Abstract:

In order to improve the energy efficiency of the power supply system of hybrid electric vehicle (HEV), an energy management strategy based on adaptive filter is proposed. Firstly, the hybrid power supply system and the bi-directional DC/DC converter of HEV are modeled. Secondly, the adaptive law based on power-split is selected and the novel hybrid power adaptive energy management strategy is designed. Finally, the effectiveness of the proposed method is verified by the simulation experiment under different working conditions. The experimental results show that, the proposed method can transmit power of hybrid power system of HEV effectively to achieve high energy utilization.

摘要： 为提高混合动力车辆复合电源能量利用效率，提出一种基于自适应滤波方法的混合动力车辆（Hybrid Electric Vehicles, HEV）复合电源能量管理策略。首先，对HEV复合电源以及双向DC/DC变换器进行建模；然后，采用基于功率分流法的自适应率，设计得到新的复合电源自适应能量管理策略；最后，通过不同工况下的仿真实验，验证该方法的有效性。仿真结果表明，该方法能够有效分配HEV复合电源的功率，该策略具有能量利用率高的特点。
