Method for determining a performance of a battery arrangement, Computer program, and Computer-Readable Medium

Patentradars sammanfattning

Scania CV AB discloses a method for more accurately predicting battery arrangement performance by obtaining and combining information on both the mechanical configuration (internal stress states, external forces, adjacent mechanical structures such as pads, busbars, housings, cooling plates) and the electrochemical configuration of the battery arrangement. The core novelty lies in coupling a mechanical model with an electrochemical model so that outputs of each serve as inputs to the other, capturing the complex interplay between mechanical and electrochemical phenomena that prior simulation approaches neglected. The method can be executed iteratively over a time interval to track performance degradation metrics such as SOH, capacity retention, internal resistance, and self-discharge rate. It is implemented as a computer program on a computer-readable medium, targeting automotive battery packs for electric vehicles.
