The last few months have made one thing very clear: ClearWatt is being adopted across more parts of the EV market than ever before.
On the consumer side, we have launched partnerships with Zapmap and Zoom EV, helping more drivers access ClearWatt’s battery health and real-world EV performance tools through platforms drivers already use and trust. Across the retail market, adoption of our hardware-enabled EV testing and reporting continues to build, with new dealer groups coming on board regularly, including Car360, one of the UK’s most EV-focused retailers, and a 40+ location AM20 dealer group. These sit alongside a growing portfolio of franchise dealer groups, car supermarkets and independent EV specialists now using ClearWatt, reflecting broad acceptance right across the retail market. Beyond conventional vehicle retail, we are also working with recell.store to support battery health testing in salvage and second-life battery use cases, where better evidence around battery condition can help unlock more value from EV batteries beyond the first life of the vehicle.
That range of activity is exciting because it shows the breadth of the business we have been building from day one.
ClearWatt is often described as a battery health app, and that is still an important part of what we do, but it is only one expression of a broader capability. At its core, ClearWatt turns EV data into practical answers that help people buy, sell, value, manage and understand electric vehicles with more confidence.
That matters because EVs are data-rich assets, but the market does not need more raw data. Consumers, retailers, platforms, finance providers, insurers, fleet operators and specialist battery businesses all need something more useful: trusted evidence, interpreted properly, and presented in a way that supports a real decision.
The same need appears in different places
The used EV market is still working through a confidence gap.
A driver might worry that their car is not delivering the range it should. A buyer might hesitate over a used EV because they do not know how to judge the battery. A dealer might be unsure how to appraise, price or explain an electric vehicle on the forecourt. A marketplace might want better information on a listing. A finance or insurance provider might want clearer visibility of the asset. A salvage or second-life operator might need to understand whether a battery still has useful value.
Those may sound like different problems, but they are all versions of the same underlying question: how do we understand this EV properly?
Mileage, age and service history still matter, but they do not tell the whole story. Dashboard range is often misunderstood, and can move around because of temperature, driving style, route, tyres, recent usage and software behaviour. Battery data can be difficult to access, inconsistent between manufacturers and easy to overinterpret when taken out of context. Even when useful data exists, most people do not want a stream of numbers; they want to know what those numbers mean.
That is where ClearWatt fits.
We collect, analyse and interpret EV data from different sources, including connected vehicle data, real-world driving and charging behaviour, diagnostic reads where appropriate, vehicle configuration and model-level expectations. Not every use case needs every data source, but the principle is the same: stronger evidence leads to better answers.
For drivers, it means understanding their own EV
The ClearWatt app gives EV drivers a way to understand battery health, range and real-world performance without needing to become battery engineers.
Some people use the app before selling their car, because they want independent evidence that the vehicle has been assessed properly. Others use it after buying, because they want reassurance that the car is performing as expected. Some use it because they suspect there may be an issue. Others are simply curious about how their EV behaves in the real world.
One recent example shows how this can play out. A driver came to ClearWatt wanting an independent, third-party view of their car’s performance: their dealer had told them the vehicle was behaving normally, but they suspected otherwise. Our app-based assessment put clear numbers against the issues they had noticed and confirmed there was a genuine problem. We then supported them in raising it with the manufacturer, who resolved it through a software update.
“I wanted an independent third-party assessment of my car’s performance because the dealer told me the car was normal and I suspected otherwise. ClearWatt gave me an app-based assessment of the car and its performance and could put some numbers next to the issues I had noticed. Fortunately the problem was fixed by the manufacturer after a software update. ClearWatt were always very helpful and responsive, and I wouldn’t hesitate to use them again — particularly if I was buying a used electric car and wanted some reassurance around battery performance.”
That direct consumer relationship is important because it gives us a live view of the questions EV drivers are actually asking, rather than the questions the industry assumes they are asking.
One insight we are now seeing clearly through the app is that concern about EV performance is often much higher than the underlying issue rate. In recent app data, around 18% of drivers adding their EV to ClearWatt told us they were doing so because they believed there might be a problem with the car, while only around 1% of completed assessments showed a result that required further investigation.
The exact numbers will continue to develop as the dataset grows, but the pattern is important. A meaningful share of EV uncertainty is not caused by failing batteries; it is caused by the absence of clear, trusted evidence.
That does not make consumer concern irrational. EV behaviour can be difficult to interpret, and range can change significantly depending on conditions. The point is that confidence requires more than generic advice or a dashboard estimate. Sometimes the value of ClearWatt is identifying a genuine issue, but often the value is showing that a vehicle is performing normally and giving the owner the confidence to act on that evidence.
For retailers, it means better evidence at the point of sale
The same need appears in a different form for dealers.
Retailers are being asked to stock, appraise and sell vehicles where the most valuable component is also the least familiar to many buyers. That creates practical challenges. How should an EV be valued? How should battery condition be explained? What should happen if a customer asks whether the range is normal? What evidence can a sales team use to build confidence without overcomplicating the buying journey?
ClearWatt’s dealer proposition is designed to answer those questions in a way that fits the retail environment.
Depending on the vehicle and use case, that might mean a two-minute hardware-enabled spot test, an app-based assessment, a charging test, an independent drive test or a combination of methods. Some EV experts and dealer groups use ClearWatt’s diagnostic and charging tests together, because different data sources can answer different questions and provide a more complete view of the vehicle.
The output is not intended to bury retailers or customers in technical detail. It is designed to provide a clear, independent view of battery condition and real-world EV performance, with the supporting evidence needed to appraise, prepare, advertise and sell the vehicle more confidently.
That is why dealer adoption has continued to build. Retailers do not need EV testing as a theoretical exercise; they need it because it helps solve real commercial problems around valuation, sales confidence, customer education and post-sale reassurance.
For partners, it means EV intelligence inside existing journeys
Not every ClearWatt use case requires the end user to open the ClearWatt app or read a standalone report.
For platforms, marketplaces and other partners, the value is often in bringing EV intelligence into journeys that already exist. That could mean battery confidence indicators, real-world range insight, vehicle condition data, charging or usage context, or clearer explanations that help a customer make a decision at the right moment.
A marketplace may want better EV information on a listing. A consumer platform may want to help drivers understand whether their car is performing normally. A finance or insurance provider may want clearer visibility of the asset it is supporting. A fleet operator may want to understand long-term condition and usability across vehicles. A salvage or second-life operator may want evidence that helps determine whether a battery should be repaired, reused, redeployed or recycled.
In those cases, ClearWatt acts as a data and intelligence layer that can sit behind the partner’s own customer experience.
That is an important part of how the business fits together. The consumer app, dealer reports, hardware-enabled tests and partner data services are different routes to the same destination: better EV decisions, backed by better evidence.
Why battery health sits at the centre
Battery health is central to ClearWatt because it remains one of the biggest trust questions in the EV market.
But battery health should not be treated as a single isolated number with no context. A credible view of an EV depends on multiple signals, including usable capacity, voltage behaviour, cell balance, charging patterns, efficiency, temperature, software limits, vehicle configuration and real-world performance. The challenge is not simply accessing one data point; it is understanding which data matters, how reliable it is, and how it should be explained to someone making a decision.
That is the difference between raw data and useful intelligence.
The business we have been building from day one
The recent momentum across consumer partnerships, dealer adoption and second-life battery use cases is a strong validation of the ClearWatt approach.
Consumers need confidence in the EVs they own. Retailers need trusted evidence when appraising, preparing and selling used EVs. Platforms need EV intelligence that can sit naturally inside their own customer journeys. Specialist operators need reliable ways to assess condition and value as batteries move through repair, salvage, reuse and second-life applications.
ClearWatt sits across those use cases because the underlying need is the same.
The EV market does not need more guesswork, more jargon or more disconnected data points. It needs clear, trusted ways to understand vehicle condition, battery performance and real-world usability.
That is what ClearWatt is building.
For some people, that will continue to mean the app. For others, it will mean dealer testing and reporting. For partners, it will mean data services and intelligence embedded into existing journeys. For specialist operators, it will mean evidence that supports better decisions around battery value and reuse.
Different parts of the market may come to ClearWatt in different ways, but the purpose is consistent: to make EVs easier to understand, easier to trust and easier to buy, sell, own, manage and redeploy.
The last few months have been a big step forward on that mission, and without giving too much away, the rest of the year is shaping up to be even more exciting.
