the boosting charging module, and when a main battery of the electric vehicle is out of power, the battery replacing device can be adopted for supplying power to the electric vehicle; therefore, the problem of battery endurance in the meal delivery process of the electric vehicle is thoroughly solved.

    本发明公开了一种电动车换电控制电路、换电控制系统及换电控制方法,控制系统包括电动车、开关K1、开关K2、开关K3、开关K4;控制器,用于采集电动车的转把电压VK及主电池的电压,控制开关K1、开关K2、开关K3、开关K4的断开与导通;主电池,用于给电动车供电;升压充电模块,用于给换电宝升压充电;换电宝;用于给电动车供电;与现有技术相比,本发明能够通过控制器、开关K1、开关K2、开关K3、开关K4相配合,在电动车处于下坡或滑行状态时,通过升压充电模块给换电宝进行升压充电,在电动车的主电池没电时,可以采用换电宝给电动车供电,从而彻底解决电动车送餐过程中的电池续航问题。
