CHARGE VOLTAGE REGULATOR FOR BATTERY IN VEHICLE

摘要

A charge voltage regulator comprising a generator (26) interlockingly coupled with a running/driving internal combustion engine (2), a battery (28) connected to this generator (26) via a charge control circuit (27), and a starting motor (29) driven by the power from this battery (28). When the internal combustion engine (2) is started or accelerated, and later is found running at less than a specified rotation speed and running for less than a specified time after the starting or the accelerating, the charge control circuit (27) is controlled to reduce a charge voltage from the generator (26) to the battery (28) to below a normal-time reference charge voltage. Accordingly, the starting of an internal combustion engine or the acceleration of a vehicle by running an internal combustion engine can be quickened without wastefully reducing a vehicle-mounted battery charge amount.
