Yes, in one direction. CCS1 (Combined Charging System, Type 1) is a J1772 connector with two large DC pins added below it. A car with a CCS1 inlet accepts a normal J1772 plug in the upper part for AC Level 2 charging, and the full CCS1 plug for DC fast charging. A J1772-only car cannot use DC fast charging, and a CCS1 plug will not fit a J1772-only inlet.
Connector Family
| Connector | AC | DC | Main regions |
|---|---|---|---|
| J1772 (Type 1) | Yes | No | North America, Japan |
| CCS1 | Via J1772 section | Yes | North America |
| Type 2 | Yes | No | Europe, UK, Australia |
| CCS2 | Via Type 2 section | Yes | Europe, UK, Australia |
| NACS (J3400) | Yes | Yes | North America |
| CHAdeMO | No | Yes | Japan, older models |
Is J1772 the Same as CCS?
No. J1772 is AC only; CCS1 combines J1772 with DC pins. Federal NEVI rules require funded DC fast ports to have at least one permanently attached CCS Type 1 connector and AC ports to have a J1772 connector.
Adapters
For NACS-port cars at CCS1 fast chargers, or CCS1 cars at NACS fast chargers, use only automaker-approved DC adapters. EVDANCE makes the EVDANCE JT08 NACS-to-CCS1 adapter and EVDANCE JT09 NACS-to-CCS1 adapter with handle NACS-to-CCS1 adapters; check your car maker’s approved list before use. See are EV charging adapters safe.
