HARTING e-Mobility Charging Cables
OPTIMAL CONNECTIVITY offers charging cable assemblies for e-mobility. The most commonly used connector types are available from stock. Currently, there at least 9 different connector types defined as regional standards. Today’s electric cars are charged either with AC or DC power.
DC charging allows the car to be charged significantly faster than AC charging with 50 kWh, 150 kWh, whereas 270 kWh and 350 kWh chargers are emerging, which is reflected in the constant need to develop more efficient charging cables and connectors.
The different connector types are explained below:
Type 1 plug (also known as J1772) is capable to transfer up to 19.2 kW, which has become the standard for all American EVs. The Type 1 connector allows only the use of a single phase and it doesn’t support a built-in automatic locking system.
Type 2 connectors are found in European cars and have the advantage of using three phases according to specifications IEC 62196 as European standard. As Type 1 and Type 2 use the same J1772 signaling protocol for communication, passive adapters can be used among these types. The Type 2 plug supports a built-in automatic locking system.
Tesla Model S and Model X use Type 2 plug fitting to any AC charging station.
GB / T is the only connector model for charging stations and cars. The connector looks like to be the same as Type 2, but the cables inside are arranged in reverse order so they are not compatible.
CCS Type 1 and Type 2 (Combined Charging System), is the best solution for fast DC charging. Coming from either Type 1 or Type 2 designs, two more pins are added at the bottom. The CCS connectors can withstand power load of up to 350 kW.
When using the CHAdeMO connector, the car must always have two sockets.
CHAdeMO is the original DC plug developed by Japanese car manufacturers with little market coverage. New designs shall be capable to handle up to 400 kW and evenup to 900 kW.
CHAdeMO and GB / T charging stations are using different communication protocols than Type 1 and Type 2, so special adapters are needed.
GB / T China has its own standards for DC charging.
Tesla has a different connector design where Tesla cars can be charged at Tesla charging stations. Tesla offers adapters for other types of plugs like Type 1 or CHAdeMO plug.
