Attorney, Agent or FirmInternational ClassesH02J 7/16 (20060101)H02J 7/14 (20060101) Foreign Application Priority Data1982-05-18 JPAbstractA charge control microcomputer is provided for a vehicle charging system to control the reference voltage employed by the voltage regulator so that a suitable battery charging voltage is generated at all times. The microcomputer processes charging system data such as the battery output voltage, the generator output current, etc., and at least one engine parameter from an engine control microcomputer to derive the most suitable reference voltage for the voltage regulator. | |
