Lithium battery hydraulic system structure

What are the thermal-hydraulic characteristics of battery thermal management system?

The thermal-hydraulic characteristics of the battery thermal management system are studied based on CFD simulations. The non-dimensional j / f factor is developed and adopted to evaluate the heat transfer ability and friction loss of different designs.

How do stacked lithium-ion batteries work?

In commercial lithium-ion battery modules for new energy vehicles, rectangular lithium-ion batteries are stacked with the cooling plates staggered, with the upper and lower surfaces of the cooling plates directly contacting the individual battery cells, thus increasing the heat transfer area of the batteries, as shown in Fig. 1 a.

What is a lithium ion battery?

The lithium-ion (Li-ion) battery, which has the excellent characteristics of long cycling life, high energy density, low self-discharge loss, and high charge–discharge efficiency [ 7 ], is the dominant choice for power supply and energy storage [ 8 ].

Does flow channel design affect thermal performance of prismatic Li-ion battery?

Results In the present study, the thermal performances of several flow channel designs for prismatic Li-ion battery thermal management are studied. Specifically, the effects of the main flow direction, the addition of intersecting channels, and the inlet and outlet distribution are examined.

Do li-ion batteries need thermal management?

Authors to whom correspondence should be addressed. Liquid thermal management is the prevailing method to maintain the operating performance and safety of Li-ion batteries. However, a better heat transfer performance is often accompanied by a higher power cost for liquid-based cooling methods.
