Influence of a charging current with a sinusoidal perturbation on the performance of a lead-acid battery

Abstract

The effects of the battery current created by a charger operating in power factor correction (PFC) mode is investigated. In this case, the charging current contains a sinusoidal perturbation. This could deteriorate the performance of the charge compared to the classic charging technique, which uses a constant current. A dynamical model of the battery is proposed which facilitates an explaination of the contribution of the sinusoidal perturbation on the performances of a lead-acid battery. This theoretical facilitates the supposition that the DC component of the charging current is at the origin of the charge. This assumption is validated by the experimental results which show that the sinusoidal perturbation has no effect on the electrical performance of a lead-acid battery.
