Free QuoteThe Protection Circuit Module (PCM) is designed to protect lithium batteries during charging and discharging. It consists of electronic hardware components that monitor voltage levels, detect overcharge and undervoltage conditions,
Free QuoteA common way to mitigate the risk of this type of destructive event is to place MOSFETs in the charge and discharge paths that can sever the electrical connection between the battery and

Free QuoteThis degrades the recharge capability of the battery as well as its efficiency. Therefore, there should be a protection circuit which can monitor the level of charging of the battery by detecting the terminal voltage and protect the battery from over-discharging by cutting off the battery connection with the electronics device.
Battery protection circuits / IC solutions and reference designs that allow easy design-in and ensure safe charging and discharging - prevent damage and failures.
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.
Some protections are required during the charging process, while others make sense only during the discharge process. Thus, some protections are implemented as part of the charger, while others are implemented as part of the battery management system that oversees the charging and discharging process of the battery.
The battery protection circuit disconnects the battery from the load when a critical condition is observed, such as short circuit, undercharge, overcharge or overheating. Additionally, the battery protection circuit manages current rushing into and out of the battery, such as during pre-charge or hotswap turn on.
Use special lithium battery protection chip, when the battery voltage reaches the upper limit or lower limit, the control switch device MOS tube cut off the charging circuit or discharging circuit, to achieve the purpose of protecting the battery pack. Characteristics: 1. Only over-charge and over-discharge protection can be realized.
