White paper calls for new reliability testing approach for EV BMS
The Global Electronics Association has released a new white paper examining reliability challenges in battery management systems as electric vehicle (EV) architectures move toward higher voltages, continuous operation and longer service lives. The paper argues that traditional qualification methods may not fully capture failures that develop gradually under real-world operating conditions. These can include moisture…
Coesia to showcase integrated battery manufacturing at The Battery Show
Coesia will showcase a range of manufacturing technologies at The Battery Show North America, designed to support higher-volume lithium-ion battery production, with a focus on improving process control, automation, and scalability for electric vehicle (EV) cell manufacturing. The show takes place from October 13 to 15, 2026, in Detroit, MI (Booth 4800). A major focus…
ROHM SiC MOSFETs selected for BMW Neue Klasse EV powertrain
ROHM’s silicon carbide (SiC) MOSFETs are being integrated into BMW’s Neue Klasse electric powertrain architecture as part of the automaker’s sixth-generation electric vehicle (EV) technology. The SiC devices will support power conversion within the electric drivetrain, where reducing switching and conduction losses can improve overall powertrain efficiency. The technology is also intended to support the…
Researchers improve anode-free lithium metal battery stability
Researchers patterned copper current collectors with nanoscale structures and an MXene coating to suppress lithium dendrite growth without adding excess lithium. A research team at the Korea Advanced Institute of Science and Technology (KAIST) has developed a method for extending the cycle life of anode-free lithium metal batteries by applying ultrafine fabrication processes from semiconductor…
Semi-dry braking architecture reduces residual brake drag
AUMOVIO has developed a semi-dry brake system that combines electromechanical braking with a conventional hydraulic front axle, using active brake-pad clearance to reduce residual drag in electric vehicles (EVs). The system uses a near-production electromechanical brake on the rear axle. Instead of relying on hydraulic pressure, an electric motor actuates the rear brake caliper, eliminating…
