Can liquid immersion technology improve battery thermal management?

The promising application of liquid immersion technology in electronic equipment has also garnered increasing attention for its potential in battery thermal management. Power battery immersion liquid-cooling technology involves directly immersing the battery in dielectric liquid to dissipate heat through convection or phase-change heat transfer.

What are liquid cooling-based battery thermal management systems (BTMS)?

Liquid cooling-based battery thermal management systems (BTMs) have emerged as the most promising cooling strategy owing to their superior heat transfer coefficient, including two modes: indirect-contact and direct-contact. Direct-contact liquid BTMs, also referred to as immersion cooling systems, have garnered significant attention.

What is immersion cooling?

Unlike indirect cooling methods that use cold plates or tubing, immersion cooling eliminates thermal resistance between the battery and the cooling medium, enabling superior heat transfer performance and uniform temperature distribution.

Is liquid immersion cooling a good thermal management strategy?

Liquid immersion cooling offers clear thermal performance advantages, but like any thermal management strategy, it brings its own set of design and engineering trade-offs. However, many of the so-called limitations are now being actively addressed through smart design innovations and material advances.

What are the benefits of liquid immersion cooling?

Liquid Immerison cooling. The key benefits of Immersion cooling are well known which are: Enhances thermal uniformity (Temperature Gradient within a battery) – reducing cell-to-cell temperature variations. Improves cooling efficiency – high heat transfer coefficient of liquid coolant.

Is liquid immersion cooling a good option for lithium ion batteries?

With higher energy density and fast-charging demands in modern EVs and energy storage systems, traditional air and indirect liquid cooling methods struggle to keep up with thermal runaway risks and non-uniform heat dissipation.
