Decoding Electric Vehicle Charger Pins: Understanding the Variations Between Type 1 and Type 2

The charging terminal pin is an important interface for power transmission and communication between new energy automotive and charging equipment, and it plays a role in power transmission, charging control, communication transmission, and security protection. Generally speaking, with the charging pin, people can replenish their new energy automotive.

Exploring the Different Types of Charger Pins for Electric Vehicle

According to different charging rules, charging terminals can be divided into GB/T terminals, SAE terminals, IECterminals,NACSterminals, According to different current, charging terminals can be divided into AC terminals and DC terminals. Different standards and currents combine to form a variety of specifications of charging terminals. 

In a charging device such as an AC charging plug, different charging terminals play different roles, such as CP(control confirmation) terminal, CC (charge link confirmation) terminal, PE (ground protection) terminal, L (AC power supply) terminal, N (neutral wire) terminal, their diameter and tail cable size are different. And in order to facilitate the link of the charging device, the terminals are divided into male and female terminals.

In addition, in the design structure, in order to meet different customer needs, the same standard charging terminals can also have a variety of structures, such as leaf spring terminals, crown band terminals, rotate contact terminals, ring core terminals, torsion spring terminals, O spring terminals, etc.

The Difference between Type1 and Type2 Charger Pins

1. The difference between the standard and the market:

Type1 follows the SAE J1772 Combo standard, which is mainly used in the North American and Japanese markets, the five holes of the J1772/Type 1 AC charging port are: L1: AC charging phase line 1; N: AC charging N line; PE: Protective earth, protective earth; CP: Control pilot; PP: Proximity Pilot. Type2 follows the IEC 62196 standard and is mainly used in the European market. The seven holes of the AC charging port of Type2 are L1/L2/L3, N, CP, PP, PE

2. The difference between current and voltage:

The rated voltage of Type 1 interface is single-phase 250V,32A; The rated voltage of the Type 2 interface is 250V for single phase and 480V for three phase. The rated current of single-phase charging is 13A, 20A, 32A, 63A and 70A several recommended specifications, and the rated current of three-phase charging is 13A, 20A, 32A and 63A several recommended specifications.

Conclusion

The Charging pin is a key component in a charging device that transmits electrical energy. It is usually made of copper and its alloys, has a specific shape and size, and can be tightly connected to the charging interface to ensure the efficient transmission of electrical energy. Type1 Charger Pins, generally with high compatibility and stability, can meet the needs of most traditional car charging. In the early construction of electric vehicle charging infrastructure, the Type1 charging pin laid the foundation for the popularity of electric vehicles.

The Type2 Charger Pins represent a more advanced and efficient charging technology. Compared with Type1, Type2 charging pins usually have higher charging power and faster charging speed, which can meet the needs of modern vehicles for fast charging. With the continuous progress of electric vehicle technology and the increasing perfection of charging facilities, Type2 charging pins are more and more widely used in the automotive industry and have become an important force to promote the development of the electric vehicle industry.
