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 the first 3 items, a circuit board attached to the battery can monitor the battery voltage and the current going out. These are often referred to simply as protection circuits. They are very common on standard batteries but you must check the datasheet or product image to verify that a protection circuit is attached
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.
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.
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 Batteries are described in BU-304a: Safety Concerns with Li-ion.
