The circuit monitors the voltage of a Li-Ion battery and disconnects the load to protect the battery from deep discharge when the battery voltage drops below the lockout
Importance Of Battery Protection. In BMS, battery protection plays a key role. Particularly, lithium-ion variants, which are a type of high-energy storage devices, and batteries can work within specific physical and electrochemical limitations. Reduced performance, decreased lifecycle, and potentially harmful scenarios like thermal runaway
DIY lithium battery builders will also measure the voltage of used (and new) battery cells — such as LFP cells and 18650 lithium batteries — to see which are good and which are duds. Measuring voltage is also a good way to check if a lithium battery (or any battery) is dead or not. 2. Use a Battery Monitor. Pros: Most accurate, convenient

Lithium batteries have the advantage of high energy density. However, they require careful handling. This article discusses important safety and protection considerations when using a lithium battery, introduces some common battery protection ICs, and briefly outlines selection of important components in battery protection circuits. Overcharge
Another internal protection is PTC. PTC is a thermal fuse which used to prevent the thermal runaways. PTC will shutdown the batteries if the battery temperature is overheated , . circuit and keep the cell in open state. Table 3 shows the comparison between LIB fault, types of abuse and how the fault will be managed.
A Lithium-ion battery protection circuit is specifically designed to protect lithium-ion cells. It typically includes a combination of electronic components such as transistors, diodes, and resistors that work together to control the current flow.
For this reason, the cells and charge/discharge circuits of lithium-ion batteries currently on the market are always equipped with a control function called “primary protection” to prevent problems that could lead to accidents, such as overcurrent or overcharge. However, even the very best electronic circuits can fail in rare cases.
