What happens if a battery reduces OCV and R_Batt?
IMPORTANT: The reduction of OCV and/or the increase of R_batt cause the reduction of the fault current provided by the battery. Example: For the VRLA type battery close to the End of Discharge (EOD) and End of Life (EOL), due the OCV reduction and resistance increase, the short circuit current can be around 60% of the nominal short circuit current.
Are batteries locked in cabinets or arranged in access-protected rooms?
As per general principle batteries are locked in cabinets or arranged in racks that are housed in access-protected rooms. Only authorized and skilled technicians are accessible to batteries at all times. The risk posed by an open rack battery is lethal (High voltage or arc blast) and hence access should be restricted only to authorized personnel.
What is the nominal voltage of a battery cabinet?
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.
Why should you choose a custom battery cabinet design?
The unique selling point of a custom battery cabinet design is the flexibility it offers concerning simplicity in access. The neat arrangement of cables and grouping them or naming them as per their usage becomes naturally easy.
Is your UPS battery causing load loss?
It’s well understood that the battery in a UPS is the most vulnerable part of the system. In fact, battery failure is a leading cause of load loss. Knowing how to maintain and manage your UPS batteries will extend their life and save you time and potential trouble in the future.
What happens if you don't maintain your UPS battery?
Without regular maintenance, your UPS battery may experience heat-generating resistance at the terminals, or inside the jar improper loading, reduced protection and premature failure. With proper maintenance, the end of battery life can be accurately estimated and replacements scheduled without unexpected downtime or loss of backup power.
