Concerns Rise Over Ultra-Fast Charging Impact on EV Battery Life

The rapid development of ultra-fast charging technology for new energy vehicles, expected to surge in 2025, is easing range anxiety but has sparked concerns about accelerated battery degradation and reduced lifespan. Industry analysis and user reports indicate that frequent use of ultra-fast charging, especially in high-mileage vehicles like ride-hailing cars, can significantly shorten battery life, with studies showing up to a 40% reduction in battery cycle life compared to slow charging. Consumers are further worried due to the high cost of battery replacement, sometimes equaling half the price of a new vehicle, which complicates decisions around repair versus replacement. Although regulations in China require automakers to provide lengthy battery warranties, the practical application of these warranties is often complex. These developments highlight the need for careful consideration of charging habits and greater transparency from manufacturers regarding warranty terms and long-term battery durability.
