Briefly discuss the application and selection skills of lithium battery protection chip

Lithium battery protection chip is a device that integrates the functions of battery protection and management. It is mainly used for the safety protection and power management of lithium ion battery and polymer lithium ion battery. The following isLithium battery protection chipApplication and selection skills of:

1. Application:

Lithium battery protection chip is mainly used for the protection of overcharge, overdischarge, short circuit, overcurrent and other abnormal situations of battery pack, which generally includes the following functions:

(1) Voltage protection: When the battery voltage exceeds or is lower than a certain value, the output circuit can be disconnected to play the role of voltage protection.

(2Overcurrent protection: When the charging and discharging current exceeds the value set by the chip, the chip will disconnect the output circuit to protect the battery from damage.

(3Short-circuit protection: When the output is short-circuited, the chip can immediately disconnect the output circuit to protect the safety of the battery and the circuit.

(4) Temperature protection: When the battery temperature exceeds a certain value, the chip will disconnect the output circuit to protect the battery and circuit safety.

2. Selection skills:

(1The voltage and current range of the protection chip should match the battery parameters to ensure that the chip can provide adequate protection.

(2The size and appearance of the chip must meet the requirements of the application environment and match the design of the battery pack.

(3Considering the performance and price of the chip, it is not appropriate to blindly pursue higher prices in order to pursue higher protection capabilities.

To sum up, the application and selection skills of lithium battery protection chips are very important for the safety protection and power management of lithium-ion batteries and polymer lithium-ion batteries.
