19. A method for charging and for charge monitoring of a rechargeable battery, comprising the steps of:
-
detecting a measurement signal for the rechargeable-battery current; producing a digital measurement signal from the measurement signal; processing the digital measurement signal in order to form a first current value for determining the state of charge of the rechargeable battery; processing the digital measurement signal in order to form a second current value; comparing the second current value with a reference value, and determining a difference result; producing a control manipulated variable from the difference result; and controlling a charging device for the rechargeable battery with the aid of the control manipulated variable. - View Dependent Claims (20, 21, 22, 23)
