The protection circuit of a LiPo (Lithium Polymer) battery, often referred to as a Protection Circuit Module (PCM), is an essential component designed to safeguard the lipo battery from various potential risks during operation. This circuit is crucial for maintaining the safety and longevity of the lipo battery. Functions of the Protection Circuit:
Li-ion batteries are regularly exposed to several potentially damaging overtemperature conditions. Short circuits or deep discharges can increase temperatures in the battery …
The lithium battery protection board has four major functions: overcharge, overdischarge, overcurrent, and reverse connection protection. 1) Overcharge protection function: The overcharge protection function means that when a certain voltage is reached, it is forbidden to continue charging by the charger.
Protection circuits for Li-ion packs are mandatory. (See BU-304b: Making Lithium-ion Safe) More information on why batteries fail, what the user can do when a battery overheats and simple guidelines using Lithium-ion …

TEL: +886-2-2809-4742 1/11 DW01-P-DS-10_EN Rev. 1.0 ... z Load Detection Function during Overcharge Mode. z Two Detection Levels for Overcurrent Protection. ... Because the overcurrent protection voltage is preset, the threshold current for overcurrent detection …
Undervoltage Protection With Hysteresis The undervoltage condition for this design is when the battery voltage, VBATT, is 10-V. The voltage seen at the pin of the comparator must not exceed 5.7-V as specified in the Recommended Operating Condition table of the
3) Overcurrent protection function: The over-current protection function is to stop discharging the load when a large current is consumed. The purpose of this function is to protect the battery and the MOS tube to ensure the safety of the battery in the state. After the over-current detection, the battery will return to the normal state …
The reason why the lithium battery (rechargeable type) needs protection is determined by its own characteristics. Because the material of the lithium battery itself determines that it cannot be over-charged, over-discharged, over-current, short-circuited, and ultra-high temperature charge and discharge, so lithium battery or battery pack will …
