Today, AG is going to introduce the standard of charging cable in detail.
Let’s go with a very intuitive picture first.
Firstly, the charging cable is divided into DC cable and AC cable. DC cable: high current and high-power charging cable is generally equipped in the fast charging station of new energy vehicles. Household are generally AC charging piles or portable charging cable.
1. AC charger is mainly divided into three types: Type1, Type2 and GB / T, which can also be called American Standard, European standard and Chinese standard. Of course, Tesla has its own standard charging interface, but under pressure, Tesla also began to change its standards according to the market situation to make it car more suitable for the market, just as Chinese Tesla must be equipped with a Chinese standard charging port.
① Type 1: SAE j1772 interface, also known as j-plug, basically uses type 1 American standard charging cable in the United States and countries closely related to the United States (such as Japan and South Korea), including the portable charging cable carried by the AC charging pile. Therefore, in order to adapt to this standard charging interface, Tesla has to provide a charging cable adapter so that Tesla cars can use the public charging pile of the type charging port. Type 1 mainly provides 120V (level1) and 240V (level2) charging voltages
② Type 2: IEC 62196 interface
Type 2 is the interface standard for electric vehicles in Europe, and the rated voltage is generally 230V. Looking at the picture may be a bit like the Chinese standard. In fact, it is easy to distinguish. The European standard is similar to the male engraving, and the black part is hollowed out, which is opposite to the national standard.
② GB / T: GB / T 20234 Chinese standard interface since January 1, 2016, China stipulates that the charging interface of all brands of new energy vehicles produced in China must comply with the Chinese standard GB /T 20234. Therefore, the adaptation of the charging interface to the national standard does not need to be considered for new energy vehicles produced in China after 2016, because the standard has been unified. The rated voltage of national standard AC charger is generally 220V household voltage.
2. DC charging cable
DC charging cable generally correspond to AC chargingcable. Each region has its own standards, with some exceptions in Japan. The DC charging cable interface in Japan is chademo. Of course, not all Japanese cars use this DC charging interface. Only some new energy models of Mitsubishi and Nissan use the chademo DC charging port below.
Others are American Standard type 1 corresponding to ccs1: mainly by adding a pair of high current charging holes below.
European standard type1 corresponds to CCS2:
Chinese standard DC charging standard:
The rated voltage of DC charging pile is generally above 400V and the current reaches hundreds of AMPS, so it is generally not household, and it can only be used in fast charging stations set up in shopping malls and gas stations.
