Solid-state electrolytes are the talk of the town these days. California-based PATHION has been working to commercialize solid electrolytes since its founding in 2012, building on its exclusive license from Los Alamos National Laboratories for a promising material called Lithium-Rich Anti-Perovskite (LiRAP). At the recent Materials Research Conference, PATHION presented two new superionic solid-state electrolytes built upon… Read more »

ZF unveils electric transaxle system for tractors with integrated power electronics
ZF has announced its eTERRADRIVE, a modular and highly integrated electric transaxle system designed for battery-electric vehicle architectures in agricultural tractors ranging from 60 to 100 kW. This system combines traction, mechanical power take-offs, working hydraulics and rear lift within a single compact unit, aiming to facilitate integration and flexibility across a variety of tractor… Read more »
Video: Schaeffler’s all-solid-state battery module and other eMobility innovations
At this year’s Battery Show in Detroit, Charged spoke with four of Schaeffler’s subject-matter experts to explore the company’s innovations in electrification and energy storage. The discussion began with Rashid Farahati, Vice President of the Corporate Competence Center for the Americas. Farahati explained that while solid-state batteries promise higher energy density, safety and faster charging,… Read more »
Ideal Power increases B-TRAN bidirectional semiconductor power rating, targeting EV contactor applications
Ideal Power has the power rating of its discrete B-TRAN bidirectional semiconductor power switch from 50 A to 75 A. The company says that the higher rating is supported by extensive internal and third-party testing, and no design or packaging changes were required. While the official rating is now 75 A, the device has been… Read more »
Taiga unveils electric watercraft lineup with new model and vehicle-to-grid power
Taiga Motors, a Canadian startup that bills itself as a leader in “electrification beyond the road,” has unveiled its next-generation Orca line of electric watercraft. The new Orca WX3 delivers a versatile crossover platform and up to two hours of operating time on the water. The WX3’s hydrodynamically engineered extended hull provides strong stability, whether… Read more »
Mercedes-Benz EQS with solid-state battery makes 749-mile test drive on a single charge
Solid-state EV batteries are making the transition from the laboratory to real-world testing—this week we’ve seen announcements from QuantumScape, Rimac, and now Mercedes-Benz, which demonstrated its solid-state technology on a test drive from Stuttgart, Germany to Malmö, Sweden. A “lightly modified” Mercedes EQS test vehicle equipped with a lithium-metal solid-state battery completed the 1,205-kilometer (749-mile)… Read more »

Rimac Technology has presented new EV battery platforms, ultra-compact powertrains, and next-generation control electronics at IAA Mobility, detailing platforms developed through collaborations with ProLogium, Mitsubishi Chemical Group and Kautex Textron. These solutions are designed for large-scale production and production-ready, according to Rimac, aiming for integration in hundreds of thousands of vehicles in the near future…. Read more »
Advanced cooling methods for power electronics
One of the primary issues the power electronics engineer must address is the removal of waste heat—the well-known Arrhenius equation from chemistry/physics tells us that the operational life of any given electronic component will roughly double for every 10-11° C drop in its temperature. Power electronics devices on EVs are also under considerable pressure to… Read more »
Stellantis and Factorial Energy validate solid-state automotive-size battery cells
Stellantis and Factorial Energy have announced the successful validation of Factorial’s automotive-size FEST (Factorial Electrolyte System Technology) solid-state battery cells. Solid-state batteries could offer higher energy density and faster charging than today’s lithium-ion batteries. The validated 77 Ah FEST cells demonstrated specific energy of 375 Wh/kg over 600 cycles, progressing towards automotive qualification. The cells… Read more »
