摘要
近年来,随着环境污染和石油资源的匮乏,发展具有零排放、零污染的纯电动汽车成为必然趋势,与传统车电气系统相比,电动汽车电气系统电压高达几百伏,工作时电流达到几十安培甚至几百安培,危及驾驶员和乘客安全,对电动汽车高压系统预充电进行研究,建立了预充电等效模型,设计了预充电控制策略及硬件电路,通过实验验证了预充电策略的正确。
In recent years, With environmental pollution and the lack of oil resources, it is an irresistible trend that developing pure e- lectric vehicle with zero emissions and zero pollution. Compare with traditional vehicles, pure electric vehicle' s electric system voltage up to a few hundred voltages, and currents up to tens or even hundreds of amperes, which endanger the safety of the driver and passen- gers. High voltage precharge of electric vehicle is studied in the paper, precharge equivalent model is set up, contol strategy and hard- ware circuit are designed, precharge contol strategy verified reasonably by experiment.
