摘要
The vehicle battery charging system of the main patent includes a fault evaluating device (40) which can be in integrated circuit form. This forms part of a system for indicating faults in the generator or mains supply etc., as well as the charge controller. The generator section (10) includes a rectifier (13) with positive and negative diodes (13,13a) and a half bridge (14) with exciter diodes. The fault evaluator is in the charge controller (16) with voltage and load regulator sections (17,18). The faults detected include too high or low generator output voltages, interruption of its excitation, and of the sensing line (46) connected to the positive connection point (B+) for the batteries, also interruption of the charging line (37), and of the generator. Also faults in the region of the diodes (13) and the phase windings (12) of the generator are indicated. PS.
