Covers and structural components for charging wallboxes
Potential new applications for charging wallboxes include covers and structural components. As visible parts, covers have to be not only easily paintable and weathering- as well as UV-resistant, but also have a low tendency to warp. This requirements profile is met by Pocan C1203, for example, an unreinforced blend of polycarbonate and polybutylene terephthalate (PBT).
Typical requirements for structural components such as mounting systems for wallboxes include high flame retardancy, weathering resistance, and creep resistance paired with high toughness and a low tendency to warp. “The material of choice here is the highly reinforced, and thus extremely strong and rigid, Durethan BKV45FN04,” says Luers. The halogen-free flame-retardant polyamide 6 displays a high of 600 V (CTI A) and achieves UL 94 V-0 classification at 0.4 millimeters.
Floor and vehicle pads for inductive charging systems
Another current development trend is inductive and wireless charging of vehicle batteries. The flat floor and vehicle pads that are required here and accommodate – among other things – the inductive charging coils have to be constructed from materials that are not only fire-resistant and mechanically strong, but also have a low tendency to warp and exhibit high dielectric strength. The materials also have to be light- and weathering-resistant, with their properties remaining highly stable across a temperature range of -45 to +125 °C. One material that can be used for floor plates is the glass-fiber- and glass-ball-reinforced polyamide 6 Durethan BG30XFN01. It displays excellent flow properties and is also extremely strong and resistant to warpage. It passes the UL 94 test with V-0 with a test body thickness of 0.75 millimeters. It also has a UL f1 listing for use in outdoor applications exposed to UV and water.
HiAnt services across the entire development chain
HPM supports customers along the entire development chain of components used in the charging infrastructure for electric mobility. Services include developing application specific materials and optimizing processing. The package also includes engineering services during component design such as CAE simulations, mold flow calculations, and various finished part testings. “We also perform standard-compliant tests for UV resistance and fire behavior such as glowing wire tests in accordance with IEC 60695-2-13,” says Luers. The scope of services also encompasses electrical tests such as for dielectric strength in accordance with IEC 60243-1.
