Comparison of three network access schemes for charging piles
Plan A
Each charging pile is connected to Ethernet through RJ45 or optical fiber respectively, connected to the charging station management center, and then connected to the Internet management center and database.
Advantages: The main advantages of wired Ethernet are reliable data transmission and large network capacity;
Disadvantages: complex wiring, poor expansion, high construction cost, poor flexibility.
Plan B
The charging station is connected to the concentrator through an industrial serial bus (RS485/RS232/CAN), and then the concentrator is connected to the service management platform and database through RJ45 or optical fiber Ethernet or mobile data access service
Advantages: reliable data transmission, simple design;
Disadvantages: complex network, poor expansion, high construction cost, poor flexibility, low communication capacity.
Plan C
The charging station is connected to the concentrator through an industrial serial bus (RS485/RS232/CAN), and then the concentrator is connected to the service management platform and database through RJ45 or optical fiber Ethernet or mobile data access service.
Advantages: reliable data transmission, simple design;
Disadvantages: complex network, poor expansion, high construction cost, poor flexibility, low communication capacity.
