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.
Going beyond the operating limits can be crucial for a battery and may lead to its degradation and untimely death. More importantly, a battery’s failure can be dangerous to its user. For example, lithium-based batteries are notorious for their inflammability and have a high risk of fires and explosions.
Battery protection circuits have become quite popular due to their usage in various electronics such as cell phones, laptops, electric automobiles, etc. Nevertheless, battery protection circuits are not beyond being susceptible to failure like any other circuit.
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.
You can control the battery’s current and voltage in two principals ways: carry out overcurrent and overvoltage protection during charging and avoid undervoltage as you discharge the battery. The main point: Every battery type has recommended current and voltage limits for both charging and discharging.
