Battery thermal management relies on liquid coolants capturing heat from battery cells and transferring it away through a closed-loop system. As batteries generate heat during operation, coolant flowing through cooling channels absorbs thermal energy and carries it to a heat exchanger or radiator. Fans then exhaust the heat so the cooled fluid can recirculate
