NASA Develops Revolutionary Technique Capable of Charging Electric Cars in Just Five Minutes

NASA Developed A Cooling System For Electronics That Would Be Used In Missions On The Moon And Mars. However, Scientists Decided To Allocate It To Electric Vehicle Charging.

NASA developed a cooling system for electronics in space that can be used for electric vehicle charging here on Earth. The model can boost the automotive market, allowing vehicles to be charged in just five minutes. To put this in perspective, the average time at major charging points for an electric car with a 40 kWh battery is 5 to 8 hours for a full charge on home networks.

NASA Technology Was Developed For Other Purposes

In a publication from the agency, it was explained that the Flow Boiling and Condensation Experiment (FBCE) project, heat transfer, can cool the cables that carry high currents, potentially enabling super-fast electric vehicle charging without the risk of overheating.

The initial goal was to allow the flow of two-phase fluid and heat transfer experiments to be conducted in a long-duration microgravity environment aboard the International Space Station.

According to NASA, the FCBE flow boiling module has heat-generating parts mounted along the walls of a flow channel where the coolant fluid is supplied in a liquid state. In this way, depending on the heating of these devices, the temperature of the liquid in the channel increases and the liquid adjacent to the walls begins to boil.

System Would Work In Missions On The Moon, Mars, And Beyond

After heating the liquid, small bubbles are formed on the walls that move away from the walls with high efficiency. According to researchers, this process transfers heat more effectively, taking advantage of the lower temperature of the fluid and also the phase change to vapor. This process is greatly improved when the liquid supplied to the channel is in a subcooled state.

The system was created to help provide nuclear fission power models for missions to the Moon, Mars, and beyond; vapor compression heat pumps to support lunar and Martian habitats; and systems to provide thermal control and advanced life support for spacecraft on board.

How Will NASA’s System Work For Electric Vehicle Charging?

The electric vehicle charging system has a cable that ends with a plug inserted into the vehicle’s charging port. Electrical current is delivered to the vehicle’s battery, which is responsible for powering the electric motor. 

The passage of current through a conductor results in a finite amount of heat generation, and the higher the current, the greater the heat generated.

Due to temperature limits, charging cables for common rapid charge systems, at 42 kW, require substantial conductors, making the cable very heavy and difficult to maneuver.

With NASA’s technology, the dielectric coolant liquid flows through the charging cable, capturing the heat generated by the current conductor. Subcooled flow boiling allows scientists to deliver 4.6 times more current compared to the fastest electric vehicle chargers currently available on the market, removing up to 14.22 kilowatts of heat.
