Kerry Dunstan and his partner recently purchased a 2021 Nissan Leaf, a decision largely influenced by the battery’s state of health (SOH), which was reported to be around 93%. The vehicle, which cost £12,500 and had 29,000 miles on the odometer, is noted for its spaciousness despite Dunstan’s mixed feelings about its performance compared to more stylish electric cars.
As electric vehicle (EV) ownership increases, buyers are increasingly concerned with the condition of the battery, shifting the focus away from traditional factors such as mileage. The way a battery is maintained, including practices like frequent fast charging, can significantly impact its longevity. However, battery analytics firms claim to provide accurate assessments of a used EV’s battery health. Some experts suggest that older models, such as the Nissan Leaf, may experience accelerated range declines over time, particularly those without advanced cooling systems.
For prospective buyers with concerns about battery condition, companies like Aviloo offer battery health assessment services. Their premium test allows car owners to monitor battery performance over several days, while a quicker flash test can analyze battery data in under two minutes. Aviloo’s reports often differ from internal vehicle analytics, indicating a need for consumers to seek independent assessments.
Additionally, consumers like Lucy Hawcroft have experienced unexpected decreases in battery health after purchasing used EVs. Questions about the best charging practices for extending battery life remain, with suggestions indicating a balance between frequent fast charging and avoiding it altogether.
Advancements in battery technology have been significant, with newer batteries achieving more charging cycles compared to older models. Thus, even batteries that no longer serve their original purpose may find utility in other applications, such as energy storage. As the industry evolves, a call for more standardized methodologies for reporting battery health is evident.
