EV Charging Interface

Common EV charging standards (AC)

SAE J1772: Also known as a J plug or Type 1 connector after its international standard, it is widely used in North America, Japan, and Korea. And IEC 62196-2 also known as Type 2 connector. Type 2 connector is widely used in Europe and other regions. The GB/T charging standard is a set of GB/T standards, primarily in the GB/T 20234 family. The standards were revised and updated most recently in 2015 by the Standardization Administration of China.

Common EV charging standards (DC)

CCS1 chargers are primarily found in North and Central America, and Korea, while CCS2 can be found in Europe, South America, South Africa, Arabia, India, Singapore, Oceania, and Australia. The competing standard GB/T 20234-2015 is used in China, while Japan uses CHAdeMO.

The ChaoJi connector, also referenced as CHAdeMO 3.0, is an ultra-high-power charging standard charging electric cars, released in 2020. The design incorporates backward compatibility with CHAdeMO and the GB/T DC charging, using a dedicated inlet adapter for each system. The circuit interface of ChaoJi is also designed to be fully compatible with the Combined Charging System.

NACS charging standards (both AC and DC)

NACS is The North American Charging Standard (NACS), currently being standardized as SAE J3400, is an electric vehicle charging connector system developed by Tesla, Inc. The NACS standard can support both AC charging and DC fast charging. It has been used on all North American market Tesla vehicles since 2012 and was opened for use to other manufacturers in 2022.
