Global Standards for EV Charger Piles

Standards:

• IEC 61851; lEC (The International Electrotechnical Commission);

• SAEJ 1772; SAE (Society of Automotive Engineers of United States);

• GB/T 20234; GB (China National Standard)

• CHAdeMo (Japan)

Note:

• The IEC standard is a standard used in Europe, initiated and established by the International Electrotechnical Commission. On this basis, the EU has switched to the EN series standards: EN IEC 61851;

• SAE J1772 is a standard initiated and established by SAE in the United States. American Society of Motor Vehicle Engineers;

• GB is a Chinese national standard;

• CHAdeMO is a fast charging standard initiated by Japanese companies in the industry. Only includes DC charging interface and off board charging machine standards;

These standards decide the charging methods, communication standards, and plug sockets, among others. And different charging facilities of different standards cannot be fully compatible. And some adapters can be used for switch between different standards.
