The invention provides an automobile power system and a power supply control method thereof, and belongs to the technical field of automobile batteries. The power system comprises a super capacitor system, a power battery system and a fuel battery system which are connected in parallel, the parallel output ends of the super capacitor system, the power battery system and the fuel battery system are connected with the motor after passing through the DC/DC module; and the DC/DC module is used for converting current/voltage output by the super capacitor system and/or the power battery system and/or the fuel battery system into current/voltage required by the motor, so that the motor drives automobile wheels to move. The power system is long in service life, low in price, environmentally friendly and high in low-temperature reliability, the size of the power system can be reduced by adding the super-capacitor system, the maintenance cost is low, and the problems that an existing automobile power system is short in service life, high in price, inapplicable at low temperature, complex in structure, large in comprehensive size, high in long-term use maintenance cost and the like are solved.

    本公开提供一种汽车动力系统及其供电控制方法,属于汽车电池技术领域。该动力系统包括:相互并联的超级电容系统、动力电池系统、燃料电池系统;超级电容系统、动力电池系统和燃料电池系统的并联输出端通过DC/DC模块后连接电机;DC/DC模块用于将超级电容系统和/或动力电池系统和/或燃料电池系统输出的电流/电压变换为电机所需的电流/电压,以使电机驱动汽车车轮运动。本公开提供的动力系统使用寿命长、价格低、环保、低温可靠性高,增加超级电容系统能够减小动力系统体积,维护成本低,解决了现有的汽车动力系统使用寿命低,价格昂贵,低温不适用,结构复杂,综合体积大,长期使用维护成本高等问题。
