How to test the technical status of the UPS power battery? The UPS power storage battery test can generally be done with the battery tester. If the user's personal needs to detect the quality of the battery is not completed, a large company in general processing UPS batteries will have a battery tester, but some small batteries Processing companies choose third-party testing organization when making battery testing. How to test the technical status of the UPS power battery? 1, discharge method: That is, discharge the UPS power storage battery with the discharge detector, which can be more accurate measurement of the capacity and quality of the battery.
But the detection time is longer. 2, the conductance detection method: that is, the method of detecting the capacity of the UPS power supply battery is used to determine the quality of the battery and the capacity of the battery. Generally, bad battery electrical conductivity is small.
However, due to the relationship between the battery conductance and the battery capacity is not very tight, it detects that the battery capacity error is large. Battery test method 1: Measuring the monomer voltage method Put the range of the multimeter in the DC100V file, put the two ends of the table stick in the positive and negative poles of the monomer, the same color in the same color is the same monomer. Positive and negative.
If the battery is not in use, the measured voltage is the open circuit voltage of the battery. If the battery is used, the measured voltage is the operating voltage. The work voltage is related to the measurement, the larger the working current, the smaller the operating voltage.
2: Supreme reading uses thermometer to measure the electrolyte temperature. The suction tube densitometer is vertically inserted into the electrolyte, extruded the rubber pipe with finger, and the electrolyte is sucking into the glass tube, and the density is floating. Readout density reading.
Testing the quality of the UPS power battery A. Appearance test is difficult to distinguish between the Quality of the UPS power battery due to the use of specialized tools, so it can only be impressed from the appearance before purchasing. The purchaser should see whether the outer packaging of the battery is unsatisfactory.
Is the battery housing and connection terminals are not cleaned, the seal is not good, the terminal welding is fixed, there is no leakage, deformation, crack, corrosion, etc. Can reflect the quality of the battery from one side. B.
The capacity of the charge and discharge test battery is not to reach the nominal value. It can be detected by charge and discharge experiment. After more than 8 hours, the newly purchased UPS battery is continuously charged, discharge experiments with a certain resistance of the resistance, discharge When the battery is measured at time, the end voltage is measured, according to the ratio map of the end voltage decreases over time, the battery is slower battery.
In order to further check the fault nature and extent of the UPS power storage battery in order to further check the fault nature and extent of the UPS power storage battery, it can be inspected in combination with the battery charging process, according to the different performance of the battery in the charging test, Judging the internal failure of the battery and its original. Normal state. When charging in advance, the battery voltage and electrolyte proportion is rising according to certain regulations, and the electrolyte temperature is not high.
This statement of the battery is normal, but it is too much discharge, and it should be charged. 2. Vulcanization state.
Internal vulcanized Guangdong soup shallow battery When charging, the initial single voltage can rise to about 2.8V, the electrolyte temperature is also high, with the sustainable charge, after a few hours, the single voltage dropped to 2.2V, afterwards Slowly rising and good battery charging law.
Internal serious vulcanized battery, the voltage of single-single battery will be higher than 2.8V, the specific gravity of the electrolyte does not rise, at the beginning of charging, the battery will have spurious phenomenon. 3.
Active substance falls off. When the active material is severely detached, the electrolyte is turbid, the battery capacity is reduced, and the charging time is shortened, and the phenomenon of the electrolyte boiling and the like will also appear in advance. 4.
Discharge self-discharge. Battery with self-discharging, long charging time, slow in electrolyte specific gravity and end voltage. If there is a serious short circuit inside the battery, no matter how long the charging time is long, the electrolyte specific gravity does not rise, and there is no bubble in the battery, and the electrolyte is like a pool.
Regarding the manager of the UPS power battery, everyone is very clear that the battery is daily maintenance and testing only on related experience and tips, the times are progressing, there is a large amount of battery, and there is a dedicated "battery internal resistance" "Detector" to test, in order to find backward batteries, detect the internal resistance and voltage of the battery, initially estimate the capacity of the battery, to process the battery capacity is difficult to detect, and after checking the backward battery, you can do it. Effective master of the daily state of the UPS battery. .
