How accurate is the reference design of a power battery pack?

The test result verified the accuracy and the rationality of the model, but it also showed that the reference design could not reach the qualified standard of thermal performance of the power battery pack. Based on the heat dissipation strategy of liquid cooling, a novel improved design solution was proposed.

Why do EV batteries need tab cooling?

Also, the axial thermal conductivity of a battery is more than the radial value, so heat is transferred axially at a higher rate. In the automotive sector, a cycle ends when the maximum usable battery capacity of an EV battery pack reaches 80%. In effect, tab cooling realizes to improve the useful life of a battery by three times.

How does a battery module liquid cooling system work?

Feng studied the battery module liquid cooling system as a honeycomb structure with inlet and outlet ports in the structure, and the cooling pipe and the battery pack are in indirect contact with the surroundings at 360°, which significantly improves the heat exchange effect.

What is the temperature distribution of power battery pack based on reference design?

The temperature distributions of the power battery pack based on the reference design are shown in Figure 10. At the end of the discharge, the temperature of the upper battery module was higher, the heat distribution of the battery module 7 was more concentrated, and the maximum temperature approximately reached 43.4 °C.
