Abstract：The operation temperature is an effective factor on charge - discharge performance of large capacity Ni-MH battery. Based on the characteristic of Ni-MH battery used in EVs, the cause and the adopted measure for poor performance of battery at high and low temperature were described. The effects of temperature on discharge capacity and charge efficiency were analyzed. The effects of temperature on self-dischrge and cycle life were tested, this experimental data were useful for Ni-MH battery application to EV.
