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.
The present work was compared with recently published work on liquid cooling in Table 3 [ 32, 33, 34, 35, 36 ]. The 18650 cylindrical battery modules are mostly liquid-cooled for side cooling, and configured with parallel or series flow channels. Lv et al.
