CCS, CHAdeMO, GB/T & Tesla: How EV Charging Differs?

February 26, 2025

With the rise of electric vehicles (EVs) worldwide, understanding different EV charging standards helps both EV owners and businesses make informed choices. Charging compatibility, speed, and infrastructure availability vary significantly depending on the standard. In this guide, we compare CCS, CHAdeMO, GB/T, and Tesla Supercharger, highlighting their differences and explaining how they impact EV users and charging infrastructure worldwide.

Understanding EV Charging Standards

CCS (Combined Charging System)

CCS is one of the most widely used EV charging standards, particularly in North America and Europe. It integrates AC and DC charging into a single plug, making it versatile and efficient.

Key Features: CCS1 (North America) and CCS2 (Europe) versions
Maximum Power Output: Up to 350 kW with CCS2
Compatible EVs: Volkswagen, BMW, Ford, Hyundai, Rivian, and many others
Pros: High-speed charging, growing infrastructure, and future-proof design
Cons: Limited adoption in Asia, requires larger plug size

CHAdeMO

Developed in Japan, CHAdeMO was one of the earliest EV charging standards to support DC fast charging. Its main advantage is bidirectional charging, enabling vehicle-to-grid (V2G) technology.

Key Features: Used primarily in Japan, some adoption in Europe and the US
Maximum Power Output: Up to 100 kW (next-gen allows 400 kW)
Compatible EVs: Nissan LEAF, Mitsubishi Outlander PHEV, Kia Soul EV
Pros: Supports V2G, stable infrastructure in Japan
Cons: Slower charging speeds compared to CCS, decreasing global adoption

GB/T (China National Standard)

China enforces GB/T as the official EV charging standard, making it the dominant choice in the world’s largest EV market. Unlike CCS, China separates AC and DC plugs.

Key Features: AC and DC charging use different connectors
Maximum Power Output: Up to 250 kW (higher in future updates)
Compatible EVs: Almost all Chinese EVs
Pros: Government-backed, extensive infrastructure in China
Cons: Incompatible with non-Chinese EVs, limited adoption outside China

Tesla Supercharger

Tesla introduced the Supercharger, a high-speed charging solution designed for convenience and efficiency. Tesla has started integrating CCS compatibility in certain regions.

Key Features: Proprietary connector, shifting to CCS in some markets
Maximum Power Output: Up to 250 kW (V3 Supercharger), V4 expected to exceed 300 kW
Compatible EVs: Tesla vehicles (Supercharger access expanding for non-Tesla EVs in some locations)
Pros: Reliable and fast charging, extensive Supercharger network
Cons: Limited access for non-Tesla EVs (depending on location)

Key Differences Between Charging Standards

Plug Design & Compatibility

Each EV charging standard has a distinct connector design, which affects interoperability. Tesla’s proprietary plug is transitioning to CCS in some areas, while GB/T remains exclusive to China.

Charging Speed & Power Output

Tayniu offers chargers that support CCS and Type 2 charging, providing a practical solution for EV owners. Learn more here. Speed is a crucial factor. While CCS and Tesla Superchargers offer high-power fast charging, CHAdeMO lags behind, and GB/T is catching up.

Standard	Max Power Output	Regions Used	Compatibility
CCS	Up to 350 kW	North America, Europe	Most modern EVs
CHAdeMO	Up to 100 kW (future 400 kW)	Japan, some US/EU	Nissan, Mitsubishi
GB/T	Up to 250 kW	China	Chinese EVs
Tesla	Up to 250+ kW	Global	Mostly Tesla (some CCS support)

Market Adoption & Regional Preferences

North America & Europe: CCS is the dominant standard
Japan: CHAdeMO remains the primary option
China: GB/T is mandatory
Tesla: Supercharger network expanding, adopting CCS in some markets

Infrastructure & Availability

Charging infrastructure plays a significant role in accessibility. CCS and Tesla Superchargers have the widest coverage outside China, while GB/T dominates within China.

Future Trends & Standardization Efforts

The EV industry is gradually shifting towards universal compatibility, with Tesla opening its Supercharger network and CHAdeMO declining in favor of CCS. Emerging technologies like megawatt charging for heavy-duty EVs may further reshape the landscape.
