| 摘 要： | 锂电池快速充电是电动汽车的研究重点,快速且深度的充电使电动汽车的使用更加便捷,目前锂电池快速充电的研究仍处于起步阶段,现已提出的快速充电方案种类繁多,但具体原理和应用细则没有得到详细的研究。针对此问题,对电池等效电路PNGV模型进行改进并辨识参数,降低模型误差,对充电过程建立数学模型,结合带精英策略的快速非支配排序遗传算法(NSGA-II),对快速充电方案进行多目标优化,得到Pareto前端即为快速充电的具体优化方案库。在方案库中可根据具体充电需要选择相应充电方案,比如在特定时间下选择快速充电方案,保证充电深度达最深。快速充电优化的方案通过NEWARE电池测试平台进行实验验证,实验结果证实了该方案的可行性。

| Abstract: | Selective harmonic eliminated PWM(SHEPWM) strategy has a lot advantages, such as lower equivalent switching frequency, higher quality of the output voltage and lower loss, etc. The implementation of SHEPWM on T-type three-level inverter was studied. Firstly, the principles of selecting the number of switching angles were introduced, and the control loop was analyzed and designed. On this basis, the current THD and efficiency of SHEPWM and SVPWM were compared, and the influences of grid harmonic on power quality were analyzed. Results were validated by experiment on a 10 kW T-type three-level inverter platform. |

| Keywords: | selective harmonic eliminated PWM(SHEPWM) space vector modulation(SVM) T-type three-level power quality efficiency |
