22kW AC Charger Guide
A 22 kW AC charge point can deliver high-power three-phase AC, but the car's onboard charger—not just the post—sets the charging speed.
How 22 kW AC charging works
AC chargers supply power that is converted to DC inside the vehicle. A 22 kW charge point generally needs a suitable three-phase supply and Type 2 cable. If a car supports only 7 kW or 11 kW AC, its charging rate will be capped at that lower level.
Benefits and considerations
- Faster AC charging for vehicles equipped with a 22 kW onboard charger.
- Useful at destinations where a vehicle is parked for a few hours.
- Can serve as shared charging infrastructure for compatible fleets.
- Check three-phase availability and the vehicle's AC charging limit.
Example charging times
10% to 80% on a 60 kWh usable battery adds 42 kWh. Times assume ideal constant power without losses.
| Vehicle AC limit | Effective power | Ideal time |
|---|---|---|
| 22 kW capable vehicle | 22 kW | 1.9 hours |
| 11 kW capable vehicle | 11 kW | 3.8 hours |
| 7 kW capable vehicle | 7 kW | 6 hours |
22kW AC charger FAQs
No. The vehicle's onboard charger may be limited to a lower rate such as 7 kW or 11 kW.
On a 60 kWh battery, the ideal time is 1.9 hours only if the vehicle can accept 22 kW. At 11 kW, it is about 3.8 hours before losses.
Type 2 is common for AC charging across the UK and Europe.
