What is the balancing principle of lithium battery protection board? -Lithium - Ion Battery Equipment
Lithium-ion battery protection board equalization principle Commonly used equalization charging technologies include constant shunt resistance equalization charging, on-off shunt resistance equalization charging, average battery voltage equalization charging, switched capacitor equalization charging, step-down converter equalization charging, inductance equalization charging, etc. When a group of lithium-ion batteries are charged in series, each battery should be charged in a balanced manner, otherwise the performance and life of the whole group of batteries will be affected during use. However, the existing single-cell lithium-ion battery protection chips do not contain the balanced charging control function, and the balanced charging control function of the multi-cell lithium-ion battery protection chip needs to be connected to an external CPU; it is realized through serial communication with the protection chip (such as I2C bus), This increases the complexity and design difficulty of the protection circuit, reduces the efficiency and reliability of the system, and increases power consumption.(Lithium - Ion Battery Equipment)
The equalization principle of the lithium-ion battery protection board is based on the requirements of the application. After changing the protection chip type and series number, the power level of the switching device and the power consumption element in the circuit, it can realize the protection and protection of the power lithium-ion battery pack with any structure and voltage level. Even charge.
As a battery with a relatively large power reserve, lithium-ion batteries are used in various computer rooms, communication base stations, data centers and other fields. The lithium-ion battery protection board has the function of protecting the battery and preventing the battery from being overcharged.
