A Battery Energy Storage System, or BESS, keeps every cell in a battery pack balanced by controlling when and how much each cell charges and discharges, so power is there whenever you need it. An EMS app matters because it turns detailed battery data into easy-to-read screens, sends clear alerts when something needs attention, and lets you set charging times with just a few taps.

The system marks Arbin’s first commercial product—rather than another lab/industrial battery tester aimed at engineers—the EMS app must serve a broader audience, from facility managers to someone who are not a battery expert.
