Is the button cell battery cr1620 pack balancing protection board good? The balancing principle of button cell battery cr1620 protection board

　　Is the button cell battery cr1620 pack balancing protection board good? button cell battery cr1620 protection plate balancing principle. Many button cell battery cr1620 protection board manufacturers mention the balancing function when introducing their products. button cell battery cr1620 protection boards, which play an important role in the battery system, have gradually gained everyone's attention as an effective means of extending battery life. Among them, button cell battery cr1620 protection boards play a key role. The button cell battery cr1620 protection plate balancing system has also attracted widespread attention.

　　Is the button cell battery cr1620 pack balancing protection board good?

　　Currently, there are two methods of balancing multi-series button cell battery cr1620 systems on the market: traditional passive balancing and active balancing. There is some controversy over whether the button cell battery cr1620 pack protection board should have a balancing function. The following is some opinions from button cell battery cr1620 manufacturers.

　　1. Situations where balancing is necessary: When the button cell battery cr1620 pack is produced and stored for a long time, due to the different static power consumption of each channel of the protection board and the different self-discharge rate of each cell, the entire battery pack is formed in each string of batteries. The voltage of the button cell battery cr1620 pack is inconsistent, resulting in an obvious voltage difference, but under the condition of ensuring that the capacity is consistent, the equalizer has the function of equalizing the voltage of the button cell battery cr1620 pack, so that the battery pack capacity can be fully charged and fully discharged, so that the battery pack can maximize its performance. effect.

　　2. Situation when equalization does not work: Many people think that equalization works when the button cell battery cr1620 pack is used in the middle and late stages. In fact, when the battery pack is used in the middle and late stages, due to the different capacity losses of each cell, a capacity loss occurs. Poor, the battery cell capacity cannot be compensated by balancing the protection board. Therefore, we should understand that the button cell battery cr1620 protection board balances the voltage, but the capacity cannot be supplemented.

　　For button cell battery cr1620 packs with less than 13 strings, it is recommended not to have a balancing function, but the battery configuration must be strictly controlled to ensure that the cell capacity and internal resistance are as consistent as possible. Lithium batteries are afraid of storage, but not afraid of use! Lithium batteries should be stored individually rather than as a whole set. After assembly, the battery pack should be tested as soon as possible and handed over to consumers as soon as possible.

　　When charging a group of lithium batteries in series, each battery should be charged evenly, otherwise the performance and life of the entire battery group will be affected during use. Commonly used balancing charging technologies include constant shunt resistor balancing charging, on-off shunt resistor balancing charging, average battery voltage balancing charging, switched capacitor balancing charging, buck converter balancing charging, inductor balancing charging, etc.

　　Balancing principle of button cell battery cr1620 protection board

　　During the charging process of lithium batteries, each button cell battery cr1620 is equipped with a balancing circuit. During charging, the voltage of each battery is controlled through the balancing circuit of the button cell battery cr1620 protection board, so that each string of batteries remains in the same state, ensuring the safety of the button cell battery cr1620. Performance and longevity.

　　The single-cell button cell battery cr1620 protection chip of the button cell battery cr1620 protection board balancing principle control circuit can be selected according to the voltage level, protection delay time, etc. of the single-cell button cell battery cr1620 to be protected. The shunt discharge branch resistance can be implemented using a power resistor or a resistor network.

　　The button cell battery cr1620 protection board balancing principle protection chip subsystem model mainly uses logic operation modules, symbolic function modules, one-dimensional table lookup modules, integration modules, delay modules, switch modules, mathematical operation modules, etc. to simulate the timing and logic of protection actions. Since there are certain differences between the simulation environment and the real circuit, filtering and strong and weak electrical isolation are not required during simulation, and redundant modules can easily lead to lengthy simulation time.

　　According to the needs of the application, the balancing principle of button cell battery cr1620 protection board can realize protection and equal charging of power button cell battery cr1620 packs of any structure and voltage level after changing the protection chip model and series number, and the power level of switching devices and energy consumption components in the circuit. .

　　Summary: The button cell battery cr1620 protection board has the function of protecting the battery and preventing the battery from overcharging. Balance has the function of equalizing the voltage of the button cell battery cr1620 pack, so that the battery pack capacity can be fully charged and discharged, so that the battery pack can exert its maximum effect.
