An intelligent charging system and method for electric vehicles based on mobile devices

Abstract

An electric vehicle intelligent charging system and method based on a mobile device belongs to the technical field of active intelligent control of electric vehicle charging. The system includes a grid management center, a station-level management server, mobile devices, charging equipment, and power batteries; the station-level management server includes a data input module, a data processing module, a data feedback module, and a historical data storage module, which are used to calculate solutions and realize real-time The optimal and orderly charging scheme; and output specific charging commands and feedback charging information to charging equipment and mobile equipment. The method uses a local optimal greedy algorithm to solve the real-time optimal and orderly charging scheme, realizes the user interaction characteristics, and performs data mining prediction on user data and power grid data, and performs performance analysis on power batteries, so as to give an electric vehicle effective charging scheme. sequential charging scheme. The present invention greatly satisfies the personalized needs of users and realizes the effective optimization of the power grid under the condition of ensuring less battery loss.
