EMC for EVs: Understanding electromagnetic compatibility

Engineers who design power electronics supplied by the mains have had to contend with meeting various electrical noise and safety standards for decades now, but their counterparts in the automotive industry were mostly free to do as they pleased. This was mainly because 12 V isn’t considered a shock hazard and cars are effectively rolling… Read more »

Freudenberg launches new conductive seals for electric powertrains

Freudenberg Sealing Technologies is launching a new line of conductive seals that are designed to allow for durable connections between housings and shafts, while preventing bearing damage from electricity and electromagnetic radiation. The first functional models should be available within the next few months. Tim Leichner, Head of Strategic Product Advance Development at Freudenberg, said,… Read more »

Wallner Expac launches Microform expanded metal for batteries and EMI shielding

Expanded metal developer Wallner Expac has added to its product line MicroForm, an expanded metal for applications such as support foils for batteries, EMI/RFI shielding, and microfiltration. MicroForm can be manufactured into light- and heavy-gauge variants. The LWDs (long way of designs) can be expanded from 0.125 inches down to 0.05 inches using materials with… Read more »

Dow’s new conductive adhesive provides electromagnetic shielding

Dow’s new DOWSIL EC-6601 Electrically Conductive Adhesive is a silicone adhesive that’s designed for electromagnetic compatibility. It combines shielding against electromagnetic interference across a range of frequencies with durable mechanical and conductive properties over time. Dow showcased the new adhesive at a recent battery expo, along with the company’s EA-4700 CV Adhesive, which bonds metals… Read more »

Freudenberg develops lightweight plastic housing to seal against electromagnetic radiation

Researchers at Freudenberg are developing a plastic housing material for EV electronics as an alternative to heavier and more costly aluminum. To protect against electromagnetic waves that can disrupt signal flow in microprocessors and transmitter-receiver systems, EV makers typically encase electrical components in conductive metal housings, usually aluminum. Freudenberg says the additional weight of the… Read more »

Infolytica has released new versions of its MagNet, ElecNet, ThermNet and OptiNet simulation software. Upgrades in version 7.8 include improved nonlinear material treatment in AC/time-harmonic simulations and expanded circuit modeling tools for complex control systems. Infolytica’s suite of computer-aided engineering software is designed to handle the most complex electromagnetic and electric field simulations. Engineers, scientists… Read more »

Study finds electromagnetic fields in EVs not a safety issue

An EU-funded study has found that electrified vehicles do not expose passengers to higher electromagnetic fields than those recommended in international standards (and neither do ICE vehicles). The study EM Safety, which involved the independent research organization SINTEF and nine other European companies and research institutes, is the most comprehensive ever carried out in this… Read more »
