Batterieladesystem für Motorgenerator.

摘要

A battery charging system for a motor-generator, having a generator (4) for charging a battery (5), and an engine (2) for driving the generator, comprises a generator speed sensor (14) for detecting a generator speed of the generator; and an engine speed control circuit (36) for controlling an engine speed of the engine in the manner that the generator speed is set to a predetermined speed. The system can improve a charged efficiency and a long-life battery by charging the battery (5) to control a speed of the generator so as to perform a feedback control of the engine without keeping the engine speed at a constant speed, and by adaptively controlling the battery (5) by detecting gases occurring in the battery (5), namely, a gassing.
