The invention discloses a power battery system for a pure electric vehicle. The power battery system comprises a super capacitor battery pack, a storage battery pack and a super rapid charging and discharging management control system. The super rapid charging and discharging management control system is composed of a digital signal processor and a two-way boost-buck power supply converter. The super capacitor battery pack provides power needed in running of the vehicle and absorbs and stores input electric energy generated in running of the vehicle, and the capacitance electric quantity which the super capacitor battery pack can release is not smaller than 92% of the total capacitance battery capacity. When the storage battery pack is not fully charged, the super capacitor battery pack charges the storage battery; when the output voltage of the super capacitor battery pack is smaller than 24 V, the storage battery pack starts to supply power to the vehicle. The power battery system is simple in structure, low in cost and capable of achieving rapid charging and has important value for the development of the pure electric vehicle.
