Title:
車両用バッテリ充電制御装置および車両用バッテリの充電制御方法
Document Type and Number:
Japanese Patent JP4756786
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To control the charging of a battery for preventing fuel efficiency from deteriorating, and to prevent a battery from going dead. SOLUTION: A microcomputer 16 detects whether traveling state of a vehicle is an acceleration state, an idling state, or a constant speed state, and if the state is decided, calculates an integrated value of a current flowing into/out of a battery 5 in that state, and determines a power generating voltage of a generator 3, so as to make the current integrated value zero. With such a constitution, in a traveling state which cannot be said to be advantageous from the fuel efficiency point of view, in comparison with a deceleration state, a power-generating voltage is elevated to charge the battery 5 positively only during a period, while the battery has the tendency of the discharge, so that the decline of a fuel efficiency can be avoided, while the battery going dead is prevented.
