Learn MoreHighlights Real-time aging diagnostic tools were developed for lead-acid batteries using cell voltage and pressure sensing. Different aging mechanisms dominated the capacity loss in different cells within a dead 12 V VRLA battery. Sulfation was the predominant aging mechanism in the weakest cell but water loss reduced the capacity of …
Learn MoreThe extent of heat generation depends of course on the internal resistance of the battery, but a high internal resistance limits high rate discharges, and in general, heat problems are not observed during the discharge of lead-acid batteries due to the limited amount of energy that is available (cf. e.g. Section 4.5.1 in [4]).
Learn MoreThe consequences of high heat impact into the lead-acid battery may vary for different battery technologies: While grid corrosion is often a dominant factor for flooded lead-acid batteries, water loss may be an additional influence factor for valve-regulated lead-acid batteries. A model was set up that considers external and internal parameters ...
