TL;DR 

The Real Bottleneck: We are deploying green hardware much faster than we can maintain it, creating a massive "maintenance gap".
  • CPMS Isn't Enough: A digital CPMS will tell you a charger is dead, but it won't manage the high-voltage safety checklists, van stock or technician dispatch required to actually fix it.
  • The Execution Solution: You need a dedicated field service execution layer to bridge the gap between digital alerts and physical repairs, ensuring compliance with strict NEVI and NFPA mandates across your entire portfolio.

Here’s a question for you: What’s the single biggest threat to green infrastructure today? Surprisingly, it isn't a lack of hardware or a shortage of funding. In our experience working with operators across the country, it’s the "maintenance gap".

There’s a glaring disparity between the rapid, massive deployment of physical hardware and the maturity of the operations actually required to support it. The physical reality on the ground is stark. The public electric vehicle (EV) charging network is plagued by reliability issues, and broken chargers have become a massive, frustrating barrier to widespread EV adoption. Let’s be honest: nobody wants to roll up to a charging station on 2% battery only to find a 10,000-pound paperweight with a blank screen, right?

To achieve true operational resilience, independent charge point operators (CPOs) need far more than basic digital monitoring. The industry requires a comprehensive operating system for distributed energy resources (DERs) – one that handles the physical execution of maintenance, not just the digital alerts.

Here’s exactly why we believe the energy transition needs a dedicated field service execution layer.

Why CPMS platforms are not enough for EV charger maintenance

Charge point management system (CPMS) platforms are not enough for EV charger maintenance because they only handle the digital layer – such as billing and diagnostics – and simply cannot manage the complex physical logistics of labor, safety, and parts required to actually fix a broken unit.

Let's define the limits of the current tech stack. Most networks rely heavily on a CPMS. Platforms like ChargePoint, Driivz, and AMPECO are fantastic pieces of software, but they are purpose-built for the digital layer of the charging experience.

What a CPMS does well:

  • User authentication
  • Payment processing
  • Energy load management
  • Remote diagnostics and alerts

However, CPMS platforms are historically poor at field service management (FSM). A system can easily detect that a piece of hardware is busted. It will readily spit out an alert like "Error 404: Connector Lock Failure". But it fundamentally cannot manage the complex real-world logistics of fixing that failure.

This functionality gap is exactly where a specialized FSM execution layer steps in. By integrating with CPMS platforms via API, FieldEx becomes the "boots on the ground" execution engine. The monitoring software triggers the alert; our execution software manages the labor, the physical parts, strict service level agreements (SLAs), and the compliance documentation required to actually close the ticket.

How to manage technician dispatch and EV spare parts inventory

To effectively manage technician dispatch and EV spare parts inventory, operators must deploy an execution-focused software layer that tags technicians by specific certifications and tracks real-time van stock to prevent wasted trips.

Maintaining distributed energy assets requires a completely different approach than centralized power plants. These assets are geographically scattered, often sitting in remote or unmanned locations, and subjected to harsh environmental conditions. (Which, by the way, usually means terrible cell reception for the poor tech trying to sync their phone in a sub-basement.)

The real-world logistics problem

  • The labor problem: Can the monitoring software guarantee that the dispatched technician holds the specific "High Voltage" certification required to safely open the cabinet? No. Work orders shouldn't just go to the closest person; they must auto-assign exclusively to staff with the correct credentials, such as the Electric Vehicle Infrastructure Training Program (EVITP) certification.
  • The parts problem: Does the system know if the replacement connector cable is actually sitting in the technician's van stock before they drive 50 miles to the site? Usually not. Sending a highly-paid electrical contractor to a job without the right parts is a fast track to bleeding cash. Advanced van stock tracking ensures technicians have the necessary critical spares in their vehicle before rolling out. For more complex hardware, a 3-Tier Inventory System can track the supply chain down to the micro-level – monitoring exactly which module serial number was installed in which specific rack, and at what time.
  • The safety problem: Will the software prevent a ticket from closing until the technician has checked off a mandatory "Lockout/Tagout" safety procedure before touching live wires? Rarely.

How to meet NEVI 97% uptime mandates and NFPA safety codes

To meet NEVI 97% uptime mandates and NFPA safety codes, operators must use field service execution software to automate strict compliance reporting and enforce mandatory safety checklists before a job can be closed.

In the general trades, software adoption is usually driven by business efficiency. In the green infrastructure sector, it’s driven by compliance. In the context of critical infrastructure, downtime is not just a minor inconvenience; it’s a direct regulatory violation and a massive safety hazard.

The heavy hitters of compliance

  1. The NEVI Mandate: The $5 billion National Electric Vehicle Infrastructure (NEVI) program enforces a brutal 97% uptime requirement. Operators who fail to meet this standard risk losing millions in federal funding and face severe "clawback" provisions. Compliance demands incredibly detailed reporting on exactly why a charger was down and how it was fixed. (According to Qmerit, keeping the chargers running is only half the battle.)
  2. NFPA 855 Fire Codes: If a site includes battery energy storage systems (BESS), operational failure can lead to thermal runaway – uncontrollable fires. Strict codes like NFPA 855 (National Fire Protection Association) mandate documented Hazard Mitigation Analysis (HMA) and recurring safety inspections.
  3. The EU Battery Regulation: This mandates a "Digital Battery Passport" for industrial batteries, requiring a persistent digital record of the battery's health, its complete maintenance history, and its carbon footprint from cradle to grave.

How FieldEx helps you take on these compliance requirements

FieldEx tackles these heavy-duty compliance demands by acting as a built-in compliance engine through its Reporting & Analytics module. Instead of chasing down paperwork at the end of the month, here’s how the software handles the heavy lifting:

  • Automated NEVI Submittals: By configuring strict work order templates that mandate the collection of specific failure codes and exact repair timestamps, operators can automatically generate those complex data submittals required by the feds.
  • Ironclad Safety Logic: Checklist automation enforces rigorous safety standards. The system is built to prevent a job from closing until the technician physically verifies critical parameters – like testing gas detection sensor functionality or completing a mandatory HMA.

How to manage mixed energy portfolios (EV, solar, battery storage)

To successfully manage mixed energy portfolios containing EV chargers, solar arrays and battery storage, asset managers need a single, unified execution platform – a "Green Umbrella" – that consolidates work orders across diverse hardware brands into one dashboard.

The modern energy asset manager is rarely a specialist in just one technology anymore. Commercial developments, logistics depots, and municipal microgrids are increasingly deploying integrated systems. Commercial and industrial (C&I) solar generation, battery storage, and EV charging infrastructure are all coexisting behind the exact same meter.

Asset Class Primary Operational Driver The Current Software Gap The Execution Solution (FieldEx)
EV Charging Stations Uptime Compliance (NEVI Mandates) CPMS platforms detect faults but cannot manage physical logistics, high-voltage certifications, or parts. API-triggered dispatch, automated van stock tracking, and auto-generated uptime reporting.
Battery Storage (BESS) Thermal Safety & Fire Codes (NFPA 855) Monitoring tools track energy storage but lack physical safety workflow enforcement. Mandatory logic-driven checklists (e.g., verifying gas sensors) and immutable digital paper trails for audits.
C&I Solar Generation Yield Efficiency & PPA Adherence APM tools detect yield underperformance but cannot physically dispatch trucks or manage low-tech tasks. Unified preventative maintenance (PM) scheduling and one-dashboard visibility across mixed inverter brands.

This asset convergence creates major "fragmentation pain". Asset managers crave a "single pane of glass" that consolidates work orders across their entire mixed portfolio. Because the technician required to service a high-voltage solar inverter is very often the exact same profile of electrician required to fix a DC fast charger, the workflow simply must be unified.

Robust asset genealogy capable of tracking parent-child relationships down to the module level is no longer optional; it's a necessity for managing these mixed fleets.

The infrastructure for your infrastructure

The market data is clear. The EV charging station market is forecast to expand from approximately $40 billion to over $230 billion by 2033, with a CAGR exceeding 25%. To support a projected fleet of 27 million EVs, the US alone will see the number of charge points grow nearly tenfold by 2030.

As hardware inevitably commoditizes, the real value in this industry is shifting directly to the O&M and software layers.

Engineers and O&M directors are tired of over-promised, hyped-up tech. They want software that is so reliable, stable, and effective that it becomes virtually invisible. They want "boring but highly reliable software".

At FieldEx, we embrace that identity. We don't disrupt. We maintain. We are the execution layer that ensures the green energy transition actually works out in the real world.

The energy transition doesn't need more hype. It needs execution.

Frequently asked questions 

1. What is a CPMS? 

CPMS stands for Charge Point Management System. It is the digital software used to manage the customer-facing side of EV chargers, handling things like user authentication, billing, payment processing, and remote diagnostics.

2. Why isn't a CPMS enough for maintenance? 

While a CPMS can detect that a charger has a fault (like a broken connector), it isn't built to manage physical logistics. It can't track whether a technician has the right safety certifications, nor can it track physical inventory in a van to ensure the right replacement parts are on site.

3. What is the NEVI 97% uptime mandate? 

NEVI (National Electric Vehicle Infrastructure) is a federal program providing billions in funding for EV charging networks. To keep that funding, operators are legally required to maintain a 97% operational uptime for their chargers, meaning they can only be broken for a very tiny fraction of the year.

4. How does FieldEx help with NEVI compliance? 

FieldEx acts as a compliance engine by using automated work order templates. Whenever a repair happens, the software forces the technician to log specific failure codes and repair timestamps, automatically generating the exact reports required by the government.

5. What is EVITP certification? 

EVITP stands for Electric Vehicle Infrastructure Training Program. It is a specialized, high-voltage training and certification program for electricians installing and maintaining EV chargers. FieldEx uses Technician Skill Tagging to ensure only EVITP-certified staff are assigned to these specific jobs.

6. How does offline sync work for remote chargers?

Many energy assets are located in areas with terrible cellular reception, like underground garages or rural solar farms. Offline sync allows the software to function fully without the internet. Technicians can complete checklists, use parts, and close jobs, and the app will automatically sync all that data back to the cloud the second it finds a signal.

7. What exactly is the "maintenance gap"? 

It is the stark disparity between how fast the industry is building and installing new physical hardware (solar panels, chargers, batteries) versus how mature the operations are to actually fix and maintain them. Hardware is outpacing operational readiness.

8. What is the "Digital Battery Passport"?

Driven by the EU Battery Regulation, a Digital Battery Passport is a mandatory digital record for industrial batteries. It tracks a battery’s entire lifecycle from cradle to grave, detailing its unique identifier, chemistry, carbon footprint, and complete maintenance history.

9. Can FieldEx handle solar and battery storage as well? 

Absolutely. FieldEx is designed as a "Green Umbrella" platform to handle mixed portfolios. It consolidates work orders for Electric Vehicle (EV) chargers, Battery Energy Storage Systems (BESS), and Commercial & Industrial (C&I) Solar into one unified dashboard.

10. What is NFPA 855 and why does it matter? 

NFPA 855 is a strict standard created by the National Fire Protection Association detailing the installation and safety codes for stationary energy storage systems (like massive lithium-ion batteries). FieldEx uses logic-driven checklists to ensure technicians document mandatory fire hazard and ventilation inspections required by this code.
