South Korean battery supplier SK On is looking at a different type of cooling method for electric vehicle battery packs. Last week, SK On put the focus on immersion cooling at InterBattery 2025, a South Korean battery trade show. Instead of circulating coolant or air around battery cells and modules, this method involves immersing them in a... Future EVs might keep battery packs cool in this different way

"Real-world validation testing" completed on inboard-motor setup Aptera switched to the layout, instead of in-wheel motors, for its future solar EV Per-mile energy consumption remains in line with previous layout Aptera last week announced that it had completed the first round of "real-world validation testing" of its solar-assisted three-wheeled... 
Stellantis is experimenting with multi-speed transmissions to improve the efficiency of electric vehicles, a recently surfaced patent filing indicates. Published by the United States Patent and Trademark Office (USPTO) Feb. 27, 2025, but originally filed by the automaker in 2023, the patent application deals specifically with adding a second... 
Rivian is looking to patent wheel covers with active aerodynamic elements to further improve the efficiency of its electric vehicles. Smooth wheel covers—like the ones available on the updated 2025 Rivian R1S and R1T—can help reduce aerodynamic drag, but they're generally fixed in place, and thus not optimized for all scenarios. In its...
