To provide a power conditioner capable of creating a space in advance for a surplus power amount in a storage battery of a power storage device more reliably than before.SOLUTION: A power conditioner 10A is provided with a controller 50 including a surplus power amount prediction unit 54 and a grid-charge necessity determination unit 55. The surplus power amount prediction unit 54 predicts a surplus power amount being a difference between a generated power amount of a photovoltaic power generation device 80 and a power amount consumed by household loads 85. The grid-charge necessity determination unit 55 moves, when the surplus power amount is larger than a space power amount of a storage battery 81a that configures a power storage device 81, a power amount calculated by a formula "surplus power amount - space power amount of the storage battery 81a" from the storage battery 81a to a storage battery 83a that configures an electric vehicle 83 connected to an electric vehicle charging device 82, and further charges, when a state of charge of the storage battery 83a does not reach a predetermined target state of charge by the above moving, the storage battery 83a using power from a commercial power grid 84.SELECTED DRAWING: Figure 1
【課題】従来よりも確実に蓄電装置の蓄電池に余剰電力量分の空きを予めつくることが可能なパワーコンディショナを提供する。【解決手段】パワーコンディショナ10Aは、余剰電力量予測部54および系統充電要否判定部55を含む制御部50を備える。余剰電力量予測部54は、太陽光発電装置80の発電電力量と家庭負荷85の消費電力量との差である余剰電力量を予測する。系統充電要否判定部55は、余剰電力量が蓄電装置81を構成する蓄電池81aの空き電力量よりも多い場合は、蓄電池81aから電動車用充電装置82に接続された電動車83を構成する蓄電池83aに式“余剰電力量-蓄電池81aの空き電力量”で計算される量の電力を移動させ、さらに、上記移動により蓄電池83aの充電率が予め定めた目標充電率に達しない場合は、商用電力系統84からの電力を用いて蓄電池83aを充電させる。【選択図】図1
