An electric vehicle owner in Britain is challenging the widely followed "80% rule," which suggests drivers should only charge their EVs up to 80% to preserve battery health. The owner argues that modern battery technology and real-world usage patterns make this guideline unnecessary, allowing drivers to charge fully without significant long-term damage. Industry experts increasingly question whether the rule still applies to newer models, as advancements in battery chemistry and smart charging systems reduce wear concerns. The debate highlights shifting perspectives on EV maintenance as adoption grows.
