How to solve the problem of excessive internal resistance of Panasonic battery?
Panasonic batteries will appear in the use of excessive internal resistance phenomenon, then do you know how Panasonic batteries appear excessive internal resistance phenomenon should be solved?
When the internal resistance of Panasonic batteries exceeds 80 m, the solution requires balanced charging or activation of Panasonic batteries. The increase of internal resistance of batteries will inevitably accompany the decrease of actual output energy, which shows that the capacity of batteries decreases. When the internal resistance of 100AH batteries reaches 80M, the actual capacity of batteries is only about 50AH or less. In addition, there are other factors causing the reduction of the capacity of batteries, such as electrolyte loss.
I. Charging and Discharging Problems
In exactly the same environment, a small amount of Panasonic battery power is used, which has a very small impact on the resistance of the battery. If a large number of abnormal charges and discharges occur, the resistance will change, usually discharging at a low rate of 20%, and less than 3% of the internal resistance will be observed.
II. Temperature Effect
The resistance of Panasonic batteries is affected by external environment. Once the temperature is abnormal, too high or too low, the effect of high temperature at 102 degrees Fahrenheit on the internal resistance of batteries is very small (less than 2%). Low temperature has some effect on internal resistance, but the effect of temperature on internal resistance of temperature battery is very weak when the temperature of electrolyte is not lower than 65 degrees Fahrenheit.
III. THE INFLUENCE OF SULFIDATION PHENOMENA
Panasonic batteries have been idle for a long time, and the negative electrodes have been in a state of incomplete charging for a long time, resulting in irreversible damage to active materials, which is lead sulfide, affecting resistance.
IV. Drying up of Electrolyte
Electrolyte is essential for batteries. When using Panasonic batteries, we should pay attention to the use of temperature, the number of charges and discharges, vulcanization and drying up of electrolyte. Drying up of electrolyte will lead to resistance problems.
