A compact DC charger in a fleet workshop lets vehicles leave service with a useful charge, without tying up a bay for hours on AC. The EV-RHDC30K-L delivers up to 22 kW DC through a tethered CCS1 connector, bypassing the vehicle’s onboard AC charger, so even vehicles with small onboard chargers recharge at a steady rate. It needs a three-phase supply and should sit where it can reach vehicles without blocking work areas.
Key Takeaways
- A 22 kW DC unit can beat many vehicles’ AC onboard limits.
- Plan workflows so charging fits around service tasks.
- Follow manufacturer procedures for high-voltage work.
- Position the 5 m tethered cable to reach both sides of vehicles.
Why DC Helps in a Workshop
Many vans and light commercial vehicles have AC onboard chargers of 7 to 11 kW. On a DC charger, the charging power is set by the charger and the battery’s acceptance, not the onboard AC charger. A 22 kW DC unit therefore charges some fleet vehicles two to three times faster than their AC limit allows. During a two-hour service, that can add around 40 kWh, depending on the vehicle and its state of charge. U.S. DOT guidance describes DC fast charging as 50 to 350 kW; a 22 kW DC unit sits below that range but above most AC onboard limits.
Workflow Options
| Workflow | How it works | Benefit |
|---|---|---|
| Charge on arrival | Plug in at a staging bay before service starts | Vehicle charges while waiting for a technician |
| Charge during service | DC unit beside a service bay | No extra moves; requires cable reach and safe routing |
| Charge before release | Dedicated release bay with DC | Vehicles leave with a known charge level |
| Overnight top-up | Workshop vehicles charge after hours | Uses the unit when the workshop is closed |
Always follow the vehicle manufacturer’s service procedures, which may require charging to be stopped or the high-voltage system isolated for certain work.
Power and Installation
The unit takes a 380 to 415 V three-phase input. An electrician should confirm workshop capacity alongside compressors, lifts and welders, and decide whether charging should be limited when other heavy loads run. The tethered cable is 5 m, so position the pedestal where it reaches charge ports on both sides of typical vehicles. Read how DC chargers work and depot charging for vans.
Safety in a Working Environment
- Keep the pedestal clear of lift arms, vehicle swing paths and forklift routes.
- Protect it with bollards.
- Route the cable so technicians do not trip over it.
- Use RFID or app authorization so only trained staff start sessions.
- Include the charger in workshop inspection routines.
Connectivity and Records
OCPP 1.6J lets the fleet manager see energy delivered per vehicle, which is useful for cost allocation. The unit also supports RFID and app authorization and has an LCD status display.
The EV-RHDC30K-L is a floor-standing DC charger rated at 22 kW continuous with a single tethered CCS1 connector, IP54 enclosure, OCPP 1.6J and a 3-year warranty. Vehicles with a different DC inlet need equipment approved for them.
Frequently Asked Questions
Why use DC instead of AC in a workshop?
DC bypasses the vehicle’s onboard AC charger, so vehicles with 7 to 11 kW onboard chargers can recharge faster at 22 kW DC.
Can vehicles charge while being serviced?
Sometimes, but follow the manufacturer’s procedures. Some work requires the high-voltage system to be isolated.
What supply does the EV-RHDC30K-L need?
A three-phase 380 to 415 V supply, sized by an electrician for the site’s other loads.
