How do you determine the thermal efficacy of a battery cooling system?

Two pivotal metrics for evaluating the thermal efficacy of a battery cooling system are the maximum temperature rise and temperature differential. A significant increase in the maximum temperature suggests inadequate cooling, potentially resulting from a low ambient temperature or an inefficient heat removal process.
