What is a battery energy storage system?

Battery energy storage systems (BESS) stabilize the electrical grid, ensuring a steady flow of power to homes and businesses regardless of fluctuations from varied energy sources or other disruptions. However, fires at some BESS installations have caused concern in communities considering BESS as a method to support their grids.

Why do you need a battery cabinet?

This best practice is intended to protect a worker from exposure to lethal voltage or arc blast in the event of a fault inside the cabinet. Ease of use is one of the principle selling points for battery cabinets. It is convenient to service the equipment when the UPS and the battery(ies) are right next to each other.

Do battery cabinets need to be in a battery room?

Because cabinets can have locked doors, the cabinets do not have to be in battery rooms; they can be installed directly adjacent to the UPS system and/or the information technology equipment. This eliminates the need for long dc cabling. Battery cabinets can be made to be indistinguishable from IT equipment cabinets.

Can you put a battery in an electrical room?

Local or regional codes may dictate whether batteries are permitted in an electrical room. Smaller UPS systems (e.g, up to 250 kVA) are commonly installed directly in the computer room along with their respective battery cabinets. The UPS and/or battery cabinets might be configured to look like standard computer equipment racks.

How do you secure a battery cabinet?

Various approaches to securing a battery cabinet include frames or straps under the raised floor. Under-floor frames are subject to the same building code requirements for fastening to the concrete floor as for racks. They actually raise the center of gravity, thereby increasing the possibility of rocking.

When should a pre-configured Battery Cabinet be acceptance tested?

For example, pre-configured battery cabinets should be acceptance tested at the factory or upon initial installation. The purpose of an acceptance test is to confirm that the battery meets the specified discharge rate and duration. Some batteries are not fully formed until they have been in service for several months.
