Electric vehicle charging automatic management system and method

Abstract

The invention discloses an electric vehicle charging automatic management system and method. The system comprises a control unit, a communication unit, a display unit, an electric energy measurement unit and an electric energy distribution unit. The electric energy measuring unit is used for detecting real-time charging quantity information of the electric vehicle and transmitting the charging quantity information to the control unit; the electric energy distribution unit is used for charging the electric vehicle in different periods according to the electric energy demand of the electric vehicle and the transformer secondary side total load; the communication unit is used for transmitting the charging state information of the electric vehicle to a cloud, a vehicle terminal or a user mobile control terminal; the display unit is used for displaying the charging state information of the electric vehicle to a user. The invention further discloses an automatic management method. According to the invention, time-phased management is carried out on the charging demand of the user through time-phased pricing in real time, and the scheduling target of peak load shifting is achieved.

Description

technical field [0001] The invention relates to the technical field of electric vehicle charging, in particular to an electric vehicle charging control system and method.
