POWER TRANSMISSION SYSTEM FOR ELECTRICALLY POWERED VEHICLE

A power transmission system for an electrically powered vehicle including a battery that stores power for traveling and an electric device that receives the power from the battery includes a power intake unit that can take in power from a charging facility, a charger that charges the battery using the power, first and second power lines that transmit the power respectively between the electric device and the battery and between the battery and the charger, a relay that can cut off the first power line without cutting off the second power line, and a controller that controls the relay. The controller disconnects the relay after performing current generation processing when a request for disconnecting the relay is issued based on an abnormality. The current generation processing causes a current flowing in a direction in which a current of the relay decreases to flow between the charger and the battery.
