Capacity degradation is the main failure mode of lead–acid batteries. Therefore, it is equivalent to predict the battery life and the change in battery residual capacity in the cycle. The definition of SOH is shown in Equation (1): where Ct is the actual capacity, C0 is nominal capacity.
On the other hand, at very high acid concentrations, service life also decreases, in particular due to higher rates of self-discharge, due to gas evolution, and increased danger of sulfation of the active material. 1. Introduction The lead–acid battery is an old system, and its aging processes have been thoroughly investigated.
The lead-acid battery system is designed to perform optimally at ambient temperature (25°C) in terms of capacity and cyclability. However, varying climate zones enforce harsher conditions on automotive lead-acid batteries. Hence, they aged faster and showed lower performance when operated at extremity of the optimum ambient conditions.
In this role the lead acid battery provides short bursts of high current and should ideally be discharged to a maximum of 20% depth of discharge and operate at ~20°C, to ensure a good cycle life, about 1500 cycles orthree to five years of operation .
Availability, safety and reliability issues—low specific energy, self-discharge and aging—continue to plague the lead-acid battery industry, 1 – 6 which lacks a consistent and effective approach to monitor and predict performance and aging across all battery types and configurations.
SLA batteries were observed to degrade faster at higher temperatures (25°C and 40°C). However, the degradation is minimal at lower temperatures (0 and −10°C) due to less active material and slower kinetics. The impedance value, x axis intercept of the Nyquist plot, was observed to increase with cycling at all temperatures.
Characteristics of Lead Acid Batteries
The following graph shows the evolution of battery function as a number of cycles and depth of discharge for a shallow-cycle lead acid battery. A deep-cycle lead acid battery should be able to maintain a cycle life of more than 1,000 even at DOD over 50%.
