Abstract

Official abstract text for this publication.

In a vehicle has a generator and a secondary battery, when a power storage ratio of the secondary battery becomes less than or equal to a first threshold value, until the power storage ratio becomes a second threshold value, which is greater than the first threshold value, a charging control apparatus sets an upper limit of power generation voltage of the generator other than during deceleration of the vehicle, to be higher than an upper limit of the power generation voltage other than during deceleration of the vehicle when the power storage ratio is greater than the second threshold value. The charging control apparatus is provided with: a changing device configured to change the second threshold value so that the second threshold value approaches the first threshold value when a discharge-charge tendency of the secondary battery based on past data associated with the power storage ratio is a charge tendency.

First claim

Opening claim text (preview).

What is claimed is: 1 . A charging control apparatus mounted on a vehicle comprising a generator and a secondary battery that can store electric power generated by the generator, said charging control apparatus being configured in such a manner that when a power storage ratio, which is a ratio of a power storage amount of the secondary battery to full capacity, becomes less than or equal to a first threshold value, until the power storage ratio becomes a second threshold value, which is greater than the first threshold value, an upper limit of power generation voltage of the generator other than during deceleration of the vehicle is set to be higher than an upper limit of the power generation voltage other than during deceleration of the vehicle when the power storage ratio is greater than the second threshold value, said charging control apparatus comprising: a changing device configured to change the second threshold value so that the second threshold value approaches the first threshold value when a discharge-charge tendency of the secondary battery based on past data associated with the power storage ratio is a charge tendency. 2 . The charging control apparatus according to claim 1 , wherein said changing device changes the second threshold value so that the second threshold value deviates from the first threshold value when the discharge-charge tendency is a discharge tendency.
