Electrified vehicle

An electrified vehicle including

• an energy storage device,
• a traction motor including a three-phase open-end winding,
• a first inverter including a first upper arm and a first lower arm, the first inverter being connected to a power line to which the energy storage device is connected, and being connected to a first end of the three-phase open-end winding,
• a second inverter including a second upper arm and a second lower arm, the second inverter being connected to the power line at a position on an opposite side of the first inverter from the energy storage device, and being connected to a second end of the three-phase open-end winding,
• a switch provided on the power line at a position between the first inverter and the second inverter, and
• a controller configured to control the first inverter, the second inverter, and the switch,
• wherein the controller is configured to determine that the switch has failed open, when the controller confirms that an absolute value of a zero-sequence current is equal to or greater than a threshold while the switch is on and the first inverter and the second inverter are being driven to perform switching, the zero-sequence current being a sum of phase currents of three phases.
