A battery ageing model used in standalone PV systems
Abstract
The author present a new model for the aging of a Lead-Acid battery which is based on the initial model of the Shepherd.The proposed model allows to predict temporal variations of the Shepherd coefficients and to control the deterioration of battery parameters and performances.The model validation has been realised by the recursive least square algorithm by using long term measurements under several socialisation.This study will improve the storage section of stand alone photovoltaic systems and reduce the overloads and deep discharges.
