The BETA TMS manages battery temperature during aircraft charging to enable the highest charging speeds and the shortest turn-around times. It works by circulating a glycol-water mixture through the aircraft’s on-board battery packs. The system uses two closed-loop heat- exchange circuits that include 1) a chiller unit and 2) a BETA TMS Cube. Together, these components actively condition aircraft batteries as they charge, preserving battery performance and safety while accelerating charge operations.
