UPS battery charging method, UPS battery charging error concept. In today's most reserve power DC system, the storage of energy in UPS, etc. is implemented with battery packs.
So as the charging method of the battery pack for uninterrupted power supply, it is very important. There are many ways to charge the UPS battery, and the scientific and reasonable charging method will greatly improve the maintenance effect of the battery. UPS battery charging method UPS battery first charge is called initial charging, the initial charging has a great impact on the service life and charge capacity of the battery.
If the charging is insufficient, the battery charge capacity is not high, the service life is short, and the number of charging is also increased; if the charge is over, the UPS battery is electrically resistant, but it will damage the battery itself, shorten its service life, so new UPS battery should be careful to make initial charging. About normal UPS batteries must be charged according to charging specifications before use. Regarding the dry charge battery, it is necessary to use in the specified instructions for use in the specified density of the specified density.
However, if the storage period is more than two years, due to some oxidation on the plate, in order to improve its charge capacity, supplement charging should be supplemented before use, charge 5 hours to 8 hours, then charge again. In the use of medium charge, the amount of discharge is unbalanced. If the discharge is greater than charging, the battery polar plate will slowly vulcanize.
This chronic vulcanization will cause the battery charge capacity to decrease until the start is weak, which greatly shortens the service life of the UPS battery. The active substance on the battery polar plate is reduced in time, reducing the polar plate vulcanization, improves the battery charge capacity, extending its service life, and the battery should be replenished periodically. After the new UPS battery is put into use, charging and discharging must be performed regularly.
UPS battery charging and discharge conditions will directly affect the electrical energy and service life of the battery. Charge and discharge control for the UPS battery should be based on the physical chemical characteristics of the battery itself, to extend the battery with the maximum limit of the battery, extend its service life. The user is still based on its own application needs, and smart charging is the most widely used in the current application.
It is also a better way. Common UPS Battery Charge Method 1, pulse charge is a simple and economical method, and the low-voltage AC rectification of the transformer secondary output is charged to the battery. This method is relatively large, the charging speed is fast, the disadvantage is that the charging current fluctuates when the grid voltage fluctuates.
It is prone to occur due to large charging current, high battery temperature, large loss of electrolyte, resulting in battery damage, so this method is maintenance-free sealing lead-acid battery rarely. 2, with constant current charging In order to prevent the temperature rise of the UPS battery and the loss of the electrolyte is too large, the charging current is adjusted, the time to charge is longer, on the other hand, the charging time is too long, will happen Charge, in order to prevent the battery from being damaged due to overcharge, it is necessary to have a charge or press circuit. 3, constant voltage charging theory and practice, prove, when the charging voltage is lower than the charging voltage limit (for 12V battery, this value is) is safe, even if the charging time is very long, it is not dangerous, if you want UPS battery can also work in a floating state.
UPS Battery Charge Error Concept Many people do not pay too much to pay too much to pay for the charging use of the UPS battery, think that it is not reasonable to use the UPS battery life Decreased, but pushed responsibility to UPS battery manufacturers. 1. The polarity of charging is poor due to the different lead-acid battery positive and negative plate materials, in addition to the active substance, the negative electrode plate also adds material such as barium sulfate, humic acid, carbon black and rosin to prevent the negative electrode plate shrinkage and Oxidation.
Further, the number of negative electrode plates of each single lead-acid battery is always more than the number of positive electrode plates, and the negative electrode plate is slightly thinner than the positive electrode plate. When the primary charge or supplement charge of a lead-acid battery is performed, if it is not paying attention to the polarity, the lead-acid battery can be pressed, and therefore, it is necessary to pay attention to polarity when charging, and it is unpolated. 2.
UPS battery Excess charging UPS battery initial charge should not be overcharged, but after normal use, it is often charged, even if the charging current is not large, the electrolyte is "boiling", in addition to the fine particles of the active material surface, also It will make the grid over oxidation, resulting in loose peeling of active substances and grids. Summary: The above is a little insight to make the UPS battery charging method. The new method will inevitably have a lot of not thoughtful places, but technology always makes progress and perfect, I hope that all peers will give more valuable advice to make Battery management technology is more perfect.
