One eBox manages 250 wireless moduleor sensors.NOTECurrently, eMeter only can be used for battery sting with rated 48V voltage.4.2 Application ScenariosThis section briefly describes the scenarios requiring the eBIMS and typical eBIMS deploymentscenarios.Scenarios Requiring the eBIMSTypical scenarios:1. Outdoor sites encounter network problems because battery aging due to overcharge/overdischarge/undercharge/underdischarge deteriorates backup time. In this case,maintenance costs are increased because multiple site visits are required to confirm thebattery location and quantity, check battery performance, and determine whether to replacebatteries.2. Routine testing and inspection of batteries inside equipment rooms require much humanpower. Moreover, one-by-one battery check cannot accurately determine the battery status,causing much waste.Deployment Inside an Outdoor CabinetThe eBats and eBox are deployed in an outdoor cabinet. They communicate with each otherwirelessly. The eBox transmits collected battery data to the server. Users log in to the server toperform real-time monitoring and operations.
