Patent ID: 7609035

Claim:
A power generation control device for controlling a generator for a movable body which stores electric power in a battery, comprising: an electric load monitoring unit for monitoring a quantity of load electricity consumed by a first electric load; a driving state judging unit for judging whether the movable body is in an accelerating state or not; and a power generation control unit for controlling power generation by the generator based on a battery suppliable current which can be taken out of the battery, a quantity of electricity generated by the generator, an essential supply current consumed by a second electric load to which electric power must be supplied, and a load working current consumed by the first electric load which is detected by the electric load monitoring unit, when it is judged that the movable body is in the accelerating state by the driving state judging unit, wherein the power generation control unit controls power generation by the generator when it is judged that a first power generation control condition that a value obtained by subtracting the essential supply current and the load working current from the battery suppliable current is a prescribed value (≧0) or more has been satisfied.
