Yes, ternary lithium batteries will also be balanced when not fully charged. Balance means that during the charging or discharging process, the state of charge between individual battery cells remains consistent to ensure battery performance and lifespan. Ternary lithium batteries are usually made up of several cells and there may be a slight charge imbalance between these cells. In order to prevent the charge difference between battery cells from being too large, causing some cells to be too high or too low, affecting the life and safety of the battery, the battery management system Battery will perform balancing operation during the charging process to reduce the charge from voltage to higher voltage cells are transferred to lower voltage cells to maintain char balancege between the battery cells. Therefore, even if the ternary lithium battery is not fully charged, the balancing operation will be performed.
How to identify whether the lithium battery protection board has an equalizer
Lithium iron phosphate has good charging and balancing. Charge balancing of lithium iron phosphate batteries is more commonly used and more effective than discharge balancing. The reason is that charge balancing can achieve charge balance between individual battery cells during charging and make full use of charging time for more efficient distribution. charging in each battery cell, improving overall performance and battery life. Balancing discharge requires balancing the battery during the discharge process, which will reduce the efficiency of battery discharge.erie and will thus affect the overall performance of the battery. Lithium iron phosphate batteries have the advantages of large capacity, long life and high safety. They are currently one of the types of batteries commonly used in electric vehicles and other fields.
Why do lithium batteries need to be balanced? what is the reason?
The way to know whether the lithium battery protection board has an equalizer is to observe the number of interfaces on the protection board and observe the circuit components on the protection card.
1. Observe the number of interfaces on the protection board: The protection board with an equalizer will have several sets of interfaces to connect the positive and negative poles of each battery in the battery to achieve balance between the batteries. . Dump. The unrivaled protection cardeur only has a set of input and output interfaces to connect the battery and external power supply.
2. Observe the circuit components on the protection board: There will be several circuit components on the protection board with an equalizer, such as capacitors, resistors, field effect transistors, etc., which are used to obtain Balanced charge between batteries. The protection board without equalizer only has basic protection components, such as fuses, fuses, etc.
The prerequisite for balancing is coupling. The battery must be coupled so that the internal resistance and charge-discharge curve of each battery are basically consistent.
If they are inconsistent, one battery will be discharged first, and other batteries will charge it, resulting in a reduction in overall discharge efficiency. This battery will also be indamaged first, causing the entire battery to fail.
