Farasis Vitality, a battery manufacturing firm, Kautex Textron, a provider of power storage techniques, and the Fraunhofer Institute for Excessive-Pace Dynamics goal to make plastic-based battery housings safer via digital design to extend the protection of EVs.
Farasis, which develops and produces lithium-ion battery expertise and pouch cells for electromobility, is growing a simulation mannequin for mapping the thermal runaway of particular person cells and module propagation. The corporate additionally helps all battery subjects inside the three-year SiKuBa challenge, which has obtained €2.6 million from the German Federal Ministry for Financial Affairs and Local weather Motion.
The challenge goals to research the formation and propagation of sizzling fuel and particle flows and their interplay with structural components, transferring the information to simulation fashions. It’s going to additionally assess battery security utilizing numerous load case eventualities, supplies and element design.
Farasis Vitality and its companions will develop an in depth mannequin for simulating thermal runaway, or improve the prevailing fashions inside the firm. These simulation fashions will allow the corporate to realize a faster and safer integration of plastic-based module and pack enclosures.
“Plastic enclosures have many benefits over metallic enclosures. They’re lighter, extra sustainable, and cheaper to provide, and have higher electrical insulation. Within the occasion of a broken cell, the battery housing will be uncovered to huge thermal hundreds if thermal runaway of particular person cells happens because of the harm,” the corporate notes. “The battery housing has a excessive safety-relevant operate on this case, because it comprises the unfold of the ensuing sizzling gasses and particles. One problem, nevertheless, is proving its security, which is complicated and costly.”
