For a small business choosing one unit, ask how many cars plug in at once, and how long each one stays. The EV-AC03201T charges two cars at once on AC — up to 43 kW shared, 22 kW per connector — which suits cars that park for hours. The EV-RHDC30K-L charges one car at a time on 22 kW DC, which suits cars that stop for under an hour. Neither is “the faster charger” in the abstract; they answer different patterns.
Key Takeaways
- Decide on simultaneous use: two cars at once points to the dual-connector AC station; one short stop at a time, to the DC unit.
- AC speed is capped by the car’s onboard charger; DC bypasses it, set by the car’s acceptance and taper.
- Both units speak OCPP 1.6J — the platform is a tie.
- Confirm the DC unit’s connector variant in writing; the load calculation rules on the supply.
Count Cars at the Same Time, Not Cars per Day
A small site rarely runs a queue; it runs a handful of cars whose stays overlap. Test both units against yours:
| Your pattern | On the AC station (2 connectors, 43 kW shared) | On the DC unit (1 connector, 22 kW DC) |
|---|---|---|
| Two staff cars, parked all day | Both charge at once, each up to 22 kW as its onboard charger accepts | One charges; the second waits for the connector |
| A van that must turn around over lunch | It shares the 43 kW with whatever else is plugged in, at AC rates | The van has the session to itself — labelled arithmetic: about 10 kWh stored in a 30-minute stop at a sustained 22 kW, before losses and taper |
| Customers staying 30–60 minutes | Each takes what its onboard charger allows in the hour — often 11 kW-class | Each takes a DC top-up sized to the stop, set by its own DC acceptance |
Why the Same 22 kW Feels Different
AC charging is capped by the car’s onboard charger: a car that accepts 11 kW of AC takes 11 kW of the 22 kW per connector on offer. DC charging bypasses the onboard charger — the station converts the power, and the car takes DC up to its own acceptance, slowing as the battery fills. So on AC the car’s hardware sets the pace, and on DC its curve does. For a car parked eight hours, neither cap matters; for a car parked forty minutes, the DC bypass is the whole difference. Our explainer on whether EV chargers are AC or DC covers the mechanism.
What Is the Same — and What to Confirm
Both units are listed with OCPP 1.6J, so the platform does not separate them. Access differs on paper — the AC station lists RFID; the DC unit’s listing states an LCD and does not state RFID or payment hardware. The supply ask also differs: at full output the AC station asks the site for 43 kW combined, the DC unit for its 22 kW class — the installer’s load calculation, not the catalogue, decides what your supply can host.
One item needs confirming in writing before the DC unit is ordered: its connector variant — the listing names no connector standard, and the cars you serve decide what you need. The mixed answer is a legitimate end point: many small sites start with the AC station (more plugs per unit, matched to cars that stay) and add the DC unit later, when short-stay demand is proven by observation rather than assumed.
The Two Units, on Stated Facts
The EV-AC03201T is a floor-standing dual-connector AC station: two Type 2 connectors, up to 43 kW shared (22 kW per connector) with dynamic power allocation, OCPP 1.6J, RFID, a 7-inch touchscreen and an IP54 enclosure. The EV-RHDC30K-L is a single-connector DC charger: 22 kW as its product page states it, an LCD, OCPP 1.6J and IP54. Both sit in EVDANCE’s wider commercial charging range; EVDANCE is a Shenzhen manufacturer founded in 2011, and both units carry its 3-year standard warranty.
Frequently Asked Questions
Can the AC station give one car the full 43 kW?
No — 22 kW per connector is the stated ceiling, and 43 kW is the total the two connectors share. One car alone still charges at up to 22 kW, as its onboard charger accepts.
Is the DC unit faster for every car?
No. The car’s DC acceptance and its taper set the session; a car that accepts little DC gains little, and for cars parked all day, the AC station’s second connector is worth more.
Which unit asks more of my electricity supply?
At full output, the AC station: 43 kW combined against the DC unit’s 22 kW class. What your supply can host is the installer’s load calculation — that document decides.
