PURPOSE:To improve safety without deteriorating cold drivability by connecting a rotation speed switch, a temperature switch, a car speed switch and an electric load member in series in a charging circuit which connects power generator to a storage cell. CONSTITUTION:A rotation speed switch 4 which opens and closes according to the engine rotation speed, a temperature switch 5 which opens and closes according to the temperature of the engine system, a car speed switch 6 which opens and closes according to the car speed and a heater 7 acting as an electric load member here are connected in series on the way of a charging circuit which connects an alternator 2 driven by an engine 1 to a storage cell 3. When warming up operation is required, the said switches 4-6 are closed respectively to electrify the heater 7 and the energy of the engine under warming-up is converted into electric energy and thermal energy and utilized effectively, and warming-up operation is maintained. Then, safety and silence are improved without deteriorating cold drivability and warming-up characteristic. |
