Abstract

In the electric circuit of combustion cars, the electric energy is produced by the internal alternator, Therefore, in the case of use of the accessories during its stops or in the cranking phase, it is essential to put a battery to store the energy captured to provide power. We have proposed in this paper to study the modeling of a lead acid battery to highlight the physical phenomena that govern the operation of the storage system. This work is devoted to the modeling and simulation of two battery models namely the model CIEMAT and the simplified electric model PSpice under the MATLAB environment. A pulse discharge and charge test are performed on a commercial automotive lead acid battery in order to collect data to evaluate those models, results are presented and compared.
