To ensure the safety and service life of the lithium-ion battery system, it is necessary to develop a high-efficiency liquid cooling system that maintains the battery’s temperature within an appropriate range. 2. Why do lithium-ion batteries fear low and high temperatures?
The findings demonstrate that a liquid cooling system with an initial coolant temperature of 15 °C and a flow rate of 2 L/min exhibits superior synergistic performance, effectively enhancing the cooling efficiency of the battery pack.
Direct liquid cooling has the potential to achieve the desired battery performance under normal as well as extreme operating conditions. However, extensive research still needs to be executed to commercialize direct liquid cooling as an advanced battery thermal management technique in EVs.
Using the low mass flow rates of indirect liquid cooling to control the temperature rise and temperature difference within a battery should be avoided.
The uniform temperature distribution within the battery pack is obtained. The thermal management of Lithium-Ion batteries has gained significant attention in the automobile industry. An efficient battery cooling system particularly active cooling techniques have opted as a promising solution in commercial electric vehicles.
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.
