Power generation control apparatus for motorcar power distributor

Abstract

A power generation control apparatus to be used for a motorcar power distributor can effectively prevent any excessive charging current from flowing into the battery and consequently protect the battery against degradation. Additionally, it can minimize fluctuations in the supply voltage and functional failures in the loads of the electric equipment of the motorcar. The power generation control apparatus to be used for a motorcar power distributor comprises an alternator for generating an alternating current to be subjected to full-wave rectification by means of a rectifier to produce a direct current, said alternator being connected to the power supply route from the battery by way of an alternator supply line at a point immediately upstream relative to the branch point for branching the power supply so that the battery may be charged with power generated by the alternator and the loads may be fed respectively with the branched power supply. A power supply control means determines the relationship between the current detected by a load feeding current sensor and the current detected by a generated current sensor by comparing their intensities and controlling the rate of power generation of said alternator according to the determined relationship.
