摘　　要：随着电动汽车的迅速普及,电动汽车对充电技术的要求提出了越来越高的要求。本文对传统的恒流恒压充电算法进行了分析研究和仿真,提出了变脉冲的充电算法。通过研究各种方法在充电过程中电池电压和电流的变化规律,将充电的时间和温升作为衡量指标,与恒流充电算法、恒压充电算法、固定脉冲充电算法进行比较。仿真结果表明,变脉冲充电算法相较于其他充电算法有较好的充电效果。The charging algorithm is particularly important for the improvement of charging effect of electric vehicles. In this paper, the traditional constant current and constant voltage charging algorithm is analyzed, studied and simulated, and a variable pulse charging algorithm is proposed. By studying the variation law of battery voltage and current in the charging process of various algorithms, tak-ing the charging time and temperature rise as the measurement index, it is compared with constant current charging algorithm, constant voltage charging algorithm and fixed pulse charging algorithm. The simulation results show that the variable pulse charging algorithm has better charging effect than other charging algorithms.
