ABSTRACT:
A control circuit for controlling the recharging of two batteries in a dual battery vehicle electrical system includes a charging circuit (20) for stepping up the voltage of a reserve battery (RES.), so that it can be applied to a starting battery (HPB), an alternative circuit path (18, 19) to allow charging of both batteries by the alternator (A) when the vehicle engine is running, and a controller (30) for switching the connection of the batteries through the charging circuit (20) and the alternative circuit path (18, 19) under various combinations of conditions.
