To increase battery temperature efficiently while traveling under cryogenic temperature environment.SOLUTION: A control arrangement 10 of a vehicle includes an acquisition part 11 for acquiring battery temperature Tb, a calculation part 12 for calculating the charging rate SOC and the heat release Q, a determination part 13 for determining success of start conditions including the fact that the battery temperature Tb is less than a prescribed temperature Tx, a mode selection part 16 for selecting discharge mode until the charging rate SOC goes below a lower limit threshold level SOCb if it goes above a prescribed upper limit threshold level SOCu when the start conditions are satisfied, and for selecting charge mode until the charging rate SOC goes above an upper limit threshold level SOCu if it goes below a lower limit threshold level SOCb, and a setting part 17 for setting the target value Wj of power generation amount of a generator at a first target power generation amount W1 higher than a normal target power generation amount W0 during charge mode selection, and setting the target value Wj at a second target power generation amount W2 lower than the normal target power generation amount W0 during discharge mode selection. The setting part 17 sets at least one of the first and second target power generation amounts W1, W2 on the basis of the heat release.SELECTED DRAWING: Figure 2
【課題】極低温環境下での走行時に、バッテリを効率的に昇温する。【解決手段】車両の制御装置10は、バッテリ温度Tbを取得する取得部11と、充電率SOC及び放熱量Qを算出する算出部12と、バッテリ温度Tbが所定温度Tx未満であることを含む開始条件の成否を判定する判定部13と、開始条件成立時に、充電率SOCが所定の上限閾値SOCu以上なら下限閾値SOCb以下になるまで放電モードを選択する一方で、充電率SOCが下限閾値SOCb以下なら充電率SOCが上限閾値SOCu以上になるまで充電モードを選択するモード選択部16と、充電モード選択中に、ジェネレータの発電量の目標値Wjを、通常目標発電量W0よりも高い第一目標発電量W1に設定し、放電モード選択中に、目標値Wjを通常目標発電量W0以下の第二目標発電量W2に設定する設定部17と、を備える。設定部17は、第一目標発電量W1及び第二目標発電量W2の少なくとも一方を放熱量Qに基づいて設定する。【選択図】図2
