Power-supply-apparatus in a vehicle

Apparatus for charging a battery especially a battery in a motor

Disclosed is a device for and a method of applying output voltage from a power generator to a heating resistor in a motor vehicle. During the standstill condition of the vehicle the heating resistor is connected directly to the generator and a power supply network connected parallel to the terminals of a battery, is disconnected from the generator. The output voltage of the generator is regulated to increased values to achieve a higher efficiency in the heating resistor. During the travel of the motor vehicle, the heating resistor is connected in series with the power supply network and a regulated voltage from the power generator is applied across the series connection. The output voltage is regulated such that a nominal voltage is maintained at the power supply network. The switchover between the standstill and running operational conditions is provided by two switching devices which are controlled by a control device in dependency on operational conditions of the motor vehicle.
