Abstract
A method for balancing energy in an energy storage system of an electric vehicle includes detecting a first voltage of a first energy storage unit (ESU) and a second voltage of a second energy storage unit of the energy storage system, and determining a discharge time corresponding to the detected second voltage. The method may also include discharging energy from the first energy storage unit, while not discharging energy from the second energy storage unit, for a duration of the determined discharge time.
