NASA space technology can charge your electric car in just 5 minutes

Washington, October 7 (IANS) A NASA technology, designed with researchers at Purdue University for future space missions, can charge an electric car in just five minutes on Earth, potentially paving the way for increased adoption of electric cars.

Purdue University’s charging cable can deliver 2,400 amps, which is well beyond the 1,400 amps needed to cut the time it takes to charge an electric car to five minutes, NASA said in a statement.

The team, sponsored by NASA’s Biological and Physical Sciences Division and led by Issam Mudawar, developed the Flow Boiling and Condensation Experiment (FBCE) to enable two-phase fluid flow experiments and heat transfer, to be conducted in the long-duration microgravity environment on the International Space Station.

This new “subcooled flux boiling” technique results in significantly improved heat transfer efficiency compared to other approaches and could be used to control temperatures of future systems in space.

This technology also has applications on Earth – in particular, it could make owning an electric car more attractive.

Currently, electric vehicle charging times vary widely, from 20 minutes at a station along a road to hours of use at a home charging station.

Long charging times and charger location are both cited as major concerns for people considering electric vehicle ownership.

According to the researchers, reducing electric vehicle charging time to five minutes (an industry goal) will require charging systems to deliver current at 1,400 amps.

Recently, Mudawar’s team applied the principles of “subcooled flow boiling” learned from NASA’s FBCE experiments to the charging process of electric vehicles.

Subcooled flow boiling enables the Mudawar team to deliver 4.6 times the current of the fastest electric vehicle chargers available on the market today by removing up to 24.22 kilowatts of heat.

“The application of this new technology has resulted in an unprecedented reduction in the time required to charge a vehicle and could remove one of the main barriers to global adoption of electric vehicles,” the researchers said.
