Title (EN) POWER SUPPLY SYSTEM
(FR) SYSTÈME D'ALIMENTATION ÉLECTRIQUE
(JA) 電力供給システム
Abstract:
(EN) The present invention achieves reductions in the cost and size of a power supply system. This power supply system 1 is provided with a power supply mechanism 10, an electric load 11, a power transmission line 12, and a power storage pack 13. The power supply mechanism 10 supplies DC power. The electric load 11 is connected to the power supply mechanism 10. The power transmission line 12 connects the power supply mechanism 10 and the electric load 11. The power storage pack 13 is connected to the power transmission line 12. The charge/discharge curve of the power storage pack 13 has a step that passes through the rated voltage of the power supply mechanism 10. The average discharge voltage further to the low SOC side than the start point of the step in the charge/discharge curve of the power storage pack 13 is -20% or more in relation to the rated voltage. The average charging voltage further to the high SOC side than the end point of the step in the charge/discharge curve of the power storage pack 13 is +20% or less in relation to the rated voltage.
(FR) La présente invention permet de réaliser des réductions du coût et de la taille d'un système d'alimentation électrique. Ce système d'alimentation électrique (1) est pourvu d'un mécanisme d'alimentation électrique (10), d'une charge électrique (11), d'une ligne de transport d'électricité (12) et d'un bloc de stockage d'électricité (13). Le mécanisme d'alimentation électrique (10) fournit du courant continu. La charge électrique (11) est connectée au mécanisme d'alimentation électrique (10). La ligne de transport d'électricité (12) connecte le mécanisme d'alimentation électrique (10) et la charge électrique (11). Le bloc de stockage d'électricité (13) est connecté à la ligne de transport d'électricité (12). La courbe de charge/décharge du bloc de stockage d'électricité (13) présente un échelon qui passe à travers la tension nominale du mécanisme d'alimentation électrique (10). La tension de décharge moyenne davantage vers le côté état de charge (SOC) faible que le point de départ de l'échelon dans la courbe de charge/décharge du bloc de stockage d'électricité (13) est supérieure ou égale à -20 % par rapport à la tension nominale. La tension de charge moyenne davantage vers le côté SOC élevé que le point final de l'échelon dans la courbe de charge/décharge du bloc de stockage d'électricité (13) est inférieure ou égale à +20 % par rapport à la tension nominale.
(JA) 電力供給システムの低価格化及び小型化を図る。 電力供給システム1は、電力供給機構10と、電気負荷11と、送電線12と、蓄電パック13とを備える。電力供給機構10は、直流電力を供給する。電気負荷11は、電力供給機構10に接続されている。送電線12は、電力供給機構10と電気負荷11とを接続している。蓄電パック13は、送電線12に接続されている。蓄電パック13の充放電曲線は、電力供給機構10の定格電圧を通過する段差を有している。蓄電パック13の充放電曲線が有する段差の開始点よりも低SOC側における平均放電電圧が定格電圧の-20%以上である。蓄電パック13の充放電曲線が有する段差の終了点よりも高SOC側における平均充電電圧が定格電圧の+20%以下である。
