Vehicle

A vehicle, comprising:

• a battery configured to accumulate electric power for travel of the vehicle;
• an electric power acquirer configured to acquire charging electric power for the battery, from outside the vehicle;
• a power line including a first power line electrically connected to a positive electrode of the battery and a second power line electrically connected to a negative electrode of the battery, the power line being electrically connected to at least one of an electric device of the vehicle other than a travelling motor of the vehicle or a power receptacle of the vehicle, the power line being further electrically connected to the electric power acquirer,
• a main relay configured to switch electrically connecting between the battery and the power line, the main relay including a first relay through which the first power line is electrically connected to the positive electrode and a second relay through which the second power line is electrically connected to the second electrode;
• a pre-charge relay and a pre-charge device, the pre-charge relay and the pre-charge device being coupled in parallel to one of the first relay and the second relay so that the pre-charge relay being allowed to couple the battery and the power line through the pre-charge device;
• a power supply unit configured to receive electric power from the power line and supply a power supply voltage to the electric device;
• and
• a controller configured to perform a control of electric power transmission through the power line,
• the controller being configured to
• execute pre-charge processing on a request for operation of the power supply unit, with the main relay being in a state where the one of the first relay and the second relay is turned off and another of the first relay and the second relay is turned on, and with the electric power acquirer being available for electric power acquisition, the pre-charge processing including turning on the pre-charge relay to raise a voltage between the first power line and the second power line, and
• cause, sequentially following the executing the pre-charge processing, a transition of a mode of the electric power transmission to a first direct transmission mode, the first direct transmission mode including transmitting electric power acquired by the electric power acquirer to the power supply unit in a state where the pre-charge relay is turned off, and the first relay, the second relay or both of the first relay and the second relay are turned off.
