Passive and active air cooling of a battery module

A module-level thermal scope compared passive heat rejection and forced-air cooling to assess transient temperature development and inlet/outlet routing.

Engineering question

Heat generation, operating profile and a compact enclosure had to be translated into a cooling concept that made critical regions and the required air path assessable.

Model & approach

  • Structure heat generation and transient operating profiles as thermal sources
  • Model passive and forced airflow including opening-layout variants

Boundary conditions

  • Internal conduction and heat rejection from the module
  • Project-specific operating profiles, openings and active airflow

Results of the assessment

  • The archive documents the technical scope, preliminary heat balance and detailed design inputs.
  • No final temperature assessment or released cooling architecture was present.

Engineering consequence

The model was intended to support selection between passive and active cooling and development of the opening layout.

Context

The reviewed archive evidences the task and model scope but contains no final result report. No performance or implementation claim is therefore published.
