Electric-motor vehicle, power equipment, and power supply system including limiting discharging after the power storage device is externally charged

摘要

A vehicle includes a power storage device, a power node, and a controller. The controller controls charging and discharging of the power storage device with respect to the outside of the vehicle when the power storage device is able to be charged or discharged with electric power with respect to the outside of the vehicle via the power node. The controller controls discharging of electric power from the power storage device so as to provide a first period in which discharging of electric power from the power storage device to the outside of the vehicle is limited after the power storage device is externally charged with a power supply outside the vehicle, and so as to provide a second period in which discharging limitation in the first period is released at least after the first period ends.

1. A power equipment configured to give and receive electric power to and from an electric-motor vehicle having a power storage device mounted thereon, the power equipment comprising:
a power node configured to give and receive electric power to and from the electric-motor vehicle; and a controller configured to control charging and discharging of the power storage device with respect to the power equipment when electric power is able to be given and received between the power equipment and the electric-motor vehicle via the power node by charging and discharging of the power storage device, the controller configured to control discharging of electric power from the power storage device to the power equipment so as to provide a first period in which discharging of electric power from the power storage device to the power equipment is limited after the power storage device is externally charged, and the controller configured to control discharging of electric power from the power storage device to the power equipment so as to provide a second period in which discharging limitation in the first period is released at least after the first period ends, wherein the controller is configured to permit discharging of electric power from the power storage device until a state of charge of the power storage device is lowered to a first value in the first period and to permit discharging of electric power from the power storage device until the state of charge is lowered to a second value in the second period, and wherein the first value is greater than the second value.
