Abstract
Abstract A charging control system for a vehicle (11) includes a charge control microcomputer (6) for determining the most suitable reference voltage for the charging system voltage regulator (3) based on various input data from the charging system and an engine control microcomputer (8). The device also detects faults in the charging system by processing the charging system data inputs and displays the detection result on a display unit (7).
