System and method for supplying power to electromotive vehicle

The invention discloses a system and method for supplying power to an electromotive vehicle. According to the method, a mobile terminal, a server and a charging pile are arranged; the mobile terminal is used for sending a charging request to the server, receiving charging evidence returned by the server and outputting the charging evidence to the charging pile, wherein the charging request comprises a charging type selected by a user and user account information; the server is used for responding to the received charging request to meet a preset verification rule and returning the charging evidence to the mobile terminal; the charging pile is used for responding to the input charging evidence to instruct to be connected with a charging interface of the electromotive vehicle and lock connection through an electronic lock and supplying the power to the electromotive vehicle. In this way, the mobile terminal is effectively utilized for conducting data transmission, the traffic cost is reduced, the lost connection risk of a transmission link is reduced, and the cost of enabling the charging pile to have access to the Internet is reduced.
