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.

Abstract: A method for controlling the charging of multiple electric vehicles operating in a geographic area may include inputting a tariff schedule into a control system. The tariff schedule may identify the cost of energy at different times in the geographic area. The method may also include receiving data from the multiple electric vehicles. The data may include at least the state of charge of the vehicle. The method may further include sending instructions to at least one vehicle of the multiple electric vehicles. The instructions may include directives on charging based at least on the tariff schedule and the received data.
