Abstract: For the problem of shortened service life of the fuel cell vehicle due to frequent over-discharge and the rapid increase of economic cost caused by high power demand module, a control strategy model of energy management for fuel cell compensated power battery discharge based on micro-variable fuzzy logic control is proposed by combining fuel cell vehicle with power battery module. Through the secondary development and optimization of ADVISOR, the simulation results verify the rationality of the energy management control strategy of the fuel cell-battery hybrid model, which ensures the power and economic performance of the vehicle. In addition, the total energy utilization efficiency of the system at the end of the driving cycle is optimized. The results show that the fuel cell-battery hybrid vehicle based on micro-variable fuzzy logic control meets the requirements of power and the economic performance is improved.
