How to maintain UPS lithium-ion battery

1. When applying lithium battery UPS, pay attention to various important parameters of UPS, such as inputting working voltage range, output waveform, power, long power supply system time, conversion time, and its famous brand of lithium battery, noise, equipment volume, Net weight etc. All kinds of UPS should not be operated at full load. The output power capacity above 20% should be embedded, and the load should be controlled between 40%-60% of the UPS rated power. 2. When the UPS power supply is not used for a long time, it should be turned on every time. Regarding the reserved UPS, it is recommended to maintain the UPS in the inverter power supply operating state for at least 2~3 minutes every month, in order to reduce the rechargeable battery and add the rechargeable battery life. When charging the battery, try to prevent over-current and over-voltage battery charging. Moderate charging and discharging can help rechargeable batteries. 3. Grasp the basic knowledge of lithium battery UPS, carefully read the instructions of the machine and equipment, find out the meaning of various warning messages, warning codes, display lights, and the reasons and preventive measures. Understand the purpose of various power switches and buttons on machinery and equipment. Understand the actual operation of various UPSs and have a clear grasp of the connection relationship. 4. Improve the usual inspection and maintenance, check whether the equipment has alarms, odors and abnormal noises, check whether the connectors are loose and hot, whether the cooling fan is running normally, and whether the various signs of the machine and equipment are everything Normal, solve the difficulties immediately. 5. Maintain a suitable working temperature. Operating temperature is a key element that endangers the service life of lithium battery UPS. Generally, the best operating temperature specified by rechargeable battery manufacturers is between 20-25°C. Once the operating temperature exceeds 25°C, the number of battery cycles will be reduced by half every 10°C. 6. Immediately disassemble and replace used/bad rechargeable batteries. In the continuous operation and application of lithium battery power supplies, it is difficult to prevent some rechargeable batteries from being destroyed due to the difference in characteristics and quality. When one or more of the rechargeable batteries in the lithium-ion battery pack is damaged, the maintenance staff shall solve each rechargeable battery to carry out regular inspections to remove the damaged rechargeable battery. 7. The natural environment where the switching power supply is applied should be naturally ventilated, which is conducive to heat dissipation and maintains the natural environment clean. Do not bring magnetic induction loads, such as money counters, fluorescent tubes, central air conditioners, etc. , In case the UPS power supply is destroyed. 8. Do not turn off and turn on the UPS power supply frequently. Under normal circumstances, the UPS power supply can be turned on again 6 seconds after being turned off. Otherwise, the UPS power supply is likely to be unsuccessful in starting, that is, the UPS power supply is neither in the voltage output condition nor in the inverter power output condition.
