PROBLEM TO BE SOLVED: To provide a charger that can reduce its size as well as compensate power insufficiency even if power supply from a commercial power supply is insufficient.SOLUTION: When electric power determination means 130 determines that total power necessary for charging a plurality of vehicles 3 that are connected to a charger 1 to be charged is larger than the commercial power that can be supplied from a commercial power supply 2, discharged power from at least one of the vehicles 3 is inputted to power control means 100 by a control of charge/discharge control means 130. Then, the discharged power inputted into the power control means, together with the commercial power converted to a DC power by power conversion means 140 and inputted into the power control means, is outputted to at least one of the other vehicles. 【課題】商用電源からの供給電力が不足しても、電力の不足を補いつつ装置の小型化が可能な充電装置を提供する。【解決手段】充電装置１に接続して充電しようとする複数の車両３の充電に必要な電力の合計が商用電源２から供給可能な商用電力より大きいと電力判定手段１３０により判断された場合に、充放電制御手段１３０の制御により、少なくとも一つの車両３からの放電電力を電力制御手段１００に入力させる。そして、電力制御手段に入力させた放電電力を、電力変換手段１４０により直流電力に変換させ電力制御手段に入力させた商用電力とともに他の少なくとも一つの車両に出力させる。【選択図】図１
