The main connection standards for DC fast charging of electric vehicle charging connectors in the world include:

CCS (Combined Charging System): widely used in North America and Europe, with strong compatibility, supporting AC and DC charging, and is the mainstream choice of many brands.

CHAdeMO: mainly used in Japan and some Asian countries, supports bidirectional charging (V2X), allowing electric vehicles to power homes or power grids.

GB/T: China's national standard, widely used in domestic charging networks to ensure compatibility of local electric vehicles.

Tesla Supercharger: Tesla's proprietary fast charging standard, with high charging efficiency and gradually compatible with the CCS standard to improve charging flexibility.

These standards adapt to the needs of different regions and brands, promoting the diversification of global charging infrastructure.
