Open the CIPO recordAbstract From the Canadian patent
An automotive charging apparatus employs a high voltage load such as a deicing means for deicing a windshield of the automobile in the line which connects a battery with an alternator. The automotive charging apparatus also employs a switch in parallel with the high voltage load so that an output voltage is supplied both to the high voltage load and to the battery when the switch member is opened and the output voltage is supplied only to the battery when the switch member is closed. The output voltage of the alternator changes to the higher level when the switch member is opened in order to maintain the battery voltage within the range of the predetermined value.
