A maintenance plan for a public charging site is a short written document, not a longer checklist. It ties the station manual’s service intervals to the operator’s routine rounds, keeps a fault log through the charging platform, and names who gets called when a check finds a problem. The generic tasks are covered by the site’s commercial EV charger maintenance checklist; the plan turns that list into a schedule with owners and records.
Key Takeaways
- A maintenance plan schedules owners, intervals, and records; the task checklist is a separate document.
- Service intervals come from the manual and installer — never invent them.
- The platform fault log and a named escalation path shorten downtime on a public site.
- Uptime targets are the operator’s goals; the NEVI 97% figure is a funding-programme rule, not a product promise.
A Plan Is a Schedule, Not a Task List
The two documents answer different questions. A checklist says what to look at: cables, connectors, enclosure, screen. A plan says when each item is looked at, who does it, what gets written down, and what happens next. For a public site running a dual-connector station such as the EV-AC03201T, one fault can take two bays out at once, so the plan is what a site manager is judged on.
One rule governs the document: service intervals come from the station’s manual and the installer’s handover notes. This article sets none of its own, because an invented interval is not a maintenance requirement. The plan schedules the operator’s rounds around the manual’s intervals; it never replaces them.
The Plan on One Page
Most public sites can hold the plan to a single page per station. These elements have to be decided and written down; the rhythm for each comes from the manual and the operator’s judgement.
| Plan element | What it records | Where the requirement comes from |
|---|---|---|
| Routine visual round | Date, station, connector checked, anything seen — cable wear, connector damage, screen state | Operator’s own schedule |
| Manual service items | Each task the manual lists, marked done with date and name | The manual and installer’s handover — never this article |
| Fault log review | Faults the platform reports, how long each lasted, what closed it | Platform records (station connects via OCPP 1.6J) |
| Escalation path | Named installer and manufacturer contacts, warranty reference | Purchase documents and the 3-year standard warranty |
Faults, Records and the Escalation Path
A public station earns its keep only while both connectors work, so the plan treats records as a working tool, not paperwork. Because the EV-AC03201T reports to a platform over OCPP 1.6J, faults surface there first; the plan says who reviews it, how often, and which faults trigger a site visit rather than a remote check.
Each entry needs the same fields: date, station, which connector, what was observed, and what closed the fault. Operator checks stop at what can be seen and reported — anything inside the enclosure belongs to the installer or manufacturer, and a clean log shows when a fault began and whether it repeats. How commercial charging stations work explains that platform connection.
Damage, Downtime and Uptime Targets
Public sites also plan for damage no service interval prevents. Graffiti, a cracked screen, or a car rolling into the pedestal are handled by the operator’s own arrangements: make the station safe, photograph the damage, log it, escalate. The plan should not promise the hardware resists any of this — the listing’s IP54 rating covers dust and water, not impact.
Uptime targets are likewise goals the operator sets, not figures the product guarantees. One exception: where a site is funded under the US NEVI programme, 23 CFR Part 680 requires average annual uptime above 97% — a funding-programme requirement, not a performance promise for this station.
The Station This Plan Was Written Around
The EV-AC03201T is a floor-standing AC station with two Type 2 connectors sharing up to 43 kW (22 kW per connector, dynamically distributed), a 7-inch touchscreen, RFID access, OCPP 1.6J platform connection, and an IP54 enclosure — two connectors to check and a platform to review.

Frequently Asked Questions
Who writes the maintenance plan for a public charging site?
The operator does, using the station manual and the installer’s handover notes as inputs. Suppliers provide intervals and escalation contacts; the operator turns them into a schedule with named owners.
How often should a public EV charger be serviced?
At the intervals its manual and installer specify — there is no universal figure this article can honestly give you. Between services, the operator’s rounds run on a rhythm the operator sets.
Does a maintenance plan cover repairs?
No. The plan covers checks, records, and escalation. Repairs inside the enclosure are for the installer or the manufacturer, and EVDANCE hardware carries a 3-year standard warranty. A complete fault log makes escalation faster.
