A DC session that will not start is usually blocked at one of three gates: authorisation, the connector handshake, or the station’s own state. On the EV-RHDC30K-L — a 22 kW floor-standing DC charger with a single connector, IP54 and OCPP 1.6J — you can separate those gates with what you can see: the car’s own display, the station’s LCD, and one simple test, a second vehicle. Work the gates in order and write down what each one showed.
Key Takeaways
- Split a no-start into three gates: authorisation, connector handshake, station state.
- The car’s own display and the station’s LCD are evidence — record both, word for word.
- A second vehicle at the same connector is the decisive isolation test.
- No error codes or reset steps are published for this model — escalate with a record under the 3-year warranty instead of guessing.

Gate One: Authorisation
A networked DC charger starts only when the session is authorised under the operator’s own arrangement — their platform account, card, or app flow. That arrangement belongs to the operator and the platform, not to this article: check first whether the driver’s authorisation was accepted at all. If the platform shows no start request, the block is before the charger. If it shows a request refused, the refusal reason lives with the platform provider. Our overview of RFID and user management covers the account-side questions operators pin down in advance.
Gate Two: Connector and Handshake
| What you observe | What it points to |
|---|---|
| Connector not fully seated, or the car reports a connection problem | The physical link — reseat once, inspect the connector face for damage or debris |
| Car’s display shows its own charging message or refusal | The vehicle side of the handshake — the car’s message is evidence; record it word for word |
| Station LCD shows the session never left the start screen | The start sequence stalled between the two — the second-vehicle test separates car from charger |
DC charging is a conversation between car and charger before any power flows. This article deliberately does not decode that conversation step by step: the listing publishes no handshake sequence and no error codes for this model, and inventing either would mislead you. What you can trust is the isolation test below.

The Second-Vehicle Test
- Try a different vehicle at the same charger, with a known-good authorisation.
- Second car starts: the charger and its authorisation path work — the first car’s side holds the answer; its display message is the lead.
- Second car also fails: the charger, its connection to the platform, or the site supply is the suspect — escalate with the record below.
- Note the time, both vehicles, and exactly what each screen showed.
This is a no-start problem — different from a session that starts and runs slowly, which has its own causes. The general driver checklist in why a charger is not working covers the basics that apply before model-specific diagnosis.
The Escalation Record
If the second vehicle fails too, send support a record, not an impression: date and time, the site and charger identity, both vehicles tried, what the car displays said, what the station LCD showed, and whether authorisation was accepted in the platform. The EV-RHDC30K-L stands behind EVDANCE’s 3-year standard warranty; route the record through EVDANCE support. Do not open the cabinet or attempt resets the manual does not describe — internal diagnosis is a qualified technician’s job.
Frequently Asked Questions
The charger shows an error code. What does it mean?
The published listing gives no error-code table for this model, so this article will not guess one. Photograph the code, include it in the escalation record, and let EVDANCE or the manual decode it.
Should I restart the charger to clear the fault?
Only if the manual for this model describes that step for this situation. A restart also erases the state support needs to see — record the screens first, then follow the manual, not habit.
Another car charged fine yesterday. Does that clear the charger?
Not completely — but it shifts the odds toward today’s vehicle or today’s authorisation. Run the second-vehicle test now rather than reasoning from yesterday.
