Infrastructure remains a potent factor in EV adoption—the first questions asked by the EV-curious almost always have to do with the availability of charging. Tesla understood this from the beginning, and its Supercharger network has proven to be one of the company’s biggest competitive advantages. Now Porsche has taken a page from the Book of… Read more »

Is aviation the best application yet for hydrogen fuel cells?
Q&A with ZeroAvia CEO Passenger cars are well on their way to going electric, and the path to a big market share for heavy-duty EVs such as buses and delivery trucks is becoming clearer. However, aviation remains a new frontier for zero emissions. There are several new powertrain options, and none has yet proven itself… Read more »
With backing from VW and JB Straubel, QuantumScape stands out from the crowd of new EV stocks
Electromobility companies are going public at a pace that recalls the dot-com frenzy of the 1990s. Yes, history will probably repeat itself to a certain extent—some of these firms will go belly-up, but others will eventually grow into successful and influential players. One that seems particularly promising is QuantumScape, a California developer of solid-state lithium-metal… Read more »
Linear Labs raises $6 million to expand EV motor manufacturing in Texas
Electric motor manufacturer Linear Labs has raised an additional $6 million in funding to further develop manufacturing capabilities and grow its employee base. The new capital raise comes shortly after the announcement of a $68.9-million partnership with the City of Fort Worth, Texas, which includes an incentive package for Linear Labs’ plans to develop an… Read more »
Infineon to supply Danfoss with power semiconductors for EVs
Danfoss and Infineon Technologies have signed a multi-year volume supply agreement. Infineon will supply chipsets of IGBTs and diodes to Danfoss Silicon Power, to be used in power modules for inverters that control EV motors. “The market for electromobility is picking up noticeably, and the supply industry is getting ready for this,” said Claus Petersen,… Read more »

SiC vs GaN semiconductors for EV power converters: Tech Opinion
Just as engineers are starting to get used to the advantages (and quirks) of silicon carbide (SiC ) devices, another semiconductor material joins the fray: gallium nitride, or GaN. Though there are some superficial similarities between these two materials, and even some overlap in their areas of best use, it is my opinion that only… Read more »
Fraunhofer develops GaN power ICs with integrated sensors
Researchers from the Fraunhofer Institute have integrated current and temperature sensors, 600 V-class power transistors, freewheeling diodes, and gate drivers onto a gallium nitride (GaN)-based semiconductor chip. The new circuit measures 4 x 3 mm and enables high switching frequencies and a high power density, while providing fast and accurate condition monitoring, according to the… Read more »
