Coolant improvement The liquid cooling system has good conductivity, allowing the battery to operate in a suitable environment, which is important for ensuring the normal operation of the lithium-ion battery.
Liquid cooling, due to its high thermal conductivity, is widely used in battery thermal management systems. This paper first introduces thermal management of lithium-ion batteries and liquid-cooled BTMS.
The advantages and disadvantages of different coolants, cooling plates, channels, heat exchanger jackets, and hybrid systems are analyzed and conclude that improvements in coolants, cooling channels, and liquid-PCM mixed cooling are the most effective ways to improve the performance of lithium-ion batteries. 2.
Under this trend, lithium-ion batteries, as a new type of energy storage device, are attracting more and more attention and are widely used due to their many significant advantages.
However, lithium-ion batteries are temperature-sensitive, and a battery thermal management system (BTMS) is an essential component of commercial lithium-ion battery energy storage systems. Liquid cooling, due to its high thermal conductivity, is widely used in battery thermal management systems.
