摘要
混合储能系统作为新能源汽车的主要动力供给单元,其工作质量直接影响着整个汽车的运行状况。为了提高新能源汽车混合储能系统(HESS)的能量利用效率,避免能量浪费,文章介绍了新能源汽车HESS锂电池、直流-直流(DC-DC)转换器、超级电容等结构的组成,对新能源汽车HESS能量控制特点进行了分析,探索了基于优化车辆驾驶速度的模糊控制策略,从而在提升HESS能量利用效果的同时防止了过度充放电现象的发生,促进了新能源车辆的长远发展。
As the main power supply unit of new energy vehicle,the working quality of hybrid energy storage system directly affects the overall operation of the vehicle.In order to improve the energy utilization efficiency of the hybrid energy storage system(HESS)for new energy vehicle and avoid energy waste,this paper introduces the composition of the lithium battery,direct current-direct current(DC-DC)converter,super capacitor and other structures of HESS for new energy vehicle,analyzes the energy control characteristics of the HESS for new energy vehicle,and explores the fuzzy control strategy based on optimizing vehicle driving speed.While improving the energy utilization effect of HESS,it also prevents the occurrence of excessive charge and discharge,and promotes the long-term development of new energy vehicle.
