Abstract
A method includes adjusting a rechargeable battery from a first state of charge to a second state of charge; creating a first current intensity value after a first predetermined time duration has elapsed, after a predetermined temperature value has been reached, after a predetermined current intensity value has been reached, or if the difference between a first and a second ascertained current intensity value reaches a predetermined threshold value; ascertaining a first voltage value after the first current intensity value has been reached; adjusting a second current intensity value after a second predetermined time duration has elapsed; ascertaining a second voltage value after the second current intensity value has been reached; and determining a first impedance value of the rechargeable battery from the quotient of the difference between the first and second current intensity values and the difference between the first and second voltage values. Rechargeable battery and charger for carrying out the method.
