What is the essential difference between the American standard charging pile control board and the national standard charging pile control board?

There are significant differences between the American standard charging pile control board and the national standard charging pile control board in terms of interface standards, communication protocols, electrical design, safety standards, and functional design. The following is a detailed analysis:

1. Interface standards

American standard charging pile control board: Follow SAE J1772 standard, use Type 1 (SAE J1772) interface, and apply to North America, South Korea, Taiwan, China and other regions. This interface design allows vehicles to use both slow and fast charging simultaneously.

National standard charging pile control board: Following the GB/T 20234 standard, it is divided into two interfaces: slow charging (AC) and fast charging (DC). The slow charging interface is suitable for charging stations below 7kW, while the fast charging interface is suitable for higher power DC charging stations.

2. Communication Protocol

American standard charging station control board: The communication protocol is based on SAE J1772 and SAE J2847 standards, supporting PLC (Power Line Communication) communication to ensure data transmission between the charging station and the vehicle.

National standard charging station control board: The communication protocol follows the GB/T 27930 standard and is based on CAN bus communication to ensure real-time data exchange between the charging station and the vehicle battery management system (BMS).

3. Electrical design

American standard charging station control board: The design needs to adapt to the power grid standards in North America, support 120V AC or 240V AC input voltage, and the rated current is usually 16A or 32A.

National standard charging pile control board: The design needs to adapt to the Chinese power grid standards, support 220V AC input voltage, and the rated current can be 10A, 16A, or 32A.

4. Safety standards

American standard charging station control board: It must meet safety standards such as UL 2202 and UL 2231 to ensure the safety of the charging process.

National standard charging pile control board: It must meet standards such as GB/T 18487.1-2015 to ensure electrical and operational safety during the charging process.

5. Functional design

American standard charging station control board: It has good processing and safety performance, can automatically detect the power status and operating status of the charging station system, and monitor the current, voltage, and temperature during the charging process.

National standard charging station control board: supports multiple charging modes, such as timed charging, quantitative charging, automatic full charging, etc., to meet the different charging needs of users.

summarize

The main differences between the American standard charging pile control board and the national standard charging pile control board are interface standards, communication protocols, electrical design, safety standards, and functional design. The American standard control board follows the SAE J1772 standard, supports Type 1 interface, and the communication protocol is based on SAE J1772 and SAE J2847 standards, suitable for power grid standards in North America and other regions. The national standard control board follows the GB/T 20234 standard and supports both slow and fast charging interfaces. The communication protocol is based on the GB/T 27930 standard and is suitable for the power grid and vehicle standards in the Chinese market.
