Mileage doesn't tell the whole battery story

Age and mileage alone cannot tell you how an EV battery has been used or how it is performing today. Battery condition is influenced by charging habits, driving behaviour, age and factory variation. Two vehicles with the same mileage can have very different batteries.

Generational gives your team vehicle-specific evidence before buying, pricing and selling.

Usage and charging

How a vehicle has been used and charged can affect battery condition, long-term performance and resale confidence.

Placeholder Image-1

Driving behaviour

Vehicle driving style and operating conditions can influence degradation, efficiency and the battery’s long-term value.

Placeholder Image-2

Vehicle variation

Battery condition does not follow a fixed pattern. Vehicles of the same age and mileage can perform very differently.

CELL VOLTAGE IMBALANCE

Go beyond a headline State of Health figure

A single State of Health percentage does not always tell the full story of an EV battery. 

Two vehicles can return a similar overall score while the condition of the individual cells within each battery pack is very different.

That is why Generational combines State-of-Health with cell-level diagnostic checks. By highlighting inconsistencies between cells, retailers gain a clearer view of battery condition and can identify potential issues that a headline percentage alone may miss. It supports better-informed decisions when buying, appraising, pricing and selling used EVs, while giving customers stronger evidence about the vehicle they are considering.
