Analyze the four functions of multi-series lithium battery protection chip in the circuit

Multi-string lithium battery protection chipIt is an electronic protection component that monitors battery voltage, current and temperature during the charging and discharging of lithium batteries to ensure the safe operation of the battery and extend the service life of the battery. Compared with the traditional single series lithium battery protection chip, the multi-series lithium battery protection chip can monitor and protect multiple series lithium batteries at the same time.

The main functions of the multi-series lithium battery protection chip include the following aspects:

1. Battery voltage monitoring and protection. The multi-string lithium battery protection chip monitors the voltage changes of each series battery to ensure that the voltage of each battery is within the safe range, and cuts the circuit when the battery is over or under voltage to prevent battery damage or cause accidents such as fire.

2. Charge and discharge control. By preventing the charge and discharge flow of the battery during overcharge or overdischarge, the battery is protected from the influence of overcharge or discharge, and the battery charge and discharge are balanced to extend the service life of the battery.

3. Temperature monitoring and protection. The multi-string lithium battery protection chip can also monitor the battery temperature to avoid overheating or overheating of the battery, thereby protecting the battery and equipment from damage.

4. Short circuit protection. In the event of a short circuit in the battery, the multi-string lithium battery protection chip will immediately cut off the circuit to prevent excessive discharge of the battery or accidents such as fire.
