Abstract

The vehicle battery controller includes a controller for interconnecting an auxiliary battery to a main battery for engine starting or charging. If the auxiliary battery voltage is lower than a first threshold before engine starting its subsequent use is inhibited. If the main battery voltage exceeds the auxiliary battery voltage by more than a predetermined margin, the auxiliary battery is not used for engine starting. When the engine is running and the charging system is operating, the auxiliary battery is disconnected when the common voltage is below a second threshold.
