EVA England and ClearWatt Partner to Boost Used Electric Car Buying Confidence Through Advanced Battery Diagnostics
Key Insights
EVA England has partnered with ClearWatt to enhance consumer confidence in the used electric vehicle market by providing accessible battery health diagnostics.
ClearWatt's new smartphone app offers real-time performance data and over 50 supplementary data points to predict EV battery capacity without direct car computer access.
The collaboration aims to mitigate unfounded concerns about long-term EV battery health, which have historically hindered used EV market growth.
Executives from both organizations emphasize that increased transparency and data-driven insights are crucial for accelerating electric vehicle adoption across all market segments.
EVA England, the leading association for electric vehicle drivers, has announced a strategic partnership with ClearWatt, an innovative EV testing and analytics firm. This collaboration, effective June 30, 2025, aims to significantly bolster buyer confidence in the burgeoning used electric car market by providing members with direct access to ClearWatt’s advanced diagnostic technology. The initiative is poised to accelerate the transition to electric vehicles by making pre-owned EVs a more attractive and transparent option for consumers across the United Kingdom.
The core of ClearWatt’s offering is a proprietary smartphone application designed to demystify EV battery health and performance. Unlike some existing battery testing software, such as those utilized by dealers like Generational, which require direct communication with a vehicle's onboard computer, the ClearWatt app operates solely via a smartphone. This streamlined approach significantly lowers the barrier to entry for comprehensive EV health analysis, making it accessible to individual buyers and sellers. The application provides real-time performance data, augmented by over 50 supplementary data points, to generate accurate predictions of battery capacity and overall vehicle health. Beyond technical diagnostics, the app also furnishes users with practical insights into charging costs—both home and public—and road tax implications, offering a holistic view of EV ownership economics.
The used electric vehicle market has experienced substantial growth over the past year, yet persistent, often unfounded, concerns regarding the long-term degradation of EV batteries have continued to impede broader adoption. ClearWatt and EVA England believe that by delivering clear, data-backed figures, their partnership will effectively alleviate these anxieties, thereby stimulating further uptake in both the new and used EV sectors.
Patrick Cresswell, Co-Founder and Managing Director of ClearWatt, emphasized the shared vision, stating, “We’re proud to be joining EVA England as a partner. They are a powerful voice for EV drivers across key stakeholders including central government, and we share the same mission: to make electric vehicle ownership simpler, smarter, and more transparent. Battery health and uncertainty about EV performance remain some of the most important – and misunderstood – factors in used EV buying. By working together, we can give drivers the clarity and confidence they need to make better decisions and accelerate the shift to electric.”
Dr. Vicky Edmonds, CEO of EVA England, echoed this sentiment, highlighting the direct impact on consumers. “We hear time and again from drivers that battery uncertainty is one of the biggest barriers to buying a used EV,” Dr. Edmonds commented. “Our partnership with ClearWatt will help tackle that head-on, giving consumers the information they need to make confident, informed decisions. Their transparent, data-led approach is exactly what the market needs, and we’re proud to be working alongside them to help give drivers greater confidence in second-hand EVs.” This collaboration marks a significant step towards fostering a more robust and trustworthy secondary market for electric vehicles, crucial for achieving widespread EV adoption goals.
