The EV-AC03201T shares its power under two ceilings: 43 kW combined across both connectors, and 22 kW for any single connector. One car alone can draw at most 22 kW. When two cars charge together, their combined draw cannot pass 43 kW — and each car’s own acceptance also counts.
Key Takeaways
- Two ceilings govern the station: 22 kW per connector and 43 kW combined.
- One car alone can never take more than 22 kW; 43 kW is a two-connector total.
- The combined ceiling only binds when two high-acceptance cars charge together.
- The moment-to-moment split rules are not published — confirm them in writing before your site plan relies on them.
Two Ceilings, Not One Big Number
The “43 kW” in the station’s name is a total, not a per-connector rating. A dual-connector station is one unit on one supply, built to serve two parking bays from one installation, as our guide to what a dual port EV charger is explains. Its two published limits do different jobs. The 22 kW per-connector ceiling caps what a single connector can deliver, however empty the other bay is. The 43 kW combined ceiling caps what the station as a whole can draw from the site supply. A session is always governed by whichever limit it reaches first.
The Arithmetic of the Ceilings
There is a third number in every session: the car’s own AC acceptance, set by its onboard charger. The scenarios below are worked examples from the two published ceilings and typical acceptance classes — simple addition, not a promise of how any one session splits.
| Who is plugged in | What the ceilings allow |
|---|---|
| One car that accepts 22 kW | 22 kW. The per-connector ceiling binds; the empty connector adds nothing. |
| One car that accepts 11 kW | 11 kW. The car binds, well under both ceilings. |
| Two cars accepting 11 kW and 22 kW | 33 kW combined — both cars get their full ask. |
| Two cars accepting 7.4 kW and 22 kW | 29.4 kW combined — both served in full. |
| Two cars that each accept 22 kW | Demand is 44 kW against a 43 kW ceiling, so the pair is trimmed to 43 combined. How the missing kilowatt is divided is not published (below). |
The pattern is clear: the combined ceiling only bites when two high-acceptance cars charge at once. In common pairings, each car is limited by its own onboard charger, and sharing costs nobody anything.
What the Listing Does Not Say: How the Split Is Decided
The published figures stop at the ceilings. They do not describe the rules the station follows moment to moment when the combined ceiling binds, and those rules are what an operator should confirm in writing or from the manual before relying on them:
- When one car tapers near full, does its unused share move to the other connector, or stay reserved?
- Is a second car guaranteed a minimum delivery, or can the first session hold its rate?
- Does the station divide evenly, by demand, or by arrival order when both cars want more than the total allows?
- Can the operator set the split or a lower combined limit from the platform, and does it survive a restart?
Behaviour is a specification like any other: if your site plan assumes one answer, get it in writing. The general principle — that sharing divides a supply rather than creating power — is the same one behind whether load balancing increases charging speed.
The Station Behind the Numbers
The EV-AC03201T is a floor-standing AC station with two Type 2 connectors, a 7-inch touchscreen, RFID access and an IP54 enclosure, and it lists OCPP 1.6J for platform operation. Where one bay is enough, the EV-ACT3204PE 22 kW wallbox serves a single car at the same per-car ceiling. The dual-connector design earns its place where two bays sit side by side — a workplace row, a hotel car park, a small public site — on one supply run.
Frequently Asked Questions
Can one car get the full 43 kW?
No. The per-connector ceiling is 22 kW, so a single car can draw at most 22 kW even with the other connector empty. The 43 kW figure is the combined total for both connectors together.
Is 43 kW shared the same as two separate 22 kW chargers?
Not quite. Two independent 22 kW chargers on separate supplies could draw 44 kW at once. The shared station caps the pair at 43 kW and does it from one installation and one supply, which is the cost and planning advantage.
If a second car plugs in, does my session stop?
No — the second session runs alongside yours. The only open question is how the combined ceiling is divided when both cars together want more than 43 kW — the behaviour to confirm in the manual or in writing.
