UPS battery capacity calculation method: UPS battery usage capacity generally refers to the capacity contained in the rear end. Take 10kVA power size UPS as an example, output factor 0.9, then the full load power of the UPS is 9KW.
If the rear end load is 6KW, the UPS use efficiency is 6/9 = 66.7%. Battery capacity: Each battery safety amount AH = load total power W * Time (hours) H / 12V / battery series.
For example: 80K load, stand up to 2 hours, battery 32, 12V, 80000 * 2/12/32 = 416 * 1.2 = 500, 500 in 100AH batteries, such as: 3K load, To stand up to 1 hour, battery 8, 12V, 3000 * 1/12/8 = 31, 1 group with 24 or 38ah battery is good. Excessive large current discharge mode is unfavorable.
When the battery is configured for the UPS, the nominal capacity of the battery is not sufficient in the output current and battery power supply time required during the battery inverter, and is not based on the discharge rate and the selected battery specification according to the battery inverter. Output characteristics, increase the capacity of the UPS battery. Daily maintenance method for UPS batteries: 1.
Do not put the UPS battery in full sealing, you should choose the proper ventilation. 2. In order to obtain a longer life of the battery, theism should be supplemented in time to supplement the battery, and cannot be stored in the state of discharge.
3. The ambient temperature is allowed to be between -15 ° C -50 ° C during use, but longer life at temperatures 20 ° C -25 ° C. 4.
When the battery has an abnormal situation, it should be thoroughly examined, such as the bottom shell burst, damaged, leakage, etc. 5. The discharge current should not be too large, but also alert short circuit discharge.
After discharge, it should be charged in time. Do not allow UPS batteries to stand for a long time in discharge. .
