The invention discloses an electric vehicle circulating power supply system, which relates to the technical field of electric vehicle power supply and comprises a battery power supply module, a motor driving module, an auxiliary electrical equipment power supply module, a charging module, a battery management module and an electrical protection module. According to the invention, the power management module selects, switches and controls the power supply according to the energy requirements of different devices, carries out priority management on a plurality of auxiliary electrical devices when the auxiliary electrical devices operate at the same time, and achieves the efficient control and management of battery circulation power supply by setting the priority sequence. Discharging is stopped in time when the electric quantity of the battery is lower than a certain threshold value by controlling the discharging current and voltage and setting the low-electricity threshold value of the battery, so that over-discharging is prevented, the service life of the battery is protected, energy generated during braking is converted into electric energy, and the electric energy is stored in the battery, so that the endurance mileage of the vehicle is prolonged.
本发明公开了电动汽车循环供电系统,涉及电动汽车供电技术领域,包括电池供电模块、电动机驱动模块、辅助电气设备供电模块、充电模块、电池管理模块和电气保护模块。本发明通过电源管理模块根据不同设备的能量需求,对电源进行选择、切换和控制,并对多个辅助电气设备同时运行的情况下进行优先级管理,通过设定优先级顺序,实现电池循环供电的高效控制及管理,通过控制放电电流和电压并设定电池低电阈值,在电池电量低于一定阈值时及时停止放电,以防止过放,保护电池的寿命,通过将制动时产生的能量转化为电能,存储到电池中,以延长车辆的续航里程。
