There are two main approaches to cooling in battery packs: passive and active cooling. Passive cooling relies on natural heat transfer without active systems, utilizing conduction, radiation, and convection to regulate temperature. One example is passive air cooling, where air flowing through the vehicle during operation cools the battery pack.

A battery pack and thermal management system developer we consulted emphasises that focusing on cooling (and heating) the battery alone is not the most efficient solution overall.

When air passes through the battery pack, there are two common arrangements: parallel and series. Parallel battery packs are preferred because they face less wind resistance, and each channel has independent airflow. Air-based BTMS can be classified as passive or active preheating, depending on the presence of a heating device [55].
By accurately determining the generation of heat by the li-ion batteries (Q gen) and the dissipation of heat via convection (Q conv), the total heat load on the li-ion battery pack can be calculated. This information is crucial for designing effective thermal management systems and ensuring optimal battery performance, health, and longevity.
