| Résumé : |
Thanks to their technical properties, polycarbonates are predestined to be used as cell holders and housings of lithium-ion batteries for hybrid and purely electric vehicles. An exemplary development shows how material-compatible component design and the rheological, mechanical and thermal simulations necessary for this can help. |
| Note de contenu : |
- Tailor-made battery materials
- Evaluating procesing and dimensional accuracy
- Mechanical simulation to prevent fire
- Route, distribute and dissipate heat
- Fig. 1 : Rheological layout of a cell holder. The mostly very-large wall thickness jumps are challenging. In particular, the low wall thickness of sometimes less than 1 mm in the region of the webs quickly lead to problems in filling the molded part, as the melt solidifies quickly
- Fig. 2 : The finite element simulation of the stock test shows the load in the plastics of the battery module; test bench for an actual shock test. The modules are Covestro test vehicles
- Fig. 3 : Simulation of the temperature distribution in a liquid-cooled battery module. The medium flows into the module on the outside left and absorbs the heat of the battery cells
- Fif. 4 : The simulation shows the flow lines of the air and the temperatures of the cells inchromatic gradation |
