In the UK and much of Europe, a “rapid” charger usually means a DC charger of roughly 50 kW or more, and “ultra-rapid” means about 100–150 kW and above. “Fast” usually refers to AC chargers of 7–22 kW, and “slow” to lower-power AC charging. These labels are common industry terms rather than strict legal definitions, and some sources draw the boundaries slightly differently.
Common UK and US Terms
| UK term | Typical power | Rough US equivalent |
|---|---|---|
| Slow | Up to about 7 kW AC | Level 1 and lower Level 2 |
| Fast | 7–22 kW AC | Level 2 |
| Rapid | About 50 kW DC and above | DC fast charging |
| Ultra-rapid | About 100–150 kW DC and above | High-power DC fast charging |
Connectors
UK and European rapid chargers use CCS2 (and older units CHAdeMO). AC “fast” chargers use Type 2, often socketed. See CCS connectors explained.
Where Each Fits
- Fast AC: homes, workplaces, hotels; for example the EVDANCE EV-ACT3204E 22 kW wallbox (22 kW) or the dual-gun EVDANCE EV-AC03201T dual-gun AC charging station.
- Rapid DC: retail, depots and short stops; compact units like the EVDANCE EV-RHDC30K-L compact DC fast charger.
- Ultra-rapid: motorway service areas and hubs.

Frequently Asked Questions
Is a 22 kW charger rapid?
No, 22 kW AC is usually called fast; rapid usually means DC around 50 kW and up.
How long does a rapid charger take?
Often 30–60 minutes from about 20% to 80%, depending on the car.
Is rapid the same as Level 3?
Roughly; both refer to DC fast charging.
