With the increasing application of the lithium-ion battery, higher requirements are put forward for battery thermal management systems. Compared with other cooling methods, liquid cooling is an efficient cooling method, which can control the maximum temperature and maximum temperature difference of the battery within an acceptable range.
Latest researches on battery liquid cooling system are summarized from three aspects. Properties and applications of different liquids are compared. Advantages and disadvantages of the different configurations are analyzed. Differences in the design scheme between direct and indirect cooling system is compared.
The Chevrolet Volt and BMW i3 and i8 also use liquid cooling systems for battery thermal management to avoid excessive battery temperature . In addition, 3M has developed a battery direct liquid cooling system for electric vehicles, which immerses the battery module directly into the coolant, showing an excellent cooling effect .
It was found that the cooling performance of the system increased with the increase of contact surface angle and inlet liquid flow rate. For the preheating study of the battery system at subzero temperature, they found that a larger gradient angle increment was beneficial to improve the temperature uniformity.
However, extensive research still needs to be executed to commercialize direct liquid cooling as an advanced battery thermal management technique in EVs. The present review would be referred to as one that gives concrete direction in the search for a suitable advanced cooling strategy for battery thermal management in the next generation of EVs.
