Abstract

Disclosed is a system and method for controlling charging of an electric vehicle. The system captures metadata and at least one input value from a user device present in a charging location. The metadata is associated with a charging device, installed at the charging location, capable of charging one or more electric vehicles. The at least one input value corresponds to at least one charging parameter of a plurality of charging parameters associated with charging of an electric vehicle belonging to a user of the user device. The system computes values corresponding to one or more other parameters of the plurality of charging parameters based upon the at least one input value captured from the user device. The system displays the values computed on the user device for validation by the user. The system further transmits one or more control commands to the charging device to charge the electric vehicle.
