crucial when using lithium-ion batteries because if the battery is discharged below its rated value, the battery will become damaged and potentially pose a safety hazard. In addition to undervoltage protection, it is important to ensure that the battery is discharging a safe current value. Combining undervoltage protection and overcurrent
However, the widespread use of batteries has also brought about current problems, where the presence of overcurrents can lead to catastrophic accidents such as equipment failures, fires, and even explosions. Therefore, overcurrent protection has become a key element in ensuring the safety of battery applications.
Here is how the battery protection board works for overcurrent protection: 1. Current monitoring: The battery protection board is connected to the positive and negative terminals of the battery pack and monitors the flow of current in real-time by means of a current sensor or current measurement circuit.
Thus, overcharge protection is vital for maintaining battery safety. PCMs protect against overcurrent and short circuits by monitoring the battery’s temperature and interrupting the circuit when necessary. Excessive current flow can cause the battery to overheat, posing a risk of fire.
Over-discharging can significantly reduce a battery’s capacity, lowering the voltage below safe levels (typically around 2.7V for lithium-ion cells). PCMs prevent over-discharge by cutting off the circuit when the voltage drops too low, preserving the battery’s health and prolonging its operational life.
