CoorsTek argues that ceramic bearings are the best fit for EVs The less moving parts in a machine, the better. That’s one often-heard argument for the superiority of electric powertrains over internal combustion engines (ICEs), in which the number of moving components is dramatic. Sure, EVs have a lot of electrons moving this way and… Read more »

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 »
The prerequisites for tomorrow’s EV and AV technologies
Sponsored by Scheugenpflug Scheugenpflug focuses on e-mobility and autonomous driving and, with its high-quality dispensing solutions, is accompanying an imminent turn of events in the growth field of mobility. Digitalization, e-mobility, autonomous driving, industry 4.0 and energy system transformation: Many of today’s megatrends would be unachievable without safe, reliable electronics. These electronics are becoming smaller,… Read more »
Tesla Cybertruck may be more aerodynamic than expected – Elon Musk says it could deliver a 0.30 Cd
Once they got over the smashed windows, the next thing many of the Cybertruck’s detractors focused on was its unconventional boxy shape. At first glance, the vehicle surely looks un-aerodynamic, which would be a serious drawback for any EV. However, as more information emerges, it turns out that the Cybertruck’s angular form might be almost… Read more »

New report: Cost and performance of batteries improving much faster than forecast
A new report from the Rocky Mountain Institute (via Forbes) finds that improvements in the cost and performance of batteries are quickly outpacing forecasts, due to massive investments in battery manufacturing and steady advances in technology. According to RMI’s Breakthrough Batteries Report, venture capital firms invested over $1.4 billion in battery tech in the first… Read more »
Argonne develops electrolyte for next-gen lithium battery with silicon anodes
Researchers at the DOE’s Argonne National Laboratory have developed a new electrolyte mixture and a simple additive that could have a place in the next generation of lithium-ion batteries that feature silicon anodes. The report findings were published in July in the journal ACS Applied Materials & Interfaces. Scientists have long seen the silicon anode… Read more »
EuroGroup’s new gluing technology promises to improve motor efficiency and reshape electric machine design
Groundbreaking glue: New results show as much as 44% core loss reductions for the same steel and lamination thickness. Many design decisions in the EV industry are still driven by range. Engineers remain focused on delivering system efficiency improvements, because it directly translates into delivering more range without increasing the size and cost of the… Read more »
A closer look at advances in power PCBs
In just the last few years there have been some major improvements in printed circuit board technology that are especially relevant to power electronics. Arguably the most important of the recent advances is the development of new board substrates that can withstand higher temperatures, along with metal cores for improved heat transfer, and the ability… Read more »
Cable sizing and selection for EV systems
Why Champlain Cable backs irradiation cross-linking for high-voltage EV cable insulation When you think of what makes up an EV, cables and wires probably aren’t the first components that come to mind. But these conduits comprise the electrical cardiovascular system that makes a vehicle function – from the battery to the motor and all the… Read more »
