PROBLEM TO BE SOLVED: To provide a power supply system capable of supplying power to an electric load from two power storage devices with appropriate load distribution.SOLUTION: The power supply system includes: a first power storage device 2; a second power storage device 3 having an output density higher than the first power storage device and a lower energy density; a power transmission circuit unit 11 configured to control power transmission between an electric load 100 and the first and second power storage devices according to a given control signal; and a control device 5 which controls the power transmission circuit unit. The control device acquires a request output from the electric load and a second residual capacity, which is the residual capacity of the second power storage device, and according to the request output and the second residual capacity, controls the power transmission circuit to change the load mode of the outputs of the first and second power storage devices in response to the request output according to a plurality of mode types classified according to the second residual capacity.SELECTED DRAWING: Figure 1
【課題】2つの蓄電装置から適切な負担配分で電気負荷に給電することを可能とする電力システムを提供する。【解決手段】電力供給システムは、第1蓄電装置2と、第1蓄電装置よりも出力密度が高く、エネルギー密度が低い第2蓄電装置3と、電気負荷100と第1蓄電装置と第2蓄電装置との間の電力伝送を、与えられる制御信号に応じて制御するように構成された電力伝送回路部11と、電力伝送回路部を制御する制御装置5とを備える。制御装置は、電気負荷の要求出力と、第2蓄電装置の残容量である第2残容量とを取得し、要求出力に対する第1蓄電装置及び第2蓄電装置の出力の負担形態を、第2残容量に応じて分類される複数種類の形態に変更するように、要求出力と第2残容量とに応じて電力伝送回路部を制御する。【選択図】図1
