Abstract
A monitoring circuit is provided for an energy storage device. The energy storage device has a plurality of cells which each provide a voltage between their first and second connections and are switched in series. At least two voltage measuring circuits are provided, wherein the voltage measuring circuits each measure the voltage between a first measurement input and a second measurement input. A first connection conductor connects the first terminal of the first cell to the first measurement input of a first voltage measurement circuit. A second connection conductor connects the second terminal of the first cell to the second measurement input of a first voltage measurement circuit. A first load resistor can be switched between the first measurement input of the second voltage measurement circuit and a first fixed potential.
