1. An electric vehicle control device to control a plurality of induction motors with a single inverter, the electric vehicle control device comprising:
a first inverter to control a first electric motor group defined by a plurality of induction motors; and
a second inverter to control a second electric motor group defined by a plurality of induction motors, wherein
the induction motors belonging to the first electric motor group are mounted on different bogies,
the induction motors belonging to the second electric motor group are mounted on different bogies,
the first inverter and the induction motors belonging to the first electric motor group are connected to each other by a first conductor,
the second inverter and the induction motors belonging to the second electric motor group are connected to each other by a second conductor, and
between each of the first and second inverters and the bogies, a first length is equal to or less than three times an average value of a second length and a third length, the first length being an inter-center distance between the first conductor and the second conductor, the second length being a maximum length of a conductor portion of the first conductor in a cross section of the first conductor, the third length being a maximum length of a conductor portion of the second conductor in a cross section of the second conductor.
