EV Plug Type – CCS Type 1 (SAE J1772-2009)

Type 1 cables (SAE J1772, J Plug) are used to charge EV produced for North America, South Korea and Japan with alternating single-phase current. Due to its slow charging speed, it was replaced by the Combined Charging System (CCS) Combo Type 1 (SAE J1772-2009).

CCS Type 1 Combo (J1772)

Almost all modern electric vehicles have an improved version, the CCS Combo Type 1, which allows charging from high-power DC circuits also known as rapid of fast chargers.

CCS Combo Type 1 Specifications

Connector CCS Type 1 supports AC charging up to 80A. The use of a cable with cooling at the direct charge allows to achieve a charge of 500A if your EV supports it.

CCS Type 1 vs Type 2 Comparison

The two connectors are very similar on the outside, but once you see them together, the difference becomes obvious. CCS1 (and its predecessor, Type 1) have a completely circular top, while CCS2 has no upper circle segment. The CCS1 is also characterized by the presence of a clamp on the top of the connector, whereas CCS2 has only an opening and the clamp itself is mounted on the car.

CCS Type 1 vs CCS Type 2 comparison

The key difference in the technical characteristics of the connectors is that it is not possible to work with three-phase AC power grids via the CCS Type 1 cable.

Which Cars use CSS Combo Type 1 for Charging?

As mentioned earlier, CCS Type 1 is more common in North America and Japan. Therefore, this list of automobile manufacturers establishes them serially in their electric vehicles and PHEVs produced for this region:

  • Audi e-Tron;
  • BMW (i3, i3s, i8 models);
  • Mercedes-Benz (EQ, EQC, EQV, EQA);
  • FCA (Fiat, Chrysler, Maserati, Alfa-Romeo, Jeep, Dodge);
  • Ford (Mustang Mach-E, Focus Electric, Fusion);
  • Kia (Niro EV, Soul EV);
  • Hyundai (Ioniq, Kona EV);
  • VW (e-Golf, Passat);
  • Honda e;
  • Mazda MX-30;
  • Chevrolet Bolt, Spark EV;
  • Jaguar I-Pace;
  • Porsche Taycan, Macan EV.

CCS Type 1 to Type 2 Adapter

If you export a car from the United States (or another region where the CCS Type 1 is common), you will have a problem with charging stations. Most of the EU is covered by charging stations with CCS Type 2 connectors.

CCS Type 1 to CCS Type 2 Adapter

The owners of such cars have few options for charging:

  • Charge EV at home, through the outlet and the factory power unit, which is very slow.
  • Rearrange the connector from the European version of EV (for example, the Chevrolet Bolt is ideally fitted with an Opel Ampera socket).
  • Use CCS Type 1 to Type 2 Adapter.

Can Tesla use CCS Type 1?

There is no way to charge your Tesla S or X via CCS Combo Type 1 for now. You only can use adapter to Type 1 connector, but the charging speed will be awful.

What adapters should I buy for Type 2 charging?

We strongly discourage the purchase of cheap basement devices, as this could lead to a fire or damage to your electric car. Popular and proven models of adapters:

  • DUOSIDA EVSE CCS Combo 1 Adapter CCS 1 to CCS 2;
  • Charge U Type 1 to Type 2;
