Seoul Semiconductor says its 12 V High Voltage (HV) opto-semiconductor technology has entered mass production with four unnamed automotive brands across the Americas, Europe and Asia. The company plans to deploy the technology in 10 vehicle models by year-end. The technology addresses a voltage mismatch problem that’s grown more acute in EVs and hybrids. Conventional… Read more »
Kautex Textron has secured an agreement to supply its Pentatonic battery enclosure system to an unnamed automotive OEM for a multi-vehicle hybrid platform. North American production is scheduled to begin in 2028. The agreement includes the full battery enclosure system—top cover, bottom tray and thermal management—which is manufactured using what Kautex describes as a highly… Read more »
Wolfspeed has introduced its fifth-generation silicon carbide MOSFET technology for 1,200 V and 750 V automotive and industrial applications. The company says these new chips offer the lowest specific on-resistance (RSP) available in a 5×5 mm SiC footprint. The 1,200 V QEM50120-025D10 achieves a chip-level RSP of 3.4 mΩ·cm² at 175° C. The 750 V… Read more »
LibertyStream Infrastructure Partners has completed its first tonne delivery of lithium carbonate to a US industrial customer from its direct lithium extraction (DLE) unit and refining facility at Select Water Solutions’ site in Howard County, Texas—moving from on-site production into actual commercial delivery. The shipment fulfills LibertyStream’s previously announced first US order, and was produced… Read more »
Optimus Energy Solutions has acquired an EV charging network in South Carolina. Originally developed through a Duke Energy pilot program, the network includes 52 DC fast chargers at 26 locations throughout the state, many of them located along major travel corridors. As Duke Energy’s pilot program reached its planned conclusion, Optimus Energy Solutions assumed ownership… Read more »
Danfoss Scotland, part of hydraulics and electric powertrain systems supplier Danfoss Power Solutions, has announced the results of its Dextreme Max system validation in a 30-ton battery-electric excavator. The company demonstrated that its Dextreme digital hydraulic architecture reduced excavator power consumption by 35% across a representative duty-cycle mix, corresponding to 53% longer runtime on a… Read more »
In time for the summer travel season, financial giant Chase has announced that its Freedom and Freedom Flex cardmembers can earn 5% cash back on gas, EV charging, public transit and selected live entertainment purchases. Hurrah! Yet another perk of driving electric. But before we start planning a transcontinental road trip, let’s look at the… Read more »
Lithium-ion has been the world’s workhorse battery technology for a couple of decades now. There are several newer technologies that are at or near the deployment stage. The Chinese firm CATL, the world’s largest battery manufacturer, has already deployed sodium-ion battery packs in EVs from automakers including GAC and Changan. Looking ahead however, CATL appears… Read more »
Bidirectional EV charging, which supports vehicle-to-home (V2H) and vehicle-to-grid (V2G) functions, is gradually moving from the pilot stage to commercial availability. EVs from automakers including Ford and Kia now offer bidirectional features. GM’s Chevrolet Equinox EV, GMC Sierra EV and Cadillac Lyriq now offer bidirectional capability, and the automaker recently released a primer on how… Read more »
Engineering specialist IAV and semiconductor firm Nexperia have developed a lab-validated concept called ONE Inverter that uses software-defined control and bidirectional GaN switching to manage individual battery sections rather than treating a pack as a single unit. In conventional series-string battery architectures, every cell must carry the same current, meaning the pack’s effective capacity is… Read more »
