Abstract

The present disclosure relates to a computer-implemented method of determining one or more operating parameters of an electrical device comprising by means of a multi-parameter sensing film (200, 300). It also relates to a battery module and a battery system comprising the sensing film. The sensing film comprises:- a substrate (201,301),- one or more sensing elements (210, 310a-310d) arranged on said substrate, wherein said one or more sensing elements are formed by at least one responsive material which is configured to exhibit changes in electrical resistance in response to changes in said operating parameters,- a plurality of monitoring circuits (204a-204d, 304a-304d) arranged at predefined monitoring positions (202a-204d, 302a-302d) that are spaced apart from each other over said substrate, said monitoring circuits being configured to monitor the electrical resistance of said at least one responsive material at monitoring positions,the method comprising:- detecting (S1) electrical resistances of said at least one responsive material at monitoring positions, and- determining (S2) the one or more operating parameters at said monitoring positions by using information of the detected electrical resistances.
