What factors affect the capacity of UPS batteries?

1. The influence of the plate area. Under the condition that the volume of the UPS battery case is the same, the thin plate is selected, and the number of plates is added, that is, the area of u200bu200bthe plate is increased, which improves the capacity and specific energy of the battery and improves The high current and low temperature discharge function of the battery, but the disadvantage is that the floating charge life of the UPS battery will be slightly reduced. 2. The influence of the height of the electrode plate In the direction of the height of the electrode plate, the active material utilization rate is not uniformly distributed, especially when the electrode plate is high, the utilization rate of the lower half of the electrode plate is poor. At the initial stage of discharge, the current density on the upper part of the electrode plate is about 2 to 2.5 times that of the lower part. The current density gradually decreases as the discharge progresses, but the current density on the upper part is always higher than that of the lower part. Therefore, the electrode plate should not be designed with small width and high height. 3. The influence of the thickness of the plate has been commented in the previous section on the influence of the discharge rate on the capacity of the UPS battery. Because of the restriction of the dispersion of H2SO4, the depth of the active material effect is limited. Therefore, with the increase of the plate thickness, the utilization rate of the active material will be reduced. reduce. This point becomes more prominent during high current discharge. However, because of the longer floating charge and cycle life of this UPS battery, it is widely used in communication backup power supplies. 4. Concentration of electrolyte In lead-acid batteries, the electrolyte is also a reverberant. Under a certain volume, the concentration of added electrolyte is equal to the addition of reactive substances. Therefore, within the range of electrolyte concentration used in practice, follow the electrolyte concentration. Add, UPS battery capacity is also added, especially when the battery capacity is restricted by the positive plate at high rate discharge. Therefore, the selection of the appropriate electrolyte concentration must be combined with the practical application field.
