Abstract: A vehicle includes: a first power line configured to connect an inlet and an energy storage device via a power conversion device; a second power line configured to connect the inlet and the energy storage device without via the power conversion device; a first relay configured to switch between a first electrically connected state in which the second power line is electrically connected and a first electrically disconnected state in which the second power line is electrically disconnected; and a first control device. The first control device is configured to switch the first relay to the first electrically disconnected state when a voltage that can be supplied from the external power supply is lower than a voltage range in which the energy storage device can be charged.

Abstract: Electric Vehicle Supply Equipment determines the output power maximum value and the output current maximum value by using the voltage VB of the battery prior to starting the charge. The output power maximum value and the output current maximum value are set to be smaller when the voltage is low than when the voltage is high. The outputtable current value is calculated based on the maximum output power value, and the outputtable current value is set to be smaller when the voltage is low than when the voltage is high.

Abstract: The electrified vehicle includes a power storage device, a connector, a buck-boost converter that exchanges power with voltage conversion between a first power line to which the power storage device is connected and a second power line to which the connector is connected; A charging relay provided on the second power line, and a control device that controls the buck-boost converter and the relay, and the control device is connected to the connector and the external power supply device and before turning on the charging relay. The voltage of the converter side portion of the second power line that is closer to the buck-boost converter than the charging relay is adjusted based on the voltage of the connector side portion of the second power line that is closer to the connector than the charging relay. The buck-boost converter is controlled so that the
