At its core, the battery capacity needed for a UPS project is determined by the power demand and required backup time, adjusted by efficiency losses and usable battery capacity limits. The basic formula is:
Series: Divide the DC bus voltage by nominal cell voltage (2.0 V for lead-acid). Parallel: Divide the total required Ah by the Ah of one string. 5. What is the maximum Depth of Discharge (DOD) for UPS batteries? Exceeding these values regularly shortens battery life significantly. 6. How does temperature affect UPS battery capacity?
The backup time can be calculated using the following formula: Backup time (minutes) = Battery capacity (Ah) x battery voltage / Load power (watts). Here are some key factors to consider: Battery capacity: Calculate the battery capacity of the UPS, which is typically measured in ampere-hours (Ah).
UPS sizing calculation will determine the ratings of the main UPS system component : Rectifier battery bank inverter in addition, the calculation result will also help determine the indicative dimensions of the equipment (e.g. size of battery banks )for preliminary layout purposes. When to do calculation ?
The following parameters must be determined before any UPS battery sizing: The standard approach to calculate required battery capacity (C_AH) in ampere-hours: Where: Example Temperature Correction Factors (IEEE/IEC) Below is a reference table for typical configurations.
To calculate the required UPS capacity, you need to calculate the total power consumption of your equipment, including the peak power requirements. This can be done by using the following formula: UPS capacity (VA) = Total load power (watts) / efficiency. Here are some key factors to consider:
