PROBLEM TO BE SOLVED: To control a rechargeable battery loaded on a vehicle.SOLUTION: A vehicle power supply 1 controls a connection state of a first switch 11 and a second switch 12 connected to a dynamo 6, a lead battery 3 and a capacitor 5, according to a vehicle state. This enables smooth initiation at the first initiation of an engine because of electric conduction from the lead battery 3 to a starter 7. Further, because of electric conduction from the capacitor 5 to the starter 7 at a restart of the engine from a temporary stop state, a discharge of the lead battery 3 is suppressed so that deterioration can be prevented.SELECTED DRAWING: Figure 2 |
