System structure of electric vehicle charging station

The charging station can be divided into four sub-modules according to its functions: power distribution system, charging system, battery dispatching system, and charging station monitoring system. The charging station can charge the car in three ways: ordinary charging, fast charging and battery replacement. Normal charging is mostly AC charging, and 220V or 380V voltage can be used. Fast charging is mostly DC charging. The main equipment of the charging station includes charger, charging pile, active filter device and electric energy monitoring system.
The implementation of the charging and charging system for electric vehicles consists of three parts, which are described below:
1. Build a charging and billing system management platform to centrally manage the basic data involved in the system, such as electric vehicle information, power purchase user information, asset information, etc.
2. Build a charging and charging system operation platform for the operation and management of charging and discharging of electric vehicles and charging of electric consumers.
3. Build a charging and billing system query platform for comprehensive query of relevant data generated by the management platform and operation platform
