Abstract
A method of recycling a battery pack includes first to third steps. The first step is a step of estimating an amount of generation of NiOH in a positive electrode of the battery pack based on a voltage value and a temperature of the battery pack. The second step is a step of recycling the battery pack for a high-capacity application when the estimated amount of generation is equal to or smaller than a prescribed reference amount. The third step is a step of recycling the battery pack for a high input-and-output application when the estimated amount of generation is greater than the reference amount and not greater than a reference amount.
