type1 type2 GB/T EV charging plugs difference

 EV Charging plug interface standards are roughly divided into 3 categories: one is the American standard, the other is the European standard and GB/T. According to the charging technology, they are divided into direct current charging (DC) standard and alternating current charging (AC) standard. DC plugs are high-current, high-power charging EV connectors. They are generally equipped in fast-charging stations for new energy vehicles. They have high voltage and fast charging speed.  AC charging plugs are used for home or portable charging,which charging speed is relatively slow.


1. AC charger

There are three main types, type1, type2 and GB/T, which can also be called American standard, European standard and China national standard. Of course, Tesla has its own standard charging connectors, but due to pressure, Tesla also began to change its standards according to market conditions to make its cars more suitable for the market.


①Type1:SAE J1772

Basically, the United States and countries closely related to the United States (such as Japan and South Korea) use Type 1 American standard charging plugs, including portable charging plugs carried by AC charging station in EV cars. Therefore, in order to adapt to this standard charging interface, Tesla also has to provide a charging plug adapter so that Tesla vehicles can use public charging point with Type 1 EV charger.

Type1 provides two main charging voltages: 120V (Level1) and 240V (Level2).


②Type2: IEC 62196

Type2 is the EV car interface standard in Europe, and the rated voltage is generally 230V. The picture may look a bit like the China national standard, but it is actually easy to tell the difference. The European standard is similar to the engraving, and the black part is hollow, which is the opposite of the China national standard.


③GB/T: GB/T20234 China national standard interface

From January 1, 2016, China stipulates that the charging interfaces of all brands of new energy vehicles produced domestically must comply with the standard GB/T20234. The rated voltage of the national standard AC charger is generally 220V household voltage.


2. DC charging plugs

DC charging plugs generally correspond to AC charging plugs. Each region has its own standards, with the exception of Japan. Japan’s DC charging connector is CHAdeMO. Of course, not all Japanese cars use this DC charging connector. Only some Mitsubishi and Nissan’s new energy models use the following CHAdeMO DC charging connector.

Others are American standard Type1 corresponding to CCS1, mainly adding a pair of high-current charging holes at the bottom.

The European standard Type2 corresponds to CCS2, which is similar to the American standard in that it combines a DC charging plug and an AC charging plug.
