To provide an electric power system and an electric vehicle capable of continuing travel of a vehicle even when abnormality such as disconnection and earth fault is caused in an electric power supply passage to a motor from a power storage element.SOLUTION: In an electric power system 20 mounted on a vehicle 10, a control part can electrically conduct a first power supply passage 30A and a second power supply passage 30B by putting a first relay 22A and a second relay 22B in an ON state when abnormality of the first power supply passage 30A and the second power supply passage 30B is not detected by a detection part. When the abnormality of the first power supply passage 30A is detected by the detection part, electric conduction of the first power supply passage 30A is cut off by putting the first relay 22A in an OFF state, and when the abnormality of the second power supply passage 30B is detected by the detection part, electric conduction of the second power supply passage 30B is cut off by putting the second relay 22B in an OFF state.SELECTED DRAWING: Figure 1

    【課題】蓄電素子からモータへの電力供給経路に断線や地絡等の異常が生じた場合であっても車両の走行を継続することが可能な電源システム及び電気自動車を提供する。【解決手段】車両10に搭載される電源システム20であって、制御部は、検出部により第1電力供給経路30A及び第2電力供給経路30Bの異常が検出されていないときには、第1のリレー22A及び第2のリレー22Bをオン状態として第1電力供給経路30A及び第2電力供給経路30Bの通電を可能とする。検出部により第1電力供給経路30Aの異常が検出されたときには、第1のリレー22Aをオフ状態として第1電力供給経路30Aの通電を遮断し、検出部により第2電力供給経路30Bの異常が検出されたときには、第2のリレー22Bをオフ状態として第2電力供給経路30Bの通電を遮断する。【選択図】図1
