Introduction:
The widespread adoption of electric vehicles (EVs) has led to the development of global standards for charging systems to ensure compatibility and safety. This blog post explores key standards established by prominent organizations such as the International Electrotechnical Commission (IEC), the European Committee for Electrotechnical Standardization (CENELEC), the Society of Automotive Engineers (SAE), and the Japan Electric Vehicle Association (CHAdeMO), as well as China's GB/T standards.
IEC Standards:
The IEC 61851 series is among the earliest international charging system standards, providing vital reference points for other countries' standards. IEC 61851-1 outlines general requirements for charging systems, applicable to both AC and DC charging equipment for vehicles with nominal voltages up to 1000V AC and 1500V DC. The standard defines four charging modes, three connection methods, and related requirements for electric vehicles.
EN Standards:
The European Union's standards for electric vehicle charging systems include the EN 61851 and EN 62196 series. These standards cover charging equipment, stations, plugs, sockets, and communication protocols, aligning with corresponding IEC international standards.
SAE Standards:
SAE standards are largely compatible with corresponding IEC standards. SAE J1772 corresponds to IEC 61851 requirements, specifying additional details related to charging interfaces. SAE J2847 standards define communication requirements between electric vehicles and the grid, outlining specifications for communication between non-vehicle charging equipment. SAE J2953 focuses on interoperability requirements and testing specifications for EVs and plug-in hybrid electric vehicles (PHEVs) with charging facilities (EVSE).
Conclusion:
Global collaboration has led to the establishment of comprehensive standards for electric vehicle charging systems, fostering interoperability, safety, and efficient communication between vehicles and charging infrastructure. These standards play a crucial role in the development of a reliable and widespread charging infrastructure to support the growing electric vehicle market.
