With the rapid development of the power industry, the quality of battery manufacturers varies, leading to premature failures before the battery reaches its service life. At critical moments, battery monitoring manufacturers have emerged. Do you know the issues that need to be paid attention to when using UPS power systems?
Due to its high level of intelligence, the UPS power system uses maintenance free lead-acid batteries for energy storage, which brings a lot of convenience to the use of the UPS power system. However, some issues should still be noted during use to ensure the normal use of the UPS power system.
What issues should be noted when using the UPS power system?
1. The UPS power system host does not have high requirements for environmental temperature, and can work normally at+5 ° C~40 ° C. However, it is required to keep the indoor environment clean and reduce dust, otherwise dust and moisture will cause the UPS power host to work improperly. However, energy storage batteries have relatively high requirements for environmental temperature, with a standard operating temperature of 25 ° C, which should not exceed+15 ° C~+30 ° C. If the temperature is too low, when the capacity of the energy storage battery decreases, the capacity will decrease by 1% for every 1 ° C decrease in temperature. The discharge capacity increases with temperature and the service life decreases. If used for a long time at high temperatures, the battery life will be reduced by about half for every 10 ℃ increase in temperature.
2.The parameters set in the power host cannot be changed arbitrarily during use. Especially for the parameters of the battery pack, they will directly affect the service life, but with changes in ambient temperature, corresponding adjustments should be made to the diving voltage. Usually set at 25 ℃, for every 1 ℃ increase or decrease in ambient temperature, the float charge voltage should increase by 18mV (relative to a 12V battery).
3. The UPS power system should have a small power margin according to usage requirements. During use, it is necessary to avoid adding additional high-power equipment at will, and it is not allowed to operate for a long time under full load. However, the nature of the work determines that the UPS power system operates almost continuously. Increasing high-power loads, even when working at basic full load, can cause the host to malfunction and, in severe cases, damage the converter.
4. Due to the high voltage of the battery pack, there is a risk of electric shock. Therefore, safety measures should be applied when loading and unloading conductive connecting strips and output lines. Tools should be insulated, especially the output contacts should have anti touch measures.
5. Whether in float charging operation or charging/discharging maintenance testing, it is necessary to ensure that the voltage and current meet the specified requirements. Excessive voltage or current may cause thermal runaway of the battery, while insufficient voltage or current can result in battery depletion, all of which can affect the battery’s lifespan, with the former having a greater impact.
6. High current charging and discharging of batteries should be avoided. Although high current can be accepted during charging, it should be avoided as much as possible in practical operation, otherwise it will cause the expansion and deformation of battery plates, resulting in the detachment of active materials from the plates, an increase in battery internal resistance, and a higher temperature rise. In severe cases, it will cause a decrease in capacity and premature termination of life.
