电动汽车智能充电器的设计与实现

Design and Realization of Electric Vehicle Charger

此处采用高频开关电源技术设计了电动汽车充电器电路拓扑,并提出改进型变电流间歇充电方法,可按预置自动控制充电过程,使充电电流在总体上逼近蓄电池可接受充电电流曲线,减弱了蓄电池充电极化影响。实验结果表明,该充电机具有体积小、重量轻、使用简单、免维护、高效节能等优点。

The circuit topology of electromobile charger is designed with high-frequency switch power technology, variable current charger method with interrupt and time limit is proposed after researching charger principle and many kinds of charger methods.Variable current charger method can make charger current follow an acceptable curve and polarization is reduced.The experimental results show that this intelligent batteries charger has many advantages such as small cubage, light weight, easy use, no maintenance and high efficiency.
