A joint project between Purdue University and Ford may have developed five-minute charging for electric vehicles. Researchers said their new type of charging cable is capable of carrying a much higher load without overheating, which has been the barrier to faster charging than the 30 minutes offered by Level 3 chargers.

Purdue’s cables use liquid-to-vapor cooling to carry the higher load without getting too hot. Researchers said so far, the cables’ use has only been in simulators, but  they’ll be tested on vehicles in the next two years.
