On a DC charger, the screen is the conversation between the driver and the station. The EV-RHDC30K-L listing states an LCD, and its job across a session is simple: confirm the session has started, show that charging is under way, and confirm the stop. The battery’s side of the story appears on the car’s own dashboard, and the session record lives with the operator’s platform — three witnesses, each showing its own part.
Key Takeaways
- The listing states an LCD: it confirms the start, shows the session live, and confirms the stop.
- The car’s dashboard tells the battery’s side; the operator’s platform holds the record. Different witnesses, different numbers.
- No field list, menu, language set or payment flow is published — the manual and a sample unit answer those.
- Confirm the fitted DC connector matches your car in writing; the listing does not name the standard.

A Session in Four Stages: What You See, and Where
The order of operations at any DC charger is covered in our guide to using a DC fast charger step by step. This guide is narrower — what tells you each stage has happened:
| Stage | What you need to know | Where you see it |
|---|---|---|
| Connect | The connector is seated and the station is ready for you | The unit’s LCD shows its ready state; the car confirms the connection in its own way |
| Authorise | The station knows who is charging | Confirmation on the LCD; how you authorise is the operator’s arrangement (their card or account) |
| Charging | Energy is flowing and the session is live | The LCD shows the session under way; the car’s dashboard shows the battery’s state and the rate the car is accepting |
| Stop | The session has ended and the record is closed | The LCD confirms the end; the platform holds the session record and any receipt |
Three Witnesses, Three Different Stories
Drivers sometimes worry when the numbers in front of them do not match. They are not supposed to:
- The LCD reports the station’s side — the session’s state, from the charger’s point of view.
- The car’s dashboard reports the battery’s side — state of charge and what the car is accepting. When a session slows as the battery fills, that is the car’s taper, explained in how DC fast chargers work.
- The operator’s platform holds the record — times and energy for the operator’s accounts, reached over the unit’s stated OCPP 1.6J link.
Energy delivered at the connector and energy stored in the battery also differ by the session’s losses. A small gap between witnesses is physics, not a fault.
What the Listing Does Not Specify
The listing states an LCD and stops there. It does not publish a field list, a menu structure, a language set, or an on-screen payment flow, and this guide does not invent them. Treat the exact interface as a document question: the manual describes it, a sample unit shows it, and a fleet order should confirm it in writing before the order is placed. The same applies to authorisation — the method belongs to the operator’s platform arrangement, not to a screen feature anyone should assume.
The EV-RHDC30K-L’s Screen in Context
The EV-RHDC30K-L is a floor-standing DC charger rated at 22 kW on its product page, with a single connector, the LCD covered here, an IP54 enclosure and OCPP 1.6J. It carries the 3-year standard warranty. One check matters before any first session: the listing does not name the DC connector standard, so confirm in writing that the fitted connector matches your car. Operators comparing hardware can start from the commercial charging range.

Frequently Asked Questions
Does the screen show what the session costs?
That depends on the operator’s tariff arrangement on their platform. The listing does not specify an on-screen price display, so ask the operator — or, before a fleet order, the manufacturer — in writing.
Can I stop the session from the screen?
Stopping is part of the session flow, but the exact controls are a manual-and-sample detail the listing does not describe. Your car also has its own way to end a session, set by the vehicle maker.
The screen and my car show different numbers. Which is right?
Both, about different things. The screen reports the station’s side of the session; the car reports its battery’s state of charge. They measure different quantities, so a small difference is expected.
