CCS Combo 2: The Complete Guide to EV Charging in

Charging electric vehicles via a connector CCS Combo 2 has become the de facto European standard for fast charging. This protocol combines alternating (AC) and direct current (DC) capabilities in one connector, allowing the battery to be charged both from a home outlet and from high-power stations. But how exactly does this system work? Why did manufacturers choose it? Tesla, Volkswagen and BMW? And what pitfalls await owners when switching to CCS Combo 2?

In this article we will analyze in detail the technical features of the standard and compare it with alternatives (for example, CHAdeMO or Tesla Supercharger), and also give practical recommendations on choosing charging equipment and adapters. We will pay special attention compatibility with domestic charging networks - a problem that many owners of imported electric cars face in 2026.

What is CCS Combo 2 and how does it work?

Abbreviation CCS stands for Combined Charging System (combined charging system). The number "2" in the title indicates connector type, used in Europe and Asia (common in the USA and Japan CCS Combo 1 with a different contact arrangement). The main advantage of the standard is its versatility: one connector supports:

• 🔌 Alternating Current (AC) - up to 43 kW (single-phase) or 22 kW (three-phase) for home and semi-public stations.
• ⚡ Direct current (DC) - up to 350 kW on ultra-fast charging (for example, Ionity or Fastned).
• 🔄 Backward compatibility with connector Type 2 (Mennekes) for AC charging.

Structurally CCS Combo 2 is a connector Type 2 with two additional contacts for DC (located below the main part). This allows one outlet to be used for all types of charging, simplifying the infrastructure. For example, at a station with CCS Combo 2 can be recharged as Tesla Model 3 (with adapter) and Hyundai Ioniq 5 without additional adapters.

It is important to understand that charging power depends not only on the connector, but also on:

• 🔋 On-board charger capabilities (for example, Renault Zoe limited to 22 kW on AC).
• ⚡ Charging station power (not every dispenser produces the promised 150+ kW).
• 🌡️ Battery temperatures — when overheating, the system automatically reduces the current.

Comparison of CCS Combo 2 with other charging standards

There are several competing standards on the market, and the choice between them often depends on the region and vehicle model. Let's look at the key differences:

Standard	Max. power (DC)	Distribution region	Tesla Compatible	Benefits	Disadvantages
CCS Combo 2	up to 350 kW	Europe, Asia, Australia	Yes (with adapter)	Versatile, high power, supports most brands	Expensive cables, not all stations support maximum power
CHAdeMO	up to 100 kW	Japan, old models	No	Simplicity of design, reliability	Outdated, low power, few new models
Tesla Supercharger	up to 250 kW	USA, Europe (open to other brands)	Yes (native)	High station density, optimized for Tesla	Paid access for non-Tesla, limited compatibility
GB/T (China)	up to 237 kW	China, some Asian markets	No	Cheap components, government support	Incompatible with European cars without an adapter

In 2026 CCS Combo 2 leads in Europe thanks to support from the EU: from 2027, all new charging stations must be equipped with this connector. However, in Russia the situation is different - many operators still use Type 2 (AC) or CHAdeMO, which creates problems for owners of modern electric vehicles.

If you are planning to buy an electric car, pay attention to charging infrastructure map in your region. For example, in Moscow and St. Petersburg CCS Combo 2 About 60% of stations are supported, while in small cities this figure can drop to 20%. Check compatibility through services like PlugShare or Chargemap.

Which electric vehicles support CCS Combo 2

List of models with CCS Combo 2 is constantly expanding, but there are key brands that initially relied on this standard:

• 🚗 Volkswagen Group: ID.3, ID.4, Audi e-tron, Porsche Taycan, Škoda Enyaq.
• ⚡ Hyundai/Kia: Ioniq 5, Ioniq 6, EV6, Kia Niro EV.
• 🔋 BMW: i4, iX, i7 (all models from 2021).
• 🏎️ Mercedes-Benz: EQS, EQE, EQC (updated versions).
• 🔌 Tesla: Model 3 and Model Y (from 2022 in Europe supplied with CCS Combo 2 instead of a proprietary connector).

However, there are exceptions. For example, Nissan Leaf (until 2023) and Mitsubishi Outlander PHEV use CHAdeMO, and some Chinese brands like BYD or Geely can be equipped GB/T. Always check the connector type in the technical specifications of your specific model.

Full list of models with CCS Combo 2 (2020–2026)

The current list of supported vehicles can be found on the website CharIN e.V. (consortium promoting the CCS standard). As of 2026, the database includes more than 200 models from 30 manufacturers.

If your EV was released before 2018, there's a good chance it doesn't support CCS Combo 2. In this case you will need:

1. Check the possibility of upgrading the on-board electronics (for example, Renault Zoe first generations, the connector can be replaced).
2. Use adapters (eg CHAdeMO-to-CCS, but they limit the power to 50 kW).
3. Navigate to the station with Type 2 (AC), albeit with a slower charging speed.

How to connect to a charging station with CCS Combo 2: step-by-step instructions

Charging process via CCS Combo 2 It seems simple, but in practice, owners are faced with nuances - from connector blocking to payment errors. Let's look at the connection algorithm:

Check the battery charge level (optimally 10–80% for fast charging)

Make sure the car connector and station cable are clean (dust/ice may block the contacts)

Prepare a payment method (card, operator application, RFID key fob)

Check out the station's tariffs (prices may differ by 2-3 times!)

-->

Step 1. Parking and preparation

Drive up to the station so that the car connector is on the side of the charging station. Please note that cables CCS Combo 2 often heavy (weight up to 8 kg) and short (3–5 m). At some stations (for example, Ionity) the cable may be fixed to the speaker - do not pull it by force!

Step 2. Authorization

Charging activation methods:

• 💳 Bank card - at new stations (for example, Fastned) just touch the card to the reader.
• 📱 Mobile application - popular with operators like GreenWay or PlugSurfing.
• 🔑 RFID card/key fob — issued upon registration with the provider (for example, E.ON Drive).

Step 3. Connect the cable

Take the connector CCS Combo 2 and insert it completely into the car socket until it clicks. A connection confirmation should appear on the display of the machine or station. Do not start charging if the indicator is red! This may indicate:

• 🔌 Cable or connector malfunction.
• 🔋 Battery overheating (you need to wait 5-10 minutes).
• 💰 Unpaid session (check your balance in the app).

Step 4: Start and Monitor Charging

After successful connection:

1. From the station screen or app, select the desired power (if available).
2. Monitor your charging speed in kW - it may drop as your battery fills.
3. Do not leave your vehicle unattended in public stations (risk of vandalism or disabling by other users).

Step 5: End your session

When charging is complete:

1. Stop the session in the application or at the station (otherwise you may continue to be charged for downtime).
2. Press the unlock button on the connector (on some models, e.g. Tesla, this is done through the car screen).
3. Carefully remove the cable - do not pull the cord, only the connector housing!

Typical problems when charging via CCS Combo 2 and their solutions

Even with proper connection, electric vehicle owners encounter errors. Let's look at the most common ones:

⚠️ Attention: If the station gives an error Communication Error or Vehicle Not Ready, in 90% of cases the problem lies in dirty contacts connector. Wipe them with a dry cloth and try again.

Error	Possible reason	Solution
Plug Locked	Mechanical blocking of the connector due to a power failure of the station	Reboot the station (power off/on) or contact support
Ground Fault	Problems with grounding a station or vehicle	Try a different station or check the grounding on your home network
Temperature Too High	Overheating of the cable or battery (especially when charging in the sun)	Wait 10–15 minutes or move the vehicle into the shade
Payment Failed	Problems with payment (card blocked, insufficient funds)	Check your balance or use another payment method
Low Power	Station limits power due to network congestion	Try charging at a different time or choose a different station

Particular attention should be paid winter exercises. At temperatures below -10°C, many electric vehicles automatically reduce charging power or block fast charging (DC) altogether. In this case:

• 🔥 Warm up the battery before charging (for example, after driving 5–10 km).
• ⏱️ Use AC charging (she is less sensitive to cold).
• 🏠 Charge in a warm garage, if possible.

Another common problem is protocol incompatibility. For example, some Chinese electric vehicles (e.g. BYD Atto 3) may not recognize European stations CCS Combo 2 due to software differences. In this case, updating the car's firmware or using an adapter will help.

How to set up a home charging station with CCS Combo 2

For electric vehicle owners home exercise - the most convenient and economical option. However, installing a station with CCS Combo 2 requires taking into account several factors:

1. Selecting the station type

Suitable for home use:

• 🔌 AC charging (Type 2) — power up to 22 kW (three-phase). Suitable for overnight charging.
• ⚡ DC charging (CCS Combo 2) — power from 25 kW. More expensive, but charges 2-3 times faster.

For most users, the optimal option is AC charging (for example, Wallbox Pulsar Plus or ABB Terra AC). It is cheaper, easier to install and covers daily charging needs of 30–50 kWh.

2. Electrical requirements

Before purchasing a station, check:

• 🔌 Availability of three-phase connection (for power over 7 kW).
• 📊 allocated power — for charging at 11 kW, at least 15 kW of reserve will be required.
• 🛡️ Overload protection (automatic machines, RCDs, difavtomats).

⚠️ Attention: If your home is connected to a power limited network (e.g. 5 kW), setting the charger to 11+ kW may result in power outage when using other devices at the same time. In this case, consider the option with smart charging (for example, Wallbox Commander 2), which regulates consumption.

3. Installation and connection

It is better to entrust the installation of the station to certified specialists, but the general algorithm is as follows:

1. Select a location for installation (protected from rain and snow).
2. Lay the cable from the panel to the installation site (cross-section of at least 6 mm² for 11 kW).
3. Install the machine and the RCD (for example, ABB F202 A-25/0.03 for 25 A).
4. Connect the station according to the diagram (usually included in the instructions).
5. Set up your management application (if supported).

4. Cost and payback

Prices for equipment and installation in 2026:

• 🔌 AC charging (7–22 kW): from 30,000 to 100,000 ₽.
• ⚡ DC charging (up to 50 kW): from 200,000 ₽.
• ⚡ Installation: from 15,000 to 50,000 ₽ (depending on the complexity of the connection).

The payback of the home station depends on the mileage. For example, with daily charging at 50 kWh and a tariff of 5 ₽/kWh (at home) versus 20 ₽/kWh (public station), the savings will be about 75,000 ₽ per year. Thus, AC charging will pay for itself in 1–2 years.

The future of CCS Combo 2: what to expect in 2026–2030

Standard CCS Combo 2 continues to evolve. The following changes are expected in the coming years:

1. Increased power

Already today stations are being tested at 500+ kW (for example, project Terra 360 from ABB). This will charge the battery to 80% in 5-10 minutes. However, such capacities will require:

• 🔋 Batteries with improved heat dissipation (for example, with liquid cooling).
• ⚡ Cables with active cooling (prototypes are already being developed).

2. Unification with Tesla Supercharger

In Europe Tesla is already opening its stations to other brands by installing adapters CCS Combo 2. By 2026, a complete transition to this standard is planned, which will increase the density of the charging network by 30–40%.

3. Wireless charging

Although CCS Combo 2 remains the main wire standard, they are developing in parallel induction systems (for example, WiTricity). However, their power is currently limited to 11 kW, which makes them unsuitable for fast charging.

4. Regulation in Russia

In 2026, Russia does not have a single standard for charging stations, but it is expected that CCS Combo 2 will become a priority thanks to:

• 🚗 Localization of electric vehicle production (for example, Moskvich 3e equipped with this connector).
• 💰 State subsidies for charging infrastructure (program until 2030).

However, for now, many operators continue to install stations with Type 2 (AC) or CHAdeMO, which creates problems for owners of modern models. Before buying an electric car, check charging infrastructure map in your region.

FAQ: Frequently asked questions about CCS Combo 2

Is it possible to charge a Tesla via CCS Combo 2 without an adapter?

Yes, but only models released for the European market after 2022 (eg Model 3 or Model Y). US vehicles are equipped with a connector Tesla Proprietary and require an adapter.

How much does it cost to charge at a public station with CCS Combo 2?

Tariffs vary from 12 to 30 ₽/kWh depending on the operator and region. For example:

• Fastned: ~18 ₽/kWh.
• E.ON Drive: ~22 ₽/kWh.
• City stations (Moscow, St. Petersburg): 12–15 ₽/kWh.

Additionally, you may be charged for connection time (for example, 50 RUB/min after 30 minutes of inactivity).

Is it possible to independently modify CHAdeMO for CCS Combo 2?

Technically possible, but not recommended. This requires replacing the connector, updating the on-board computer firmware, and may void the warranty. It is better to use an adapter (eg CHAdeMO-to-CCS from Setec), albeit with a power limit of up to 50 kW.

Why does charging through CCS Combo 2 slow down after 80%?

This is normal behavior of lithium-ion batteries. After 80% charge, the system automatically reduces the current to protect the battery from overheating and degradation. For example, on Hyundai Ioniq 5 the speed may drop from 150 kW to 50 kW.

What adapters are needed for charging in Russia?

Depending on the station you may need:

• Type 2 (Mennekes) → CCS Combo 2 — for connection to AC stations.
• CHAdeMO → CCS Combo 2 - if your car does not support CHAdeMO.
• Schuko → Type 2 — for charging from a regular outlet (power up to 2.3 kW).

Before purchasing an adapter, check its certification (must meet IEC 61851).
