Abstract
A main power source is, for example, an ordinary Pb battery. At the time of starting an engine, the main power source supplies power to a starter. The main power source is given a higher priority than an auxiliary power source to supply power to ordinary loads. The auxiliary power source is a high performance battery (e.g., Li ion battery), which has superior charge acceptance capability and better state detectability over the main power source. The auxiliary power source stores regenerative power, which is generated by a generator at the time of deceleration of a vehicle, and is used as a redundant power source for the main power source. The main power source and the auxiliary power source are connected to each other through a supply circuit, which has a DC/DC converter, and a second supply circuit, which has a switch.
