EV charging infrastructure has moved from a tenant amenity to a core facility asset — one that generates revenue, satisfies ESG commitments, and increasingly determines whether a commercial property can attract premium tenants. But chargers that go offline, deliver inconsistent power, or lack service history create the opposite effect: complaints, liability gaps, and expensive emergency repairs that eliminate months of charging revenue in a single incident. Oxmaint's Asset Lifecycle Management platform gives facility teams structured inspection workflows, uptime dashboards, and energy analytics for every EV charger on the property — or book a free 30-minute demo to see how EV asset tracking works in practice.
Why EV Charger Maintenance Fails in Most Facilities
Most facility maintenance programs were not designed with EV charging in mind. Chargers are treated as IT infrastructure by some teams and electrical equipment by others — falling into the gap between both. Without a dedicated asset record, inspection schedule, and energy monitoring integration, charger problems go undetected until a tenant or visitor reports a failure.
01
No Asset Record
Charger model, installation date, warranty status, and service history stored in email threads — or nowhere. No record means no accountability and no data for warranty claims.
02
No Inspection Schedule
Chargers are checked only when a complaint is received. Cable wear, connector degradation, and GFCI failures accumulate undetected between reactive service calls.
03
No Energy Monitoring
Without kWh dispensing data per session and per charger, facilities cannot track utilisation, identify underperforming units, or bill accurately for energy consumed.
04
No Uptime Tracking
Charger availability is unmeasured, making it impossible to report uptime for utility incentive programs, EV-ready building certifications, or tenant SLA compliance.
The Complete EV Charger Maintenance Schedule
A structured maintenance program for commercial EV charging infrastructure covers four frequency tiers. Skipping any tier shifts maintenance cost from planned to emergency — typically at a 4 to 6 times cost premium plus the associated revenue loss during outage.

Stop Managing EV Chargers Reactively
Oxmaint schedules every inspection, routes tasks to the right team, captures findings with photos, and tracks work orders to completion — so no charger goes uninspected and no deficiency goes unresolved. See the full workflow in a 30-minute demo.
EV Charger Energy Analytics: What Facilities Should Be Tracking
Energy data from EV chargers is a strategic asset — not just an operational metric. When captured and analysed properly, it informs pricing strategy, capacity planning, demand charge management, and ESG reporting simultaneously. Oxmaint aggregates charger-level energy data into dashboards that serve all four use cases.
01
kWh Dispensed per Session
Tracks actual energy delivered per charging event, enabling accurate cost recovery billing for tenants and employees. Identifies underperforming chargers delivering below rated output.
02
Peak vs Off-Peak Utilisation
Reveals when chargers are drawing maximum power, enabling load scheduling to reduce peak demand charges — often the largest single energy cost line item in commercial facility bills.
03
Charger Uptime Rate
Measures availability by charger and by portfolio. Required for utility incentive program compliance and EV-ready building certification. Industry benchmark is 95%+ for Tier 2 chargers.
04
Carbon Offset Equivalent
Converts kWh dispensed to CO2 equivalent offset versus ICE vehicles, producing the ESG metric that feeds directly into GRESB transportation impact reporting and sustainability disclosures.

Certified Facility Manager (CFM) · EV Infrastructure Specialist, BOMA Member
"The facilities I consult with consistently underestimate what it takes to maintain EV charging infrastructure at a level that actually delivers the ROI they projected. The charger purchase and installation are visible costs. The ongoing maintenance — cable replacements, GFCI failures, firmware issues, energy reconciliation — these are invisible until they compound into a problem that takes chargers offline for days. A structured asset management approach that tracks every charger's inspection history, energy output, and service record is the difference between an EV program that generates revenue and one that generates complaints. Oxmaint is the only CMMS I have seen that handles EV assets with the same rigour it applies to HVAC or electrical systems."
Frequently Asked Questions
How does Oxmaint integrate with EV charging network management systems?
Oxmaint integrates with OCPP-compliant charging network management systems via API, pulling session data, error codes, and uptime status directly into the asset record for each charger. This eliminates manual data entry between the charging network portal and your CMMS, and ensures that fault alerts from the network are automatically converted into work orders in Oxmaint assigned to the appropriate technician.

Can Oxmaint track warranty status and service history for each individual EV charger?
Yes. Each EV charger in Oxmaint is registered as an individual asset with its own record containing make, model, serial number, installation date, warranty expiry, OEM service contract terms, and complete maintenance history. When a warranty claim needs to be filed, all relevant service records, inspection reports, and fault logs are immediately accessible and exportable — which is critical for warranty claims that depend on proving proper maintenance was performed. The system also sends proactive alerts before warranty periods expire so renewal or replacement decisions can be planned in advance.
How can EV charger maintenance scheduling reduce peak demand charges?
Oxmaint's energy analytics dashboard shows exactly when EV chargers create peak demand spikes on the facility's electrical load profile. Using this data, facility teams can configure charging schedules — restricting simultaneous high-power sessions during peak tariff windows — and schedule maintenance during low-utilisation periods that would otherwise create demand spikes. Facilities using Oxmaint for coordinated EV load management alongside HVAC scheduling report peak demand charge reductions of 12 to 18% on average.

What certifications or compliance requirements apply to commercial EV charging maintenance?
Commercial EV charging systems in the US must comply with NEC Article 625 (Electric Vehicle Charging System), UL 2202 and UL 2231 standards for equipment safety, and applicable local electrical codes. Annual electrical certification by a licensed electrician is required in most jurisdictions. EVSE installations receiving federal or state incentive funding often have additional uptime and maintenance documentation requirements that must be met for continued incentive eligibility. Oxmaint's compliance tracking module captures and stores all required documentation, creating an audit trail for both regulatory inspections and incentive programme compliance reviews.
