To provide an electric vehicle and a railway system, which can keep operation costs low.SOLUTION: An electric vehicle 6 according to one embodiment comprises: a first power converter 8 that converts the voltage value of system power supplied from an overhead line 4 to a predetermined voltage value and outputs it; a second power converter 10 that converts the voltage value of the output power of the first power converter 8 to a predetermined voltage value and outputs it to an electric motor 11; a third power converter 12 that converts the voltage value of the output power of the first power converter 8 to a predetermined voltage value and outputs it to an auxiliary device 13; and a storage battery 9 that is charged by the output power of the first power converter 8 and is discharged when the output power of the second power converter 10 and the third power converter 12 exceeds the upper limit of outputtable power of the first power converter 8. The maximum outputtable power of the first power converter 8 is smaller than the maximum outputtable power of the second power converter 10 and is equal to or greater than the maximum outputtable power of the third power converter 12.SELECTED DRAWING: Figure 1
