Simulation of lead-acid battery using model order reduction
In this study, a reduced order model (ROM) based on proper orthogonal decomposition (POD) method has been applied to the coupled one-dimensional electrochemical transport equations in order to efficiently simulate lead-acid batteries, numerically. The governing equations, including conservation of charge in solid and liquid phases and conservation of species are solved simultaneously. The POD-based method for a lead-acid cell is used to simulate a discharge process to show the capability of the present method. The obtained results show that not only the POD-based ROM of lead-acid battery significantly decreases the computational time but also there is an excellent agreement with the results of previous computational fluid dynamics (CFD) models.
