Purdue University engineers have invented a new, patent-pending charging station cable that would fully recharge certain electric vehicles in under five minutes – about the same amount of time it takes to fill up a gas tank.
Today, chargers are limited in how quickly they can charge an EV’s battery due to the danger of overheating. To charge an EV faster, a higher current needs to travel through the charging cable. The higher the current, the greater amount of heat that must be removed to keep the charging cable operational. The cooling systems that chargers currently use remove only so much heat.
Using an alternative cooling method, Purdue researchers designed a charging cable that can deliver a current 4.6 times that of the fastest available EV chargers on the market today by removing up to 24.22 kilowatts of heat. The project was funded by a research and development alliance between Ford Motor Co. and Purdue.
