Learn MoreIf a lead acid battery heats up while charging, it can indicate a problem with the charging system or the battery itself. Overcharging can cause the battery to release hydrogen gas, which can be dangerous if it accumulates in an enclosed space.
Heat issues, in particular, the temperature increase in a lead-acid battery during its charging has been undoubtedly a concern ever since this technology became used in practice, in particular in the automobile industry.
Overcharging is one of the most common causes of overheating during charging. When the battery is overcharged, it can cause the resistance to increase, which leads to more heat being generated. This can cause irreversible damage to the battery, reducing its stored charge and shortening its lifespan.
Car batteries can get hot during charging due to the energy conversion process. However, excessive heat could indicate issues such as overcharging, a faulty alternator, or a weak battery that forces the alternator to work harder. It's crucial to monitor the battery's temperature during charging to prevent potential damage and ensure its longevity.
The aim of this study is to look at a less appreciated fact that during lead-acid battery discharge, an entropy-based phenomenon leads to a cooling effect, which may not be intuitively apparent as it is often negated by Joule heating due to large current flow.
Thus, during discharge, the generated Joule heat heats up the battery, while the electrochemical conversion of lead-based active materials with sulfuric acid to lead sulfate and water is accompanied by an endothermic reaction that cannot be neglected in terms of thermal management of the battery.
