The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

The results demonstrate that the proposed approach achieves accurate parameter estimation with rapid iterative convergence, and it shows strong potential for application to other battery models.

C2weakest assumption

That the local Gaussian approximations in ensemble Kalman inversion remain adequate for the strongly nonlinear and multi-physics battery dynamics, and that the collected data sufficiently excites all relevant parameters without unmodeled disturbances.

C3one line summary

Ensemble Kalman inversion achieves accurate parameter estimation with rapid convergence for nonlinear electro-thermal battery models in both simulation and experiments.
