UPS battery configuration method
2. Calculate DC power demand;
2. Find suitable batteries to meet DC power demand;
3. Adjust the number of batteries and groups to meet the requirements of 1 and 2;
General principle:
1. The number of groups is generally not more than 4 groups, and 2 groups are appropriate;
2.12V battery is typically lowered by 2V battery, generally preferably 12V battery;
3. If the number of UPS battery is adjustable, do not configure to a minimum;
4. Constant power calculation methods are more accurate than constant current calculation methods.
calculation steps:
Step 1: Determine 7 parameters
These parameters are determined by UPS and user requirements.
Group 1 set
Step 2: Calculate DC power requirements (monomer)
Step 3: Select the battery
In your demand time column, lookup is greater than or equal to DC power (the result of the second step) requires a suitable battery model.
But the maximum power C & D12-775A DNT can not meet the requirements (776.6 <1418.44)
Step 4: Adjust the number of groups recalculated
2 groups can meet and exceed the requirements (776.6> 709.22)
Step 5: Determine the discharge capability of this battery in this discharge time period
Step 6: What is the expected backup time of this group of battery configuration?
Step 7: Adjust the number, optimization plan
