Power supply apparatus for vehicles that selects between conductive and non-conductive power transfer

摘要

A power supply apparatus for vehicles is provided. This apparatus includes a battery mounted on a vehicle as well as first and second power transferring means and a power conversion unit. The first power transferring means transfers power between the battery and a first power supply section placed outside the vehicle, in a state where the battery is electrically connected to the power supply section. The second power transferring means transfers power between the battery and the power supply section placed outside the vehicle, in a state where the battery is electromagnetically connected to a second power supply section. The power conversion unit is used commonly in both the first and second power transferring means and used for transferring the power between the battery and the first power supply section and for transferring the power between the battery and the second power supply section.

主权项

1. A power supply apparatus for vehicles, comprising:
a battery mounted on a vehicle; first power transferring means comprising a connector for transferring power between the battery and a first power supply section placed outside the vehicle when the battery is electrically connected to the first power supply section through the connector and a charger-side connector is connected to the first power supply section,
the connector being disposed in an opening of the vehicle that is opened and closed with a charging lid; second power transferring means for transferring power between the battery and a second power supply section placed outside the vehicle when the battery is electromagnetically connected to the second power supply section; a power conversion unit used commonly in both the first and second power transferring means and used for transferring the power between the battery and the first power supply section and for transferring the power between the battery and the second power supply section; and a control section for controlling transferring of power through the first power transferring means and the second power transferring means, the control section being configured to:
detect whether the connector connected to the first power transferring means is electrically connected to the charger-side connector connected to the first power supply section,stop power transfer through the second power transferring means in response to detecting the electrical connection between the connector and the charger-side connector during the power transfer through the second power transferring means,after stopping the power transfer through the second power transferring means, allow the power conversion unit and the first power transferring means to transfer power from the first power supply section to the battery, andstop the power transfer through the second power transferring means and instruct the first power transferring means to be ready to transfer power from the first power supply section to the battery based on a detection that at least one of the charging lid and a vehicle door is opened during the power transfer through the second power transferring means.
