Analysis of European DC charging standards for electric vehicles
The European electric vehicle charging standard CCS2 is a combined standard that integrates AC charging and DC charging. The combined charging system is an open international standardized system mainly promoted by Audi, BMW, Chrysler, Daimler, Ford, General Motors, Porsche and Volkswagen. Vehicles exported to Europe need to meet their physical interface and communication requirements.
The main European electric vehicle charging standards are:
1. Interface standards: IEC 62196-1, IEC 62196-2, IEC 62196-3.
2. Power supply standards: IEC 61851-1, IEC 61851-21, IEC 61851-22, IEC 61851-23.
3. Vehicle standards: ISO 6469-3, ISO 17409.
4. Communication standards: ISO/IEC 15118-1, ISO/IEC 15118-2, ISO/IEC 15118-3, ISO/IEC 15118-4, IEC 61851-24, IEC 61850, ISO/IEC 15118-20.
5. General standards: IEC 61439-7, IEC 60038, IEC 61000-4-4, IEC 61000-4-5, IEC 61000-4-5, IEC 61000-4-11, IEC 61557-8, IEC 61000-6 -1. IEC 60529, IEC 60364-7-722.
Below we mainly sort out some requirements for DC charging.
