CCS1 vs CCS2: EV Charging Interface, Speed, Applicable Region Comparison Guide

Choosing the right fast charging connector can be confusing for many new EV owners. When people talk about CCS1 and CCS2, the names sound technical, but the idea behind them is simple: both are designed to charge electric vehicles quickly and safely. The difference mainly comes from where you live, what car you drive, and what kind of charging network is available around you. For drivers, understanding these standards matters because it affects how easily you can charge your car on a road trip or at a public ev charging station [https://www.pvpscs.com/products/].

For businesses planning to build charging sites, the decision is even more important. Picking the wrong connector can lead to low usage and higher costs. Many companies prefer flexible equipment that supports several standards so they can serve more vehicles in one location. A global ev charging solutions manufacturer [https://www.pvpscs.com/] needs to design hardware that works in different regions, from North America to Europe and Asia. In this guide, we will explain CCS1 and CCS2 in a simple way, compare their differences, and help you decide which standard fits your needs best.

What Is CCS and Why Does It Matter?

CCS stands for the Combined Charging System, and it matters because it defines how electric vehicles plug into fast-charging points. In simple terms, CCS combines both AC and DC charging in one connector and has become a key standard for public charging.

On a deeper level, CCS impacts three major areas. First, user experience: if your car supports the connector and the local network uses it, charging at a public station is seamless. Second, vehicle compatibility: manufacturers worldwide are aligning their models with CCS, so choosing the wrong connector means fewer charging options. Third, commercial deployment: charging-station operators and an EV charging station provider must plan infrastructure that supports the right standard or risk under-utilization and higher costs.

From a market perspective, the CCS segment alone generated USD 4,515.1 million in 2024 and is projected to grow to USD 21,345.5 million by 2030, reflecting a CAGR of about 30.3%.

Also, global fast-charger networks are expanding rapidly: for example, the global EV charging station market was valued at USD 39.7 billion in 2024 and is expected to keep growing strongly. gminsights.com

Because of these trends, CCS isn't just a technical detail-it's a critical choice for drivers, automakers, and infrastructure players alike.

What Is CCS1?

CCS1 (also known as Combo 1) is a fast-charging connector standard mainly used in North America and South Korea, combining both AC and DC charging in one plug.

Diving further, CCS1 is built on the legacy SAE J1772 (Type 1) AC connector and adds two extra DC pins for fast charging. According to one review, CCS1 supports DC charging up to approximately 350 kW, similar to other standards. In terms of regional use, CCS1 is dominant in the United States and South Korea, where it remains the "mainstream standard for non-Tesla EVs". For example, South Korea officially moved to adopt CCS as its fast-charging protocol some years ago.

In terms of vehicles, many North American EVs coming from major automakers support the CCS1 inlet, making it the expected connector at many public fast-charging stations. From an infrastructure standpoint, the US government's funding for EV charging networks requires multiple connector types, and CCS1 remains eligible under programs supporting public stations. Because of this wide network and compatibility, if you drive in North America and your car uses CCS1, you'll likely find plenty of fast-charging options available.

What Is CCS2?

CCS2 stands for the second version of the Combined Charging System connector, and it is the main fast-charging standard used across Europe, the Asia-Pacific region, the Middle East and Australia.

In more detail, CCS2 is built on the IEC Type 2 (or Mennekes) connector for AC charging and adds two large DC pins beneath it to handle high-power fast charging. The standard supports the same AC + DC flexibility as its counterpart, making it ideal for a wide variety of markets. Thanks to its compatibility and strong regulatory backing, CCS2 has become the dominant connector in many regions: for example, the DC fast-charging stations market report notes that CCS2 "emerged as the predominant standard in Europe and being mandated by the EU for EV charging networks."

Also, the broader market data shows that the combined charging system connector type captured about 40.07 % of the electric vehicle charging infrastructure market in 2024.

Because more car manufacturers and public-charging networks in multiple countries adopt CCS2, it offers better multi-national reach and interoperability. Governments across Europe are pushing deployment through policies like minimum fast-charger densities, which helps accelerate the rollout of CCS2 infrastructure.

Thus, if you operate across different countries or drive a globally sold EV model, CCS2 often offers the best compatibility and future-proofing.

CCS1 vsCCS2: Key Differences

When comparing the two standards-CCS1 and CCS2-it helps to focus on four major areas: connector design, charging power, vehicle compatibility, and infrastructure adoption. These differences shape how easily you can charge your EV and how well the charging network serves you.

Connector Design & Interface Layout

CCS1 extends the SAEJ1772 (Type1) AC connector by adding two DC pins beneath it, while CCS2 extends the IEC62196 Type2 connector with the same additional two DC pins.

The physical size is also different: CCS1 is generally bulkier, whereas CCS2 is more streamlined and supports threephase AC in certain markets.

Because CCS2 supports more pins and higher current/voltage configurations, it becomes more compatible with a wider regional standard and future upgrades.

Charging Power & Speed

Both standards support DC fast charging up to ~350kW or more in many cases.

However, in practical terms CCS2 has an edge: some sources show it supports up to 350amps or more current compared to approx. 200amps for CCS1, giving it greater headroom for highpower fast charging.

On the AC side, CCS2 supports both single and threephase charging (up to ~43kW) whereas CCS1 often covers only singlephase AC at lower power.

Vehicle Compatibility

In North America and South Korea, most nonTesla EVs use CCS1, while in Europe, AsiaPacific and Australia the dominant standard is CCS2.

Models sold in the U.S. such as the Chevrolet Bolt and Ford Mustang MachE are examples for CCS1 regions; while in Europe, vehicles like the Audi etron and Renault Zoe tend to adopt CCS2.

Because of this geographic split, your choice of EV connector matters a lot if you plan to travel or move between regions.

Infrastructure Adoption

The infrastructure for each standard mirrors their regional dominance. In North America, CCS1 stations are widespread, but global growth trends show CCS2 deployed more broadly in Europe and many parts of Asia.

Regulatory and policy support in Europe even mandates CCS2 compliance in EV charging networks under EU legislation.

Over time, this means CCS2 may offer better futureproofing and network density in many international markets, while CCS1 remains strong in its region.
