Remote diagnostics means the operator sees the fault before a driver reports it — and some faults end at the screen. On a networked charger paired with a management platform, status, fault codes and session logs reach the operator’s desk, and configuration faults, stuck sessions and units needing a restart can be cleared without travel. What remote work cannot do is touch hardware: a damaged cable or a failed power component still needs a visit. No sourced percentage of faults is fixed remotely; your network’s figure comes from its own fault log.
Key Takeaways
- Remote diagnostics settles information faults — configuration, sessions, access — and only reports the physical ones.
- Cable damage and electrical faults always end in a visit; the remote win is dispatching it with the evidence attached.
- The capability is a pairing: a stated protocol on the charger plus a platform that surfaces codes and logs.
- Your network’s remote-fix rate comes from your own fault log — no published figure substitutes.
Fault Classes: What the Screen Can and Cannot Settle
| Fault class | Visible remotely? | Remote action | When a visit is unavoidable |
|---|---|---|---|
| Connectivity loss | Yes — as silence: the unit stops reporting | Work the platform and the site’s network path from the desk | The site’s network hardware has failed, or the unit’s communications hardware has |
| Configuration and session faults | Yes — fault codes and session logs show the state | Restart the unit, clear a stuck session, correct settings through the platform, where both support it | Rarely — this is the class remote work exists for |
| Access and payment complaints | Partly — session records show whether a charge started and what was billed | Fix the account, authorisation or platform setting | The access reader or payment hardware itself has failed |
| Connector and cable damage | Sometimes flagged as a fault — never diagnosable in detail from a code | None. A photograph from site can confirm the damage; it cannot repair it | Always: damaged hardware is replaced by a person, unit made safe first |
| Power and electrical faults | Yes — the code surfaces, with the unit in its safe state | Limited to keeping the unit safely out of service until attended | The repair itself: electrical work belongs to a licensed electrician, on site |
Read the table as a triage rule. The first three classes are information problems — everything needed is at the desk. The last two are physical: the code tells you a visit is needed, and the fastest remote action is dispatching it well, evidence attached, so the technician arrives with the right part.
What Makes Remote Diagnosis Possible
- A networked charger, paired. The charger must state a protocol a platform speaks, and actually be connected to one — the pairing our OCPP explainer sets out.
- A platform that surfaces the evidence. Status, codes and logs are platform functions. What yours shows, and which remote actions it offers, is read in its own terms.
- Stated facts per model. The EV-AC03201T dual-connector AC station and the EV-RHDC30K-L state OCPP 1.6J — a named, implemented version. The EV-ACS3210E states app control with energy monitoring and is described as OCPP-ready — a phrase to close in writing, not a pairing. The EV-ACT3204E states RFID and app access: local facts. EVDANCE offers no platform of its own.
The Records Discipline Behind Remote Fixes
Log every remote fix against the unit’s serial number: the fault, the action, the outcome, and whether a visit still had to be raised. Repeat faults then become patterns — a unit faulting every week is a replacement conversation, and the log is its evidence. Warranty claims get the same evidence, in the shape the spare parts and RMA process runs on. And your network’s actual remote-fix rate — remote closures divided by all faults, per period — is computed from the log, the only source entitled to quote it. Operators specifying remotely managed hardware can start via our commercial EV charging team or contact us.
Frequently Asked Questions
What percentage of charger faults can be fixed remotely?
No sourced figure exists, and none is quoted here. The share depends on the fault mix: an estate dominated by configuration and session faults closes most at the desk; one exposed to impact and cable damage closes few. Measure yours from the fault log: remote closures ÷ all faults, per period.
Can remote diagnostics replace scheduled site visits?
No. Condition work is physical — cables, connectors, enclosures, signage — and monitoring sees faults, not wear. Remote diagnosis covers the interval between rounds; the scheduled rounds continue.
Does every charger support remote diagnostics?
Only a networked unit paired with a platform. A model whose listing states no protocol has no remote story on paper, and a “ready” phrase is a written confirmation to close with the supplier, not a capability to plan around. Check the exact model’s stated protocol before purchase.
