Resumen de The reduced basis method applied to transport equations of a lithium-ion battery

Stefan Volkwein, Andrea Wesche

• urpose – In this paper, the authors aim to show how to apply the reduced basis method to the transport equations of a lithium-ion battery.

  Design/methodology/approach – The authors consider a coupled system of nonlinear parameterized partial differential equations (P2DEs), which models the concentrations and the potentials in lithium-ion batteries.

  Findings – The authors develop an efficient reduced basis approach for the fast and robust numerical solution of the P2DE system.

  Originality/value – By the reduced basis method, the authors get (reduced) solutions with a speed up factor of up to 18 in the presented examples in comparison to the original finite volume solutions.
