Generational has launched a digital Logbook that embeds battery State of Health, real-world range, charging and running-cost data directly into used EV listings, with Available Car as its first customer. The UK battery-diagnostics company says the tool is designed to close the gap between consumer interest in EVs and online purchase consideration by answering buyers’ most common questions before they inquire, reserve or visit a showroom. The Generational Logbook debuts on the website of Available Car, which the company describes as the largest used-car supermarket — a high-volume used-vehicle retailer — in England’s East Midlands.
Highlights
- 95.15% average State of Health across more than 8,000 UK used-EV battery assessments in Generational’s 2025 Battery Performance Index, with variance widening as vehicles age
- 65% of UK drivers believe EV total cost of ownership exceeds that of internal-combustion vehicles, according to a Cox Automotive survey of more than 2,000 drivers cited by Generational
- Three modules in one listing-page tool: a Battery Health Report, an interactive EV Range Map and a Running Cost Calculator
- Available Car is the launch customer, with the Logbook live on its used-EV listings
What the Generational Logbook Shows Buyers
Retailers can add the Logbook directly to vehicle listing pages on their own websites. According to Generational, it gives prospective customers vehicle-specific information on battery condition, real-world range, charging and running costs at the point of online discovery — before an inquiry, a reservation or a dealership visit.
At the core of the tool is Generational’s Battery Health Report. The company says it includes:
- Battery Health Certificate for the specific vehicle
- State of Health percentage measured against original capacity
- Original battery capacity
- Remaining battery warranty details
Generational says these data points let retailers move buyer insight beyond age, mileage and headline range to what it calls the vehicle’s most valuable component.
How Does the EV Range Map Work?
The Logbook’s interactive EV Range Map provides a visual reference for how far a customer could travel on a full charge. Generational says the map uses the vehicle’s effective range and lets users toggle by season, choose between one-way and round-trip journeys on a single charge, and view charging points relative to a chosen starting location.
The company positions the map as a way to turn range from an abstract figure into a practical planning tool, showing how a specific vehicle fits a customer’s real-world journeys rather than relying on quoted mileage alone.
Running Cost and Charging Time Calculators
A Running Cost Calculator lets customers compare the indicative cost of driving an EV against a gasoline-powered car. Users can adjust annual mileage, the split between home and public charging, home and public charging prices, fuel cost and MPG. The tool then returns an indicative estimate of annual savings and cost per mile.
A separate calculator estimates weekly charging time, with adjustable inputs for annual miles driven and the home-versus-public charging split. Generational says this is intended to demystify charging behavior for buyers new to EV ownership.
The Confidence Gap in Used EV Sales
Generational frames the launch around consumer-education research. The company cites Cox Automotive’s 2026 UK EV Adoption and Perceptions Report, based on a survey of more than 2,000 UK drivers, which found that cost perception, battery myths and charging confidence remain among the most significant barriers to adoption. The same report identified clearer battery health, degradation and warranty information as key levers for narrowing that gap, and found that 65% of UK drivers believe EV total cost of ownership is higher than for internal-combustion vehicles despite many EV owners citing lower maintenance costs.
Generational’s own 2025 Battery Performance Index, drawn from more than 8,000 battery health assessments across the UK used-EV market, put average State of Health at 95.15%, with many older and higher-mileage vehicles performing strongly. The Index also found that variance between vehicles increases with age — which the company says reinforces the case for testing on a case-by-case basis rather than relying on fleet averages.
The Logbook follows Generational’s partnership with Maverick Diagnostics earlier this year to bring its battery testing into UK workshops, and arrives as survey data continues to show that used EV buyers prioritize battery health data when weighing a purchase.
What Generational and Available Car Say
Oliver Phillpott, CEO of Generational, said: “The used EV market is in need of more information for car-buyers. Customers are interested in electric vehicles, but they often need clearer answers around battery life, range, charging and cost before they feel ready to take the next step. For instance, something as simple as seeing how far you can actually get on 200 miles’ range, when viewed on a map, really helps break down confidence barriers.
“The Generational Logbook is designed to put those answers directly on the vehicle listing, where customers are spending time weighing up their options. By bringing together battery health, warranty detail, usable range, charging context and running costs in one digital tool, retailers can make EV ownership feel more tangible before a customer even walks into a showroom.”
Steve Wiseman, Operations Manager at Available Car, said: “Used EVs are still new territory for a lot of customers, so it’s understandable that people want a bit more information before they commit. For us, the value of Generational’s Logbook is that it gives customers useful, vehicle-specific information at the point they are already browsing. It should help them understand what a particular EV might cost to run, how far it will go and what condition the battery is in. That can only help people feel more comfortable and better informed when they are deciding which used EV is right for them.”
Phillpott added: “Used-EV customers need the same level of confidence they have come to expect from service history, mileage verification and vehicle checks. The difference is that EVs require a new layer of information, from battery condition and usable range to charging behaviour and running costs.
“The retailers that can make that information clear online will be best placed to convert EV interest into sales. The Generational Logbook gives them the tool to do exactly that.”
Retailer Positioning
For retailers, Generational says the Logbook supports EV merchandising, conversion and inquiry quality by presenting ownership information in a single accessible format on the listing. The company’s existing battery health checks and State of Health certification already serve retailers, leasing companies and remarketers assessing used EV batteries for appraisal, valuation and resale.
