PROBLEM TO BE SOLVED: To prevent extraneous charging of a battery in cases where an auxiliary-equipment current is small even with a high stop time ratio, or where a stop time ratio is low even with a large auxiliary-equipment current.SOLUTION: A battery charge control apparatus, incorporated in a vehicle that includes an engine, a battery rechargeable with a power generation amount of a generator driven by power of the engine, and an auxiliary equipment set capable of operating on the battery, includes: a stop time ratio obtainment part for obtaining a stop time ratio in a given period of the vehicle; an auxiliary-equipment amperage obtainment part for obtaining an amperage in the auxiliary equipment set as an auxiliary-equipment amperage; and a charging-target value setup part for setting a charging-target value of the battery on the basis of the stop time ratio and auxiliary-equipment amperage. The charging-target value setup part sets the charging-target value on the basis of map data in which a charging-target value is assigned to each respective position on a two-dimensional coordinate space that specifies a graph representing a relation where the stop time ratio is inverse proportion to the auxiliary-equipment amperage.

    【課題】停車時間率が高くても補機電流量が小さい場合や、補機電流量が大きくても停車時間率が低い場合に、バッテリを無駄に充電させないようにする。【解決手段】エンジンと、エンジンの動力によって駆動される発電機の発電量によって充電可能なバッテリと、前記バッテリを用いて動作し得る補機類と、を有する車両に搭載されるバッテリ充電制御装置である。このバッテリ充電制御装置は;前記車両の所定期間における停車時間率を取得する停車時間率取得部と;前記補機類の電流量を補機電流量として取得する補機電流量取得部と;前記停車時間率と前記補機電流量に基づいて、前記バッテリの充電目標値を設定する充電目標値設定部と;を備える。前記充電目標値設定部は、前記停車時間率と前記補機電流量とが反比例の関係にあるグラフを規定する2次元座標空間上の各位置に前記充電目標値を割り当てたマップデータに基づいて、前記充電目標値の設定を行う。【選択図】図3
