To provide an electric vehicle power supply system which is simply formed.SOLUTION: An electric vehicle power supply system 1 includes: first terminals 111 and 211; second terminals 112 and 212; and conversion sections 12 and 22. The first terminals are electrically connected to power storage devices 14 provided in the formation of electric vehicles ETA and ETB and any of wires L. The second terminals are electrically connected to pull-through lines 31 and 32 together with a plurality of motors 41 and 42 in the formation, a self-power supply device 11, and an external power supply device 21. The conversion section takes in first power supplied from the plurality of electric motors and the external power supply device from the second terminals, generate DC voltage at the first terminals by regenerative operations of self-conversion sections, and charge the power storage device in a first operation state, and takes in second power supplied from the power storage device and any of wires from the first terminals, converts a part of second power into third power by power running operation of the self-conversion sections, outputs the third power from the second terminals, and converts the power in a second operation state.SELECTED DRAWING: Figure 1

    【課題】簡素に形成された電気車用電源システムを提供する。【解決手段】電気車用電源システム1は、第1端子111、211と、第2端子112、212と、変換部12、22とを持つ。第1端子は、電気車ETA、ETBの編成内に設けられている蓄電装置14と架線Lの何れかに電気的に接続される。第2端子は、編成内の複数の電動機41、42と自電源装置11と外部電源装置21とともに引き通し線31、32に電気的に接続される。変換部は、第1動作状態において、複数の電動機と外部電源装置から供給される第1電力を第2端子から取り込み、自変換部の回生運転によって第1端子に直流電圧を発生させて蓄電装置を充電し、第2動作状態において、蓄電装置と架線の何れかから供給される第2電力を第1端子から取り込み、自変換部の力行運転によって第2電力の一部を第3電力に変換して、第3電力を第2端子から出力して、電力を変換する。【選択図】図1
