The invention provides an electric vehicle and a redundant system thereof, and relates to the field of electric vehicles. The redundant system comprises a vehicle control unit, a motor driving circuit, a hydraulic driving circuit, a pneumatic driving circuit, an auxiliary power supply connecting circuit and a power supply connecting circuit. Each circuit is provided with two input ends which are electrically connected with two power batteries of the electric vehicle respectively. The output end of the motor driving circuit is used for being electrically connected to a first motor controller and a second motor controller of the electric vehicle. The output end of the hydraulic drive circuit is used for being electrically connected to a first hydraulic pump and a second hydraulic pump of the electric vehicle. The output end of the air pressure driving circuit is used for being electrically connected to a first air compressor and a second air compressor of the electric vehicle. The output end of the auxiliary power supply connecting circuit is electrically connected with an auxiliary power supply of the electric vehicle. The output end of the power supply connection circuit is electrically connected to a mains supply output interface of the electric vehicle. And when a certain part is damaged, the electric vehicle can still work.

    本发明提供了一种电动车及其冗余系统,涉及电动车领域。其中,这种冗余系统包含整车控制器,电机驱动电路、液压驱动电路、气压驱动电路、辅助电源连接电路和供电连接电路。上述电路均具有两个输入端,分别和电动车的两个动力电池电连接。电机驱动电路的输出端分别用以电气连接于电动车的第一电机控制器和第二电机控制器。液压驱动电路的输出端分别用以电气连接于电动车的第一液压泵和第二液压泵。气压驱动电路的输出端分别用以电气连接于电动车的第一空压机和第二空压机。辅助电源连接电路的输出端用以电气连接于电动车的辅助电源。供电连接电路的输出端用以电气连接于电动车的市电输出接口。当某一部分损坏时仍能保证电动车工作。
