The invention discloses a battery voltage balance control system and method, and relates to the technical field of battery management. A voltage balance control unit of the control system is respectively connected with a plurality of battery branches, a plurality of first contactors, a plurality of second contactors and a plurality of adjustable resistors; and acquiring the voltage of each battery branch, calculating the voltage difference value of any two battery branches, if a certain voltage difference value is not less than a preset voltage value, controlling the first contactor and the second contactor of the related battery branch to act, and adjusting the resistance value of the adjustable resistor of the related battery branch until all the voltage difference values are less than the preset voltage value. According to the control system provided by the embodiment of the invention, the voltage of the plurality of battery branches is obtained through the voltage balance control unit, the voltage of one battery branch is controlled by adjusting the resistance value of the adjustable resistor of the battery branch, and the voltage difference value of the battery branches is reduced, so that the battery branches are safely connected in parallel without generating large current impact; and the arc discharge phenomenon is avoided, so that the personnel safety is ensured.
