Model order reduction via proper orthogonal decomposition for a lithium-ion cell

– The simulation of lithium-ion batteries is a challenging research topic. Since there are many electrochemical processes involved in charging and discharging, models which aim to include these processes are in general complex and therefore slow. This paper seeks to address these issues.

– For many tasks, e.g. in optimization, a repeated solution of a model is necessary.

– In this paper, a speed up in simulations, with acceptable error in results, is obtained by combining proper orthogonal decomposition with empirical interpolation method.

– The authors report a speed up factor between 10 and 15.
