ups选电池方法（UPS battery selection method）

ups选电池方法（UPS battery selection method） Calculation method of UPS matching battery I. calculation of UPS backup battery example 1 1. Considerations: DC voltage: 384V Rated output power: 60KVA Power factor: 0.8 Efficiency: 92% Standby time: 30 minutes Set the final voltage of the battery: 1.75V 2, calculation steps: the battery to sunlight battery A400 (12V) series for example Battery number =DC voltage / battery voltage =384/12=32 Check whether the battery voltage is in the DC voltage range (320-480V) when the 32 batteries are connected in series 1.75V (battery discharge final pressure) *6 (number of 2V cells per battery) *32=336V320V 2.35V (battery average impulse voltage) *6 (the number of 2V units per battery) *32=451V480V Battery output power = rated output * power factor / efficiency =60*0.8/0.92=52.17KW The power required for a single battery =52.17KW/32=1.669KW 3. Select batteries According to the battery power / time control table, to find the battery can meet the final pressure =1.75V, in the discharge of 30 minutes, the output power is more than 1.669kw of the battery model; Check the sun A412/180 discharge in 30 minutes, the output power is 1.876kw1.669kw Therefore, the adoption of 32 A412/180 (180AH) can meet the requirements of UPS system design. Two, UPS backup battery calculation example 2 1. Considerations: DC voltage: 384V Rated output power: 120KVA Power factor: 0.8 Efficiency: 92% Standby time: 60 minutes Set the final voltage of the battery: 1.75V 2, calculation steps: the battery to sunlight battery A600 (2V battery) series for example Battery number =DC voltage / battery voltage =384/2=192 Check whether the battery voltage is in the DC voltage range (320-480V) when the 32 batteries are connected in series 1.75V (battery discharge final voltage) *192 (battery number) =336V320V 2.35V (battery average impulse voltage) *192 (battery number) =451V480V Battery output power = rated output * power factor / efficiency =120*0.8/0.92=104.35KW The power req
