Embodiment Construction

[0042] Hereinafter, one embodiment of the present invention will be described with reference to the drawings.

[0043] figure 1 It is a figure showing the structure of the charging system S comprised by combining the vehicle V and the external charger C of this embodiment. In the following, a case where the vehicle V is a so-called hybrid vehicle including an unillustrated engine and the travel motor 70 as power generation sources for driving drive wheels will be described, but the present invention is not limited thereto. The present invention can also be applied to an electric vehicle having only an electric motor as a power generation source.

[0044] The external charger C includes: an external power supply 90 that outputs alternating current (specifically, for example, AC200V); a user-operable charging connector 93 ; and a charging cable 92 that connects the external power supply 90 and the charging connector 93 . When the user uses the external charger C to charge the ...

Abstract

The present invention provides a vehicle capable of starting external charging without consuming additional electric power. The vehicle (V) is equipped with a high-voltage battery (2), an on-board charger (54), an inlet (51), a charging ECU (60) that controls the on-board charger (54), and a transmission that transmits driving force to the driving wheels. The rotation shaft (80) of (81) is a parking lock mechanism (82) in a rotatable or non-rotatable state. A charging ECU (60) includes a backup RAM (60a) in which lock state information of a parking lock mechanism (82) is written. When charging the high-voltage battery (2) by connecting the charging connector (93) of the external charger (C) to the inlet (51), the charging ECU (60) uses the information stored in the backup RAM (60a) to Controls the on-board charger (54).

Description

technical field [0001] The present invention relates to vehicles. More specifically, it relates to a vehicle capable of supplying electric power from an external electric power supply source to an electric storage device via an on-vehicle charger. Background technique [0002] An electric vehicle travels by driving an electric motor using electric power supplied from a battery. In addition, a battery mounted on an electric vehicle can be charged by connecting a connector of a charging cable connected to a power supply source outside the vehicle, such as a general charging facility or a quick charging facility, to an inlet provided on the electric vehicle. Such external charging is also possible with the car parked on sloped ground. However, in this case, if the external charging is started without actuating the so-called parking lock mechanism, the vehicle may move during the external charging and the charging cable may be disconnected during energization.
