Simulation as a design and validation tool<\/h2>

Simulation is used at EXOES as a design and validation tool. It allows digital experimental designs to be created where testing would take too long and be too numerous and costly to obtain an equivalent quality result. This is possible if and only if the simulations are correlated, which is the case at EXOES.<\/p>

An example of battery simulation: modelling prismatic, cylindrical or pouch cells for different electrochemicals: NMC, LTO, etc.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

A thermal model coupled with an electrical model<\/h2>


A complete electrical temperature test<\/strong>, carried out in our laboratory, allows first of all to characterize an electrical model of a temperature-variable RC cell. Afterwards, a complete dismantling of a cell is carried out in our premises. The geometry of the cell is reconstructed in 3D in SolidWorks and exported to GEM3D, the meshing tool associated with Gamma Technology Suite.<\/p>

After simplification, a thermal model<\/strong> coupled with an electrical model is created. This cell model can either be used directly to determine the performance of cooling architectures (thermal inertia, air, cold plate, immersion, etc.) or be assembled into a module to study the propagation of a thermal runaway and the impact of different design options.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

Optimisation of fluid flows<\/h4>

We adjust the velocities and pressure drops within the batteries and cooling loops. This allows us to distribute the fluid evenly and thus ensure temperature homogeneity and uniform ageing for the cells.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t
