When the battery module is discharged at a rate of 2C, the flow rate is no less than 12 L/h. In addition, when the range of flow rate is 12 ∼ 20 L/h, Z-LCS, F1-LCS or F2-LCS should be adopted. When the range of flow rate is higher than 20 L/h, four kinds of liquid cooling systems can be used.
Four cooling strategies are compared: natural cooling, forced convection, mineral oil, and SF33. The mechanism of boiling heat transfer during battery discharge is discussed. The thermal management of lithium-ion batteries (LIBs) has become a critical topic in the energy storage and automotive industries.
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.
The maximum temperature of the battery under two-phase liquid-immersion cooling remained below 33 °C during the test, and the temperature fluctuation of the battery was <1.4 °C, which was very beneficial to the efficiency and safety of the battery. Fig. 10.
Recently, the direct liquid-cooling technology for battery thermal management has received significant attention. The heat generated from the battery is absorbed directly by sensible (single-phase) cooling or latent heat (two-phase) cooling of the liquid with no thermal contact resistance.
It is thus recommended as the best cooling system in this work. The F2-LCS fully meets the temperature requirements of the battery module at a charge and discharge condition of 1C, while the temperature difference between batteries should be reduced in 2C discharge conditions.
