A cell equalization system includes: a battery including a plurality of chargeable cells connected in series and mounted on a vehicle; a battery ECU configured to control the battery; an equalization circuit configured to perform equalization of remaining capacity variation of the plurality of cells; and an equalization control unit configured to control the equalization circuit. The battery ECU is configured to calculate the remaining capacity variation at startup of ECU in which the battery ECU changes from a sleep state to a startup state. The cell equalization system is configured to execute first equalization processing for performing the equalization when the battery ECU is in the startup state, and second equalization processing for performing the equalization when the battery ECU is in the sleep state.
