A battery/ultra-capacitor hybrid energy storage system is proposed for mini pure electric vehicle, the power distri-bution control strategy based on fuzzy control theory is used for pure electric vehicle. Fuzzy controller is designed for vehicle power system structure. Taking the bus current of driving motor and SOC of ultra capacitor as input, the fuzzy controller calcu-lates optimal output current of ultra capacitor, and reasonably distributes power between the battery and ultra capacitor. The hybrid energy storage system simulation is modeled on the platform of the Matlab-Simulink. The simulation results show that the proposed power allocation strategy can effectively allocate the composite power output of the battery and ultra capacitor, im-prove working condition of the accumulator, and increase the energy utilization.
