Since an electric vehicle obtains the driving energy of the vehicle from electricity, the electric vehicle must receive power from the charger from time to time. Chargers for charging an electric car are generally installed in a public parking lot such as an apartment parking lot, and it takes a considerable time until charging is completed. Therefore, when there are many electric vehicles waiting to be charged, there is a problem that the time for the electric vehicle to stay for charging becomes long.

In addition, since electric vehicles are not commercialized compared to gasoline vehicles or diesel vehicles, the charging stations or chargers for charging electric vehicles are not provided.

In addition, when it is determined that charging is necessary while driving on the road, the driver generally searches for the charger located near the road. However, if the section to the charger located in the vicinity is delayed, the electric vehicle may be delayed for a long time on the road, which may result in discharge.

Electric vehicles also require longer charging times than gasoline or diesel vehicles. Therefore, even when the charger is visited with difficulty, there is an inconvenience to wait for a long time if another electric vehicle is already connected to the charger.
