The invention discloses a new energy vehicle power supply switching system which comprises a mains supply module, a power battery pack power supply module and a UPS module, the mains supply module and the power battery pack power supply module are connected to the input end of the UPS module in parallel, and the output end of the UPS module is connected with a new energy vehicle passenger area power utilization end; the UPS module includes a charger and an inverter, or includes a rectifier and an inverter. Electric power provided by the commercial power supply module or the power battery pack power supply module passes through the UPS module and then is output to the 220v power utilization end of the passenger area for power supply, in the power supply switching process of the commercial power supply module and the power battery pack power supply module, the UPS module continuously supplies power to power utilization equipment in a vehicle while stabilizing current, sudden power failure of the equipment is prevented, and the service life of the vehicle is prolonged. And meanwhile, electric appliance elements such as a capacitor in the electric equipment in the vehicle are prevented from being broken down due to the current open circuit condition in the power supply switching process.
本发明公开了一种新能源车供电切换系统,包括市电供电模块、动力电池组供电模块及UPS模块,市电供电模块及动力电池组供电模块并联于UPS模块的输入端,UPS模块的输出端与新能源车乘客区用电端连接;UPS模块包括充电器和逆变器,或者包括整流器和逆变器。本发明中市电供电模块或动力电池组供电模块提供的电力,经过UPS模块后再输出给乘客区220v用电端供电,在市电供电模块和动力电池组供电模块切换供电的过程中,UPS模块在稳流的同时持续为车内用电设备供电,防止设备突然断电,同时避免在切换供电的过程中造成的电流断路情况击穿车内用电设备中的电容等电器元件。
