Can a liquid cooling structure effectively manage the heat generated by a battery?

Discussion: The proposed liquid cooling structure design can effectively manage and disperse the heat generated by the battery. This method provides a new idea for the optimization of the energy efficiency of the hybrid power system. This paper provides a new way for the efficient thermal management of the automotive power battery.

What is the energy consumption of liquid cooling at 10 °C?

The energy consumption of liquid cooling at − 10 °C (6.0442E-4Wh) is reduced by a minimum of 30.00%. Furthermore, the optimization strategy led to an increase in T max by a maximum of 14.94% and a minimum of 3.41%.

How does a liquid cooling system affect the temperature of a battery?

For three types of liquid cooling systems with different structures, the battery’s heat is absorbed by the coolant, leading to a continuous increase in the coolant temperature. Consequently, it is observed that the overall temperature of the battery pack increases in the direction of the coolant flow.

What is the heat generation rate of a battery?

As the depth of discharge increases, the heat generation rate gradually decreases to 14.60W. Finally, in the late stage of discharge, the heat generation rate rapidly increases to 48.71W. This is related to the variation of the internal resistance of the battery.

Does liquid cooled heat dissipation work for vehicle energy storage batteries?

To verify the effectiveness of the cooling function of the liquid cooled heat dissipation structure designed for vehicle energy storage batteries, it was applied to battery modules to analyze their heat dissipation efficiency.

Does liquid-cooling reduce the temperature rise of battery modules?

Under the conditions set for this simulation, it can be seen that the liquid-cooling system can reduce the temperature rise of the battery modules by 1.6 K and 0.8 K at the end of charging and discharging processes, respectively. Fig. 15.
