Your speed on the EV-AC03201T is the lowest of three numbers: what your car can accept, the 22 kW ceiling of the connector, and your share of the station’s 43 kW combined total. Most cars accept 11 kW of AC or less, so for most drivers a second car on the other connector changes nothing at all. Only two cars that both accept 22 kW ever meet the shared ceiling.
Key Takeaways
- Your speed is the lowest of: your car’s acceptance, the 22 kW connector ceiling, and your share of 43 kW.
- Cars accepting 11 kW or less are never slowed by the second connector.
- Only two 22 kW cars together reach the combined ceiling, and the exact split is not published.
- A late-session fade is usually your car’s taper, not sharing.
Three Numbers Decide Your Speed
The first number is yours. AC charging speed is set by the car’s onboard charger, and acceptance classes are well established — our explainer of single-phase vs three-phase charging walks through the 7 kW, 11 kW and 22 kW classes. The second number is the connector’s: no connector on this station delivers more than 22 kW. The third is the station’s combined ceiling of 43 kW, which matters only when the two cars’ demands together would pass it. Your delivered rate is whichever of the three is smallest at that moment.
What Each Car Class Gets
The table is labelled arithmetic from those three numbers, assuming each car asks for its full acceptance. It describes ceilings, not a published splitting rule — the station’s exact division when the combined ceiling binds is a manual question.
| Your car’s AC acceptance | Alone on the station | Both connectors in use |
|---|---|---|
| 22 kW (three-phase) | 22 kW | Up to 22 kW. Alongside another 22 kW car, the pair is capped at 43 kW combined — an even division would be about 21.5 kW each, shown as arithmetic, not as a promised split. |
| 11 kW | 11 kW | 11 kW. Even with a 22 kW car beside you, combined demand is 33 kW, under the ceiling. |
| 7.4 kW (single-phase) | 7.4 kW | 7.4 kW. Sharing never comes into it at this level. |
| About 3.6 kW | About 3.6 kW | About 3.6 kW. Your onboard charger is the only limit in play. |
The practical reading: sharing on an AC station is a narrow event. It needs two cars, at the same time, both able to accept more than 21.5 kW — a small slice of today’s car park, and a slice that matters less than drivers expect, because of what happens inside the session.
Why Your Rate Still Moves During a Session
A falling rate is not automatically the other car’s fault. Every EV slows its charging as the battery approaches full — the taper — and that is the car’s decision, not the station’s. The timing is the tell. A rate that steps down in the first minutes after a second car starts is the shared ceiling at work. A rate that fades gradually as your percentage climbs is your battery. Knowing which one you are watching stops a normal session being reported as a fault, which is why operators who understand how a dual port charger works field fewer complaints about it.
What to Tell Drivers
For operators, the honest wording is “up to 22 kW per car”. A sign or app note that promises 22 kW flat sets an expectation the combined ceiling cannot always meet; one that says “43 kW shared between two cars” tells the truth and matches what the station’s screen can show. The EV-AC03201T itself is a floor-standing station with two Type 2 connectors, a 7-inch touchscreen, RFID access, an IP54 enclosure and OCPP 1.6J for platform operation — one installation covering two bays, which is why its speeds are worth explaining to drivers before they ask.
Frequently Asked Questions
Will two cars always charge at about 21.5 kW each?
No. That figure is only the arithmetic of two 22 kW cars meeting the 43 kW combined ceiling. Most cars accept less and are unaffected, and the station’s exact division at the ceiling is not a published figure.
Does the second car slow down a car that accepts 7.4 kW?
No. A 7.4 kW car plus even a 22 kW car totals 29.4 kW, well under 43 kW. Your rate stays at your car’s own limit.
How long does 40 kWh take at these speeds?
As steady-rate arithmetic: about 2 hours at 22 kW, and roughly 4 hours at 11 kW. Real sessions run longer towards the end, because the car tapers as it fills — allow for that in any plan.
