摘 要：在基于动力电池SOC规则型能量控制策略基础上，提出基于整车动力需求的氢燃料电池跟随型策略，并进行MATLAB/Simulink仿真分析。结果表明，跟随型策略可有效稳定动力电池SOC区间，降低电池吞吐量，并使燃料电池摆脱长期处于低功率区间运行的状态。氢燃料电池和动力电池寿命可得到大幅提升。

YANG Kun, GUO Fenggang
Abstract: On the basis of the regular power control strategy based on SOC of power battery, the authors pro-pose the following-up strategy of hydrogen fuel cell based on vehicle power requirement,and carry out simulation analysis with MATLAB/Simulink. The results show that the follow-up strategy can effectively stabilize the SOC range of the power battery, reduce the battery throughput, and get the fuel cell out of the long-term low-power range operation. Therefore, the life of hydrogen fuel cell and power battery can be greatly improved.
