5 Common Data Model
Common information encompasses five core categories. operator information, charging and battery swap station information, charging and battery swap station billing policy information, charging and battery swap station equipment operating status information, and battery information.
Operator information is used to describe basic enterprise information related to infrastructures, including platform operator information, equipment owner information, and charging and battery swap service enterprise information.
Charging and battery swap station information is used to describe basic information of charging and battery swap stations, including basic charging business information and basic battery swap business information. In the basic charging business information, each charging station contains at least one charging equipment, and each charging equipment corresponds to one or more charging interfaces. In the basic battery swap business information, each battery swap station contains at least one battery swap equipment, and each battery swap equipment corresponds to one or more battery pack replacement equipment and quick-swap battery pack racks.
Charging and battery swap station billing policy information is used to describe various billing rules for charging and battery swap stations, including charging billing policy information and battery swap billing policy information. Charging billing policy information includes charging interface billing policy information and parking space usage fee information; battery swap billing policy information includes battery pack replacement equipment billing policy information and battery usage fee information.
The charging and battery swap station equipment operating status information is used to describe the real-time status of various equipment within the station, including the operating status of charging equipment interfaces, battery pack replacement equipment and quick-swap battery pack racks.
Battery information is used to describe basic battery-related information and real-time status, including basic battery pack information and battery operating status information.
The common information object relation diagram is shown in Figure 2.
The definition of common information objects shall comply with the requirements of Appendix B. ......
