Choosing the right EV connector is essential for safe, efficient, and reliable electric vehicle charging. Different regions, vehicle manufacturers, and charging networks use different connector standards, which directly affect charging compatibility, power delivery, and charging experience.
The most common EV charging connector types worldwide include Type 1, Type 2, CCS, GB/T, CHAdeMO, and Tesla/NACS connectors. Each standard has been developed for specific markets and charging applications, from residential charging to commercial and public charging infrastructure.
In this guide, we will explain the major EV connector types, their differences, regional applications, and how to choose the right connector for your electric vehicle or charging project.
What Is an EV Connector?
An EV connector is the plug interface used to transfer electrical power between an electric vehicle and a charging station. It connects the vehicle charging port with an EV charger through a charging cable, allowing electricity to safely flow into the vehicle battery.
Unlike traditional fuel systems, EV charging uses different connector standards depending on:
- Vehicle manufacturer
- Regional charging regulations
- Charging infrastructure requirements
- AC or DC charging applications
- Power output requirements
Selecting the correct EV connector ensures charging compatibility, safety, and optimal charging performance.
Types of EV Charging Connectors
Different countries and regions have developed their own EV charging standards based on local automotive industries, regulations, and infrastructure requirements. 1
The main EV charging connector types include:
- Type 1 (SAE J1772)
- Type 2 (Mennekes)
- CCS (Combined Charging System)
- CHAdeMO
- GB/T
- Tesla NACS
Type 1 EV Connector (SAE J1772)
The Type 1 connector, also known as the SAE J1772 connector, is mainly used in North America and Japan 2.
It is designed primarily for AC charging applications, including Level 1 and Level 2 charging. The connector uses a five-pin design that supports power delivery and communication between the EV and charging equipment.
Key Features:
- Commonly used in North America and Japan
- Designed for AC charging
- Supports single-phase charging
- Widely adopted by Japanese and American EV models
Type 1 connectors are commonly found in residential charging applications where vehicles are charged overnight or parked for extended periods.
Type 2 EV Connector (Mennekes)
The Type 2 connector, also known as the Mennekes connector, is the standard AC charging connector widely used in Europe and many other regions.
It supports both single-phase and three-phase AC charging 3, making it suitable for residential charging, workplace charging, commercial applications, and public charging stations.
Key Features:
- Standard connector for Europe
- Supports AC charging up to higher power levels
- Compatible with single-phase and three-phase charging
- Used widely in residential and commercial EV charging
For European EV charging infrastructure, Type 2 has become the dominant connector standard.
BESEN provides Type 2 EV charging cables and AC charging solutions designed for residential, commercial, and workplace charging applications.
GB/T EV Connector (China Charging Standard)
The GB/T connector is the EV charging standard developed and widely used in China. It covers both AC charging and DC fast charging applications and is commonly found in Chinese electric vehicles and charging infrastructure.
Unlike Type 1 and Type 2 connectors, GB/T uses its own charging communication protocol and connector design, making it different from most international charging standards.
Key Features:
- Standard used primarily in China
- Supports both AC and DC charging
- Widely adopted by Chinese EV manufacturers
- Designed for compatibility with China’s charging infrastructure
With the rapid growth of China’s electric vehicle market, GB/T has become one of the world’s most widely deployed EV charging standards.
CCS Connector (Combined Charging System)
The Combined Charging System (CCS) is a fast-charging standard that combines AC charging capability with additional DC charging pins.
There are two main versions:
- CCS1: Based on Type 1 connector, mainly used in North America
- CCS2: Based on Type 2 connector, widely used in Europe
CCS connectors are mainly used for DC fast charging and can support significantly higher charging power compared with traditional AC charging.
Key Features:
- Supports high-power DC charging
- Widely adopted by global EV manufacturers
- Common in public fast-charging networks
While CCS is mainly associated with fast charging infrastructure, Type 2 remains the common choice for everyday AC charging applications.
CHAdeMO Connector
CHAdeMO is a DC fast-charging connector originally developed in Japan.
It was widely adopted by early Japanese electric vehicles, including models from Nissan and Mitsubishi. However, in many markets, CCS has become the preferred standard for new DC fast-charging deployments.
Key Features:
- Designed for DC fast charging
- Common in earlier Japanese EV models
- Supported by some existing charging networks
CHAdeMO remains in use, but its market share has declined as CCS adoption continues globally.
Tesla Connector (NACS)
Tesla uses its own charging connector, known as the North American Charging Standard (NACS).
Originally developed for Tesla vehicles, NACS has gained increasing attention in North America as more manufacturers consider adoption.
Key Features:
- Compact connector design
- Supports both AC and DC charging
- Increasing adoption in North America
EV owners should always confirm vehicle compatibility before selecting charging equipment or adapters.
EV Connector Standards Around The World
Different markets typically use different EV charging connector standards.
| Region | Common EV Connector Standards |
|---|---|
| Europe | Type 2, CCS2 |
| North America | Type 1, CCS1, NACS |
| China | GB/T |
| Japan | Type 1, CHAdeMO |
| Global DC Fast Charging | CCS, CHAdeMO, NACS |
Understanding regional standards is important for EV charger manufacturers, installers, and charging infrastructure providers when selecting suitable equipment.
Type 1 vs Type 2 EV Connector: What Is The Difference?
Type 1 and Type 2 are two of the most common AC charging connectors worldwide. The main differences are related to region, connector design, and charging capability.
| Feature | Type 1 | Type 2 |
|---|---|---|
| Main Market | North America & Japan | Europe & many global markets |
| Charging Type | AC charging | AC charging |
| Phase | Single-phase | Single & three-phase |
| Pins | 5 pins | 7 pins |
| Common Applications | Residential charging | Residential, workplace, commercial charging |
For most European EV charging applications, Type 2 is the preferred connector due to wider vehicle compatibility and support for higher AC charging power.
AC vs DC Charging Connectors
EV connectors can also be classified based on charging methods.
