Claim Text:
1. A battery control system comprising: a temperature measurement unit that measures temperatures of two or more battery units of a plurality of battery units which are connected in series to each other; a voltage measurement unit that measures voltages of the battery units; an electrification detection unit that detects electrification of the battery units; and a battery control unit that controls charge and discharge of the battery units, wherein the battery control unit, specifies a lowest temperature unit in which the temperature is lowest and a highest temperature unit in which the temperature is highest, on the basis of the temperatures measured by the temperature measurement unit, during the electrification of the battery units, further performs balance control for reducing a difference between the voltages of at least two battery units, on the basis of the voltages measured by the voltage measurement unit, when a first temperature condition in which a temperature difference between the highest temperature unit and the lowest temperature unit is equal to or greater than a reference value is not satisfied, and does not perform the balance control when the temperature difference satisfies the first temperature condition.
