(a) Technical Field
The present invention relates to a system for charging an electric vehicle using an in-cable control box (ICCB).
(b) Description of the Related Art
Recently, a system for slowly charging an electric vehicle has been used, in particular, electric vehicle station equipment (EVSE), and an electric charging system using an in-cable control box (ICCB).
An electric charging system using the EVSE is used by installing the EVSE, which is connected to an electricity distribution board, at a necessary position for performing work for supplying electric power. According to the electric charging system using the EVSE, the time required to charge the electric vehicle is comparatively short, and the time required to charge the electric vehicle may be reduced because of a capacity of the EVSE. In particular, an electricity rate applied for charging the electric vehicle, which is set by an electric power company, is the same for all users, such that a progressive tax is not imposed, and thus the electricity rate is low.
Referring to FIG. 2 (PRIOR ART), the electric charging system using the ICCB is used to charge the electric vehicle by connecting the ICCB 2 to a general power socket 1, which is used in the related art, and has an advantage in that the electric vehicle may be charged at any place where the power socket is installed, and separate installation costs are not required.
However, in the case of the electric charging system using the EVSE, there are problems in that high installation costs are incurred due to costs required to purchase the EVSE and costs required for work for supplying electric power, and there is a limitation on the type of place for charging the electric vehicle.
There are problems in that in the case of the electric charging system using the ICCB, because the electric vehicle is charged using a general domestic power socket, it is impossible to distinguish whether to charge the electric vehicle or a general electric device, and therefore, as electric consumption increases, a progressive tax is imposed, such that excessive costs are required for maintenance of the vehicle, and time required to charge the electric vehicle is increased in accordance with the rating of the power socket connected with the ICCB.
The above information disclosed in this Background section is only for enhancement of understanding the background of the invention and therefore it may contain information that does not form the prior art that is already known in this country to a person of ordinary skill in the art.
