Only if the charger’s own written specification says it accepts a single-phase supply — and even then it cannot deliver 22 kW from one phase. “22 kW” is a three-phase rating: the power is shared across three phases at once. Where the maker states no single-phase rating, treat the unit as three-phase only. For a single-phase home, the practical answers are a charger rated for single phase, or a supply upgrade.
Key Takeaways
- 22 kW is a three-phase rating; one phase cannot deliver it.
- The charger’s written specification — a stated single-phase mode or none — decides what may be connected.
- No EVDANCE 22 kW unit states a single-phase rating; treat it as three-phase only.
- Single-phase homes choose a single-phase-rated charger, or apply for a three-phase supply.
What the “22 kW” Rating Actually Describes
A 22 kW AC charger draws about 32 A on each of three phases simultaneously. Take two phases away and the arithmetic collapses: one phase at 32 A is the roughly 7 kW class that single-phase 32 A chargers are sold as. The U.S. DOT puts Level 2 charging at 7–19 kW, adding about 10–20 miles of range per hour, and a single-phase charger sits in the lower half of that band. Our explainer on single-phase vs three-phase EV charging works through the same numbers. The supply type is part of what the product is, not a detail to negotiate at installation.
The Written Specification Is the Deciding Document
Some manufacturers do state a single-phase connection mode for a three-phase-rated unit, with a lower output figure for that mode. Others state three-phase only. That sentence in the manual — not the headline power on the box — decides what your electrician may connect.
| What to check | Where it is stated | What it settles |
|---|---|---|
| Supply type | The rating plate and the manual’s electrical specification | Whether single-phase connection is contemplated at all |
| Single-phase mode, if any | The manual’s installation section | The output in that mode — the maker’s figure, not a guess |
| Input current per phase | The specification table | The circuit the electrician must design, at 125% under the NEC continuous-load rule |
| Warranty and listing conditions | The manual and warranty terms | Both follow the stated instructions — an off-spec connection puts them at risk |
If no single-phase mode is stated, do not assume one exists, and do not let anyone improvise one. Ask the manufacturer in writing before ordering, or choose a unit whose rating matches your supply in the first place. The car is a second gate: even with three phases available, its onboard charger sets its own ceiling, as our guide to charging times at 7 kW, 11 kW and 22 kW shows.
The Two Practical Routes for a Single-Phase Home
- Fit a charger rated for single phase. Single-phase units run from the roughly 7 kW class up to 48 A wall chargers in the 11.5 kW class — all inside the DOT Level 2 band, and all enough to refill a typical day’s driving overnight.
- Upgrade the supply to three-phase. That is the network operator’s or utility’s work: an application, their assessment, their quote and timetable. Your electrician handles only the house side. Whether your panel has room for the circuit is a separate check — see what size charger your panel capacity allows.
Single-Phase Options From EVDANCE
The EV-ACT3204PE is a 22 kW three-phase wallbox (tethered Type 2 cable, RFID and app, IP66, CE). Its page states no single-phase rating, so plan it for three-phase sites only and get written confirmation from us before ordering it for anything else. For single-phase homes, the EV-ACT5006T is a wall charger of up to 48 A (hard-wired or NEMA 14-50P, NACS, IP65/IP66, ETL/FCC/CE), and the EV-ACS3210E is a 32 A Type 2 portable charger, single-phase at about 7 kW, IP66. Both are rated for the supply a single-phase home actually has. See the residential charging range for the rest.
Frequently Asked Questions
Will a 22 kW charger just run more slowly on single phase?
Only where its maker states a single-phase mode, and then at the maker’s figure for that mode — around the 7 kW class at 32 A, not 22 kW. Where no mode is stated, there is nothing to “just run”.
Can my electrician convert my home to three-phase?
The supply itself is the operator’s equipment and decision. Your electrician can prepare the house side and help with the application, but the service, quote and timetable come from the operator.
Is 7 kW enough for overnight charging?
For most drivers, yes. Level 2 adds about 10–20 miles of range per hour on DOT figures, so an overnight park returns far more than a typical day’s driving uses.
