<p>PURPOSE:To controllably prevent auxiliaries mounted on a vehicle from an evil influence of a battery having a voltage drop due to the consumption of large electric power when a dynamo-electric machine mounted on a turbine shaft of a turbocharger is motor driven to increase supercharging pressure. CONSTITUTION:A relay 1 for opening and closing a circuit between a battery 2 and generator 3, a charging current limiting resistor R and a relay 2 connected in parallel to the resistor R are connected as shown in the drawing. The relay 1 is turned off when a dynamo-electric machine 1 is motor driven, and current is supplied from the generator 3 to auxiliaries 4 to prevent the battery 2 from the reduction of terminal voltage. In charging the battery 2 having a charge amount reduced due to the motor drive, charging current from the generator 3 is limited through the resistor R to lessen a drop in generating voltage. When the battery is recovered to a predetermined voltage value, the relay 2 is closed to short the resistor R.</p> |
