Heat Effects during the Operation of Lead-Acid Batteries
Thermal events in lead-acid batteries during their operation play an important role; they affect not only the reaction rate of ongoing electrochemical reactions, but also the rate of discharge and self-discharge, length of service life and, in critical cases, can even cause a fatal failure of the battery, known as "thermal runaway." This contribution discusses the …
Thermal Runaway Model of a Lead-Acid Battery (Part 1)
Thermal runaway only occurs when a battery is being overcharged. If you want to know how to drive a lead-acid battery into thermal runaway, take a look at the document "Induced Destructive Overcharge Test IEC Standard 952-1:1988." Its procedure works like a champ. The thermal overload model presented herein uses two equations: Input Power Equation
