  "textContent": "A method for detecting arc faults when charging electric battery systems or lead acid batteries, which are electrically connected in series to form a string which is supplied via a DC voltage converter. A first value corresponding to an electric voltage applied to the string and a second value corresponding to an electric current flowing through the string are generated. As a first condition, it is checked whether the first value changes by more than a first limit value within a first time window. As the second condition, it is checked whether the second value changes by more than a second limit value within a second time window. An arc is detected if the first condition and the second condition are met within a third time window. Provided also is a method for manufacturing electric battery systems, in particular lead acid batteries, as well as to a cut-off device.",
