Most hotel charging is overnight, and overnight belongs to AC. A DC unit earns its place at a hotel on the short windows AC cannot serve: the late arrival who needs a ready car by morning, the mid-stay top-up before an evening out, the forgotten charge discovered at checkout. The EV-RHDC30K-L — a compact 22 kW DC charger — is the short-stay half of a hotel’s charging, beside an AC row that handles the night.
Key Takeaways
- Hotel DC is for short windows — late arrivals, mid-stay turnarounds, the forgotten charge at checkout — not for the overnight majority.
- The planning answer is a mixed layout: an AC row for the night, one DC unit near the entrance for the deadlines.
- Top-up energies are small (roughly 10–20 kWh), so compact 22 kW DC fits the job; corridor-class power would idle.
- Access, pricing and records run through the hotel’s platform over OCPP 1.6J.
Three Short-Stay Patterns
Each pattern is a labelled scenario, its energy worked as arithmetic at a sustained 22 kW, before losses and the taper that ends every DC session. They share one shape: a near deadline, and a top-up rather than a fill.
| The pattern | The window | What the guest needs |
|---|---|---|
| The late arrival | Arrives near midnight, low, with an early start | An hour on DC before bed — roughly 20 kWh class, enough for the morning’s first leg; or the AC row, if a bay is free all night |
| The mid-stay turnaround | Back from a day trip at five, out to dinner at seven | A top-up inside the turnaround — the car charges while the guest changes |
| The forgotten charge | Checkout discovers a battery too low for the drive home | Thirty to sixty minutes while bags are packed — a survivable wait; the same energy on AC would take hours |
Notice what none of these patterns needs: a corridor-class charger. The energies are top-up sized, the stays an hour or so, and one or two cars a day is the realistic load — from your own front desk’s experience, not an industry figure.
The Mixed Layout: an AC Row Plus One DC Unit
The planning conclusion for most hotels is a mixture, not a conversion. The overnight majority is served by AC bays — cars parked eight hours or more need availability, not speed, and our hotel EV charging guide plans that side. The DC unit stands apart, typically near the entrance, where a short-stay car can charge and move on without taking an overnight bay. One connector serves one car at a time, so the desk’s routine does the queueing through the evening’s short windows. That routine is the hotel’s own arrangement, not a product feature.
Running It: Access, Price and Records
The unit connects to the hotel’s charging platform over OCPP 1.6J — its stated protocol — so DC sessions sit in the same arrangement as the rest of the hotel’s charging: one set of records. The driver works at the unit’s LCD. How a guest is authorised, and what they pay, are the hotel’s choices in that arrangement: whether charging is an amenity or a paid extra is an open question in the sector, and our overview of whether hotel EV charging is free shows the range of practice. A DC top-up is a candidate for a per-session price where AC is bundled — a tariff decision for the hotel, not a property of the charger.
The EV-RHDC30K-L for Hotels
The EV-RHDC30K-L is EVDANCE’s compact DC charger: 22 kW as the product page states it, floor-standing, single connector, IP54 for the car park, an LCD for the driver and OCPP 1.6J for the platform. EVDANCE is a Shenzhen manufacturer founded in 2011, and the unit carries its 3-year standard warranty. Hotels planning the full mix can start from the commercial charging range.
Frequently Asked Questions
Should a hotel replace its AC chargers with DC?
No — dwell decides. Guests parked overnight are served better by more AC bays, because every car finishes long before checkout. DC answers a different, smaller set of moments: short windows and deadlines.
How long will a guest wait at the DC unit?
Labelled arithmetic: at a sustained 22 kW, half an hour delivers roughly 10 kWh before losses and taper; an hour, roughly 20 kWh. A top-up for the next leg — set expectations to a useful charge inside the wait, not a full battery.
What does a compact DC unit cost a hotel to install?
No figure is stated for this class; the U.S. DOE figures describe corridor-class DC fast charging, not this unit. A 22 kW-class draw is a smaller supply job than a 50 kW+ installation — your installer’s quote for your site is the only honest number.
