本実施形態において、主制御ボード1430は、1以上の充電ユニット420の少なくとも2つに配されたAC/DC充電器1460を制御する。主制御ボード1430は、1以上の充電ユニット420のそれぞれに配されたAC/DC充電器1460を制御してよい。例えば、主制御ボード1430は、制御対象となるAC/DC充電器1460のそれぞれが配された充電ユニット420のセンス部1486から、制御対象となるAC/DC充電器1460のそれぞれと電気的に接続されたバッテリ20のそれぞれの蓄電量に関する情報を取得する。主制御ボード1430は、上記のAC/DC充電器1460のそれぞれを制御して、上記のバッテリ20のそれぞれを充電させる。
本実施形態において、主制御ボード1430は、1以上の充電ユニット420の少なくとも2つに配された温度調節部1482を制御する。主制御ボード1430は、1以上の充電ユニット420のそれぞれに配された温度調節部1482のそれぞれを制御してもよい。

図16に示されるとおり、時刻tpcよりも前の時刻において、バッテリ22及びバッテリ24の温度はTfa[℃]である。図2に関連して説明されたとおり、時刻t0においてバッテリ22の充電が開始される。そこで、本実施形態においては、時刻t0よりも前の時刻tpcにおいて、バッテリ22の冷却が開始される。これにより、時刻tpcから時刻t0までの期間において、バッテリ22の温度が低下する。その結果、時刻t0において、バッテリ22の温度は、Tpc[℃]になる。なお、Tpc<Tfaである。
時刻tpcは、バッテリ22及びバッテリ24の充電完了時において、バッテリ22及びバッテリ24の温度が略同一となるように決定される。例えば、時刻tpcは、蓄電量の多いバッテリ24の充電が開始される時刻t1において、バッテリ22及びバッテリ24の温度が略同一となるように決定される。主制御ボード1430は、時刻t0におけるバッテリ22の温度がTpcとなるように、バッテリ22の冷却態様を決定してもよい。冷却態様としては、冷却方式、冷却強度、冷却期間の長さ、冷却開始時刻、冷却終了時刻などが例示される。
本実施形態においては、時刻tpcにおいて、バッテリ22及びバッテリ24の蓄電量が異なり、バッテリ22及びバッテリ24の温度が略同一である場合を例として、バッテリ22及びバッテリ24の温度を調整する手順の一例が説明された。しかしながら、バッテリ22及びバッテリ24の温度を調整する手順は、本実施形態に限定されない。他の実施形態において、時刻tpcにおいて、バッテリ22及びバッテリ24の蓄電量が略同一であり、バッテリ22及びバッテリ24の温度が異なる場合に、温度が高い方のバッテリの冷却強度が、温度が低い方のバッテリの冷却強度よりも大きくなるように、バッテリ22及びバッテリ24の冷却が制御される。例えば、時刻tpcにおいて、温度が低い方のバッテリの冷却は停止したまま、温度が高い方のバッテリの冷却が開始される。
本実施形態においては、バッテリ22の冷却開始時刻と、バッテリ22の充電開始時刻とを調整することで、バッテリ22及びバッテリ24の充電完了時におけるバッテリ22及びバッテリ24の温度が調整される場合を例として、バッテリ22及びバッテリ24の温度調整手法の一例が説明された。しかしながら、バッテリ22及びバッテリ24の温度調整手法は、本実施形態に限定されない。
