In another study, Svoboda et al. classified lead–acid batteries into categories for lifetime considerations of the components of renewable systems and for analysing the properties and performance of these systems.
Lifetime estimation of lead–acid batteries in stand-alone photovoltaic (PV) systems is a complex task because it depends on the operating conditions of the batteries. In many research simulations and optimisations, the estimation of battery lifetime is error-prone, thus producing values that differ substantially from the real ones.
In these cases, for lead-acid batteries, the equivalent full cycles model or the rainflow cycle counting model overestimated the battery lifetime, being necessary to use Schiffer et al.’s [ 30] model, obtaining in the case studied a lifetime of roughly 12 years for the Pyrenees and 5 years for Tindouf.
Li-ion batteries ( [ 34, 35, 36 ]) have a higher cycle life, energy density, and energy efficiency, and lower maintenance compared to lead-acid batteries. The LiFePO 4 (LFP) type is the most used in off-grid systems. Li-ion batteries’ most significant aging external factors are temperature, charge and discharge rates, and DOD [ 37 ].
The battery charge controller significantly affects the lifetime of batteries. The results show the weighted Ah-throughput model provides more accurate values. Lifetime estimation of lead–acid batteries in stand-alone photovoltaic (PV) systems is a complex task because it depends on the operating conditions of the batteries.
Electrochemical battery models (Doyle, Fuller, and Newman, 1993; Haran, Popov, and White, 1998) are based on partial differential equations accounting for the dynamics of particles inside the battery. Albeit highly accurate, these models are quite complex and require knowledge of a large number of parameters which are difficult to obtain.
