There are several main types of EV connectors, depending on the region and charging level:

Type 1 (SAE J1772): Common in North America for AC charging

Type 2 (IEC 62196): Standard in Europe for AC charging

CCS1 & CCS2 (Combined Charging System): Used for DC fast charging in North America (CCS1) and Europe (CCS2)

CHAdeMO is a protocol for DC fast charging, predominantly adopted by several Asian electric vehicle manufacturers.

GB/T: The standard in China, with separate AC and DC connectors

Selecting the appropriate connector type hinges on the specific model of your electric vehicle and the charging network available in your area.
