For example, a battery cabinet contains 16 pcs of 12V battery, and all of them connect in series, the nominal voltage of this battery cabinet is 192Vdc. It would match the UPS which should connect 16 pcs of battery, battery voltage 192Vdc or charging voltage 218.4.
When we talk about a 12V battery, it means the nominal voltage of this battery is 12V. For most 12V lead-acid batteries, the charging voltage is around 13.65~13.7V. Therefore, the charging voltage of 16 pcs of battery connected in series is 218.4~219.2V. This value should be able to be found on the datasheet of UPS.
One cabinet should be able to hold at least one complete string of cells. Best practice is that strings should not be split between two cabinets in order to ensure reliability of the entire string. Figure 1 - Battery cabinet with top terminal cells A battery disconnect switch should be located as closely as possible to the end of a string.
It is therefore helpful to know the capacity of a battery in kWh. This is worked out as follows: Capacity in kWh = (Capacity in Ah x Operating Voltage (V)) / 1,000 So if a battery has a nominal capacity of 500Ah and a nominal voltage of 12V, the overall nominal capacity in kWh is 500 * 12 = 6,000Wh, or 6kWh.
So if a battery has a nominal capacity of 500Ah and a nominal voltage of 12V, the overall nominal capacity in kWh is 500 * 12 = 6,000Wh, or 6kWh. Remember the battery only has this capacity when operating at the nominal discharge current … The power output of the battery in Watts is given by Discharge current (A)* Voltage (V)
It would match the UPS which should connect 16 pcs of battery, battery voltage 192Vdc or charging voltage 218.4. When we talk about a 12V battery, it means the nominal voltage of this battery is 12V. For most 12V lead-acid batteries, the charging voltage is around 13.65~13.7V.
