Abstract
The disclosure relates to a method and an arrangement for diagnosing drivers of contactors, to a battery, and to a motor vehicle having such a battery. According to the method, information relating to switching states of at least three drivers of a contactor is stored, with information relating to respective associated desired values of at least one predefinable parameter, in a computer-readable memory. Actual switching states of at least some of the drivers are detected with associated actual values and are compared with the stored desired values in order to diagnose the drivers. A fault is diagnosed if at least one actual value differs from a desired value.
Claims10
A method for diagnosing drivers of contactors, comprising:
- storing information in a computer-readable memory relating to desired switching states of at least three drivers of a contactor, wherein the information relates to respective associated desired values of at least one predefinable parameter;
- detecting actual switching states of at least some drivers of the at least three drivers, wherein the actual switching states are associated actual values;
- comparing the actual values with the desired values in order to diagnose the drivers;
- and
- diagnosing a fault if at least one actual value differs from a desired value.
An arrangement comprising:
- a contactor;
- at least three drivers associated with the contactor;
- a data processing unit;
- and
- a memory device,
- wherein the arrangement is configured to perform a method for diagnosing the at least three drivers associated with the contactor,
- wherein the method includes
- storing information in the memory device relating to desired switching states of the at least three drivers, wherein the information relates to respective associated desired values of at least one predefinable parameter,
- detecting actual switching states of at least some drivers of the at least three drivers, wherein the actual switching states are associated actual values, comparing the actual values with the desired values in order to diagnose the drivers, and
- diagnosing a fault if at least one actual value differs from a desired value.
A motor vehicle comprising:
- an electrical drive motor configured to drive the motor vehicle;
- a battery configured to be connected to the electrical drive motor;
- and
- an arrangement including (i) a contactor, (ii) at least three drivers associated with the contactor, (iii) a data processing unit, and (iv) a memory device,
- wherein the arrangement is configured to perform a method for diagnosing the at least three drivers associated with the contactor,
- wherein the method includes
- storing information in the memory device relating to desired switching states of the at least three drivers, wherein the information relates to respective associated desired values of at least one predefinable parameter,
- detecting actual switching states of at least some drivers of the at least three drivers, wherein the actual switching states are associated actual values,
- comparing the actual values with the desired values in order to diagnose the drivers, and
- diagnosing a fault if at least one actual value differs from a desired value.
