EV charger installer software is field service management software built for contractors who install and maintain electric vehicle supply equipment (EVSE): Level 2 chargers for homes, workplaces and multi-unit dwellings, and DC fast chargers for fleets, retail sites and highway corridors. It manages the install as a project with external gates such as permits, utility make-ready and inspection, then tracks each charger by serial number, firmware and connector type through years of uptime-SLA repair and preventive maintenance. FSM Flow does both from one customer and site record, so the technician who answers a down-port ticket sees the commissioning photos from the day the unit went live.

Reliability is the industry’s problem to solve. ChargerHelp’s 2025 EV Charging Reliability Report, covering more than 100,000 sessions, found that nearly one in three public charge attempts fails and that charge success falls from 85% at new stations to below 70% by year three. Federally funded fast chargers under the NEVI program must average at least 97% annual uptime per port, and many state regulators and site hosts now write the same number into contracts. J.D. Power reports 14% of EV owners still left a public station without charging in 2025. Every one of those failures is a ticket, a clock and a truck roll.

FSM Flow turns that into a managed service line. Alerts from your network platform can open prioritised work orders through the workflow builder’s webhook trigger, AI matching sends the nearest technician with the right connector spares, the mobile app logs the fix and the new firmware version against the exact port, and the reporting module produces the uptime and repair-time figures your funders and site hosts ask for.

Where time gets lost

The problems that show up on every dispatcher’s screen and in every quarterly uptime report, and what FSM Flow does about each one.

  • A port goes down and the SLA clock starts before anyone knows.

    The workflow builder’s webhook trigger lets your network platform or monitoring tool open a work order the moment it raises an alert, with the site, the port and an emergency priority already set. The ticket sits at the top of the unassigned pool until a dispatcher drags it onto a tech.
    See how it works

  • Every charger looks the same in a spreadsheet.

    Each EVSE unit is an equipment record under its site with serial, kW rating, connector type, firmware version, OCPP ID and install date. Service history accumulates on the unit, so the 3.5% of stations that cause most of the downtime become visible by name.
    See how it works

  • Installs stall waiting on permits, make-ready and inspections.

    Each phase of a DCFC or MDU project is a work order with a status and an on-hold reason such as awaiting utility make-ready or inspection scheduled. The dashboard shows how long each project has waited at each gate.
    See how it works

  • Sites are 200 miles apart and techs drive past each other.

    AI technician matching weighs skill, EVITP certification and proximity for every ticket, and the week view shows the whole territory so PM rounds are grouped with nearby repairs. Route optimisation is coming soon.
    See how it works

  • Uptime reporting for funders and site hosts is assembled by hand.

    Ticket open and restore timestamps per port feed the custom report builder, so uptime percentage, mean time to repair and first-time fix are produced per site, per customer and per programme without a spreadsheet.
    See how it works

  • EVITP and licence requirements vary by project and state.

    Certifications sit on technician profiles with expiry dates. Job types can require EVITP for state-funded work, and the scheduler only suggests technicians who hold it, so the crew that arrives matches the contract.

A day with FSM Flow

How a 25-technician installer and O&M provider covering three states handles a DCFC build, a Level 2 bank and the day’s down-port tickets.

  1. 6:00 am

    Overnight alerts are already tickets

    Two network alerts arrived overnight through the webhook trigger and created emergency work orders with site, port and connector type filled in. They sit at the top of the unassigned pool.

  2. 7:15 am

    Dispatch assigns the SLA tickets

    AI matching suggests the technician 40 minutes from the first site who carries the right CCS cable assembly. One drag and the restore clock has an owner.

  3. 8:30 am

    DCFC crew on the transformer pad

    The civil crew opens the site-work phase on the mobile app, logs the trench and conduit run with photos and marks the phase ready for the electrical crew.

  4. 10:45 am

    Workplace Level 2 bank commissioned

    Twelve ports are scanned to the site record with serial, firmware and OCPP ID. The commissioning checklist closes the install phase and a workflow emails the customer the hand-over pack.

  5. 1:30 pm

    Down port restored, cause recorded

    The tech replaces a failed cellular modem, updates firmware, runs a test session and closes the ticket. The part is linked to the job and deducted from van stock.

  6. 3:00 pm

    Permit hold cleared on the MDU project

    The permit approval is attached to the on-hold work order and its status moves to scheduled; the dispatcher books the panel-upgrade crew for Thursday.

  7. 5:00 pm

    Uptime report for the site host

    The office runs the monthly report per site: uptime by port, mean time to repair and tickets by cause, and the AI assistant lists sites nearing their SLA threshold.

Compliance & records

FSM Flow stores the evidence against the project, the charger and the technician, so inspections, programme audits and warranty claims are a report away.

NEC Article 625 & permits

Load calculations, permit numbers, inspection outcomes and energy-management settings attached to each install, with checklists updated for the 2026 NEC.

EVITP certification

Certificates and expiry dates on technician profiles; California PUC §740.20 requires at least one EVITP-certified electrician per crew on most state-funded chargers, and 25% of crew electricians on projects of 25 kW or more.

NEVI uptime & reporting (23 CFR 680)

Ticket open and restore timestamps per port support the 97% average annual uptime calculation and the outage reporting that funded sites must submit.

Equipment listings & accessibility

UL 2202 and UL 2594 listing documents, ADA accessibility checks and payment-terminal tests recorded on the commissioning checklist.

Electrical safety

NFPA 70E live-work procedures and lockout checklists completed on the mobile app before work on energised switchgear, with the sign-off in the audit trail.

Utility make-ready & interconnection

Make-ready applications, utility correspondence and energisation approvals attached to the project, with on-hold reasons showing where the utility is the gate.

Numbers worth watching

Every one of these is a dashboard widget in FSM Flow, or a question you can ask the AI assistant.

  • Uptime % per port

    Calculated from ticket open and restore timestamps against each port record; reportable per site, customer and funding programme.

    NEVI minimum: 97% average annual uptime

  • Mean time to repair (MTTR)

    Hours from ticket creation to restore, split by cause code so connectivity, payment and power faults can be managed differently.

  • First-time fix rate

    Driven by van stock and unit history; return visits are a separate job type linked to the original ticket so the number is honest.

  • Truck rolls per ticket

    Visits logged per work order; repeat rolls to the same port surface the stations that need a different fix.

  • Days from contract to energisation

    Quote acceptance to commissioning phase closed, per project and per utility, showing where make-ready and permits hold the pipeline.

  • Installs per crew-week

    Completed install work orders against crew time logged, visible per crew and per charger class.

FAQ

What is EV charger installer software?
EV charger installer software is field service management software configured for contractors who install and maintain electric vehicle supply equipment. It manages Level 2 and DC fast charger installs as projects with permits, utility make-ready and inspections, records each charger by serial, firmware and connector type, and dispatches uptime-SLA repairs and preventive maintenance on the same records. FSM Flow adds AI scheduling, an AI assistant and a workflow builder on top of those core tools.
How do EV charger installers track uptime SLAs in FSM Flow?
Each service contract defines the response and restore targets for a site. Down-port tickets carry an emergency priority and the timestamps for creation, arrival and restore are recorded on the work order against the specific port. The report builder turns those timestamps into uptime percentage and mean time to repair per site, which is the figure NEVI-funded and site-host contracts ask for.
Can FSM Flow track charger serial numbers and firmware?
Yes. Every EVSE unit is an equipment record under its site with serial number, kW rating, connector type, firmware version, OCPP ID and install date. Technicians update the firmware version and parts fitted on each visit from the mobile app, so the unit’s full history is available on the next ticket.
How do I schedule preventive maintenance for networked chargers?
A service contract sets the PM interval per site, typically quarterly or semi-annual, and the checklist of filters, torque checks, thermal inspection and payment-terminal tests. FSM Flow generates the visits automatically, the dispatcher groups them with nearby repairs on the week view, and completed rounds become invoices in bulk.
Can it manage installation projects with permits, make-ready and subcontractors?
Yes. Load calculation, permit, make-ready, civil works, electrical, commissioning and network onboarding are linked work orders on one project, each with a status, an on-hold reason and its documents. Subcontractor crews get a role that shows only their assigned phases, and their photos and completion times land on the same project record.
Does FSM Flow connect to my charging network or read OCPP data?
FSM Flow does not read OCPP telemetry directly. The workflow builder has a webhook trigger, so your network management platform or monitoring tool can open a prioritised work order in FSM Flow when it raises an alert, and technicians record the OCPP ID, firmware and test result on the ticket. Uptime figures are calculated from the ticket timestamps.
How much does FSM Flow cost for an EV charging contractor?
The Professional plan is $29 per user per month with a minimum of five users, and includes scheduling, work orders, invoicing, inventory, customer and equipment management, reporting and the mobile app. Enterprise pricing is custom. Every account starts with a 14-day free trial of Professional, no credit card required, and teams of up to 3 users can stay on the Free plan at no cost.
