Summary

Are electric vehicle batteries really destined to age rapidly and lose their value? This in-depth study dives into the data to break down common misconceptions about EV battery degradation. Despite claims of swift capacity loss, an analysis of over 7,000 EVs reveals a striking reality: most batteries tested retain more than 85% of their original capacity even after reaching impressive 300,000 kilometers on the road, far outperforming common expectations. 

Thanks to continuous advances in battery chemistry, thermal management, and battery management systems, manufacturers have gained confidence in the longevity of EV batteries and therefore extend warranties substantially. This reliability reassures consumers, knowing that their investment in an EV is solid and likely to sustain value long term.

But the story doesn’t end when the battery’s life on the road ends. Many of these batteries retain significant residual value, finding second lives as stationary energy storage or being recycled to recover valuable materials like lithium and nickel. This not only provides economic benefits but also supports a sustainable lifecycle for critical resources, reinforcing consumer trust and driving the transition to electromobility with a clear focus on both performance and environmental impact.
