The present invention relates to a device and a method to manage a charge of an electric vehicle. More specifically, the device and the method are capable of controlling the charge of the electric vehicle in accordance to the charging conditions inputted by a user, or of displaying a remaining battery by a display installed to be adjacent to a charging unit of the electric vehicle. According to an embodiment of the present invention, charge management can be realized regardless of charging infra levels by reflecting a user-customized charge management policy even in cases of charging the electric vehicle using a commercial power at home or of unilaterally charging the electric vehicle in a wireless manner; and supplementary materials can be provided to prove power consumption when there is a conflict of power consumption between a power supplier and a power receiver. Furthermore, the remaining battery of the electric vehicle can immediately and simply be checked through the display mounted outside the vehicle without a separate device or procedure, thereby allowing a user to conveniently check the battery charging progress on the outside and simply check the battery charging status of the electric vehicle even in a state of not charging the electric vehicle. Therefore, the electric vehicle user can immediately check the remaining battery of a vehicle before authentication during usage of the electric vehicle through car sharing, thereby improving the convenience of use in car sharing. |
