【摘要】 对不同荷电量MH-Ni蓄电池进行储存试验,结果表明:长期储存的电池以荷电量20%左右对电池储存性能有利;对电池进行过放电试验表明,过放电短期内对电池容量没有影响,但会使电池内阻增大;对电池进行浅充放和全充放对比试验证明,经过长期浅充放,电池将发生不可逆容量衰减。以上试验有助于更进一步了解MH-Ni蓄电池的性能。更多还原

【Abstract】 The storage tests of Ni-MH cell with different charge states were investigated. The test results show that 20% SOC will be good for the cell to be stored for a long time. The overdischarge test was carried out. It showed that overdischarge had little effect on battery’s capacity within a short period, but may increase the internal resistance. The shallow charge and discharge test and fully charge and discharge test were compared. It indicated that unreversible capacity decreased happened after long term shallow charge and discharge. All the tests were helpful to understand the Ni-MH cell performance furtherly.更多还原
