PROBLEM TO BE SOLVED: To provide a charge discharge controller capable of prolonging the life of an on-vehicle battery.SOLUTION: A charge discharge controller 10 controls charge and discharge of a battery 31, installed in a vehicle 30, so that the charging rate does not exceed an upper limit charging rate, between a dwelling house 20 including a load 21 and the vehicle 30. An information acquiring section 13 for acquiring the charging rate of the battery 31, a storage section 14 for storing the lowest charging rate, i.e., the lowest value of charging rate of the battery 31 acquired by the information acquiring section 13 when the battery 31 is charged up to the upper limit charging rate, and an upper limit charging rate changing section 15 for decreasing the upper limit charging rate when the lowest value of charging rate stored in the storage section 14 does not reach a discharge lower limit threshold, otherwise increasing the upper limit charging rate are provided.SELECTED DRAWING: Figure 1

    【課題】車載バッテリの寿命延伸を図ることができる充放電制御装置を提供する。【解決手段】充放電制御装置10は負荷21を含む住宅20と車両30との間において車両30に搭載されたバッテリ31の充電率が上限充電率を超えないようにバッテリ31の充放電を制御する。バッテリ31の充電率を取得する情報取得部13と、バッテリ31が上限充電率まで充電されるときの情報取得部13によるバッテリ31の充電率の最低値である最低充電率を記憶する記憶部14と、記憶部14に記憶された最低充電率が放電下限閾値に達していない場合に、上限充電率を低下させ、記憶部14に記憶された最低充電率が放電下限閾値に達している場合に、上限充電率を上昇させる上限充電率変更部15と、が備えられている。【選択図】図1
