Always-On, Always Reliable: TEAL Redefines EV Charging Connectivity

Electric vehicle (EV) charging reliability has been a significant barrier to EV adoption, since the beginning of America’s exciting EV revolution. A recent study by J.D. Power showed that reliability is improving, although far from solved. Another recent industry analysis revealed that over 55 percent of EV charging failures come from stations failing to connect to their network. EVinfo.net spoke with Robb Monkman, Chief Marketing Officer at leading connectivity company TEAL, about how his company is solving the EV charging reliability issue.

J.D. Power’s latest 2025 U.S. Electric Vehicle Experience (EVX) Public Charging Study shows a notable drop in failed charging attempts, with only 14 percent of EV owners unable to charge at public stations, down from 19 percent in 2024. J.D. Power released the study on August 13, 2025.

This marks the lowest failure rate in four years, suggesting that reliability is slowly improving. Yet this statistical progress doesn’t tell the full story, and it certainly hasn’t erased consumer concerns. Despite fewer outright failures, overall satisfaction with public charging is declining.

The J.D. Power study found that satisfaction with DC fast chargers slipped to 654 on a 1,000-point scale, a 10-point decrease from the same period a year ago. Satisfaction with Level 2 chargers dropped to 607, a 7-point decrease year over year. The problem isn’t just whether chargers work, it’s how much they cost and how frustrating they are to use, the study found.

The takeaway is clear. Reliability may be improving, but satisfaction is falling, and a poor consumer experience has become the defining barrier to wider EV adoption. Until charging becomes not only available but also reliable, affordable, transparent, and effortless, skepticism will linger, and EV adoption rates will suffer.

For automakers, policymakers, and charging providers, the challenge now is not just to build more chargers but to deliver an experience that builds confidence every time a driver plugs in. Reliability is one of the most important cornerstones of a fully optimized EV charging landscape that would drive mass EV adoption, bringing lower costs to drivers, and cleaner air for all. Connectivity is at the heart of reliability, and TEAL has a compelling and effective solution.

Over 55% of EV Charging Failures Are Due to Connectivity Issues

Imagine pulling up to a public EV charging station, plugging in your car, and then… nothing happens. You patiently wait, but the charger doesn’t authorize your session. The screen freezes, the app times out, or the payment doesn’t process. It’s not a broken plug or a damaged cable, it’s often a lack of network connectivity. Astonishingly, a recent industry analysis reveals that over 55 percent of EV charging failures trace back to stations failing to connect to their network for authentication and transaction processing.

Chargers typically rely on a single cellular connection to communicate with central systems. When this connection falters due to poor cell reception, modem failure, or power loss, the station can’t verify payment or authorize a session, even if the hardware itself is in perfect condition.

This connectivity dependency exposes a critical vulnerability: more than half of charging failures aren’t caused by mechanical breakdowns but by digital disconnection.

These statistics highlight a pressing and underestimated challenge within the EV ecosystem: charging stations don’t just need to work; they must stay reliably connected. When they don’t, users face frustrating, unpredictable experiences that can erode confidence, even in the absence of broken hardware.

This reality contributes to “charging anxiety,” the fear of not being able to charge seamlessly when needed. Beyond battery range or access to chargers, these everyday tech glitches undermine the broader promise of electric vehicle convenience.

EVinfo.net Interviews Robb Monkman, Chief Marketing Officer at TEAL

We had the great honor of speaking with Robb Monkman, Chief Marketing Officer at TEAL, about TEAL’s solutions for EV charging reliability.

Bill Pierce:

Reports show that more than 1 in 5 EV charging stations don’t work at any given time. Why is this such a big issue for EV adoption?

Robb Monkman:

This is one of the biggest barriers holding back the EV industry. Imagine being an EV driver and pulling up to a station that looks ready to charge, only to find out it’s offline. That kind of experience creates frustration, delays, and a loss of confidence in the entire ecosystem. Reliable charging is fundamental to addressing “range anxiety.” If drivers can’t trust that stations will work when they arrive, adoption slows down regardless of how advanced EV technology becomes.

Bill Pierce:

What’s causing so many charging stations to fail?

Robb Monkman:

Surprisingly, over 55% of failures are due to connectivity issues. Charging stations rely on cellular networks for critical functions: authenticating payments, transmitting operational data, and updating availability in real-time. When connectivity fails, the charging station becomes unusable, even if the hardware is fine. It’s not just an inconvenience, it’s a systemic reliability problem.

Bill Pierce:

How does TEAL’s Network Orchestration Service (NOS) solve this connectivity challenge?

Robb Monkman:

TEAL flips the script by giving charging stations carrier freedom and redundancy. With our NOS (Network Orchestration Service), a charger isn’t locked into a single carrier. If one network goes down, the station can automatically switch to another available network all over-the-air, without the need to swap out a SIM card. That means chargers stay online, drivers stay happy, and operators don’t have to worry about downtime.

Bill Pierce:

What are the key benefits for EV charging operators?

Robb Monkman:

There are several:

Always-on connectivity because chargers can connect to the best available carriers in 196 countries.

Simplified management because one eSIM from TEAL replaces dozens of contracts, SIMs, and provider relationships.

Fast Deployment as chargers can be provisioned remotely, over-the-air, without manual SIM swaps or site visits.

Operational efficiency from less downtime, fewer truck rolls, and lower maintenance costs.

The bottom line: operators can scale faster, cut costs, and provide a better experience to drivers.

Bill Pierce:

And what about the drivers, how does this impact them directly?

Robb Monkman:

For drivers, it’s about trust. No one wants to gamble on whether a charger will be operational. TEAL ensures stations are always connected, which translates into more reliable charging experiences. When stations work consistently, range anxiety goes down, confidence goes up, and adoption accelerates.

Bill Pierce:

Why is connectivity so fundamental to the future of EV adoption?

Robb Monkman:

EV adoption isn’t just about making cars with longer battery range, it’s about ensuring the infrastructure works. Without reliable charging stations, we risk stalling the momentum of electrification. Connectivity is the invisible backbone of EV charging. If we get that right, we remove a massive barrier to adoption and make the EV ecosystem as dependable as filling up at a gas station.

Bill Pierce:

What role do you see TEAL playing in the modernization of EV infrastructure moving forward?

Robb Monkman:

TEAL’s NOS offers unmatched reliability and scalability for EV charging operations. With TEAL, charging station operators can access any global cellular network on demand via a single pane of glass, streamlining logistics and simplifying operations.

This always-on connectivity is what makes charging infrastructure dependable, scalable, and future-proof.

Bill Pierce:

How does TEAL enable faster installation and deployment of EV charging stations?

Robb Monkman:

One of the biggest challenges for charging operators is figuring out which carrier will work best at each site. Traditionally, that meant site surveys, juggling multiple SIM cards, and negotiating contracts with different providers. TEAL eliminates all of that. With our NOS, operators can simply ship, install, and connect. Once online, the charger automatically connects to the strongest available network over-the-air, no site survey required.

We also offer Bring Your Own Carrier (BYOC), which allows operators to bring their existing carrier agreements onto the TEAL platform.

This means you can keep your current contracts while also dynamically expanding onto any global network as needed. BYOC puts operators securely in the driver’s seat, giving them the flexibility to switch and monitor devices on any worldwide network without renegotiating with each carrier individually.

Finally, our next-gen connectivity management platform, Aurora, is designed to adapt to deployments of any size. Whether you’re rolling out dozens or thousands of chargers, TEAL enables operators to scale faster, reduce costs, and simplify operations.

Bill Pierce:

Will TEAL be attending any upcoming industry events?
