摘要：
A battery voltage monitoring system monitors voltage of an arrangement of more than two batteries (U1, U2, U3, U4, U5) in series. The system comprises a voltage divider comprises a first (R1, R2, R3, R4) and second resistive element (R5, R6, R7, R8) arranged parallel to at least a part of the battery arrangement and connected to a reference voltage line and to a node (N1, N2, N3, N4) in the battery arrangement. In between the first (R1, R2, R3, R4) and second resistive element (R5, R6, R7, R8) a transistor (Q11, Q12, Q13, Q14) is arranged. The base of the transistor is, via a diode (D1, D2, D3, D4), connected to a further node (N2, N3, N4, N5) in the series arrangement of batteries, and a switching element (Q1, Q2, Q3, Q4) is provided to address the transistor (Q11, Q12, Q13,Q14).
