A storage battery 5 is pulse- charged by connecting it via a voltage regulator 4 to a generator 1 which is driven by the vehicle engine 6 and which is operated in a fully excited state so that it has a non-regulated output voltage which increases with increase in its driver speed. The pulse-charging duty ratio can be charged when a high discharge current is measured. The duty ratio can also be varied in response to a timer or to the state of charge of the battery 5. A constant voltage is supplied by regulator 4 to a buffer battery 2 and loads 3. When the generator 1 is idling or not operating, battery 5 is connected to battery 2 by a voltage - or speed - dependent switch 7. <IMAGE> |
