A municipal fleet is not one fleet: police cars, council vans and utility trucks share a depot but not a duty pattern. Most of their charging is overnight AC. The gap a compact DC unit fills is the vehicle that comes back mid-shift and has to go out again — on the EV-RHDC30K-L, an hour at up to 22 kW DC stores roughly 20 kWh before taper, enough to return a vehicle to duty the same day.
Key Takeaways
- Draw the fleet’s own duty picture first; the charging plan follows it, not the other way round.
- Overnight AC does the bulk; one 22 kW DC connector covers the returns that cannot wait.
- Readiness targets belong to the service; the lane serves them and guarantees nothing by itself.
- Sessions land in the fleet’s platform records over OCPP 1.6J; accounts and cost splits are the fleet’s arrangements.
One Depot, Several Duty Patterns
Start from the fleet’s own picture of its vehicles — which ones leave and return like clockwork, and which ones answer calls. A planning shape most mixed fleets recognise:
| Vehicle group | Its pattern | Its charging answer |
|---|---|---|
| Pool cars and inspectors’ cars | Out all day, back by evening | The overnight AC row |
| Council vans and works trucks | Set rounds, back mid-afternoon | Overnight AC; the DC lane when a second run appears |
| Response and utility vehicles | Unpredictable call-outs, short depot stops | The DC lane first; AC whenever parked |
The groups are illustrations. Your fleet’s real groups, and which of them ever truly cannot wait, come from your own logs — that picture, not this table, sizes the installation. Sizing the AC side is covered in our guide to fleet depot charging for vans and light commercial vehicles.
The DC Lane Is for Exceptions
One connector serves one vehicle at a time, so the lane works on a rota — the fleet manager’s document, not the charger’s. The arithmetic is labelled ceiling maths: a 30-minute stop stores roughly 10 kWh before taper, an hour roughly 20 kWh, allowing for losses. Plan the stop to a working level — enough for the next call or the rest of the shift — rather than to a full battery, and the lane keeps moving. The honest sizing method is to log a month of returns that could not wait for the overnight row, then decide whether one lane covers them.
Readiness Is the Fleet’s Own Target
How ready a response vehicle must be, and how fast it must turn around, are decisions each service makes for itself; no charger specification sets them, and this article states none. The charging plan serves the target the fleet has set — it does not create one. Keep the limits in the plan too: one connector queues, a vehicle’s own DC acceptance caps its rate, and every battery tapers as it fills. A DC lane widens a fleet’s options between duties; it is not, on its own, an availability guarantee.
Records, Access and Cost Centres
The unit speaks OCPP 1.6J, so its sessions land in the same platform records as the rest of the fleet’s charging — the mechanism behind how commercial charging stations work. Which crews and departments charge under which cards or accounts is the fleet’s own arrangement, managed the way RFID and user management for shared chargers describes. Splitting the energy cost between services afterwards is the council’s own accounting choice, worked from those records — a back-office task, not a charger feature.
The EV-RHDC30K-L in a Municipal Depot
The EV-RHDC30K-L is a floor-standing DC charger rated at 22 kW on its product page, with a single connector, an LCD and an IP54 enclosure for depot yards. It carries the 3-year standard warranty. A mixed fleet makes one check decisive: vehicles differ, and the listing does not name the DC connector standard — confirm in writing, before ordering, that the fitted connector matches the vehicles that will use the lane. The wider commercial charging range covers the AC row beside it.
Frequently Asked Questions
Can one unit keep response vehicles ready around the clock?
No single connector can promise that, and readiness is a fleet plan — vehicles, rota and spares — not a charger feature. The lane improves turnaround between duties; the readiness target itself is the service’s own decision.
Does a DC lane replace the depot’s AC chargers?
No. AC owns the overnight bulk, where vehicles sit for hours and speed buys nothing. The DC lane exists for the minority of returns that cannot wait for that row.
Which vehicles can use the lane?
Any vehicle whose DC inlet matches the fitted connector and that accepts DC charging — acceptance varies by model, so check each vehicle’s handbook. Because the listing does not name the connector standard, that match is a written confirmation before ordering.
