What EV Charger Maintenance Involves
EV charger maintenance at a commercial site covers the hardware drivers touch, the electrical supply behind it, and the software that authorizes sessions and reports status. The U.S. Department of Energy’s Alternative Fuels Data Center (AFDC) notes that routine maintenance can be minimal, but repairs can be costly once a charger is out of warranty.
- Hardware. Inspecting cables, connectors, holsters, cable management arms, screens, card readers and pedestals for cuts, cracks, bent pins and impact damage, and cleaning housings and connectors.
- Electrical. Checking the supply circuit, breakers and terminations as the manufacturer’s checklist directs. Under OSHA 29 CFR 1910.333, live parts must be deenergized and locked out or tagged before work, and only qualified persons may work on energized parts.
- Software and network. Confirming the charger reports to its network, authorizes payment, runs current firmware and delivers its rated power.
- The space. Signage, striping, wheel stops, bollards, lighting and the accessible route.
Codes, Standards and Requirements
Requirements depend on how a charger was funded, who can use it and where it is. The authority having jurisdiction applies the locally adopted electrical code to any electrical repair or replacement.
- Federally funded public chargers. Chargers funded under the National Electric Vehicle Infrastructure (NEVI) Formula Program or other Title 23 funds fall under 23 CFR Part 680. Each port must average greater than 97% annual uptime, calculated monthly over the previous 12 months (680.116(b)). A port is “up” when its hardware and software are online and available, or in use, and it delivers the required minimum power. Outages from utility interruptions, the vehicle, scheduled maintenance, vandalism or natural disasters can be excluded only where the operator can show the port would otherwise have worked. Chargers must be maintained in compliance for at least 5 years from the initial date of operation (680.106(i)), and customers must have a way to report outages (680.106(k)).
- Qualified workforce. 23 CFR 680.106(j) requires appropriately licensed, certified and trained workers for installing, maintaining and operating covered chargers. Electricians must hold Electric Vehicle Infrastructure Training Program (EVITP) certification or a certificate from a registered electrical apprenticeship program that includes charger-specific training. On projects that need more than one electrician, at least one must also be enrolled in a registered electrical apprenticeship program.
- Equipment performance. Under 680.106(d)(2), each AC Level 2 port on a covered charger must have a continuous power delivery rating of at least 6 kW, so a repair that leaves a port unable to deliver that level is not finished.
- Accessibility. U.S. Access Board guidance states that cable management systems must be kept in good condition and that cables cannot block accessible routes. It also recommends that bollards and cable slack not obstruct access aisles, and that plowed snow not obstruct access to the charger.
For privately funded chargers, contracts carry most obligations. The AFDC advises establishing whether the site host, network or installer pays for maintenance, and including a repair response time and uptime requirement in maintenance contracts.
Preventive Maintenance Schedule for EV Charging Stations
Planned maintenance finds worn cables, failing connectors and network faults before they become outages, extends equipment life and produces the uptime and repair records that funded programs and warranty claims depend on.
| Task | Recommended frequency | Basis |
|---|---|---|
| Check each port is online, authorizing sessions and reporting to the network | Dailythrough network monitoring | Facility First default |
| Review error codes for failed sessions and log outage minutes with cause | Weekly | 23 CFR 680.112 data fields (funded chargers). Frequency: Facility First default |
| Inspect cables, connectors, holsters and pedestals; confirm cables are stored securely | Monthly | U.S. DOE AFDC (check parts periodically, store cables securely). Frequency: Facility First default |
| Clean housings, screens and connectors | Monthly | U.S. DOE AFDC (keep equipment clean). Frequency: Facility First default |
| Check access aisles, accessible routes and cable management for obstructions | Monthlyand after each snow event | U.S. Access Board. Frequency: Facility First default |
| Apply firmware and network software updates | As released | Manufacturer instructions |
| Full preventive maintenance visit by a qualified electrician following the manufacturer’s checklist | Annuallyor at the manufacturer’s interval where shorter | Manufacturer instructionsInterval: Facility First default |
| Calculate uptime for each port over the previous 12 months | Monthly; must average greater than 97% (funded public chargers) | 23 CFR 680.116(b) |
| Submit session, uptime and outage data (funded chargers) | Quarterly | 23 CFR 680.112(a) |
| Report maintenance and repair cost per charging station for the previous year (funded chargers) | Annuallyon or before March 1 | 23 CFR 680.112(b) |
Facility First default is the starting interval in each program, adjusted for each site.
The authority having jurisdiction, the manufacturer, the charging network and the property’s insurer can require more frequent service, and each location’s schedule is set in its program and recorded on every visit.
Signs a Charger Needs Service
- The port shows offline or faulted in the network portal
- Repeated failed sessions or error codes, or power well below rating
- Payment or card reader failures
- Cut cable jackets, cracked connectors, bent pins or a damaged holster
- Cables left on the ground or across the accessible route
- A tripping breaker, dark screen or leaning pedestal
Records to Keep
- Session logs and error codes for failed sessions
- Outage duration and cause for each port, with evidence for any excluded outage
- Monthly uptime calculations for each port
- Inspection checklists with dated photos, and firmware update dates
- Warranty and network plan terms, and who is responsible for repairs
- Annual maintenance and repair cost per station
- Technician licenses and EVITP or apprenticeship credentials
How Facility First Runs EV Charger Maintenance Across a Portfolio
- Request. Faults arrive from network alerts, store staff or scheduled visits.
- Triage. Facility First checks warranty and network plan coverage first, so the manufacturer or network handles what it is already paid to fix.
- Dispatch. A vetted local provider with the required licenses, and EVITP or apprenticeship credentials for funded chargers, receives the work order.
- Completion. The technician documents the work with photos and confirms a successful charging session before closing out.
- Verification and invoice. Facility First checks the close-out, updates the location’s outage and cost record and invoices in one format.
Approval limits set by the client decide what proceeds automatically and what is quoted first. New chargers and replacements are handled through commercial EV charger installation. Where a damaged pedestal or exposed wiring leaves a lot unsafe or unsecured, McCray can post an officer until the work is complete (Security by McCray).
What Affects the Cost of EV Charger Maintenance
- Level 2 or DC fast charging, and the number of ports
- Networked or not, and the network plan in place
- Warranty status; the AFDC notes owners pay for repairs once a fixed warranty ends
- Parts availability, especially cables and power modules
- Funded program obligations such as credentialed technicians and reporting
- After-hours work and traffic control in the lot
EV Charger Maintenance for Retail Stores, Restaurants and Offices
Retail and shopping centers. Chargers in customer parking face vehicle strikes and cable abuse. Inspections are scheduled before opening.
Restaurants and convenience. Visits are planned around meal peaks, when chargers see the most use.
Offices and fleet sites. Staff and vehicles charge during the working day, so maintenance is set for evenings, weekends or shift changes and announced in advance.
Frequently Asked Questions
How Often Should EV Charger Maintenance Be Done at a Commercial Site?
The Facility First program default pairs daily remote monitoring with a monthly inspection and cleaning and an annual preventive maintenance visit, or the manufacturer’s interval where shorter. Funded public chargers must also average greater than 97% uptime per port, calculated monthly.
Who Can Maintain a NEVI-Funded Charger?
23 CFR 680.106(j) requires appropriately licensed, certified and trained workers. Electricians must hold EVITP certification or a certificate from a registered electrical apprenticeship program with charger-specific training, and on projects that need more than one electrician, at least one must also be enrolled in a registered electrical apprenticeship program.
Does Scheduled Maintenance Count Against Uptime?
Under 23 CFR 680.116, outages for scheduled maintenance can be excluded from the uptime calculation where the operator can show the port would otherwise have been operational.
Is Maintenance Covered by the Charger Warranty?
Sometimes. The AFDC notes warranties can be fixed-term, renewable or included with the equipment, and that most networks offer a maintenance plan for an annual fee. Coverage is checked before any repair is dispatched.
