EV charger connector detailed description.

First of all, EV charger connectors are divided into DC and AC. DC is high-current, high-power chargers, which are generally equipped in EV fast charging stations. Home use is generally an AC charger, or a portable charger.

  1. AC connector

There are mainly three types, type1, type2, GB/T, which can also be called American standard, European standard and national standard. Of course, Tesla has its own standard charging interface, but under pressure, Tesla also began to change its own standards depending on the market situation to make its cars more suitable for the market, just like domestic Teslas must be equipped with national standard charging mouth.

①Type1: SAE J1772 interface, also known as J-plug

Basically, the United States and countries with close ties to the United States (such as Japan and South Korea) use Type 1 American standard charging guns, including portable charging guns carried by AC charging piles. Therefore, in order to adapt to this standard charging interface, Tesla also had to provide a charging gun adapter so that Tesla cars can use the public charging pile of the Type1 charging port.

Type1 provides mainly two charging voltages, 120V (Level1) and 240V (Level2).

②Type2: IEC 62196 interface

Type2 is the EV interface standard in Europe, and the rated voltage is generally 230V. Looking at the picture, it may be a bit similar to GB. In fact, it is easy to distinguish. The black part is hollowed out, which is the opposite of GB.

③GB/T: GB/T20234 national standard interface

From January 1, 2016, my country stipulates that as long as the charging ports of all brands of EVs produced in China must comply with the national standard GB/T20234, so domestic EVs produced after 2016 do not need to consider whether the charging port is suitable for GB problem, because the standard has been unified.

The rated voltage of GB AC charger is generally 220V household voltage.

  1. DC connector

The DC connector generally corresponds to the AC charging gun, and each region has its own standards, with the exception of Japan. The DC charging port in Japan is CHAdeMO. Of course, not all Japanese cars use this DC charging port, and only some new energy vehicles from Mitsubishi and Nissan use the following CHAdeMO DC charging port.

Others are American Standard Type1 corresponding to CCS1: mainly add a pair of high-current charging holes below.

European standard Type2 corresponds to CCS2:

And of course our own DC charging standard:

The rated voltage of DC chargers is generally above 400V, and the current reaches several hundred amperes, so generally speaking, it is not for household use. It is only possible to use fast charging stations such as shopping malls and gas stations.
