Here, the energy exchange takes place between an induction coil positioned in the ground and a receiver coil mounted in the e-car. For the system to function reliably, the coils must be protected from damage. Glass fiber-reinforced and flame-retardant PA66 is particularly suitable for this, as the example of a current wireless charging system shows. Note de contenu : - Metal alternatives - Material selection criteria - Flowability of the material is decisive - Support for simulation and design - Fig. 1 : Functional principle of the wireless charging system for electric vehicles: among other things, the system can save scarce space, for example in city centers - Fig. 2 : Components of the transmitting (left) and receiving (right) modules of the inductive charging system: the covers must protect the electronics from damage and have flame-retardant properties - Fig. 3 : Stress-strain diagram of the PA66 Radiflam A RV300HF at different temperatures: the material achieves the necessary values for use in the charging modules - Fig. 4 : Deformation of the charging pad in the y-direction during the traverse test: to achieve the required performance, the gating system and the injection molding parameters were optimized - Fig. 5 : The transmitter module and receiver module are now in mass production - Table 1 : Mechanical properties of the PA66 Radiflam A RV300HF - Table 2 : Thermal properties of the PA66 Radiflam A RV300HF - Table 3 : Electrical properties of the PA66 Radiflam A RV300HF En ligne : https://drive.google.com/file/d/1CWXLFDMW3d4yQQzS3qG8ICs9kiOadXod/view?usp=drive [...] Format de la ressource électronique : Pdf Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=38427 [article]
