Nonlinear model predictive control for lifetime extension of self-reconfigurable batteries
Résumé
Self-reconfigurable batteries (SRB) are advance battery systems where semiconductor switches allow cells to be connected or bypassed dynamically. The in-line configuration even allows the direct generation of AC current without any power converter while allowing a flexible cell usage. This paper introduces a new method of SRB control with nonlinear Model Predictive Control (nMPC) with the aim to reduce battery ageing. A full battery cell model is used to perform the minimization of the SRB capacity losses. Simulation results on WLTP profile validate the proposed method with a capacity loss reduction of 12.4%.
