Problems solved by technology

[0003] In such an electric vehicle, there is a problem that the user of the vehicle forgets that the vehicle is being charged while the external power source is connected to the vehicle via the charging cable, such as switching the shift lever to the drive position.
Therefore, even if the charging condition is restored after the charging is stopped, the charging condition of the charging device cannot be judged due to the interruption of the power supply, so the charging cannot be restarted.
In this case, the user mistakenly thinks that charging is continuing, and therefore there is a problem that the remaining battery power is insufficient for the next drive

Abstract

A charging device for an electric vehicle is disclosed. A mal-operation detection unit detects whether a start operation part is operated mistakenly by an electric vehicle user; when mal-operation is detected by the a charging control unit during processes where batteries in the electric vehicle are charged by an external power source arranged outside the electric vehicle, the batteries are kept being charged.

Description

technical field [0001] The present invention relates to an electric vehicle including an electric motor for driving the electric vehicle and a battery for supplying electric power to the electric motor, and more particularly, the present invention relates to a charging device for the electric vehicle capable of charging the battery. Background technique [0002] As an electric vehicle, a so-called plug-in hybrid vehicle including a charging device capable of charging a battery of the vehicle from an external power source is known. According to the electric vehicle charging device, the charging plug provided at the front end of the charging cable of the external power supply outside the vehicle is inserted into the charging socket provided in the vehicle, so that the external power supply and the battery are connected to each other via the charging cable to charge the battery. [0003] In such an electric vehicle, there is a problem that the user of the vehicle forgets that t...
