A common type of batteries, UPS
The application of UPS power used in the battery has a total of three include: open type liquid lead-acid batteries, maintenance-free batteries, nickel-cadmium batteries battery life, influence factors, different types of batteries also have their respective advantages and disadvantages. The UPS manufacturers with the battery generally for maintenance-free batteries, battery mainly to avoid maintenance below introduces three characteristics of the battery:
1: open type liquid lead-acid battery
Such batteries by the structure can be divided into 8-10 years, 15-20 years two. As a result of this battery sulfuric acid electrolytic will produce a corrosive gas, the battery must be installed in the ventilation and away from the sophisticated electronic equipment room, and the battery room should lay fortify corrosion tile.
Due to evaporation causes, open battery required regular measurement of proportion, adding acid water. This battery can endure high temperature and high pressure and deep discharge. Battery room should be smoke-free and open type battery holder.
This battery can not transport, therefore it must be installed at the site after the initial charge normally takes 55-90 hours charging. Normal section of each voltage of 2V, initial charging voltage of 2.6-2.7v.
2: maintenance-free battery
Aka the VRLA batteries, in the use and maintenance of should abide by the following principles:
A: sealed battery allowable operating range of 15 degrees -50 degrees, but 5 degrees -35 degrees within the use of extended battery life. At 15 degrees below zero battery chemistry will be changed and not charging. In 20 degrees to 25 degrees within the scope of use will achieve maximum life span . Battery at low temperature operation will acquire long-lived but low capacity, during high temperature operation will obtain higher capacity but short life.
B: battery life and temperature relationships may refer to the following rules, more than 25 degrees Celsius, 8.3 degrees per high battery life will be reduced to half.
C: maintenance-free battery float charging voltage for the 2.3V/ section design. 12V battery for 13.8V. CSB recommends each section 2.25-2.3V. In the 120 series battery case, temperature above 25 degrees Celsius, the temperature of each degree rise in floating charge voltage should be down 3MV. The same temperature for each degree rise in order to avoid the battery charge voltage should be upregulated 3MV. Discharge termination voltage at full load ( <30 minutes ) cases for 1.67V per day. In the case of low discharge rate ( small current long time discharge ) will increase to 1.7V-1.8V per day, APCSYMMETRA can according to the load regulating charging voltage.
D: after discharge if the battery without recharging in 72 hours. Kraft will be attached to the plate insulating charging, and damage the battery.
E: battery during charging when the battery or, internally generated gas in anode plate electrolytic water, thereby maintaining the capacity of the battery without external water. But the battery pole plate corrosion will reduce the battery capacity.
F: battery life at an ambient temperature of 30-40 degrees of only 5-6 months. Long time storage battery every 6 months must be charged once. Batteries must be kept in dry and cool environment. In 20 degrees environment maintenance free battery self-discharge rate of 3-4% per month, and with the change of temperature.
G: maintenance-free batteries are equipped with safety valve, when the battery internal pressure is increased to a certain degree the safety valve can automatically discharge the excess gas in the internal pressure, the safety valve will automatically resume resume.
H: battery cycle life ( number of charge-discharge life) depends on the discharge rate, depth of discharge, and the restoration of the charging mode, one of the most important factor is the depth of discharge. In discharge rate and time, depth of discharge more shallow, battery cycle life is longer. Maintenance free battery in 25 of 100% cases deep discharge cycle life is about 200 times.
I: Battery arrived in life demonstrated capacity attenuation, internal short-circuit, casing deformation, plate corrosion, open circuit voltage reduction.
J:IEEE defines the end of battery life for the inadequate capacity nominal capacity AH 80%. Nominal capacity and the actual capacity of standby time nonlinear relation, reduce 20% corresponding backup time will reduce a lot. Some UPS manufacturers define battery end-of-life capacity to the nominal capacity of the 50-60%.
