EV charger maintenance and installation software: from site survey to uptime report
A charger is installed once and then has to stay up for years. The installer needs a survey with the right photos before anyone prices it, a permit pack, and a commissioning record. The maintainer needs every fault ticket from the operator or helpdesk turned into a visit with an SLA, a preventive maintenance plan per unit, the right parts on the van, and evidence that counts toward uptime. This guide covers the uptime rules in the US and UK, permits, commissioning, PPM, fault tickets and the software, with a source on every rule.

A 30-minute call. We show you EV charger installation and maintenance companies workflows running in Fieldproxy, built around how you work.
Short answer
EV charger installers and maintenance teams usually run a mix: a charge point management system (CSMS) such as Driivz or Ampcontrol for monitoring and remote resets, a helpdesk such as Zendesk for operator and driver tickets, a field service or CMMS tool for the visits, and spreadsheets for surveys, permits and van stock. The parts that break are the hand-offs: a fault ticket that does not become a visit with the SLA attached, a survey missing the panel photo, a commissioning sheet nobody can find, and a planned outage nobody recorded. Fieldproxy is one option. It is set up around your own survey, commissioning and PPM checklists, with required photos, SLA clocks per contract, van stock, and subcontractor links that show the sub only their job.

How a job runs
One EV charger maintenance job, from first call to paid
The order the work really happens in, and what has to be written down at each step so nothing is argued about later.
- 1
Capture the lead with the survey photos
A homeowner, site host or fleet manager asks for a charger. Before anyone prices it, collect the minimum photos. One installer put it this way: 'We need to have at least 4 photos, which is of your main panel, the location of where you want the EV charger, what the distance is.' Add the panel label, the meter and the cable route, and make each one required so the lead cannot move to quoting without them.
- 2
Survey the site and size the load
On a remote or on-site survey, record the service size, spare capacity, the run length, the mounting surface, trenching or ducting, and whether load management avoids a service upgrade. In the US, NEC Article 625 treats EV charging as a continuous load; in the UK the IET Code of Practice and BS 7671 set the design. In the UK, check whether the distribution network operator (DNO) has to be told or asked before connection.
- 3
Quote with options
Price the charger, the circuit, the panel work and any civils as options the customer can pick from, such as a straight install, an install with load management, or an install with a panel upgrade. Attach the photos so the customer sees what the price is based on.
- 4
Build the permit pack
A typical permit application includes a site plan, a single line electrical diagram, load calculations and whether a panel upgrade is needed, and the manufacturer's installation instructions (GO-Biz guidebook). Track it as its own stage with the submission date and the authority's reference, so the install is not booked before approval.
- 5
Install and commission
The electrician installs, tests and commissions: insulation and earth fault loop or GFCI tests, RCD or protective device checks, the charger's network connection to the CSMS over OCPP, a test charge, and photos of the finished unit with its serial plate. For UK grant claims the photos have to show the model, serial number and the parking space it serves (Workplace Charging Scheme).
- 6
Hand over and register the asset
Issue the certificate and commissioning report, and register the charger as an asset on the site record: make, model, serial, firmware, power rating, connectors, install date and warranty end. Every later ticket and PPM visit attaches to this record.
- 7
Plan preventive maintenance per unit
Set PPM visits from each model's manufacturer schedule and the contract: monthly or quarterly checks of cables, connectors, screens and enclosures, and filter and fan work on DC units at the intervals the manufacturer gives. Busy or dusty sites need shorter intervals.
- 8
Turn every fault ticket into a visit with an SLA
Faults arrive from the CSMS, from the operator's helpdesk or from a driver's call to the operator. Remote resets fix many. The rest become a corrective visit with the response and restore clock from the contract, the ticket reference carried both ways, and the site access notes the engineer needs.
- 9
Fix, record and close with evidence
On site the engineer follows the fault checklist, records readings, parts used from van stock, photos before and after, and the restore time. The closing note goes back to the ticket, and the outage minutes are classed so they count correctly toward uptime.
- 10
Report uptime and invoice
Each month, report visits, restore times, repeat faults per unit and parts consumed to the operator or site host, then invoice by contract: PPM at the agreed rate, reactive work at contract rates, and parts. Warranty failures are recorded against the manufacturer.

Rules and standards
The rules that shape the work, with their sources
| Rule | What it means on the job |
|---|---|
| NEVI uptime: greater than 97% per port | Each federally funded charging port must average more than 97% uptime a year, calculated monthly over the previous 12 months. Scheduled maintenance, utility interruptions, vehicle-caused faults, vandalism and natural disasters can be excluded if the operator can show the port would otherwise have worked. Unscheduled repairs count as downtime. source: 23 CFR 680.116, Information on publicly available charging infrastructure: uptime (Cornell LII) |
| NEVI qualified technicians and 5-year maintenance | Electricians installing, operating or maintaining NEVI-funded chargers need EVITP certification or a registered apprenticeship credential with charger-specific training, and chargers must be maintained in compliance for at least 5 years from first operation. Corridor stations need at least four networked DCFC ports of at least 150 kW continuous. source: 23 CFR 680.106, Installation, operation and maintenance by qualified technicians (Cornell LII) |
| EVITP certification | The Electric Vehicle Infrastructure Training Program trains licensed electricians who install EV supply equipment; certified electricians must pass an exam. Keep the certificate and expiry on each technician's record so dispatch can check it. source: EVITP, Electric Vehicle Infrastructure Training Program (electrician certification) |
| UK Public Charge Point Regulations 2023: 99% reliability | Rapid public charge points (50 kW and above) must be available 99% of the time on average across the operator's rapid network each calendar year, measured from OCPI statuses. INOPERATIVE and OUTOFORDER count as downtime; an evidenced blockage such as planned non-fault maintenance, or exceptional events such as vandalism or grid failure, can be exempt. Reports go to OZEV and OPSS by 14 January each year. source: GOV.UK, The Public Charge Point Regulations 2023: guidance (reliability, helpline, contactless, open data) |
| UK 24/7 helpline, contactless and open data | Public operators need a free, staffed helpline 24 hours a day, 365 days a year; contactless payment on new public points of 8 kW and above and all of 50 kW and above; and open data where each status change shows within 30 seconds. source: GOV.UK, The Public Charge Point Regulations 2023: guidance (reliability, helpline, contactless, open data) |
| UK grant installs: photos, standards, warranty | Workplace Charging Scheme claims need photos of each chargepoint clear enough to verify the model, serial number and the parking space it serves. Installers confirm work to BS EN 61851, BS 7671 and the IET Code of Practice, give a 3-year on-site warranty on parts and installation, and issue a BS 7671 Electrical Installation Certificate. Only OZEV-authorised installers can claim. source: GOV.UK, Workplace Charging Scheme: guidance for installers (photos, standards, warranty, certificate) |
| IET Code of Practice, 5th edition | The UK code for planning and installing EV charging equipment in homes, on-street and commercial sites. The 2023 edition aligns with BS 7671:2018+A2:2022 and ENA G12/4, adds fire safety guidance referencing RISCAuthority RC59, extends testing guidance including vehicle simulators for Mode 3, and widens the DNO notification section. source: IET, Code of Practice for Electric Vehicle Charging Equipment Installation, 5th edition (IET shop) |
| UK Smart Charge Points Regulations 2021 | Private domestic and workplace charge points sold in Great Britain since 30 June 2022 must have smart functions, default off-peak charging hours the owner can change, a randomised delay, and security in line with ETSI EN 303 645 (from 30 December 2022). Record firmware and settings at commissioning. source: GOV.UK, Regulations: electric vehicle smart charge points (Smart Charge Points Regulations 2021) |
| NEC Article 625 (US) | EV charging is treated as a continuous load. Receptacles installed to connect EV supply equipment must be GFCI protected (625.54). Equipment rated over 60 A or over 150 V to ground needs a readily accessible disconnect that can be locked open. Indoor charging may require ventilation (625.52). source: EC&M, NEC requirements for EV equipment (Article 625: GFCI, disconnect, ventilation) |
| California streamlined permitting (AB 1236, AB 970) | Cities and counties must have a streamlined EV charging permit process with a checklist online. For 1 to 25 chargers on a site, completeness is checked within 5 business days and the permit approved or denied within 20; for 26 or more, 10 and 40. Applications commonly include site plans, a single line diagram, load calculations and the manufacturer's instructions. source: California GO-Biz, Electric Vehicle Charging Station Permitting Guidebook, 2nd edition (Jan 2023, PDF) |
| OCPP | The open protocol between chargers and the charge point management system. OCPP 1.6 is still widely used, 2.0.1 adds device management and security and is not backward compatible with 1.6, and 2.1 (2025) adds bidirectional charging. OCPP 2.0.1 is IEC 63584. Record which version each charger runs; it decides what can be diagnosed remotely. source: Open Charge Alliance, Open Charge Point Protocol (OCPP 1.6, 2.0.1, 2.1; IEC 63584) |
Rules vary by state, council and contract. Checked 13 November 2026; confirm against the source for your area before relying on it.
Numbers
The numbers that set the maintenance plan
Uptime targets decide how fast a fault visit has to happen, and manufacturer schedules decide the PPM. The PPM rows are one published third-party plan for one DC model, shown as an example; use your own manufacturer's manual for each model you maintain.

Where it breaks
Where spreadsheets and generic software fall over
Leads arrive without the photos needed to price them, so someone drives out or calls back.
Make the panel, location and distance photos required on the lead form and the survey checklist, so a lead cannot move to quoting until they are there.
Fault tickets live in the helpdesk and visits live somewhere else, so the engineer cannot see the site restrictions and the office cannot see the restore time.
Create the visit from the ticket with the reference carried across, show site access and restrictions on the engineer's job, and send the status and closing note back to the ticket.
The engineer's job list does not show what to do first.
Order the list by priority and time left on the SLA, with breached and about-to-breach jobs flagged, as one maintenance manager asked for when 'engineers could look through assigned jobs and not necessarily know what needs to be addressed first'.
Checklists can be skipped, so a visit closes without the photo that proves the work.
Mark checklist items and photos as required, so the job cannot be completed until they are filled. Buyers asked exactly this: 'can we make those parts of the checklist mandatory so that they can't pass'.
Planned outages are not recorded, so the downtime is counted as a fault and the uptime report is wrong.
Keep a planned outage record per site and charger with start, end, reason and who reported it. Many maintainers are 'reliant on customers notifying us', so give the site host a link to report one.
Subcontractors are added to WhatsApp groups and see everything the customer says.
Send the sub a link to their own job, with the checklist and the notes you choose. As one installer said, 'We don't necessarily want the subcontractor to see everything that the customer is saying.'
Nobody knows which parts keep failing until the van is empty.
Deduct parts from van stock on the job and report consumption per model and site, so a run of cooling fan replacements shows up as a pattern and a reorder, not a surprise.

Software options
What software EV charger installation and maintenance companies actually use
Judge each one on whether it fits the way your jobs run, not on the feature list. Bring a real job to every demo.
Driivz
Charge point operators running a network who need a CSMS
Charging management platform with 24/7 monitoring, alerts, auto-detection, self-healing and remote diagnostics. Its operations page does not describe a field service module, so field visits usually run in another tool.
Ampcontrol
Operators and fleets wanting a CSMS with monitoring and support services
Charging software with monitoring and an alert center; its blog covers ticket management and SLA tracking for NEVI's 97% uptime. Check whether ticketing is a product or a service, and how a ticket becomes a scheduled visit.
ChargerHelp
Network owners who want to outsource O&M rather than run their own engineers
A service, not software you run: monitoring across vendors, AI diagnostics, remote-first fixes and dispatch of certified technicians under a 'Reliability as a Service' subscription.
Zendesk
Maintainers and operators who take tickets from drivers, operators and site hosts
A helpdesk is good at the conversation and the ticket, not at scheduling engineers, van stock or PPM. Most teams that use one pair it with a field service tool and need the ticket reference to round-trip.
MaintainX
In-house maintenance teams treating chargers as assets in a CMMS
CMMS with asset pages and PM plans; it publishes maintenance plans for some charger models, such as the ABB Terra 94. Check how it handles customer sites, contracts and invoicing if you maintain chargers for others.
General electrical contractor software (ServiceTitan, Simpro)
Electrical contractors for whom EV installs are one line of work
Good for quotes, jobs and invoices across all electrical work. Test them on required survey photos, a permit stage, a commissioning checklist and fault tickets with SLAs from an operator.
Questions to ask any vendor
- Can a lead or survey be blocked until the panel, location and distance photos are uploaded?
- Can a fault ticket from our helpdesk or CSMS create a visit automatically, and does the ticket reference and closing note go back?
- Can each contract have its own response and restore times, and does the engineer's list sort by time left?
- Can we record planned outages and class each outage so our uptime report is right?
- Can a subcontractor work a job from a link without seeing the customer's messages or other jobs?
- Can parts be deducted from van stock on the job and reported per model and site?

EV charger maintenance on Fieldproxy: built around how you already work
A Fieldproxy setup for EV chargers covers both halves of the business: the install pipeline from lead to commissioned asset, and the maintenance side from fault ticket to uptime report. It is built around your own survey, permit, commissioning and PPM checklists and your contracts, live within a day, with one price per company and unlimited users, and assisted migration from what you use now at no charge.
Module 1
Lead intake and remote survey
A quote without the panel photo is a guess, and a site visit to get it costs half a day.
- Lead form for homeowners, site hosts and fleets with required photos: main panel, panel rating, meter, charger location, cable route and distance
- Lead cannot move to 'Ready to quote' until every required photo is attached
- Property and site fields: building age, ownership or landlord consent, parking space served
- Map view of leads and sites
Module 2
Quotes with options
Most installs have a cheaper and a better way, and the customer should pick.
- Good, better, best options, for example install only, install with load management, install with panel upgrade
- Price list for chargers, circuits, panel work and civils
- Customer accepts online; acceptance moves the job to the permit stage
- Deposit by payment link
Module 3
Permit and DNO stage
Booking an install before the permit is approved wastes a crew day.
- Your own permit stages: pack in progress, submitted, deficiency notice, approved
- Attachments: site plan, single line diagram, load calculation, spec sheets
- Authority reference, submission and approval dates; UK DNO notification or application reference
- Rule, e.g. the install cannot be scheduled until the permit stage is Approved
Module 4
Install and commissioning checklist
The commissioning record is what proves the charger was safe and working on day one, and what a grant claim needs.
- Test results: insulation resistance, earth fault loop or GFCI, RCD trip times, polarity
- OCPP ID, CSMS connection confirmed, test charge result
- Required photos: finished unit, serial plate, parking space served, consumer unit or panel
- Customer signature and a commissioning report PDF from your own template
Module 5
Site and charger register
Every ticket and PPM visit needs the unit's history, firmware and warranty in front of the engineer.
- Sites with host contact, opening hours, access codes and restrictions
- Each charger: make, model, serial, firmware, OCPP version, power, connectors, install date, warranty end, contract
- QR code per site and per charger, so the engineer or site host scans to open the record or report a fault
- Planned outage records per site and charger: start, end, reason, reported by
Module 6
Fault tickets with SLA clocks
Uptime is lost in the gap between the ticket and the visit.
- Fault tickets from the helpdesk, the CSMS or email become visits through the open API or Zapier, with the ticket reference stored
- Response and restore deadlines per contract and priority, shown on the job
- Engineer's list ordered by priority and time left, breached jobs flagged
- Status and closing note sent back to the ticket
- Outage class on close: fault, planned maintenance, vandalism, grid or comms, with evidence
Module 7
PPM contracts
Filters and fans fail on a schedule; visits should be generated before they do.
- Service agreements per site host or operator with the chargers covered
- Recurring visits per model at the interval you set from the manufacturer's schedule (e.g. monthly checks, yearly inlet filter)
- PPM checklist per model with required items and photos
- Due and overdue PPM per contract
Module 8
Van stock and parts
A second visit because the van had no fan or connector costs a day of uptime.
- Warehouse and van stock per engineer, deducted from the job
- Reorder points and purchase orders to suppliers
- Parts consumption per model, per site and per fault type
- Warranty parts recorded against the manufacturer
Module 9
Subcontractors
Many installers and maintainers use subs in regions where they have no engineers, and need to control what the sub sees.
- Job sent to the sub as a link to that one job, with the checklist and the notes you choose to share
- Sub completes the checklist and required photos from the link, with GPS check-in
- Sub certificates and insurance with expiry dates
- Your team stays the one talking to the customer
Module 10
Reports, portal and billing
Operators and site hosts want proof of attendance and restore times, and finance wants invoices that match the contract.
- Customer portal per operator or site host: chargers, open faults, visits, reports
- Monthly report: faults, restore times, repeat faults per unit, PPM done vs due
- Invoices per contract, payment links and Stripe, two-way sync with QuickBooks, Xero or Sage
- MCP server, so the same data and actions are available from Claude, ChatGPT or Copilot, with a confirm step before changes

Straight answers
EV charger maintenance: FAQ
What software do EV charger installation and maintenance companies use?
Most use several tools: a charge point management system such as Driivz or Ampcontrol for monitoring and remote fixes, a helpdesk such as Zendesk for tickets, a field service or CMMS tool for visits, and spreadsheets for surveys, permits and van stock. Some outsource O&M to a service such as ChargerHelp. The test for any field tool is whether required survey photos, permits, commissioning, PPM, fault tickets with SLAs and van stock sit on one record per charger.
What is the EV charger uptime requirement in the US?
For chargers funded under NEVI, each charging port must average more than 97% uptime a year, calculated monthly over the previous 12 months (23 CFR 680.116). Scheduled maintenance, utility outages, vehicle faults, vandalism and natural disasters can be excluded if the operator shows the port would otherwise have worked. That is about 263 hours of allowed downtime a year per port.
What is the reliability requirement for public chargers in the UK?
Under the Public Charge Point Regulations 2023, an operator's rapid public chargers (50 kW and above) must be available 99% of the time on average across the network each calendar year, measured from OCPI statuses. Operators report to OZEV and OPSS by 14 January for the previous year, and must also run a free 24/7 staffed helpline.
What photos should an EV charger site survey include?
At minimum the main panel, the panel rating label, the meter, the proposed charger location and the cable route with the distance. Installers often add the mounting surface and the parking space. Making these required on the lead or survey means nobody prices an install without them.
What goes in an EV charger permit application?
It varies by authority, but California's GO-Biz guidebook lists site plans, a single line electrical diagram, load calculations and whether a panel upgrade is needed, a mechanical permit if ventilation is required, and the manufacturer's installation instructions. In California, AB 970 sets 5 business days to check completeness and 20 to decide for 1 to 25 chargers on a site.
What should an EV charger commissioning checklist include?
Electrical test results (insulation resistance, earth fault loop impedance or GFCI, RCD trip times, polarity), the charger's make, model, serial and firmware, its OCPP ID and confirmed connection to the CSMS, a test charge, and photos of the finished unit and serial plate. UK grant claims need photos showing the model, serial and the parking space served.
How often should EV chargers have preventive maintenance?
Follow the manufacturer's manual for each model. As one example, a published plan for an ABB Terra 94 DC charger has monthly checks of cables, connectors, screen and enclosure, monthly cleaning, yearly air inlet filter replacement and outlet filter replacement on a 1 to 2 year cycle. Busy or dusty sites usually need shorter intervals.
How do fault tickets from Zendesk or a CSMS become field visits?
The ticket should create a visit on the right charger with its SLA, carry the ticket reference, and send the status and closing note back. In Fieldproxy this runs through the open API or Zapier, and the visit holds the site access notes, checklist, parts and restore time.
How should planned outages be recorded?
As their own record per site and charger with start, end, reason and who reported it, so the downtime is classed as planned maintenance rather than a fault. Under both the NEVI rule and the UK regulations, planned maintenance can be excluded from downtime if it is evidenced.
Can subcontractors work jobs without seeing everything?
In Fieldproxy a subcontractor gets a link to one job with the checklist and the notes you choose to share, completes the required photos and readings from it, and does not see your other jobs or customers. Your team stays the contact for the customer.
Can we use Fieldproxy from ChatGPT or Claude?
Yes. Fieldproxy has its own MCP server, so anything you can do in the app, such as finding a charger's history, creating a visit or drafting an invoice, can be done from Claude, ChatGPT or Copilot, with a confirm step before anything changes.
How long does setup take?
Fieldproxy builds the setup around your survey, permit, commissioning and PPM checklists and your contracts, and the setup is live within a day. Migration from your current tools is assisted and free, and pricing is one price per company with unlimited users.
