Control apparatus and method for vehicle equipped power supply having battery deterioration diagnostic feature
First Claim
1. A control apparatus for a power supply equipped in an automotive vehicle, the vehicle including an engine, a starter to start the engine, a battery to reserve an electrical power supplied to the starter, and a generator driven by the engine to generate the electrical power to charge the battery, the control apparatus comprising:
- a battery voltage detecting section that detects a terminal voltage of the battery in a form of a battery voltage;
a charge current detecting section that detects a charge current flowing into the battery from the generator; and
a deterioration determining section configured to determine a degree of deterioration of the battery on the basis of a battery voltage detected after the power supply is turned on and before a start of operation of the generator and on the basis of a charge current detected after the start of operation of the generator.

Abstract
In control apparatus and method for a power supply equipped in an automotive vehicle, the vehicle includes an engine, a starter to start the engine, a battery to reserve the electrical power supplied to the starter, and a generator driven by means of the engine to generate the electrical power to charge the battery, a terminal voltage of the battery is detected in a form of a battery voltage, a charge current flowing into the battery by means of the generator is detected, and a degree of deterioration of the battery is determined on the basis of at least one of the battery voltage detected after the power supply is turned on and before a start of operation of the generator and the charge current detected after the start of operation of the generator.
