Patent ID: 7750602

Claim:
An apparatus for managing a charge/discharge current of a battery mounted on a vehicle, comprising: a detecting unit that detects an actual amount of the charge/discharge current; a receiving unit that receives information indicative of a generating operation of a generator mounted on the vehicle and an excitation current supplied to the generator; a control unit that controls the generating operation of the generator so that the charge/discharge current of the battery keeps a given value specified for the charge/discharge current, on the basis of both the detected actual amount of the charge/discharge current and the received information indicative of the generating operation of the generator; a determining unit that determines whether or not the number of revolutions of the generator is within a given range of revolutions and whether or not the excitation current is within a given range of the excitation current in a state where the generating operation of the generator is controlled by the control unit; and a setting unit that sets, as an amount of offset of the charge/discharge current, a charge/discharge current detected by the detecting unit when it is determined by the determining unit that the number of revolutions of the generator is within the given range of revolutions and the excitation current is within the given range of the excitation current.
