Abstract
A battery control circuit for balancing a battery includes a voltage detector, a controller, a balancing device, and a switch. The voltage detector is configured to detect a voltage difference of the battery so as to generate a detecting signal. The controller is configured to generate a control signal according to the detecting signal. The switch is coupled between the battery and the balancing device, and is opened or closed according to the control signal, wherein if the voltage difference is greater than a threshold value, the switch is closed and the balancing device draws a load current from the battery, and if the voltage difference is smaller than or equal to the threshold value, the switch is opened and the balancing device is not capable of drawing any current.
