Abstract
A battery management system includes a constant voltage DC/DC converter, an integrated circuit, and a regulator. The converter receives a first voltage from a plurality of battery cells and generates a first output voltage at a substantially constant level. The integrated circuit measures voltages of the cells and balances the cells. The regulator converts the first output voltage to a second output voltage. The first output voltage is supplied as a power supply voltage of the integrated circuit.
