Lithium battery UPS power supply method and operating mode introduction. Lithium battery UPS power cells How to extend the cycle life? What are the UPS power lithium batteries? What are the main applications of UPS lithium batteries? These are some questions we deserve to think. UPS batteries have always been a very important part of power equipment, and lithium battery UPS has developed rapidly, volume and capacity density have very significant progress.
Today, you will introduce the use of lithium battery UPS power supply and operating mode. Correct use of lithium battery UPS power supply: First, use the ambient temperature must give the lithium battery UPS power supply proper temperature and keep it, in general UPS batteries, the temperature of its environment should be guaranteed to 20-25 degrees Celsius Between, and lithium battery UPS can work normally at -20-60 degrees Celsius, do not require air conditioning, reduce equipment installation fees, maintenance, electricity bills. Second, the regular inspection period should be performed regularly check the end voltage and internal resistance of each unit battery.
During operation, the lithium battery UPS power supply is eliminated due to the above-mentioned imbalance generated by each unit battery characteristics over time, it is impossible to rely on the charging loop inside the UPS battery, so it has a significant unevenness of this characteristic. The battery pack, if it is not in time, it will become more and more serious. Third, under certain conditions, you need to re-floating the lithium battery UPS power stop for more than 10 days.
Before you replay the machine, the UPS power supply should be started under the conditions that do not load to use the charging loop in the machine to float the lithium battery 10 ~ 12h. Also overloaded. The UPS power supply battery is in a floating state without the discharge process, which is equivalent to the "storage of storage" state.
If this state is too long, the lithium battery has not been scrapped due to "storage too long", which is mainly manifested as an increase in the internal resistance of the battery, and the internal resistance can reach a few Ω. Fourth, it is necessary to reduce the service life of the depth discharge lithium battery UPS power supply is closely related to the depth of it is discharged. The lighter the load of the UPS power supply, the larger the use of the lithium battery, the larger the ratio of the lithium battery and its rated capacity.
V. VIII Power supply peak charging to users of lithium battery UPS power supply or frequently power outage, to prevent UPS batteries prematurely damage due to lack of long-term charging, should be fully utilized (such as late night) Charging the battery to ensure that the battery has sufficient charging time after each discharge. Generally, after the battery is discharged, it is charged to 90% of the rated capacity to at least 10 to 12 h.
6. When you need to use the adapter charger to charge the lithium battery UPS power supply using a constant voltage cut-off charging loop, be careful not to adjust the battery voltage too low protection work points, otherwise, it is easy to generate overflow charging in its initial charging. Of course, it is best to use a charger that has both constant current, and constant pressure.
Summary: The lithium battery has life expectancy, and the correct use method can more effectively extend the service life of lithium battery UPS power supply, reduce battery loss, save funds. What are the operating modes of the lithium battery UPS power supply? 1 Using electric power interruption; it is necessary to emphasize that the uninterruptible power supply system will work when it is power outage. If the voltage is too low or too high, the momentum, etc.
is enough to affect the normal operation of the equipment, lithium Battery UPS systems are in operation, providing stable and clean power for load devices. 2, UPS power supply mode When the line UPS emergency power is overload, bypass command (manual or automatic), the inverter overheat or machine fault, the UPS power supply generally converts the inverter output to bypass output, that is, the main electricity Direct power. Due to bypass, the UPS output frequency phase needs to be the same as the medium-speed frequency phase, and thus the same locking technology ensures that the UPS power output is synchronized with the mains.
If the lithium battery UPS is overloaded, it is necessary to reduce the load, otherwise the bypass shorter will automatically cut off output. 3 Continue to use to achieve continuous power supply. 4, UPS power supply Lithium battery bypass maintenance mode When the UPS power battery is maintained, by manually set the bypass to ensure the normal power supply of the load device, when the maintenance operation is completed, restart the UPS power supply, at which time the lithium battery UPS power is turned to normal operation.
Lithium battery UPS application scenario: In the current UPS power battery supply field, lithium battery UPS has become a new type of way, is widely used in various fields, such as data centers, industrial equipment, communication base stations, aerospace, computer rooms, fire emergency emergency emergency , Anti-risk disaster, etc.
