Why use protective plates for lithium iron phosphate battery packs?
Jul 29 , 2021
The protection of lithium iron phosphate batteries is determined by its own characteristics. Because the material of the lithium-ion battery itself determines that it cannot be overcharged, over-discharged, over-current, short-circuited, and ultra-high temperature charging and discharging, the lithium-ion battery package will always appear with an exquisite protection board and a current fuse. The...

Introduce of lithium-ion battery diaphragm
Aug 12 , 2021
The diaphragm is an important part of the lithium ion battery, which is an important component that supports the lithium ion battery to complete the charge and discharge electrochemical process. It is located between the positive and negative electrodes of the battery, ensuring that the lithium ion is passed, and the electron transfer is hindered. The performance of the diaphragm determines the in...

How to calculate the charging and discharging time of lithium battery
Oct 21 , 2021
Generally, the capacity of lithium battery testing equipment is divided into constant current charging, constant voltage charging and constant current discharging in the process of testing lithium ion battery charging and discharging. 1. Constant current charging means that the current is always constant and the voltage slowly rises to the set value (the upper limit voltage of the ternary lithium ...

What are the preparations before starting the automatic spot welding machine?
Dec 10 , 2021
The electrode pressure of the battery pack automatic spot welding machine has a significant effect on the total resistance R between the two electrodes. As the electrode pressure increases, R decreases significantly, while the increase in welding current is not large, and it cannot affect the decrease in R. Heat production is reduced. Therefore, the strength of the solder joint ...
