摘　　要：MH-Ni蓄电池组充放电性能的一致性主要表现在电压和电池容量的一致性,是因为制造工艺和材料的不一致等因素造成的。电池分选技术非常重要,采用内阻法、容量法、特性曲线法相结合,提高了MH-Ni蓄电池的一致性,即使在240A(3C)放电,电池组单体电压相差值也在20mV之内。Consistency of nickel mental hydride battery is mostly showed by consistency of voltage and capacity of the battery,which is caused by variance of fabricated techniques,materials and so on. Therefore, it is important to select battery module. Combination of resistance method,capacity method and characteristic curve method simplifies selected process,improves consistency of battery module. Even though discharging at 240 A, variance of cell voltage was controlled in 20 mV.
