Yes, you can install a 22 kW charger at home — but only if two conditions line up. Your property needs a three-phase electricity supply, and your car needs an onboard charger that can accept 22 kW of AC power. Many homes fail the first test and most cars fail the second, so run both checks before you order anything. If either fails, an 11 kW or 7.4 kW charger will charge your car exactly as fast in practice.
Key Takeaways
- A home 22 kW charger needs a three-phase supply and a car that accepts 22 kW AC.
- Check the supply with your network operator and the car’s AC rating in its specification.
- If either check fails, 11 kW or 7.4 kW charges your car just as fast in practice.
- Use a licensed electrician for the dedicated circuit and any network-operator paperwork.
Check 1: does your home have three-phase power?
A 22 kW AC charger draws 32 A on each of three phases. On a single-phase supply that power level is simply not available to a home charger. Signs of a three-phase supply include a meter labelled three-phase and three linked main switches or service fuses where the supply enters the building. Your electricity supplier or network operator can confirm from your address, and a licensed electrician can confirm on site. If you only have single-phase, the network operator can often add three-phase, but it is their job, with their quote and timescale. Our single-phase vs three-phase guide explains how to read the signs.
Check 2: can your car actually use 22 kW?
The car’s onboard charger converts AC to DC and sets the ceiling. Many EVs are limited to 11 kW AC, and plenty manage 7.4 kW; a 22 kW wallbox connected to an 11 kW car still delivers 11 kW. Check the car’s specification for “AC charging” or “onboard charger” before paying for capacity the car cannot take. As a rough guide to what the numbers mean in time, see how long charging takes at 7 kW, 11 kW and 22 kW.
Check 3: the installation itself
- A 22 kW wallbox needs a dedicated three-phase circuit, installed and certified by a licensed electrician.
- The installer checks the supply capacity and may fit load management so the charger cannot overload the house.
- In the UK, the installer may need to notify the distribution network operator about a larger charge point; your installer handles this.
- If the property already has a 32 A three-phase industrial socket, a portable 22 kW charger can avoid new fixed wiring — the socket itself still needs an electrician’s check.
| Your situation | Sensible choice |
|---|---|
| Single-phase home | 7.4 kW wallbox; it covers overnight charging for most drivers |
| Three-phase home, car limited to 11 kW AC | 11 kW wallbox; a 22 kW unit adds nothing |
| Three-phase home, car accepts 22 kW AC | 22 kW wallbox makes sense, especially for daytime top-ups |
| Three-phase industrial socket already fitted | 22 kW portable charger with a CEE plug |
22 kW options from EVDANCE
The EV-ACT3204PE is a 22 kW three-phase wallbox with a tethered Type 2 cable, RFID and app control, and an IP66 rating for indoor or outdoor mounting. If a suitable industrial socket is already in place, the EV-ACS3205PE is a 22 kW three-phase portable charger with a CEE 32 A plug and Type 2 connector. Both deliver their full rating only on a three-phase supply feeding a car that can accept it.
Frequently Asked Questions
Is a 22 kW charger worth it for overnight charging?
For most drivers, no. Even a 7.4 kW charger adds roughly 10–20 miles of range per hour on Level 2 charging, which refills a typical day’s driving in a few hours. The 22 kW advantage shows in short daytime sessions, not overnight.
Can a 22 kW charger run on a single-phase supply?
It can usually be connected, but it will only deliver single-phase power — about 7.4 kW at most. You pay for capacity you cannot use until the supply is upgraded.
Do I need permission to install one?
You need a licensed electrician, and in some regions the network operator must be notified or approve larger installations. Your installer will know the local rule; in the UK, installations should follow the IET Code of Practice.
