New energy vehicle charging connector knowledge

China [CN]

As one of the necessary equipment for new energy vehicle charging, the charging connector is positively correlated with the development of new energy vehicles and the comprehensive promotion and popularization of charging facilities, so the quality of the charging gun also affects the quality of the charging facility to a certain extent, it can be said that the new energy vehicle charging gun is also very important. Many people may not know much about new energy vehicle charging guns, but have only heard of this term. Let's take a look at the relevant knowledge of new energy charging guns.

Discussion:. What is Electric vehicle Charging Connector?

In fact, it is the electric vehicle charging interface, which is the charging device connecting the charging station and the electric vehicle, and also the tool that transmits electricity from the power supply to the car battery, which is generally called the charging gun or charging plug, which refers to the device that is inserted into the car charging port to charge the power battery.

First of all, charging guns are divided into DC gun AC (Alternating Current) and DC (Direct Current). Ac guns, also known as slow charging guns, charge relatively slowly, generally taking several hours or even longer to fully charge the battery. It is mainly used for charging needs in homes or commercial places. Can effectively meet the market demand for electric vehicle charging.

Charging connector standards: AC charging gun has three main interfaces, type1, type2, GB/T, which can also be called American standard, European standard and national standard. What is more special is that Tesla has its own standard charging interface. Type1 (SAE J1772 interface) : mainly used in the United States and countries close to the United States (such as Japan, South Korea). It is suitable for both 120V and 240V charging voltages. Type2 (IEC 62196 interface) : It is the interface standard for new energy vehicles in Europe, and the rated voltage is generally 230V. GB/T (GB/T20234 national standard interface) : China stipulates that the charging interface of each brand of domestic production of new energy vehicles must meet the national standard GB/T20234, and the rated voltage is generally 220V household voltage.

Thank you for watching and we hope to continue to work together to achieve a win-win situation. Access to more consultation: https://www.omgevcable.com
