    Abstract: Methods and systems for managing charging stations for electric vehicles are described. According to one aspect of the present invention, an identity of a user driving a vehicle and contact information are obtained when the vehicle is detected to occupy a charging station or charger for charging the vehicle. The user is then periodically updated of the charging status and notified of the completion when the charging has reached to the full capacity of battery in the vehicle or a predefined charging level set by the user. A fee is assessed when the vehicle has not been removed from the charger after a predefined period (e.g., 5 minutes). As a result, a charging station or a charger can be used more efficiently as the demand for charging stations and the EVs are getting popular.
