The failure of a battery protection circuit can have far-reaching consequences, impacting both the performance of the battery and, more critically, the safety of the device or vehicle that relies on it. One of the primary functions of a battery protection circuit is to prevent overcharging and overdischarging.
Although battery protection boards are crucial, some problems can poorly impact their functions. Such problems are typically attributed to design flaws, component failures, and environmental factors. One of the most frequent causes of battery protection circuit failures is improper design.
The following mainly analyzes the lead-acid battery short circuit caused by excessive charging current, charging voltage of a single battery exceeds 2.4V, internal short-circuit or partial discharge, excessive temperature rise and valve control failure, and summarizes the treatment methods of lead acid battery short circuit as follows:
Humidity and dust: Exposure to moisture or dust can lead to corrosion or short circuits within the battery protection board, leading to malfunction. Vibration and mechanical shock: In applications like electric vehicles or industrial equipment, batteries may experience frequent vibrations or impacts.
If the protection circuit fails to detect the short circuit or overcurrent, it can lead to catastrophic failure. This not only damages the battery but can also harm the connected devices or even cause electrical fires. Thermal runaway is one of the most dangerous outcomes of a malfunctioning protection circuit.
Without regular maintenance, your UPS battery may experience heat-generating resistance at the terminals, or inside the jar improper loading, reduced protection and premature failure. With proper maintenance, the end of battery life can be accurately estimated and replacements scheduled without unexpected downtime or loss of backup power.
