Sammanfattning
The thermal conditioning of battery cells plays a crucial role in ensuring their safety
and maximizing the driving range of electric vehicles. To gain a comprehensive
understanding of battery cell performance under various conditions, testing is conducted
within controlled chambers that replicate real-world scenarios. While battery
packs and modules can function independently during testing, individual cells require
mechanical support. This is where the jig comes into play, serving as a robust
support structure that enables current conduction and facilitates effective liquidbased
thermal conditioning. The objective is to achieve optimal cell climatization
and maintain it at a suitable temperature.
In order to comprehend the thermal properties of the jig when exposed to the heat
generated by the battery cell, Computational Fluid Dynamics (CFD) simulations
are employed. These simulations provide insights into the underlying physics of the
phenomena and aid in the identification of potential enhancements for the jig design
or testing conditions to prevent cell damage. The model can be adjusted to simulate
different temperature scenarios, allowing for a comprehensive evaluation of the jig’s
response under varying conditions.
