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.
