摘　　要：对不同荷电态的电动自行车用铅酸蓄电池组进行了并联充放电过程的研究。结果表明:流经各组电池的电流是按照电池组的荷电态而自动调配的。在充放电过程中,原来荷电态较高的电池组充(放)电电流由小(大)逐步增加(减小);原来荷电态较低的电池组充(放)电电流由大(小)逐步减小(增大),最终各个电池组的充(放)电电流趋于一致。实验同时还证实了恒电压并联充电可以改善蓄电池组的均匀性,有利于延长蓄电池组的使用寿命。The parallel charge-discharge process of VRLA batteries for electric bicycle with different state of charge （SOC） was studied. The results showed that the current flowing to batteries was distributed automatically according to SOC. During the charge-discharge process, the charge （discharge） current of batteries having higher SOC would be smaller （hlgher）, then increased （decreased） gradually; but the charge （discharge） current of batteries having lower SOC would be higher （smaller）, then decreased （increased） as above. Finally, the charge （discharge） current of the batteries would become uniform. The experimental results showed that the parallel charge was favorable to improve the uniformity of batteries and prolong the service llfe of batteries.
