Ford working with university on speeding EV charging

New cable cooling tech could reduce recharge time.

By Graeme Roberts

Ford and Purdue University researchers are working to develop a new, patent-pending charging station cable that “could” combine with in-development vehicle charging technology, to provide “seamless” EV re-charging.

What does the future hold for the US electric vehicles market?

The US Electric Vehicles (EV) market has established itself as one to watch. Despite China maintaining the number one spot, the US holds significant standing as one of the major EV markets, with GlobalData’s whitepaper identifying a strong growth trajectory within the forecast period. This report further analyzes the trends, market drivers, and government incentives set to influence and facilitate the market.   This report also looks beyond the US and touches on environmental concerns set to drive the EV market worldwide.   Want to find out more?

“Today, chargers are limited in how quickly they can charge an EV’s battery due to the danger of overheating. Charging faster requires more current to travel through the charging cable,” said Michael Degner, a senior technical manager at Ford R&D.

“The higher the current, the greater the amount of heat that has to be removed to keep the cable operational.”

Researchers are focusing on an alternative cooling method by designing a charging cable that can deliver an increased current. The cable uses liquid as an active cooling agent which can help extract more heat from the cable by changing form from liquid to vapour, the key difference between this and current liquid cooled technology.

This innovation could “one day” deliver significantly more power than today’s leading systems to recharge electric vehicles, making the potential of faster recharging times possible if vehicle charging and other technology enhancement is made in parallel.

Ultimately, this could eventually lead to re-charging EVs as quickly as conventional petrol station refuelling, Ford reckons.

“Electric vehicle charging time can vary widely, from 20 minutes at a station to hours on an athome charging station, and that can be a source of anxiety for people who are considering buying an electric vehicle,” said Issam Mudawar of Purdue University.

“My lab has come up with a solution for situations where the amounts of heat that are produced are beyond the capabilities of today’s technology.”

Mudawar said his lab intended to begin testing a prototype charging cable in the next two years to determine more specific charge speeds for certain EVs.
