What is the capacity division function of lithium iron phosphate battery?

When Pacific Automotive Network divides the battery capacity, it obtains the data of each detection point through computer management, thereby analyzing the size and internal resistance of the battery capacity and other data to determine the quality level of the battery. This process is the division of abilities. Each battery capacity channel can be started and stopped at one point, and the response speed is fast. Each channel has an independent constant current source and constant voltage source, real-time sampling of current and voltage, and continuous switching from constant current to constant voltage without disturbance. Can be used for life testing.

A simple understanding is sorting by capacity and monitoring and evaluating performance. When the capacity of the lithium battery is divided, the data of each detection point isnt obtained through computer management, and the data such as the size and internal resistance of the battery capacity are analyzed to determine the quality level of the lithium battery. This process is capacity division. . After the lithium battery is divided into volumes for the first time, it must remain idle for a certain period of time, generally at least 15 days. During this period, some inherent quality issues will appear.

After a batch of lithium batteries is made, even if the size is the same, the capacity of the battery will be different. Therefore, the device must be fully charged according to specifications and then discharged (fully discharged) according to the specified current. The time required to discharge the battery multiplied by the discharge current corresponds to the capacity of the battery. Lithium batteries are only qualified if the tested capacity reaches or exceedshas designed capacity. Batteries with a capacity lower than the designed capacity cannot be considered qualified. This process of selecting qualified batteries through capacity testing is called capacity classification.

What is the role of lithium battery capacity classification? The lithium battery cells produced cannot be sold immediately. They must be stored in the warehouse for at least 15 days. During this period, some inherent disadvantages will appear. , such as self-discharge. If the cells are too large, etc., and have reached the shelf life in the warehouse, after receiving the order, they will be removed and tested again and the capacity will be divided again, i.e. that is, they will be charged and discharged again, and the cells whose capacity cannot reach the level or have quality problems will then be returned to thecommercial service with approximately 50% of the power maintained, and finally to commercial service. Mobile phone battery pack assembly factory.

The cells that will be used for the assembly of the lithium battery are again divided into mechanical parts. Through this process, you can still select some cells that do not meet the requirements and return them to the cell factory. After passing the mechanical detection test of the lithium battery, it can be seen that the battery core has been charged and discharged and is charged. So when you receive the battery, it has two electrical cells, which is normal.

Each channel of the battery capacity can be started and stopped at one point, and the response speed is fast. Each channel has independent constant current source and constant voltage source, real-time sampling of current and voltageand continuous switching from constant current to constant voltage without disturbance. Can be used for life testing.

Lithium battery classification and grouping involves selecting and combining monomers with the same internal resistance and capacity. When combined, only those with very similar performance can form a lithium battery. For example, in order to meet the energy needs of electric vehicles, power batteries often require tens or even thousands of batteries. Affected by the complexity of the system, the behavior of the battery has its own peculiarity, and it is not simple. Single battery function. The performance of lithium battery can be obtained by addition and subtraction.
