Abstract
The output voltage of an engine-driven generator is varied in accordance with engine vacuum in a manner to increase the charging rate during deceleration of the vehicle and to decrease the charging rate during acceleration of the vehicle. The charging current developed in the generator is alternately applied to one or the other of two storage batteries while the other storage battery is connected to supply power to the various electrical loads of the vehicle. A switching circuit responsive to the terminal voltage of the battery connected to supply power to the loads operates to exchange the battery connections when the voltage supplied to the loads decreases below a reference value so that the depleted battery is connected to be charged by the generator and the charged battery is connected to supply power to the loads.
