distribution system . In the UPS field , the proportion of lead-acid batteries is high . However , lead-acid batteries have a short service life , poor reliability , low energy density and a large footprint . Therefore , the reliability , availability and flexibility of the UPS solution are greatly reduced . Compared with lead-acid batteries , lithium batteries have the following advantages :
• Less or even no battery replacement is required in the battery service life . This eliminates the risk of system breakdown caused by battery replacement .
• Under the same energy , the weight of a lithium battery is one-fourth that of a lead-acid battery
• The number of discharge times is more than five-times that of leadacid batteries
• In multiple major power outage scenarios , the charging speed is increased by more than four times
The UPS solution that uses lithium batteries is becoming a new choice for customers due to the advantages of lithium batteries , the decrease in lithium battery prices and the increasing cost of lead-acid batteries .
Huawei launches the FusionPower integrated power supply and distribution solution to lead the new trends of UPS
Huawei FusionPower series UPS integrates the input and output
HUAWEI SMARTLI BATTERIES BOAST HIGH RELIABILITY , LONG SERVICE LIFE , SMALL FOOTPRINT AND SIMPLE O & M .
cabinets and UPS . This simplifies power configuration and saves 40 % footprint and 60 % installation hours .
The full-module redundancy design that eliminates single point of failure , together with a warning for the failure of key components , proactive tripping when the system is abnormal , and iPower intelligent management , ensures reliable system running and simplifies O & M .
The iPower visualises monitoring of the full power supply and distribution link accurately locates faults and provides fault waveform recording and analysis functions .
It also checks the health status of vulnerable components such as fans , capacitors and batteries to identify potential faults in advance . The iPower intelligently detects the fan speed , predicts the capacitor lifespan , detects the internal resistance , temperature and voltage of batteries and analyses the state of capacity ( SOC ) and state of health ( SOH ) of batteries .
The iPower also provides the temperature monitoring function for nodes in the power distribution system to detect the copper bar temperature in real time and provides early warning to reduce fire risks .
In addition , Huawei FusionPower is used together with the Huawei SmartLi solution to increase data centre reliability . Compared with traditional lead-acid batteries , Huawei SmartLi batteries boast high reliability , long service life , small footprint and simple O & M .
Huawei SmartLi has the industry-unique active current equalisation technology and allows old and new battery cabinets to be used together . The circulating current of cabinets connected in parallel can be controlled to be less than 2 %, significantly reducing CAPEX .
The SmartLi uses the safest cells , that is , lithium iron phosphate ( LiFeP04 ) cells , modular design , and three-level battery management system ( from cell to battery cabinet and then to parallel battery cabinet system ) to ensure the reliability of the lithium battery . ◊
