Title (EN) COMBINED POWER STORAGE SYSTEM
(FR) SYSTÈME COMBINÉ D’ACCUMULATION DE PUISSANCE
(JA) 複合蓄電システム
Abstract:
(EN) A combined power storage system having a power-type battery and a capacity-type battery, wherein: the power-type battery and the capacity-type battery are directly connected in parallel to each other; the power-type battery and the capacity-type battery are connected to a motor via a power converter; the resistance value of wiring from the power-type battery to the power converter is smaller than the resistance value of wiring from the capacity-type battery to the converter; and, e.g., the length of the wiring from the power-type battery to the power converter is less than the length of the wiring from the capacity-type battery to the power converter. This makes it possible to distribute the discharge and charge currents generated during travel of an electric automobile to the power-type battery, therefore making it possible to inhibit degradation of the capacity-type battery.
(FR) L’invention concerne un système combiné d’accumulation de puissance ayant une batterie de type à puissance et une batterie de type à capacité : la batterie de type à puissance et la batterie de type à capacité étant directement connectées en parallèle entre elles ; la batterie de type à puissance et la batterie de type à capacité étant connectées à un moteur par le biais d’un convertisseur de puissance ; la valeur de résistance de câblage entre la batterie de type à puissance et le convertisseur de puissance étant inférieure à la valeur de résistance de câblage entre la batterie de type à capacité et le convertisseur ; et, par ex., la longueur du câblage entre la batterie de type à puissance et le convertisseur de puissance étant inférieure à la longueur du câblage entre la batterie de type à capacité et le convertisseur de puissance. Cela permet de répartir les courants de charge et de décharge générés pendant le trajet d’une automobile électrique vers la batterie de type à puissance, permettant ainsi d’inhiber la dégradation de la batterie de type à capacité.
(JA) パワー型電池と容量型電池とを有する複合蓄電システムであって、パワー型電池と容量型電池とが互いに直に並列接続され、パワー型電池と容量型電池とが電力変換器を介してモータに接続され、パワー型電池から電力変換器までの配線の抵抗値は、容量型電池から変換器までの配線の抵抗値よりも小さく、例えば、パワー型電池から電力変換器までの配線の長さは、容量型電池から電力変換器までの配線の長さよりも短くする。これにより、電気自動車の走行時に発生する放電および充電の電流をパワー型電池に配分することができるため、容量型電池の劣化を抑制することができる。
