VEHICLE CHARGING SYSTEM AND VEHICLE CHARGING METHOD

摘要

In response to connection of a vehicle with an external power supply, a PLG-ECU performs a first charging operation of controlling a charger using a target value which is set to a state of charge lower than a predetermined full state of charge, until the state of charge of a power storage device reaches the target value. After the state of charge reaches the target value, the PLG-ECU stops charging of the power storage device, and restarts charging of the power storage device so that the state of charge reaches the predetermined full state of charge at a scheduled time to end charging which is specified through the use of an input unit.

主权项

1. A vehicle charging system for controlling charging of a power storage device mounted in a vehicle, comprising:
a charger configured to be capable of converting electric power from an external power supply into charging electric power for said power storage device; an input unit for specifying a scheduled time to end charging said power storage device; and a controller for controlling said charger so that a state of charge of said power storage device reaches a predetermined full state of charge, said controller being configured to perform, in response to connection of said vehicle with said external power supply, a first charging operation of controlling said charger using a target value which is set to a state of charge lower than said predetermined full state of charge, until said state of charge reaches said target value, said controller being configured to stop, after said state of charge reaches said target value, charging of said power storage device, and restart charging of said power storage device for performing a second charging operation of controlling said charger so that said state of charge reaches said predetermined full state of charge at said scheduled time to end charging, and said controller changing said target value in accordance with a learned value of said state of charge at a time when travel of said vehicle is completed.
