6 FAQs about [Standards for lead-acid battery degradation]

What is the reliability analysis of a lead acid battery?

The reliability analysis of the lead acid battery is based on three stages. The first stage consists of constructing a causal tree that presents the various possible combinations of events that involves the batteries degradation during lead acid battery operation .

What are lead-acid battery standards?

Many organizations have established standards that address lead-acid battery safety, performance, testing, and maintenance. Standards are norms or requirements that establish a basis for the common understanding and judgment of materials, products, and processes.

Why does a lead-acid battery have a low service life?

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.

Are lead-acid batteries aging?

The lead–acid battery is an old system, and its aging processes have been thoroughly investigated. Reviews regarding aging mechanisms, and expected service life, are found in the monographs by Bode and Berndt , and elsewhere , . The present paper is an up-date, summarizing the present understanding.

Which criterion is reached when a battery is degraded?

A battery is degraded by the superposition of different degradation modes, thus the criterion of degradation is reached if the sum α1 + α2 + α3 + α4 equals 100%. The sum α1 + α2 + α3 + α4 indicates the aging of battery, it is considered degraded if the sum exceeds 100%. 5. Conclusion

What are the major aging processes affecting battery performance?

The major aging processes, leading to gradual loss of performance and eventually to the end of service life, are stratification of electrolyte, sulfating of the electrodes, corrosion of the electrodes and the loss of active mass adherence to the grid , , . Fig. 1. Causal tree of lead acid battery.
