No agency publishes a yearly count of failed public-charger inspections, so there is no honest number to quote — anyone offering one is mixing inspection regimes that count different things. The useful half can be answered: public chargers fail on a short, repeating list of faults, most checkable before the inspector arrives.
Key Takeaways
- No published yearly count of failed public-charger inspections exists; inspection regimes differ and are not added together.
- The repeating faults are drift: worn cables and connectors, price displays that disagree with billing, faded markings, blocked aisles, dead payment routes.
- Prepare against your own permit and programme text, with a full test session and a current maintenance log.
- Most findings are cheap to close before the visit and formal during it.

Why There Is No Count to Quote
“Inspection” names several different events. A new installation is signed off against its permit and the electrical code. An operating public station may be checked by a metering authority for billing accuracy, by a local authority for electrical condition, or by a funding programme’s auditors against the programme’s conditions. Each has its own pass list and failure definition, and none publish into one shared total. The regime that applies to your station is written in its permits and programme paperwork — that text, not a national statistic, is what your preparation should follow.
The Faults That Come Up Again and Again
| Category | Typical fault | The operator’s pre-check |
|---|---|---|
| Electrical condition | Damaged cable or connector, cracked enclosure, water inside, protection tripped and left | Walk every unit — cable, connector, housing, seals; an electrician for anything internal |
| Metering and price display | The price shown does not match billing, or metering and accuracy labels are missing or out of date | Run a session, then compare screen, app and receipt line by line |
| Signage and bay markings | Faded or missing bay markings, terms of use not posted, a support number that is wrong or gone | Read the bay as a new driver: markings, posted terms, support contact |
| Accessibility | Access aisle blocked, or furniture and bollards added later obstruct the approach | Check the approach and aisle are clear, as the approved layout left them |
| Payment and availability | Advertised payment route broken, or a long-dead unit still presented as available | Complete a paid session on every payment route the station offers |
Most of these faults are drift, not design: the station passed when it opened, then cables wore, markings faded and a planter crept into the aisle. They are also the faults a driver would find first. The electrical safety side sits under the National Electrical Code, and the upkeep rhythm that prevents drift is in our commercial charger maintenance checklist.
The Pre-Inspection Routine
- Read your own paperwork first. The permit conditions and programme terms name what will be checked; prepare against that list, not a generic one.
- Walk the bay as the inspector will. Markings, signage, aisle, approach, lighting — in that order, from the driver’s seat.
- Test a full session on every unit. Start, charge, pay, stop; the receipt proves metering, display and payment agree.
- Close the small faults immediately. Replacement labels, re-painted markings and a corrected support number are cheap before the visit.
- Keep the maintenance log current. A documented routine is the evidence that faults are drift you manage, not neglect.

Hardware That Holds Up Between Inspections
Equipment choice does not pass an inspection — the maintained site does — but rated hardware drifts less. The EV-AC03201T dual-connector AC station (two Type 2 connectors, up to 43 kW shared, OCPP 1.6J, RFID, IP54) produces the per-session records an operator needs to check metering against billing, and the EV-RHDC30K-L compact DC charger (22 kW DC, OCPP 1.6J, IP54) follows the same pattern outdoors. On funded corridor sites, the NEVI standards also expect average annual uptime above 97% — a standing duty, not a one-day result. See our commercial charging range for public-site hardware.
Frequently Asked Questions
Who inspects an operating public charger?
It depends on the regime: a local electrical authority, a metering or weights-and-measures authority, or a funding programme’s auditors — sometimes more than one. Your permits and programme paperwork say which apply.
What happens after a failed inspection?
The usual pattern is findings, a period to correct them, and a re-check; safety faults can take a unit out of service until fixed. The exact consequences sit in the authority’s own process.
Is the sign-off of a new installation the same inspection?
No. The installation sign-off compares the finished work with the permit and the code before the station opens. These inspections happen later, on a station in service — which is why condition, metering and signage dominate their fault lists. What an installation itself includes is set out in our guide to standard EV charger installation.
