How to correctly choose UPS battery capacity

In the UPS power supply system, it can be said that the battery is the backbone of this system. A UPS without a battery can only be called a stabilized frequency power supply. The reason why UPS can realize uninterrupted power supply is because of the battery. When designing a UPS, you should first consider what type of battery to choose, that is, the battery's rated voltage, rated capacity, and how many batteries should be packed. Because the actual usable capacity of the battery is closely related to factors such as the size of the discharge current, the system voltage, the discharge time, the working environment temperature of the battery, the length of the storage time of the battery, the type and characteristics of the load, and so on. The capacity of a battery generally refers to the power output (W) of the battery when it is discharged to 1.75V/cell at a discharge rate of 20h at 20°C. In the UPS system, when the mains power is normal, the mains is the energy source, the UPS is the energy conversion device, the battery is the energy storage, and the subsequent load is the energy consumption source. When the mains fails, the battery is the energy source, and the UPS is the energy conversion For equipment, the load is still the source of consumption. UPS power supply systems play an important role in power supply protection in data centers in various industries. To provide uninterrupted power supply to the load, it must have the function of electrical energy storage. Therefore, the battery has become an important part of the UPS power supply system. Select and use batteries correctly to extend the service life of batteries as much as possible. Therefore, we must first know the purpose and significance of the battery in the UPS power supply system, and then purchase it according to the company's requirements.
