Abstract
A motor-driven vehicle includes a power storage device, a charging inlet, a voltage conversion device, a first power line connected the charging inlet and a first node, a second power line connected the charging inlet and a second node, and a switching relay configured to switch between a first state and a second state. The first state is a state in which the charging inlet is connected to the power storage device via the first power line without passing through the second power line is connected to the power storage device via the second power line without passing through the first power line.
Claims6
A motor-driven vehicle comprising:
- a power storage device configured to store electric power that is supplied to an electrical load;
- a charging inlet configured to be supplied with electric power from an external power supply;
- a voltage conversion device disposed between the power storage device and an inverter;
- the inverter disposed between the voltage conversion device and the electrical load;
- a first power line configured to connect the charging inlet and a first node between the power storage device and the voltage conversion device;
- a second power line configured to connect the charging inlet and a second node between the voltage conversion device and the inverter;
- and
- a switching relay configured to switch between a first state and a second state,
- the first state being a state in which the charging inlet is connected to the power storage device via the first power line without passing through the second power line, and the second state being a state in which the charging inlet is connected to the power storage device via the second power line without passing through the first power line.
A control method for a motor-driven vehicle,
- the motor-driven vehicle including a power storage device configured to store electric power that is supplied to an electrical load, a charging inlet configured to be supplied with electric power from an external power supply, a voltage conversion device disposed between the power storage device and an inverter, the inverter disposed between the voltage conversion device and the electrical load, a first power line configured to connect the charging inlet and a first node between the power storage device and the voltage conversion device, a second power line configured to connect the charging inlet and a second node between the voltage conversion device and the inverter, a switching relay configured to switch between a first state and a second state, and an electronic control unit configured to control the switching relay, the first state being a state in which the charging inlet is connected to the power storage device via the first power line without passing through the second power line, the second state being a state in which the charging inlet is connected to the power storage device via the second power line without passing through the first power line,
- the control method comprising:
- switching, by the electronic control unit, the switching relay to one of the first state and the second state using a maximum output of the external power supply acquired by communication from the external power supply when the charging inlet is supplied with electric power from the external power supply.
