The disclosure relates generally to methods and systems for determining heat transfer rates between battery pack and coolant channel with varying coolant flow rate in a real-time. A lumped conductance generated between the battery pack and a coolant channel is used to determine the heat transfer rates between the battery pack and the coolant channel. Conventional techniques for calculating the lumped conductance between the battery and the coolant channel either use experimental methods or rely on the heat transfer correlations in simple geometry. The present disclosure calculates the lumped conductance by understanding an internal structure of a cylindrical battery pack using a high-fidelity computational fluid dynamic (CFD) simulation. This will help in determining the heat transfer rates of the battery pack in the real-time at the battery core especially when the coolant channel side hydrodynamic conditions change with time due to the variable coolant flow rates.
