BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a charging device for an electric vehicle in a parking lot, for charging a battery mounted on the electric vehicle during parking.

[0002]

2. Description of the Related Art Today, due to environmental problems and energy problems linked to them, electric vehicles equipped with a battery and powered by electricity are drawing attention, and their introduction is being actively considered. If electric vehicles become popular in the future,
Battery charging (updating) is a major issue. That is, it is necessary to deal with various problems such as the battery charging method, the power supply method, and the maintenance of the charging stand.

By the way, the method of charging the battery of this electric vehicle varies depending on its type, but the time until the charging is completed is faster than the refueling time of conventional gasoline and diesel vehicles even in the case of quick charging. It takes a relatively long time. For example, in a battery charging system that has recently been announced, it is known that it takes 6 minutes for a nickel-cadmium battery and 12 minutes for a lead battery to recover a capacity of 40%, respectively.

However, considering today's traffic conditions and land conditions, it is difficult to provide a charging station similar to a conventional gas station and take such a long time for charging one electric vehicle. In addition, it is desirable for the battery itself to be charged over time from the viewpoint of life.

[0005]

That is, in order for electric vehicles to become popular in the future, it is important to effectively charge the battery of the electric vehicle which requires a relatively long time.

Therefore, the present invention provides a charging device for an electric vehicle in a parking lot, which can charge the battery of the electric vehicle for a long time such as when the vehicle is temporarily parked or when returning home. With the goal.

[0007]

In order to achieve the above object, a charging device for an electric vehicle in a parking lot according to the present invention comprises:
A charger installed in a parking lot that supplies electric power to a battery mounted on an electric vehicle that is parked, a power supply control unit that controls the supply of electric power from the charger, and a vehicle mounted from the power supply control unit And a charge management unit for centrally managing charge information of electric power supplied to the battery.

[0008]

According to the present invention, the in-vehicle battery of the electric vehicle is supplied with electric power from the charger installed in the parking lot while the vehicle is parked through the electric power supply control section, and the charging management section provides information on charging electric power. Is centrally managed and the charging fee is settled based on that information, so that it is possible to use the battery for a long time when the vehicle is temporarily parked or when returning home.
