FULL ELECTRIC HVAC AIR CONDITIONER BTMS EFDR SERIES - Battery Thermal Management System

FULL ELECTRIC HVAC AIR CONDITIONER BTMS EFDR SERIES

BTMS : Battery Thermal Management System is a very critical unit for an electric bus. It's duty is to provide a most comfortable temperature climate for the battery unit. Battery units work well at a temperature range of 10-30 deg C, but in cold and hot weather, battery performance declines, and battery cells either become volatile or too dull. BTMS acts lika a nanny to babysit the batteries. It works under the command of BMS, battery management system to output capacity to cool or heat the coolant carrier. A bad BTMS has the potential to lose control of battery climate and thus cause a fire.
