To provide a charger-discharger in which priority levels of discharging of a plurality of storage batteries can be set.SOLUTION: A charger-discharger 1 for an electric vehicle comprises: a reception part 111 which receives an indication for which of a battery 21 for power and a storage battery 31 capable of being discharged to supply electric power to a home-use load 8 is to be discharged preferentially; a discharging control part 114 which starts discharging the battery 21 for power when electric power supplied from a system power supply 7 to the home-use load 8 exceeds a set value of purchase electric power of a charger-discharger 1 for an electric vehicle; and a change part 115 which changes, once the reception part 111 receives the indication, the set value of purchase electric power of the charger-discharger 1 for the electric vehicle based upon the indication and the set value of purchase electric power of a charger-discharger 3 for the storage battery as a threshold of electric power supplied from the system power supply 7 starting discharging the storage battery 31 to the home-use load 8.SELECTED DRAWING: Figure 2
【課題】複数の蓄電池の放電の優先順位を設定することができる充放電器を得ること。【解決手段】電気自動車用充放電器1は、放電により家庭内負荷8への電力の供給が可能な動力用電池21および蓄電池31のうち、どちらの放電を優先させるかの指示を受け付ける受付部111と、系統電源7から家庭内負荷8へ供給される電力が電気自動車用充放電器1の買電電力の設定値を超えると動力用電池21の放電を開始させる放電制御部114と、受付部111が上記指示を受け付けると、上記指示と蓄電池31の放電が開始される系統電源7から家庭内負荷8へ供給される電力の閾値である蓄電池用充放電器3の買電電力の設定値とに基づいて電気自動車用充放電器1の買電電力の設定値を変更する変更部115とを備える。【選択図】図2
