Abstract
A battery voltage monitoring system monitors voltage of an arrangement of more than two batteries (U, U, U, U, U) in series. The system comprises a voltage divider comprises a first (R, R, R, R) and second resistive element (R, R, R, R) arranged parallel to at least a part of the battery arrangement and connected to a reference voltage line and to a node (N, N, N, N) in the battery arrangement. In between the first (R, R, R, R) and second resistive element (R, R, R, R) a transistor (Q, Q, Q, Q) is arranged. The base of the transistor is, via a diode (D, D, D, D), connected to a further node (N, N, N, N) in the series arrangement of batteries, and a switching element (Q, Q, Q, Q) is provided to address the transistor (Q, Q, Q,Q).
