Identifying and amerliorating a deteriorating condition for battery networks in-situ
A temperature is measured for each terminal of the battery unit. The magnitude and sign of a temperature differential is calculated from the temperatures. The temperature differential is then correlated to a deteriorating condition of the battery unit.
