Study reveals low battery degradation in electric vehicles

Study uncovers surprising facts about ev battery health

A recent study by British firm Generational has brought welcome news to electric vehicle (EV) owners and potential buyers alike. The analysis of over 8,000 EVs found that the average battery health stands at a remarkable 95.15% compared to the vehicle's original capacity.

Age and mileage not key factors in degradation

Contrary to common assumptions, the study revealed that vehicle age and mileage do not have a significant impact on battery degradation. Even vehicles with over 160,000 miles recorded a battery capacity of between 88% and 95%.

Battery health more dependent on usage than age or distance

Generational's research highlighted that other factors, such as intensive rapid charging, exposure to extreme temperatures, and allowing the battery to drop too low, can be much more detrimental to battery health than age or mileage.

Study finds low degradation rates across vehicle ages

• Newer vehicles, aged 0-3 years, showed an average battery health of 96.94%
• Vehicles 3-4 years old averaged 95.17%
• Even those 8-12 years old maintained a respectable 85% battery health

Implications for second-hand ev market

The study's findings should alleviate concerns among consumers considering purchasing used EVs. Generational notes that the current low degradation rates mean owners can expect their batteries to retain much of their original capacity, reducing the need for costly replacements.
