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 ...

What are the factors that affect the efficiency of the battery spot welding machine?
Dec 24 , 2021
●Welding current Since the heat generated by the resistance is proportional to the square of the current passed, the welding current is the most important factor in generating heat. The importance of welding current does not simply refer to the size of the welding current, the current density is also very important. ※Nugget: refers to the metal part that solidifies after the melting of the ...
