Abstract:
Embodiments of the disclosure may include a method of managing a state of charge of a battery having a plurality of battery cells. The method may include calculating an individual state of charge for each battery cell, calculating an average state of charge for the battery cells, defining a minimum and a maximum average state of charge threshold, and calculating an overall state of charge for the battery such that when the average state of charge is below the minimum threshold, the overall state of charge is calculated based on the state of charge of a subset of battery cells having the lowest state of charge, and when the average state of charge is above the maximum threshold, the overall state of charge is calculated based on the state of charge of a subset of battery cells having the highest state of charge.
