Method and apparatus for managing charge/discharge current of on-vehicle battery to control on-vehicle generator in consideration of offset of charge/discharge current
First Claim
1. 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.

Abstract
An apparatus is provided to manage a charge/discharge current of an on-vehicle battery. The apparatus comprises a detecting unit detecting an actual amount of the charge/discharge current and a receiving unit receiving information indicating generating operations of an on-vehicle generator. The apparatus also comprises a control unit controlling the generating operations of the generator so that the charge/discharge current keeps a given value specified, on the basis of the detected actual the charge/discharge current and the received information. The apparatus also comprises determining and setting units. The determining unit determines whether a voltage of the battery satisfies a given condition for the voltage, by monitoring the voltage in a state where the generating operation of the generator is controlled. The setting unit sets, as an amount of offset of the charge/discharge current, a charge/discharge current detected when it is determined that the voltage of the battery satisfies the given condition.

8. A method for managing a charge/discharge current of a battery mounted on a vehicle, comprising steps of:
-
detecting an actual amount of the charge/discharge current; receiving information indicative of an generating operation of a generator mounted on the vehicle and an excitation current supplied to the generator; controlling 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; determining 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; and setting, as an amount of offset of the charge/discharge current, a charge/discharge current detected when it is determined 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.
