The invention provides a vehicle power supply system. The system comprises a first supercapacitor, a second supercapacitor, a braking energy recovery unit, a battery and a control unit. The first super capacitor is used for storing electric energy provided by the braking energy recovery unit. And when the vehicle is in an accelerated driving state, the second supercapacitor supplies power to the motor. And when the vehicle is in a non-accelerated driving state, the battery supplies power to the motor. The vehicle power supply system adopts a hybrid power supply of the super capacitor and the battery, so that the recovery efficiency of the power supply system on braking energy can be improved, the vehicle has stronger rapid acceleration power performance during acceleration, the service life of the battery and the whole power supply system can be prolonged, and the use cost of the vehicle is reduced.
本申请提供了一种车辆供电系统,该系统包括第一超级电容器、第二超级电容器、制动能量回收单元、电池和控制单元。第一超级电容器用来储存制动能量回收单元提供的电能。当车辆处于加速行驶状态时,第二超级电容器为电机进行供电。当车辆处于非加速行驶状态时,电池为电机进行供电。该车辆供电系统采用超级电容器与电池的混合式电源,不仅能够提高供电系统对制动能量的回收效率,以及使在加速时车辆具备更强的急加速动力性能,还能延长电池和整个供电系统的寿命,降低车辆的使用成本。
