Abstract
A method and an exhaust-gas treatment device for regenerating an exhaust-gas purification component include charging at least one capacitor and heating at least one sub-volume of the exhaust-gas purification component to at least 900° C. by supplying at least a part of the energy stored in the capacitor. A particle burn-off reaction can be started from the at least one sub-volume for a large volume of exhaust-gas purification components. Exhaust-gas purification components in an exhaust system of an internal combustion engine can thus be completely regenerated in an energy-efficient manner. A vehicle having the exhaust-gas treatment device and carrying out the method is also provided.
