Battery battery temperature reliability
Temperature has a large effect on the battery during natural aging. Detailed experimental data shows that every 5 degrees Celsius, battery life increases and the temperature will drop by 10%, so the UPS should be designed to maintain the battery temperature. All on-line, defensive lines run more than mixed or online interactive UPS heat storage / UPS, which is an important reason for the relatively long one of the back-end or online interactive UPS battery replacement cycle.
Battery charger, battery reliability design
Battery Charger A very important part of the UPS, battery charging conditions have a major impact on battery life. If the battery has a constant pressure or "floating" state of charge, the UPS can maximize battery life. In fact, the state of charge of life is not a simple state of storage, and the battery life is longer.
Battery battery voltage reliability
The battery is a single "universal cell", each to a 2 volt primary battery, the primary battery is connected in series to form a high voltage battery, a 12 volt battery and the original 6 to 24 volt battery composed of 12 main batteries. The UPS battery is charged in each of the defendant's original battery series. The original slightly different battery level will result in battery performance compared to any other battery with the original number of any high voltage battery, and the battery portion is prematurely aged. As long as the old man is an original, the battery performance of the series will degrade the battery performance is not good.
The capacity of the UPS is fixed, the minimum battery voltage that should be allowed to be designed, so that the life of the longer UPS power supply is a constant voltage, the voltage should be selected in series with a small number of primary cells, do not choose the original battery with a series low battery. The UPS manufacturer of the battery voltage is relatively high, because the capacity is fixed, the higher the voltage, the smaller the current, the smaller the wire and the smaller the power semiconductor can be, reducing the cost of the UPS. The voltage on the battery is usually UPS 1KVA 24 96V.
Battery reliability, battery ripple current
Ideally, to extend UPS battery life, always keep the battery "floating" or constant voltage charging. In this state, the power state, a fully charged battery charger will sink current, which is called "floating" or "self-discharging" current. Although battery manufacturers recommend a small number of undulating (many on-line) cells to design extra small currents, the ripple current is known. When the battery generates a constant ripple current, the inverter is as energy efficient as possible, and DC input AC must be generated from the inverter output. The charge and discharge cycles of this small battery, charge and discharge form a current frequency that is twice the UPS output frequency (50 or 60 Hz).
If the charger and inverter between the batteries are uninterruptible, the battery will have ripple current, which is a normal "double conversion" UPS. If the cut-off diode, relay, rectifier converter or battery is isolated from the inverter, the battery will not have ripple current. Of course, this is not always the "online" that Santak UPS has designed, so this UPS is a "mixed reserve/online" UPS.
