China mandates EV batteries must remain with vehicles upon scrapping

China has mandated that electric vehicle (EV) power batteries must remain with the vehicle upon scrapping, effective April 1, 2026. This regulation aims to prevent discarded batteries from entering uncontrolled channels, as the volume of waste power batteries is projected to exceed one million tons annually by 2030. Manufacturers are responsible for recycling the batteries they produce or import, and old EVs without batteries will be classified as incomplete vehicles. The move addresses growing concerns over battery disposal as the EV industry expands.
