POWER GENERATION CONTROL DEVICE

摘要

PROBLEM TO BE SOLVED: To control the drive and stop of a power generator while taking fuel consumption performance into consideration.SOLUTION: A control unit for controlling an alternator which generates power by a driving force of an engine and charges a battery comprises a drive permission determination part for determining the drive and stop of the alternator on the basis of an engine efficiency and an SOC of the battery. The drive permission determination part is configured to determine the drive of the alternator when the SOC is smaller than a threshold SOC for driving which determines the drive of the alternator, and determines the stop of the alternator when the SOC is greater than a threshold SOC for stopping which determines the stop of the alternator. The threshold SOC for stopping is higher than the threshold SOC for driving as an engine efficiency is higher and power generation cost is lower.SELECTED DRAWING: Figure 18
