Ford Motor Company researchers are working with Purdue university to invent a method for charging stations to deliver significantly more power than today’s best systems. The new technology could bring charging times down from 20 minutes or more to get an 80% recharge to the time it usually takes to fill a gas tank. The Ford /Purdue system uses a liquid to gas cooling system that appears to dissipate substantially more heat  as opposed to the liquid cooling systems used for todays 350 kW chargers. “Today, chargers are limited in how quickly they can charge an EV’s battery due to the danger of overheating,” said Michael Degner, senior technical leader, Ford Research and Advanced Engineering. “Charging faster requires more current to travel through the charging cable,” said Degner. “The higher the current, the greater the amount of heat that has to be removed to keep the cable operational. The cable uses liquid as an active cooling agent, which can help extract more heat from the cable by changing phase from liquid to vapor,” Ford explained in a statement, “the key difference between this and current liquid-cooled technology on the market.” The system will go through a two year test program to determine if it will be put into production.
