PROBLEM TO BE SOLVED: To provide an electric drive system which can be controlled highly accurately by a plurality of voltage sensors without suppressing rated power.SOLUTION: The electric drive system includes: a plurality of fuel cell output voltage sensors 33 provided in same circuits C between a fuel cell 12 and a battery 21 and a drive motor 13; and an ECU 41 for controlling power supply from the fuel cell 12 and the battery 21 to the drive motor 13 based on measurement values of a drive inverter input voltage sensor 34 and a battery output voltage sensor 35. The ECU 41 performs error-compensation processing for compensating by detecting measurement values of the fuel cell output voltage sensor 33, the drive inverter input voltage sensor 34, and the battery output voltage sensor 35 while the voltage of the circuit C is in a steady state, and by determining errors between the fuel cell output voltage sensor 33, the drive inverter input voltage sensor 34, and the battery output voltage sensor 35. |
