What are the calculation methods of UPS battery

1. The constant current mode calculation is based on the principle of energy conservation: Cu003d(PL*T)/(Vbat*η*K) C is the battery capacity (Ah); PL is the UPS output power (W); T is the battery backup time (h ); Vbat is the battery pack voltage (Vdc); η is the UPS battery inverter efficiency (0.90-0.95, selected according to the model); K represents the battery discharge efficiency. The Ah number of the battery is determined according to the calculation result, and the appropriate configuration is selected according to different brands of UPS batteries. 2. Constant power calculation formula Wu003dPLu0026pide; (N*6*η) (watts/cell) PL is the rated output active power of the UPS (KW); N is the number of batteries of 12V; Vf is the rated voltage of the battery pack; η is Inverter efficiency. That is, first calculate the required power of the single battery, and then find the battery model that can meet the requirements through the constant power discharge table supplied by the battery manufacturer. The termination discharge voltage is determined according to 1.75V/cell. Usually the power meter given by the battery manufacturer is the power of a single 2V/Cell, which means watts/cell. The power meter given by some manufacturers is watts/block, so you have to multiply it by a factor of 6. The battery is an important part of the UPS power supply system. Due to the battery itself or management reasons, many UPS faults are caused by the battery. Therefore, it is necessary to enhance the knowledge of battery characteristics, select and use the battery correctly, and extend the service life of the battery as much as possible.
