Original Abstract Submitted
A computer system includes processing circuitry configured to provide a characterization model for each one of a plurality of contactors of a switching arrangement, each contactor being configured to connect and disconnected an associated battery pack of an energy storage system of a vehicle by closing and opening, respectively, the characterization model defining contactor wear for contactor opening with regards to a plurality of system parameters, the system parameters comprising at least current and voltage during contactor opening, determine the system parameters during operation of the switching arrangement, estimate, for each one of the contactors, the contactor wear by applying the determined system parameters to the corresponding characterization model; control the order in which the contactors are opened in response to the estimated contactor wear, and/or predicting maintenance of contactor, or contactor exchange, in response to the estimated contactor wear.
