CCS2 (Combined Charging System / Combo 2) is the standard DC fast-charging socket in Turkey and Europe. With two powerful DC pins added below the Type 2 socket, it transfers high-power direct current, so the vehicle charges significantly in minutes compared with AC charging. It takes the name "combined" from this: the same connector supports both AC (the Type 2 part on top) and DC charging through a single socket, so the vehicle only needs one charging inlet. In DC charging the current conversion is done inside the station rather than in the vehicle, so power is delivered directly to the vehicle's battery and is not limited by the onboard charger. CCS2 is the common standard for Turkey's public fast-charging networks and new-generation electric vehicles. Bemis's in-house manufactured BEVDC series fast chargers (40–200 kW DC) use the CCS2 connector. In a typical scenario a roadside CCS2 station charges the car substantially during a short break on a long journey, while the same socket provides fast charging during a shopping trip in a mall car park. That is why CCS2 is a solution suited to situations that need speed away from home, complementing overnight AC charging at home.
The difference between Type 2 (AC only, 7 pins) and CCS2/Combo 2 (the same 7 pins + 2 DC pins): with CCS2 the same socket does both AC and DC fast charging.
Frequently Asked Questions
Why is CCS2 called "combined"?
CCS2 supports both AC (the Type 2 part on top) and DC charging in a single connector, thanks to two powerful DC pins added below the Type 2 socket; that is where the name comes from. This means the vehicle only needs one charging inlet and the driver does not need separate sockets.
Why is CCS2 faster than AC charging?
In CCS2 the current conversion is done inside the station rather than in the vehicle, so power is delivered directly to the battery and is not limited by the vehicle's onboard charger. As a result the car charges significantly in minutes compared with AC. Bemis's BEVDC series (40–200 kW DC) uses the CCS2 connector.
Is CCS2 the standard in Turkey?
Yes, CCS2 is the common standard for Turkey's public fast-charging networks and new-generation electric vehicles. A roadside CCS2 station charges the car during a short break on a long trip, while the same socket provides fast charging during a shopping trip in a mall car park.
