For a car that can actually accept 22 kW of three-phase AC power, the EV-ACT3204PE puts roughly 20 kWh into the battery per hour once charging losses are counted. That makes the everyday 20–80% charge about 1.2 hours for a 40 kWh battery and about 3 hours for a 100 kWh one. A full charge takes longer than the same division suggests, because every car slows down near full — plan around the 20–80% numbers.
Key Takeaways
- At a sustained 22 kW with losses counted, about 20 kWh reaches the battery per hour.
- The 20–80% charge takes about 1.2 hours (40 kWh) to about 3 hours (100 kWh).
- Full-charge division gives a floor, never the finish: the car tapers near full.
- Every figure assumes a car that accepts 22 kW three-phase — check yours first.
Where the 22 kW Rate Actually Holds
On AC charging, the wallbox offers power and the car converts it. This wallbox’s offer is 22 kW: 32 A on each of three phases, on a 380–400 V supply. A car whose onboard charger is rated for 22 kW three-phase can take that offer through the middle of its battery — roughly the 20–80% band — and that is the assumption behind every figure below. Near full, the car tapers: it asks for less, and the wallbox delivers less, whatever its rating says.
The condition matters more than the arithmetic. Most cars accept 11 kW of AC power, or about 7 kW on a single phase, and charge at their own rate on this wallbox — the 11 kW and 7 kW times, not these. Our explainer on single-phase vs three-phase charging shows where each figure comes from, and our comparison of charging time at 7 kW, 11 kW and 22 kW covers the lower ratings. This article is for the cars that can take the full rate.
The Times, Battery by Battery
All figures are worked examples at a sustained 22 kW with about 10% allowed for losses, so about 20 kWh reaches the battery per hour. The last column divides the whole battery by the same rate: read it as the floor a full charge cannot beat, not the time it will take.
| Battery size | 20–80% adds | Time at a sustained 22 kW | 0–100% by the same division (the floor) |
|---|---|---|---|
| 40 kWh | 24 kWh | About 1.2 hours | About 2 hours |
| 60 kWh | 36 kWh | About 1.8 hours | About 3 hours |
| 80 kWh | 48 kWh | About 2.4 hours | About 4 hours |
| 100 kWh | 60 kWh | About 3 hours | About 5 hours |
Why a Full Charge Always Beats the Division
The taper is the reason. Through the middle of the battery, a 22 kW-capable car holds close to the full rate and the arithmetic holds with it. In the last stretch — broadly above 80% — the car steadily reduces what it accepts, so the final fifth of the battery takes a share of time well beyond its share of energy. Two practical consequences follow. First, schedule your day around the 20–80% column: it is the part of the charge that behaves predictably. Second, charge to 100% when a long trip actually needs it, and expect that session to run past the floor in the table — how far past depends on the car.
The EV-ACT3204PE as the 22 kW Example
The EV-ACT3204PE is EVDANCE’s 22 kW wallbox: a hardwired three-phase unit (32 A, 380–400 V) with a tethered Type 2 cable, RFID and app control, an IP66 rating and CE marking. On a three-phase supply, feeding a car that accepts 22 kW, it holds the rate this article’s table assumes. On any other car it delivers that car’s rate instead — which is why the buying question comes first, as our piece on 11 kW vs 22 kW wallboxes sets out from the stocking side.
Frequently Asked Questions
How long does a 75 kWh car take on this wallbox?
If the car accepts the full 22 kW: the 20–80% band adds 45 kWh, so about 2.3 hours. A full charge divides to a floor of about 3.8 hours and will run longer in practice, because the car tapers near full.
Does the wallbox hold 22 kW all the way to 100%?
No. The wallbox keeps offering 22 kW; the car decides what to take, and every car reduces its intake near a full battery. The sustained rate belongs to the middle of the battery.
My car accepts 11 kW. Are these my times?
No — your car charges at 11 kW on this wallbox, so roughly double the 20–80% times here. The figures in our 7 kW, 11 kW and 22 kW charging time comparison are the ones to plan with.
