What are the Types of EV Charging Connectors?

Currently, there are 6 EV charging connectors, J1772, CCS, CHAdeMo, GB/T, NACS and CHAoJi.

1) J1772:

J1772 is also called SAE J1772 or J plug. It is a North American standard for charging connectors for electric vehicles. It is developed and maintained by SAE International formerly known as the Society of Automotive Engineers.

There are two variants of this connector J1772 type 1 and type 2.

2) CCS:

Combined Charging Systems (CCS) are mainly designed for DC charging but they also support AC charging. There is just the addition of 2 extra pins in the J1772 connector makes it a CCS or Combo connector.

There are two variants of this connector: Type 1 or CCS1 and Type 2 or CCS2, respectively as of J1772 variants.

CCS standard was developed by SAE in collaboration between US and German automakers.

3) CHAdeMo:

CHAdeMo – a short form of ‘CHArge de MOve’ means ‘Charge for Moving’. Also a pun for ‘O cha demo ikaga desuka’ in Japanese. It means ‘Let’s have a cup of tea while charging’.

It was developed by five major Japanese automakers and the Tokyo Electric Power Company forming the CHAdeMo association.

4) GB/T:

GB/T charging standard was developed in China and published by China Electricity Council (CEC). It is mainly used in China.

5) NACS:

North American Charging Standard (NACS) is developed by Tesla, Inc. It is also called Tesla charging standard.

It is currently being standardized as SAEJ3400 and is probably going to be adopted by major auto manufacturers in the future.

6) ChaoJi

China Electricity Council (CEC) and CHAdeMO working together to develop a new standard ‘ChaoJi’ also called CHAdeMO 3.0. It is currently under development.
