Laying out a bay for a single-connector DC charger is a short list of decisions: which side of the bay the station stands on, how a driver approaches it, whether the connector and the LCD can be reached and read from a seated position, and how the bay stays a working charging bay rather than a parking space. The binding requirements are set locally and differ by place, so confirm them with the local authority or an accessibility adviser. This article works through the decisions for the EV-RHDC30K-L; it states no standard and no dimensions, because none applies everywhere.
Key Takeaways
- Accessible layout is a decision process, not a set of universal dimensions; confirm local requirements in writing.
- One connector serving one bay removes the sharing question and replaces it with station side and waiting position.
- Confirm the cable length and connector weight in writing — the listing states neither.
- Marking and the operator’s policy keep a short-session DC bay available for charging, not parking.
What a Single DC Connector Changes
A dual-connector station raises a sharing question — which connector serves which bay, and whether one car’s cable crosses the other car’s space. A single-connector unit removes that question: one station, one bay. In its place come two decisions of its own. The first is the station’s side: it should stand where the driver transfers out of the car, and within reach of the charge-port positions of the cars that will use the bay, since ports sit in different places on different cars. The second is time. A DC session is short, so the driver typically stays with or near the car; the layout needs a waiting position that sits out of the vehicle route, not just a parking rectangle. A general site selection guide covers choosing the location; this article covers the bay once the location is chosen.
The Layout Decisions
| Decision | What to work through | Who confirms it |
|---|---|---|
| Station position | Side of the bay relative to the driver’s transfer space and the charge ports of the cars expected; floor-standing means the choice is fixed once installed | Site designer |
| Approach route | A clear, level route from the parked car to the station face, kept free of kerbs and stored items, that stays clear while a session runs | Designer, against local requirements |
| Reach to connector and LCD | The connector and the stated LCD usable by a driver who stays seated — test with a real user rather than assuming | Designer and adviser |
| Cable handling | The cable is lifted out and put back within a short session; the listing states no cable length or connector weight, so confirm both in writing and handle a sample before the layout relies on them | Supplier, in writing |
| Surface and drainage | Firm ground at the station that does not pond water where a driver stands or wheels | Site contractor |
| Marking and turnover | Marking and signs that read as a charging bay, so a short-session bay is not taken as all-day parking | Site operator |
Questions to Settle Before Installation
- Which local requirements apply to this bay, and who has confirmed them in writing?
- From a seated position in the bay, can the driver reach the connector and read the LCD without crossing the vehicle route?
- Is the confirmed cable length enough for the charge-port positions of the cars that will use this bay?
- Does the approach stay clear and level in rain, and is the bay lit well enough at night?
- Whose job is it to keep the bay clear for charging — the operator’s policy, set before opening day?
The Charger in This Layout
The EV-RHDC30K-L is a floor-standing, single-connector DC charger rated 22 kW on its product page, with an LCD, OCPP 1.6J networking and an IP54 enclosure. The floor-standing form makes placement a one-time decision, and IP54 covers the enclosure outdoors — placement, not the rating, decides whether drivers can reach and use the bay. EVDANCE’s commercial charging solutions cover the wider site picture.
Frequently Asked Questions
Are there standard dimensions for an accessible DC charging bay?
None are stated here, because requirements are set locally and vary between places and programmes. Ask the local authority or an accessibility adviser which rules apply to your site, get the answer in writing, and design to that.
Does the IP54 rating make the bay accessible?
No. IP54 describes dust and water protection for the enclosure. Whether a driver can approach, reach the connector and read the screen is decided by placement, not by the rating.
Can the same connector also serve the next bay as overflow?
One connector charges one car at a time, and the listing states no cable length. Treat any second-bay use as a layout question for the designer, settled against the confirmed cable length and the local requirements — never assumed from the drawing.
