Circuit for monitoring energy storage device, especially capacitor for safety-critical vehicle system, has arithmetic unit for determining storage device capacity by evaluating comparison circuit output signal, controlling discharge circuit
The circuit arrangement (1') has a controllable discharge circuit (6) with which the energy storage device (2) can be discharged, a precision comparison circuit (7') for comparing an electrical voltage provided by the energy storage device with two different electrical voltage values and for generating a logic output signal depending on the comparison and an arithmetic unit (12') for determining the capacity of the energy storage device by evaluating the output signal of the comparison circuit and controlling the discharge circuit.. An independent claim is also included for a method of monitoring an energy storage device, especially a capacitor for safety-critical vehicle systems.
