1. Introduce AC charging interface terminals

With the popularity of new energy vehicles, AC charging interface is gradually known by the public as a new type of charging equipment. Ac charging interface terminal is an important part connecting electric vehicle and charging pile, it is the main channel of electric energy transmission. According to the regulations, the AC charging interface should have the versatility to be used on different charging piles to ensure the smooth charging process.

2.the classification of AC charging interface terminals

According to the international standard IEC 62196, AC charging interface terminals can be divided into three different types, namely Type1, Type2 and CHAdeMO. They have their own characteristics and are suitable for different types of vehicles and scenarios.

① Type1

Type1 Charging interface terminal, also known as "Japanese standard", is a charging interface developed by Japanese electric vehicle manufacturers. It uses J1772 plugs and 5 pins to connect electric vehicles and charging piles, supporting AC charging and fast charging. Because this charging interface terminal is used earlier, relatively few models are adapted.

②Type2

Type2 Charging interface terminal is a charging interface designed by the European Union, also known as "European standard". It uses advanced electronic chip technology to support AC charging and fast charging of various powers. At present, most electric vehicles support the Type2 charging interface, which has become the main charging standard in Europe.

③ CHAdeMO

CHAdeMO is a DC charging interface developed in Japan that uses two additional large plugs to provide high power DC charging. Unlike Type1 and Type2, CHAdeMO is primarily used for fast charging, fully charging electric vehicles in a short amount of time. CHAdeMO is now widely used in Japan, North America and some countries in Europe.

3.the naming specification and difference of AC charging interface terminals

In the industry standard, Type1, Type2, and CHAdeMO all have a set of strict naming conventions for easy identification and annotation. Among them, the naming conventions of Type1 and Type2 are similar, both of which use "IEC62196-2" to represent standards and requirements, but the specific names are different. The Type1 designation is SAE J1772, and Type2 is often referred to as the Mennekes charging plug. CHAdeMO, on the other hand, uses the name itself as a naming standard.

4. Summary

Ac charging interface terminal is an important part of modern electric vehicles, and is also the core component of the connection between charging pile and electric vehicles. We can choose different types of charging interfaces to charge according to different models and charging piles. Although the three charging interfaces of Type1, Type2 and CHAdeMO have their own characteristics, they are all universal charging interfaces developed according to international standards.
