CHARGE CONTROLLER OF BATTERY

摘要

PROBLEM TO BE SOLVED: To reduce the electric loss of an engine over the entire region from low rotation region to high rotation region.SOLUTION: A charge controller of a battery for charging a battery B by rectifying the output from an engine-driven AC generator 1 can switch between a short system for returning a power generation current back to the AC generator when the battery voltage reached a predetermined voltage, and an open system for interrupting the AC generator and the battery when the battery voltage reached a predetermined voltage. A control circuit 1 switches to the open system when the engine speed Nis less than a threshold N, otherwise switches to the short system.
