VEHICLE
First Claim
1. A vehicle capable of being connected to an external power supply, comprising:
- a first power storage device storing electric power for obtaining a driving force of said vehicle;
a charger performing a charging process for charging said first power storage device with electric power from said external power supply;
a first power supply switch turned on in response to connection operation of connecting said external power supply to said vehicle by a user, to supply electric power for rendering said charger active to said charger; and
a controller rendered active in response to operation by the user different from said connection operation,said controller forcibly outputting an ON signal for turning said first power supply switch on to said first power supply switch while being active in response to said different operation, and determining whether or not an abnormality resulting in inability to perform said charging process has occurred based on whether or not said first power supply switch has been turned on in response to said ON signal.

Abstract
A vehicle is a vehicle in which a high-voltage power supply can be charged with electric power from an external power supply. In a travel mode, a main microcomputer (MMC) of a controller outputs a request signal requesting to forcibly turn a plug-in main relay (PIMR) on to a sub-microcomputer (SMC), in order to activate a charging system that is essentially not required to be activated. Upon receiving the request signal, the SMC outputs a signal for turning the PIMR on to the PIMR. If the MMC does not receive electric power from a low-voltage power supply via the PIMR after outputting the request signal, the MMC determines that there is an abnormality in an activation circuit for the charging system, and alerts a user.
