CCS stands for Combined Charging System. It is the dominant standard for rapid and ultra-rapid EV charging in the UK and across Europe, and every new electric car sold in the UK now uses it. If you are buying an EV, charging on public rapid networks or planning a longer journey, understanding how CCS works and what speeds to expect will help you get the most out of the charging infrastructure available to you.
Key Takeaways
- CCS (Combined Charging System) is the UK’s main rapid-charging connector, used by over 95% of rapid chargepoints on UK networks.
- The connector combines a standard Type 2 AC plug (top) with two additional DC power pins (bottom) for high-speed charging.
- CCS supports charging speeds from 50kW up to 350kW, depending on the charger and the vehicle’s onboard capability.
- A 50kW CCS charger adds approximately 75 miles of range in 30 minutes on a typical 60kWh battery; a 150kW charger can add around 225 miles in the same time.
- There are over 13,000 rapid and ultra-rapid CCS charge points live in the UK, with the network growing continuously.
What Does CCS Stand For?
CCS stands for Combined Charging System. The “combined” part refers to how the connector is designed: it uses the top section of a standard Type 2 AC connector — the seven-pin plug used for slower home and public AC charging — and adds two extra DC (direct current) power pins below it.
This two-part design means a single connector handles both AC and DC charging. The top portion connects for slower AC sessions; the full CCS plug (all pins engaged) connects for rapid DC sessions. The connector is large but well-designed, and the latch mechanism secures firmly during a charge session.
CCS vs Type 2: What Is the Difference?
It helps to understand CCS in relation to the Type 2 connector it builds upon:
| Connector | Current type | Max speed | Typical use |
|---|---|---|---|
| Type 2 | AC | Up to 22kW | Home charging, public AC posts |
| CCS (with DC pins) | DC | Up to 350kW | Public rapid and ultra-rapid chargers |
Your EV has a single combined port on the vehicle that accepts both connectors. For home charging and slower public posts, the Type 2 plug engages only the top portion of the port. At a rapid charger, the full CCS plug engages the entire port including the DC pins.
You do not need two different sockets on your car — the CCS port is designed to accommodate both.
How Fast Does CCS Charge?
CCS supports a wide range of charging speeds. What you actually experience depends on two things: the power output of the charger you are plugged into, and the maximum DC charging rate your vehicle accepts.
Charger Power Levels
| Charger tier | Power output | Common locations |
|---|---|---|
| Rapid | 50kW | Town centres, retail parks, older motorway hubs |
| High-power rapid | 100-150kW | Newer motorway hubs, Gridserve sites |
| Ultra-rapid | 150-350kW | Ionity hubs, Gridserve Electric Highway, Tesla Supercharger |
Real-World Range Added
| Charger power | Approximate range added in 30 minutes* |
|---|---|
| 50kW | ~75 miles |
| 100kW | ~150 miles |
| 150kW | ~225 miles |
| 350kW | Up to ~350 miles (vehicle limited) |

Your Vehicle’s Charging Limit Matters
A 350kW charger only delivers 350kW if your car can accept it. Most current EVs have onboard DC charging limits between 50kW and 270kW. Plugging a car rated for 100kW DC into a 350kW charger does not damage the car — the vehicle’s battery management system caps the draw at its own maximum rate. The charger’s headline figure is its ceiling, not its guaranteed delivery.
Why Does Charging Slow Down Above 80%?
If you have watched a charge session on your EV’s display, you will have noticed the charging rate slows significantly once the battery passes around 75-80% state of charge. This is intentional and is managed by the battery management system.
Lithium-ion batteries accept charge fastest when they have headroom. As the battery fills, the management system progressively reduces the incoming current to protect the cells from overheating and stress. Pushing a near-full battery at full rate accelerates cell degradation. The taper from 80% to 100% is slow by design.
For most public charging stops, stopping at 80% makes practical sense: you get the majority of the charge in the fastest part of the session, and the final 20% takes as long as the first 80%. Charge to 100% before longer journeys when you genuinely need the full range.
What Happens in Cold Weather?
Cold temperatures reduce a battery’s ability to accept charge. A battery that has been sitting in sub-zero temperatures overnight may only accept 30kW from a 150kW charger at the start of a session — the battery management system throttles the rate until the cells warm to their optimal operating range of roughly 15-35°C.
The practical result: cold-weather rapid charging sessions take longer than the published figures suggest, particularly at the start of the session. As the battery warms through charging, the rate typically increases.
The solution is battery preconditioning — heating the battery to operating temperature before arriving at a charger. Most modern EVs support scheduled preconditioning via their app. Some, like Tesla, automatically precondition the battery when you navigate to a Supercharger in the car’s map. Arriving at a rapid charger with a preconditioned battery means you benefit from full charging speed from the moment you plug in.
CCS vs CHAdeMO: Do You Need to Know the Difference?
CHAdeMO is an older DC rapid charging standard, predominantly associated with Nissan Leaf models (up to the 2022 generation) and some older Mitsubishi EVs. It uses a different, larger connector and a separate port on the vehicle.
In the UK, CHAdeMO is in decline. Many charging networks are removing CHAdeMO heads from their chargers as newer hardware is installed. If you drive a current-generation EV, you almost certainly use CCS. If you own an older Nissan Leaf with CHAdeMO, check that your planned charging locations still have CHAdeMO availability before relying on them — coverage is no longer guaranteed.
CCS in Practice: What to Expect at a Rapid Charger
When you arrive at a CCS rapid charger for the first time, the process is straightforward:
- Park adjacent to the charging unit and check the cable can comfortably reach your charge port.
- Initiate the session — most networks accept contactless bank card payment directly on the unit, or use an app or RFID card. Contactless is now mandated on all new rapid charger installations in the UK.
- Pick up the CCS cable — it is tethered to the unit; you do not need your own cable for DC charging.
- Open the CCS port cover on your car — on most EVs this is the lower, larger port.
- Insert the connector firmly until it clicks and locks. The car and charger handshake electronically to confirm compatibility and set the charge parameters.
- Charging begins — the car display or the charger unit shows the live rate and estimated completion time.
- Stop the session via the app, unit touchscreen or by unlocking your car (varies by network and vehicle).
- Unlatch and replace the cable.
The full process takes under a minute once you have done it a few times.

Frequently Asked Questions
What does CCS mean on an electric car? CCS stands for Combined Charging System. It is the connector used for rapid and ultra-rapid DC charging on virtually all new EVs sold in the UK. The connector combines a standard Type 2 AC plug (top) with two additional DC power pins (bottom), allowing one port on your car to handle both slow home charging and fast public rapid charging.
Is CCS the same as Type 2? No — though CCS builds on the Type 2 standard. A Type 2 plug is used for AC charging at speeds up to 22kW (home wallbox or public AC post). A CCS plug adds two DC pins below the Type 2 section for rapid DC charging at speeds from 50kW up to 350kW. Your car has a single port that accepts both.
How many miles does a CCS charger add per hour? It depends on the charger’s power output. A 50kW CCS charger adds approximately 150 miles of range per hour for a typical EV. A 150kW charger can add around 450 miles of range per hour, though in practice a 30-minute stop is most common. Your car’s maximum DC charging rate caps how fast it actually charges regardless of the charger’s power ceiling.
Can I use a CCS charger if my car has a CHAdeMO port? No. CCS and CHAdeMO are different physical connectors that are not interchangeable without an adapter. If your EV uses CHAdeMO (typically older Nissan Leaf models), you can only use CHAdeMO DC rapid chargers. Check network availability before travelling, as CHAdeMO coverage is declining.
Why does my charging speed slow down before the battery is full? This is normal behaviour managed by your car’s battery management system. Lithium-ion batteries accept charge fastest when they have capacity to absorb it. As the battery approaches 80%, the management system progressively reduces the incoming current to protect the cells. The final 20% of charge always takes longer than the first 80%.
