Abstract:
Managing of battery pack cell capacity is provided. The managing includes monitoring temperature of one or more cells within the battery pack, and based on temperature of a cell of the one or more cells being at or below a low temperature threshold, initiating discharging of cells with the battery pack at a specified discharge power level to heat the cells within the battery pack. The managing also includes, based on temperature of a cell of the one or more cells rising to or above an upper temperature threshold after initiating discharging of the cells within the battery pack, discontinuing the discharging of cells within the battery pack.
