There are currently six major EV charging connector standards in global use — and choosing between them determines which vehicles you can charge, which charging networks you can access, and how future-proof your infrastructure investment is.
For charging station operators, fleet managers, automotive engineers, and industrial designers building EV charging hardware, understanding these standards is not optional. This guide covers every major standard, their regional adoption, and how to select the right connector for your application.
The Six Major EV Charging Connector Standards
Type 1 — SAE J1772 (AC Charging, North America and Japan)
What it is: The North American and Japanese standard for AC charging. A 5-pin connector supporting single-phase AC power.
Charging speed: Up to 19.2 kW (Level 2, single-phase)
Voltage/Current: Up to 240V AC / 80A
Regions: North America, Japan
Vehicle compatibility: Most non-Tesla North American EVs (2010–2024), Japanese EVs
Key detail: Type 1 handles Level 1 (120V) and Level 2 (240V) AC charging only. For DC fast charging, vehicles using Type 1 for AC add two DC pins below the AC connector — this combined form is called CCS1.
Type 2 — Mennekes (AC Charging, Europe)
What it is: The European standard for AC charging (IEC 62196 Type 2). A 7-pin connector supporting both single-phase and three-phase AC power.
Charging speed: Up to 22 kW (three-phase, 32A) for standard charging; up to 43 kW with high-power AC chargers
Voltage/Current: Up to 400V three-phase AC / 32A (standard), 63A (high-power)
Regions: Europe (mandatory for all new public AC chargers in EU)
Vehicle compatibility: All European EVs, Tesla (Europe)
Key detail: Type 2 supports three-phase charging, which is standard in European electrical infrastructure. This gives European EV owners faster home and workplace charging speeds compared to single-phase Type 1.
CCS1 — Combined Charging System Type 1 (DC Fast Charging, North America)
What it is: CCS1 combines the Type 1 AC connector with two additional DC pins below it. This allows both AC and DC charging through a single port, eliminating the need for a separate DC fast charging inlet.
Charging speed: Up to 350 kW DC fast charging
Voltage/Current: Up to 1000V DC / 500A
Regions: North America, South Korea
Vehicle compatibility: Most non-Tesla North American EVs (2012–2024)
Transition note: As of 2025, Ford, Hyundai, Kia, BMW, Toyota, and Rivian have switched new North American models to NACS (see below). CCS1 remains on pre-2025 vehicles and will require adapters to access expanding NACS networks.
CCS2 — Combined Charging System Type 2 (DC Fast Charging, Europe)
What it is: The European DC fast charging standard, combining Type 2 AC pins with two DC pins. Mandatory for all new DC fast charging stations in the EU.
Charging speed: Up to 360 kW
Voltage/Current: Up to 1000V DC / 500A
Regions: Europe, Australia, South Africa
Vehicle compatibility: All European EVs, Tesla (Europe, via CCS2 port)
CHAdeMO (DC Fast Charging, Japan)
What it is: Developed by Japanese automakers (Toyota, Nissan, Mitsubishi, Subaru, Honda), CHAdeMO was one of the first DC fast charging standards and includes native vehicle-to-grid (V2G) bidirectional charging capability.
Charging speed: Up to 400 kW (CHAdeMO 3.0 / ChaoJi)
Voltage/Current: Up to 1000V DC / 400A
Regions: Japan (dominant), limited presence in Europe and North America
Vehicle compatibility: Nissan Leaf (North America uses CHAdeMO only for DC), legacy Mitsubishi, some Toyota models
Market status: CHAdeMO is declining in North America and Europe. Many charging networks are phasing out CHAdeMO stalls. Japanese automakers are transitioning new models to CCS for North American and European markets. CHAdeMO remains the dominant standard in Japan.
NACS — North American Charging Standard / SAE J3400
What it is: Originally Tesla’s proprietary connector, opened to other manufacturers in 2022 and standardized as SAE J3400. Roughly half the size of CCS1 while handling both AC and DC charging through the same port.
Charging speed: Up to 250 kW at Tesla Superchargers; infrastructure supports higher
Voltage/Current: Up to 1000V DC / 400A
Regions: North America (rapidly becoming dominant)
Vehicle compatibility: All Tesla (US), Ford/Hyundai/Kia/BMW/Toyota/Rivian (2025+ models)
Why NACS is winning in North America:
- Smaller, lighter plug (approximately half the size and weight of CCS1)
- Single port for both AC and DC charging
- Access to Tesla Supercharger network (the largest fast charging network in the US)
- Major automaker adoption completed in 2025
GB/T — Chinese National Standard
What it is: China’s national EV charging standard, covering both AC (GB/T 20234.2) and DC (GB/T 20234.3) charging. Required for all EVs sold in China.
DC charging speed: Up to 250 kW (current standard); ChaoJi (next-generation) targets 900 kW+
Regions: China (mandatory)
Vehicle compatibility: BYD, NIO, Xpeng, Li Auto, Tesla (China-market models), all Chinese EVs
Key detail: GB/T connectors are not compatible with CCS or NACS without an adapter. Chinese EVs exported to European or North American markets typically include CCS or NACS inlets alongside or instead of GB/T.

For Infrastructure Developers and Hardware Engineers
Connector IP Ratings for Charging Equipment
EV charging connectors used in public infrastructure must meet ingress protection requirements defined by relevant standards (IEC 62196, SAE J1772, SAE J3400):
- Indoor residential chargers: IP44 minimum
- Outdoor public charging stations: IP55 minimum (most manufacturers specify IP67)
- High-exposure public locations: IP67 or higher recommended
Cable inlet connectors (the vehicle-side socket) on EVs are typically rated IP54 with cap installed, IP44 without. The charging connector (station side) is typically rated IP54 when unmated.
Liquid-Cooled Cables for High-Power Applications
CCS and CHAdeMO stations delivering more than 200A require liquid-cooled charging cables. The cooling system runs coolant through the cable to manage heat generated by high-current transmission, allowing a thinner, more flexible cable at power levels that would otherwise require impractically heavy copper cables.
This applies to:
- CCS1 and CCS2 stations above approximately 150 kW
- CHAdeMO stations above 100 kW
- Any station delivering continuous 200A+
Frequently Asked Questions
–What is the difference between CCS1 and CCS2?
CCS1 is used in North America and combines a Type 1 AC connector (single-phase) with two DC pins. CCS2 is used in Europe and combines a Type 2 AC connector (three-phase) with two DC pins. Both use the same DC charging communication protocol and similar power levels, but they are not physically compatible with each other.
– Is NACS replacing CCS in North America?
Yes, for new vehicles. Starting in 2025, most major automakers selling in North America have switched new models to NACS (SAE J3400). CCS1 remains on pre-2025 vehicles and will require adapters to use NACS charging infrastructure. Both connector types will coexist in North American infrastructure for the next decade.
–Can a CHAdeMO vehicle use CCS charging stations?
Not natively. CHAdeMO and CCS use different physical connectors and different communication protocols. Adapters exist in some markets (notably CHAdeMO-to-CCS2 in Europe), but availability varies. For new vehicles, the practical answer is to transition to a CCS or NACS vehicle for broader charging compatibility.
–What EV charging connector standard should I use for a new charging station in Europe?
New public charging stations in Europe are required by EU regulation to support CCS2 (Combined Charging System Type 2) for DC fast charging and Type 2 (Mennekes) for AC charging. CHAdeMO support is optional but declining in relevance for new installations.
–What is the difference between Type 2 and CCS2?
Type 2 (Mennekes) is the European AC charging connector — it handles single-phase and three-phase AC charging up to 22 kW (or 43 kW with high-power AC chargers). CCS2 adds two DC pins below the Type 2 connector to enable DC fast charging. A vehicle with a CCS2 port can use both Type 2 AC chargers and CCS2 DC fast chargers through the same inlet.
