How to standardize the maintenance of UPS lithium battery?

　　In the next few months, the output of industrial lithium battery packs will decrease, and the price may fluctuate slightly. However, due to the variety of raw materials, although the price of industrial lithium batteries will fluctuate to a certain extent, it is not easy for indoor space to fluctuate greatly, which is also closely related to the development trend of this field at this stage. At this stage, the price of the popular lithium iron lithium battery component exceeds 90000 yuan/ton. For some small retail investors, it is possible to improve the indoor space, but for some large customers, these aspects have no advantages. Today, Tuopai New Energy will take you to know how to standardize the maintenance of UPS lithium battery?

　　1. When using a lithium ion UPS, pay attention to various main parameters of the UPS, such as the type of input working voltage, type of output waveform, power, long power supply system time, conversion time, well-known lithium ion brands, noise, equipment volume, net weight, etc. All kinds of UPS are not suitable for full load operation. More than 20% of the output power capacity shall be embedded, and the load shall operate between 40% - 60% of the rated power of ups

　　2. When the UPS power supply is not used for a long time, it should be turned on each time. For the reserved UPS, it is recommended to keep the UPS in the inverter operation state for at least 2-3 minutes each month, so that * * * can charge the battery and increase the service life of the rechargeable battery. When charging the battery, try to prevent the battery from charging over-current and over-voltage. Moderate charge and discharge help to charge the battery

　　3. Grasp the basic knowledge of lithium ion UPS, carefully read the operating instructions of mechanical equipment, and understand the contents of various warning messages, warning codes, meaning of display lights, causes and preventive measures. Understand the functions of various power switches and keys on machines and equipment. Understand the actual operation of various ups, and clearly understand their connections and interrelationships

　　4. Strengthen daily inspection and maintenance, check whether the equipment has alarm, peculiar smell and abnormal noise, check whether the connector is loose and hot, check whether the refrigeration cooling fan operates normally, check whether all signs of mechanical equipment are normal, and solve the problem immediately

　　5. Maintain proper operating temperature. Working temperature is the key factor affecting the service life of lithium battery ups. The best operating temperature specified by the rechargeable battery manufacturer is generally between 20-25 ℃. Once the operating temperature exceeds 25 ℃, the number of battery cycles will be

　　6. Reduce by half. Replace the old and damaged rechargeable batteries immediately. In the continuous operation and application of lithium ion UPS power supply, it is difficult to avoid damaging some rechargeable batteries due to differences in characteristics and quality. When one or more rechargeable batteries in the lithium battery pack are damaged, the maintenance personnel shall dispose of each rechargeable battery and conduct regular inspection and testing to remove the damaged rechargeable battery

　　7. The natural environment where switching power supply is used shall have good natural ventilation, which is conducive to heat dissipation and keeps the natural environment clean. Do not carry magnetic induction loads, such as cash counters, fluorescent tubes, central air conditioners, etc., to avoid damaging the UPS power supply

　　8. Do not turn the ups off and on frequently. Normally, the UPS power can be turned on again after 6 seconds. Otherwise, the UPS power supply is likely to be in the state of "unsuccessful startup", that is, the UPS power supply is not in the state of voltage output or inverter power output

　　9. Maintain UPS power supply. There is dust in the equipment. Measure the working voltage of the lithium battery pack accurately, check the operation of the cooling fan, and check and adjust the main parameters of the UPS power system software.
