Abstract
In some examples, a circuit arrangement has a first output node for connection to a first electrode of the electrochemical cell, a second output node for connection to a second electrode of the electrochemical cell and a third output node for connection to a third electrode of the electrochemical cell. The circuit arrangement further has an interface circuit designed to output a first voltage at the first output node and further designed to output a third voltage at the third output node, which third voltage is set such that a second voltage at the second output node corresponds to a reference voltage. A control unit is designed to set the first voltage such that a predetermined cell voltage is applied between the first and the second output node. The control circuit is further designed to adjust the reference voltage depending on the electrical state of the electrochemical cell.
