description Various aspects of the present disclosure are directed to a method for ascertaining the state of health of a secondary battery. In one example embodiment, the method includes making a first estimation for the state of health by an observer, using an aging prediction model to ascertain a second estimation for the state of health, the aging prediction model being parameterized on the basis of the first estimation for the state of health. The first or second estimation of the state of health, or a combination of the first and second estimation of the state of health, is used as the state of health of the secondary battery.
