TBC stands for Thermal Battery Cell. A TBC is a type of battery cell that uses a thermal management system to keep the cell within a certain temperature range. The thermal management system can be either active or passive. Active systems use pumps and/or fans to circulate coolant around the cell, while passive systems rely on convection and/or phase change materials (PCMs) to regulate the cell temperature.
TBCs are often used in high-power applications where it is important to maintain a stable operating temperature. For example, TBCs are commonly used in military and aerospace applications, as well as in electric vehicles (EVs).
