Shell unveils EV concept with battery tech that could slash charging times

Shell unveiled its Triple 10 Challenge Concept, a small electric concept car designed as a city-scale EV testbed for a new approach to managing battery heat. The company says the design could cut charging times and reduce its carbon footprint by half compared with current European EVs, while targeting 6.2 miles per kilowatt-hour of efficiency. Shell’s battery approach replaces standard indirect battery cooling with a nonconductive dielectric fluid that can surround battery cells directly, improving heat removal during fast charging when temperatures typically force charging speeds to taper. Shell claims the concept can charge from 10% to 80% in under 10 minutes on a 175-kilowatt charger, adding 15 miles of range per minute. Shell says it is not signaling plans to build a car, but instead wants to demonstrate cooling technology for automakers. Some commenters questioned fluid durability and crash fire behavior.
