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.
A protection device must be sized properly so that the energy flowing from the batteries during the failure will not cause damage to the batteries or other components along the short circuit path. The protection must clear the fault in less than 100 milliseconds. The impedance of the line is mainly resistance and inductance.
The selected protection device must trip in case of a fault in less than 100 ms. In case the fault current provided by the battery does not allow for the finding of protection devices, such as a Circuit Breaker or fuse, that meets the derating criteria stated in point B, it is hence possible to increase the multiplier up to 0.7.
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.
Battery protection circuit is applied to protect the battery from overcharging, over-discharging, short circuits and other dangerous conditions to ensure the longest battery life for its use and to ensure battery safety.
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.
