Running several dual-connector stations on one supply starts with an honest split. Inside one EV-AC03201T, the two connectors share up to 43 kW with dynamic allocation, as the listing states. Between several stations, the listing specifies no built-in load management — so sites use three routes instead: size the supply for the combined ceiling, stagger use through operations, or confirm platform-level management in writing before purchase. This article works through all three.
Key Takeaways
- Dynamic allocation is stated between one station’s two connectors — not between stations.
- Size for the combined ceiling (stations × 43 kW), stagger by operation, or confirm platform management in writing.
- Supply sizing is a licensed electrician’s load assessment, not a listing figure.
- An unstated feature is a question to close before purchase, never a planning assumption.
What the Listing States — and What It Does Not
The stated facts are the ceilings and the connection. One EV-AC03201T delivers up to 43 kW shared across its two Type 2 connectors (22 kW per connector), allocates that power dynamically between the two connectors, and connects to a back-office platform over OCPP 1.6J. The listing does not state that stations balance load between each other, and it names no smart-charging profiles. Treating an unstated feature as present is how sites end up with a supply that only works on paper — the building load calculation basics make the same point for fixed installations.
Route One: Size the Supply for the Combined Ceiling
The conservative route needs no features at all: the supply is assessed for the worst case, every connector on every station drawing at once. The arithmetic is simple multiplication of the station ceiling — labelled here as planning figures, before any diversity judgement an electrician may apply.
| Stations on one supply | Connectors | Combined ceiling if all draw at once |
|---|---|---|
| 1 | 2 | 43 kW |
| 2 | 4 | 86 kW |
| 3 | 6 | 129 kW |
| 4 | 8 | 172 kW |
Whether the site actually needs that full figure is a load assessment, and it belongs to a licensed electrician or site engineer working from the building’s existing demand — not to a product page. Cars also rarely draw their maximum for a whole session, but “rarely” is an observation, not a design basis.
Route Two: Stagger by Operation
Where dwell times are long — workplaces, depots, residential car parks — the operator can spread demand without any electronics: rota rules, booked windows, or simply enough connectors that cars finish at different times. Staggering is an operating practice, not a guarantee; it fails on the one evening everyone plugs in at once, which is why it pairs with route one rather than replacing it. Our explainer on whether load balancing increases charging speed covers what sharing does to an individual session.
Route Three: Ask the Platform Question in Writing
The third route is a question, not an assumption. The station’s stated OCPP 1.6J connection is the path a platform would use to manage a group of stations — but whether a given platform can cap a group, and whether this station accepts such control, is not stated in the listing. Before relying on it, get written confirmation covering: group power caps across several stations, what happens to a session when the cap changes, and behaviour if the platform connection drops. If the answer is no, routes one and two are the plan.
The Station in This Example
The EV-AC03201T is a floor-standing AC station with two Type 2 connectors, up to 43 kW shared (22 kW per connector, dynamically allocated), a 7-inch touchscreen, RFID access, OCPP 1.6J, and an IP54 enclosure. Plan multi-station sites on those stated facts — and on written answers for everything beyond them. See also EVDANCE’s commercial charging solutions.
Frequently Asked Questions
Do several EV-AC03201T stations balance load between themselves automatically?
The listing does not say so. It states dynamic allocation between the two connectors of one station, and an OCPP 1.6J platform connection. Station-to-station balancing is a written-confirmation question for EVDANCE and the platform provider, before purchase.
How much supply capacity do four stations need?
At the stated ceilings, four stations total 172 kW if every connector draws at once. Whether your site must provide all of it is a load assessment by a licensed electrician, based on the building’s demand and how the site is used — not a figure a product listing can set.
Does sharing 43 kW between two connectors make charging slow?
Each connector keeps a 22 kW ceiling, and the pair shares 43 kW, so two cars charging together can each run near a connector’s full rate; what a specific car receives also depends on the car’s own acceptance. Sharing is a ceiling question, not a fault.
