Abstract
An electrical circuit that enables a determination of a first voltage present inside a battery cell includes an oscillating circuit having a coil and a component, the electrical capacity of which depends on the voltage present on the component, and a reference electrode. The component can be a varactor diode. A method for determining a first voltage which is present within the battery cell and an arrangement having an additional electrical circuit outside the battery cell housing for reading out the first voltage present inside a battery cell are also provided.
