EMS-GRIVORY wins three SPE Automotive Awards

The battery management module was developed for the Mercedes-Benz EQE. The two orange-colored covers are made of Grilon BG-30 FR, with rigidity, high flowability, flammability in accordance with UL 94 V0 and high dielectric strength.

The overmoulded busbars are made from an impact-resistant Grilon TSGZ-15. The high elongation at break of the EMS polyamide prevents the formation of cracks due to the different thermal expansions of copper and plastic at -40°C to +120°C.

The covers of the busbars are made of Grilon TS V0. The unreinforced polyamide allows the components to be clipped together fully automatically. The extruded busbars are coated with a layer of Grilamid XE 3817, which was specially developed for adhesion to metals.

With outstanding elasticity and adhesion of the EMS polyamide, there is no detachment during the 3D forming process. The material also has excellent ageing resistance for over 3000 hours at up to 125°C. All components are mounted on a 1.2m long structural beam, which is made from a very easy-flowing Grilon BG-30 S.

This innovative return-line is designed for V8 diesel engines, made from the high-temperature-resistant polyamide Grivory HTV-4H1. By substituting aluminum, a weight saving of 85% is achieved while maintaining a long service life.

The high-voltage connector, currently the smallest and most compact one on the market, has been developed for contacting high-voltage cables in electric cars up to 1000 V.

The EMS polyamide Grilon XE 16076 with 60% glass fiber reinforcement, specially developed for this application, has 40% better flowability than conventional PA6 grades. The color is color-stable even after 1000 hours of storage at 150°C and allows easy laser marking. The excellent strength of the material prevents deformation while remaining flexible enough to operate clips and latches without tools.

The material is also halide-free, contains no metallic components and therefore ensures permanent insulation without the occurrence of contact corrosion.
