Analysis of UPS battery protection solutions

UPS battery protection solutions1. Power-on sequence. In order to prevent the damage to the UPS inrush current from starting the load at the moment, the power supply UPS should first be in the operation process, let it be in the bypass operation condition, and then the load should be turned on one by one, in order to Prevent the influence of the load current in the UPS and prolong the service life of the UPS. The shutdown sequence can be seen as the reverse process of the startup sequence, first turning off the loads one by one, and then turning off the UPS. 2. Before turning on the machine, first confirm whether the polarity of the input power connection is correct to ensure personal safety. Note that the total power of the load should not be greater than the rated power of the UPS. The UPS should be prevented from operating under overload conditions to ensure that the UPS can operate normally. 3. Turn off afterwards. When the power is cut off, the UPS battery pack will be automatically powered on and turned off. Do not re-energize the UPS battery pack to avoid damage to the battery due to over-discharge. When the power supply is replaced with a UPS battery pack due to abnormal conditions, the load should be turned off in time, and the power should be turned on after the power supply returns to normal. 4. Your environment is similar to the computer's working environment, and UPS has the same requirements for ambient temperature, which is not very high. Under normal circumstances, the normal working time of UPS is 0-40. However, dust prevention also bothers UPS. The operating environment of UPS requires cleanness, less dust and no gloss. Dust and damp environment will cause UPS to work abnormally. The UPS battery pack requires a higher temperature. The standard operating temperature is 25°C, and it is generally best not to exceed 15~30°C. 5. Battery protection The UPS battery will have self-discharge. If it is stored for a long time, it will not cause damage to the battery, so it should be charged and discharged regularly. If used, freedom is to protect the battery that absorbs electrolyte. During normal use, no gas will be generated, but if the user uses improperly, the battery is overcharged and the gas occurs, and the internal pressure of the battery is increased, which will cause the battery to explode in severe cases. , Deformation, leakage, or even breakage, if the user finds such a phenomenon, he should replace the battery immediately. 6. Pay attention to safety. Due to the high voltage of the UPS battery, there is a certain risk of electric shock to the human body, so the loading and unloading of the conductive connection and the output line should be safe. The thing should be insulated use, especially the output contact should be set to prevent electric shock. 7. During the UPS charging process, if the charging voltage is too high, the battery pack will be overcharged; otherwise, the battery pack will be undercharged. When the charging voltage is abnormal, the battery device data may malfunction. Therefore, when installing the battery pack, you must pay attention to the correctness of the battery standards and quantity. Different standards and different brands of batteries should be avoided as much as possible. It is also best not to use inferior products with external chargers. 8. The charging current is similar to the voltage requirement of UPS, and excessive current should be prevented when charging and discharging the UPS battery pack. Although sometimes the UPS battery can accept a certain level of high current, it should be prevented in actual operation. Otherwise, the battery board will be deformed and the internal resistance of the battery will increase. When the battery capacity is severely reduced, the battery life will be greatly shortened. The above is the current status and solutions of UPS battery protection in China. It analyzes the general normal use of UPS. Its battery life is 3 to 5 years. However, there are currently some problems that exist in the corresponding part of UPS batteries that have been used for less than 1 year. This is important because of lack The day after the necessary protection is formed. It is worth noting that many users do not know the health status of their UPS battery due to lack of necessary test protection, leaving hidden dangers for the normal operation of the UPS system.
