NASA technology cools the electric vehicle cable to produce much more powerful charging systems than current ones.

It can take 10 hours to fully charge an electric vehicle battery at home, but now NASA has given details of a cooling system that could reduce the full charge time to just five minutes.

NASA technology could be a change of course for the electric vehicle sectorBecause it would remove one of their biggest hurdles to adoption: That five-minute charge would put electric vehicles on the same level as the time it takes to fill a car’s gas tank.

The answer to charging in five minutes could be found in the «Flow Boiling Condensation Experiment (FBCE)“, a project that NASA’s Division of Biological and Physical Sciences is funding to develop at Purdue University and that focuses on refrigerants in the charging cable between the EV inlet and the battery.

The Purdue researchers demonstrated a technique called “subcooled flow boiling» that improves the efficiency of heat transfer, which could help EVs on Earth, but it is primarily intended for the International Space Station.

When available, NASA technology could provide the temperature controls those charging systems would require.

As NASA explains, a five-minute charge requires a charging system that provides a current of 1,400 A. But, as Purdue points out, the Supercharger V3 Tesla, which is the spearhead of current electric vehicle chargers, does not exceed 600 amps. Last year’s Purdue prototype demonstrated 2,400 amps.

Hence the eventual need for a cooling system that exceeds current capabilities and can withstand 1,400 A. Using NASA’s FBCE, Purdue researchers, led by Dr. Issam Mudawar, pumped electrically nonconductive coolant into through a charging cable to capture heat from the current-carrying conductor.

Subcooled flow boiling allows the Mudawar team to supply 4.6 times the current of the fastest electric vehicle chargers currently on the market, removing up to 24.22 kilowatts of heat.

The application of this new technology has led to an unprecedented reduction in the time required to charge a vehicle and may remove one of the main barriers to the global adoption of electric vehicles.


Faster charging times should drive greater adoption of electric vehicles, which are part of the global response to achieving net zero carbon emissions.
