摘要
This method for restoring battery capacity is provided with an oxygen-generating/exhausting step for charging a nickel-metal-hydride storage battery, causing the generation of oxygen gas in a positive electrode, opening a safety valve device, and discharging at least a portion of the oxygen gas through the safety valve device to the outside of the battery. The battery temperature when starting the step is in the range of −30 to 10° C. and the SOC is in the range of (30-Ta) to 100%, or the battery temperature (Ta) is in the range of 10 to 50° C. and the SOC is in the range of 20-100%.
