摘要
提出了一种采用大电流充电时能使充电曲线更平滑的方法。充电电流既可来自于电网也可由太阳能光伏电池提供。结合运行数据,利用光伏发电量较大且稳定的时间区段对锂离子电池充电。通过仿真验证了大电流平滑充电可提高蓄电池的充电效率,从而可延长蓄电池的使用寿命。
This paper presented a high current charging method which can make the charging curve more smooth. The charging current comes from both grid or photovoltaics. Based on operating data to charge Li-ion batteries while the photovohaics has high and stable power. The simulation results show that using high current level to charge batteries can increase the efficiency and make the batteries work longer.
