Abstract
Official abstract text for this publication.
A vehicle includes an electric-device temperature acquisition unit, a charging controller, and a predicted charging time deriving unit. The electric-device temperature acquisition unit acquires a temperature of an electric device disposed in a current path for external charging for supplying electric power from a power supply external to the vehicle to a battery mounted in the vehicle. The charging controller pauses a supply of electric power to the battery in response to the temperature of the electric device becoming greater than or equal to a first threshold during the external charging, and resumes the supply of electric power to the battery in response to the temperature of the electric device becoming less than a second threshold lower than the first threshold. The predicted charging time deriving unit derives a predicted charging time predicted to be taken for the external charging in accordance with an instruction for the external charging.
First claim
Opening claim text (preview).
The invention claimed is: 1. A vehicle comprising: an electric-device temperature acquisition unit configured to acquire a temperature of an electric device disposed in a current path for external charging for supplying electric power from a power supply external to the vehicle to a battery mounted in the vehicle; and a predicted charging time deriving unit configured to derive a predicted charging time that is a time predicted to be taken for the external charging in accordance with an instruction for the external charging, and when an expected temperature of the electric device at a time of completion of the external charging is predicted to be greater than or equal to a travel-preparation threshold, derive a travel-preparation time and extend the predicted charging time by the travel-preparation time, the travel-preparation time being a period of time from the time of completion of the external charging until the temperature of the electric device becomes less than the travel-preparation threshold. 2. A vehicle comprising: circuitry configured to acquire a temperature of an electric device disposed in a current path for external charging for supplying electric power from a power supply external to the vehicle to a battery mounted in the vehicle, derive a predicted charging time that is a time predicted to be taken for the external charging in accordance with an instruction for the external charging, and when an expected temperature of the electric device at a time of completion of the external charging is predicted to be greater than or equal to a travel-preparation threshold, derive a travel-preparation time and extend the predicted charging time by the travel-preparation time, the travel-preparation time being a period of time from the time of completion of the external charging until the temperature of the electric device becomes less than the travel-preparation threshold.
