An electric vehicle moves by rotating its motor using electricity stored in a battery. Such electric vehicle was developed before of the development of a typical vehicle using an internal combustion engine. However, practical limitations of the electrical vehicle caused by the weight and the time required to charge its battery hindered the full commercialization of the electric vehicle. But, the environmental concerns of using the internal combustion engine have revitalized a further development of the electric vehicle.
The electric vehicle is similar to other typical vehicles with internal combustions engines except that it has an electric motor instead of a combustion engine. Unlike a typical vehicle, an important issue of the electric vehicle development is to reduce the size and the weight of the battery corresponding to its energy source. Particularly, reducing the time required to charge the battery is a critical element for the full commercialization of the electric vehicle.
For charging such a battery, an electric vehicle is hooked up to an electric charging unit and a driver of the electric vehicle waits for a comparatively long time until the electric vehicle is fully charged. During such a waiting period, various services may be provided to the driver through electronic devices mounted on the electric vehicle or a portable device of the driver.

DETAILED DESCRIPTION OF THE INVENTION
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to like elements throughout. The embodiments are described below, in order to explain the present invention by referring to the figures.
In accordance with at least one embodiment, a multimedia contents service may be provided to user equipment associated with an electric vehicle coupled to one of electric charging units in an electric vehicle charging station. A wireless access point may be installed in the electric vehicle charging station and assigns an IP address to user equipment when the user equipment is associated with an electric vehicle located in an electric vehicle charging station. The multimedia contents service may be provided through the assigned Internet protocol (IP) address. Before describing at least one embodiment of the present disclosure, a related technology for a multimedia content service will be discussed briefly with reference to FIG. 1.
FIG. 1 illustrates an electric charging station for providing a multimedia contents service to an electric vehicle.
Referring to FIG. 1, an electric vehicle charging station may be a station for supplying electric energy for the recharging of plug-in electric vehicles. For example, typical electric vehicle charging station 10 may supply electric energy to an electric vehicle coupled to an electric charging unit. Such electric vehicle charging station 10 may include a plurality of electric charging units (e.g., electric vehicle changing unit 15) and management server 20. Electric charging unit 15 may be coupled to an electric vehicle through a physical cable (e.g., electric wire) and supply electric energy to the electric vehicle through the physical cable in response to control of management server 20. The physical cable may be used to transmit signals (e.g., multimedia contents) to and receive signals (e.g., status information) from the electric energy as well as supplying electric energy to an electric vehicle. Management server 20 may be a computing system for monitoring and managing a plurality of corresponding electric charging units and electric vehicles coupled to the electric charging units.
Particularly, management server 20 may be connected to electric charging unit 15 and provide predetermined contents to an electric vehicle hooked up to electric charging unit 15 through the physical cable connected between electric charging unit 15 and the electric vehicle while electric charging unit 15 supplies electric energy to the electric vehicle. The predetermined multimedia contents may include text message for charging status, News, advertisements, movies, TV shows, and so forth. The predetermined multimedia contents may be played back through an output device (e.g., a display and a speaker) mounted on an electric vehicle. Such a multimedia contents service may entertain customers (e.g., drivers and passengers of electric vehicles) while waiting for finishing charging an electric vehicle.
In order to provide such multimedia contents, electric vehicle charging station 10 requires having management server 20 physically installed in electric vehicle charging station 10. Management server 20 may be coupled to contents server 30 through a communication network. Such requirements may increase a cost of building and maintaining each electric vehicle charging station 10. Furthermore, since multimedia contents are provided to a device mounted on corresponding electric vehicle, customers have to stay inside an electric vehicle to watch the received multimedia contents.
Each electric vehicle charging station 10 includes independent management server 20 not coupled with others through a communication network. Furthermore, management server 20 installed at one company's electric vehicle charging station may be not compatible with other servers installed at the other company's electric vehicle charging stations. Accordingly, it may be not an efficient way of managing stations and customers. For example, it could be more efficient to attract future customers if advertisement contents are selected and provided to a customer based on a customer's history of watching multimedia contents provided from management server 20. Typical electric vehicle charging station 10 may not efficiently collect and manage such information of customers with other electric charging stations. Furthermore, a customer might leave one electric vehicle charging station in the middle of watching a streaming content of a movie when an electric vehicle is completely charged. If the customer visits another electric vehicle charging station and wants to continuously watch the movie, the customer may have to start over or personally find a place where the customer left off.
In accordance with at least one embodiment, a multimedia contents service may be provided to user equipment associated with an electric vehicle located at an electric vehicle charging station through a wireless access point installed at the electric vehicle charging station in connection with a service server installed at a remote location in a distance from the wireless access point. Hereinafter, an electric vehicle charging station in accordance with at least one embodiment will be described with reference to FIG. 2.

Furthermore service server 200 may be coupled to a plurality of wireless access points each installed at different electric vehicle charging stations and manage the plurality of wireless access points. For example, service server 200 may receive information on user equipment 120 and associated electric vehicle 130 from wireless access point 110 and manage the received information. Service server 200 may use such stored information to manage user equipment 120 and associated electric vehicle 130. Particularly, service server 200 may use the stored information to confirm whether user equipment 120 sending a connection request message is associated with electric vehicle 130 being charged at electric vehicle charging station 100. Furthermore, service server 200 may receive status information of electric vehicles and manage registered electric vehicles to efficiently provide a related service to electric vehicles.
Service server 200 may store information necessary for providing a multimedia contents service to registered user equipment and electric vehicles. For example, service server 200 may store various multimedia contents such as text messages, advertisements, movies, games, information related for shopping, finance, and a trip. Service server 200 may store and provide a dedicated application for the multimedia contents service or for an electric vehicle charging service. The present invention, however, is not limited thereto. Service server 200 may be coupled to contents server 300 and obtains contents requested by user equipment 120 from contents server 300.
Contents server 300 may be a separate computing system that stores various multimedia contents. Contents server 300 may provide multimedia contents directly to user equipment 120 in addition to multimedia contents provided by service server 200 or receives a request message for requesting predetermined multimedia contents from service server 200 and provide the requested multimedia contents to service server 200.
