NASA's conductor cooling technology, developed for use at the International Space Station and for future Moon and Martian missions, will be used by Earth's electric vehicles, which will allow the charging of batteries at a much higher rate than is possible at existing charging stations.
The American Space Agency reported that an integrated cooling method based on "" had been developed by NASA specialists to maintain an adequate temperature of electricians in space, but it could also be useful on Earth because it would allow the current to be transferred by 1,400 amperes to charge electric vehicles. By comparison, modern charging stations could produce up to 520 amperes and, in most cases, only 150 A.
The experimental installation includes heating devices installed along the walls of the leaking canal to which the liquid heater is fed. As these devices are heated, the temperature of the liquid in the canal increases and the liquid adjacent to the walls starts to boil over over time. The boiling liquid forms small bubbles on the walls that quickly move away from the walls, constantly drawing the liquid from the inner part of the canal to the walls of the canal. This process effectively transmits heat, using both a lower liquid temperature and a phase shift from liquid to vapour. The process is also greatly improved if the liquid is applied in a cooled state.
The heater can be a cable because the greater the current, the greater the heat during the conductor, the more likely it is to overheat the components. Accordingly, the NASA technology to effectively cool high charge cables has the potential to provide a super-fast charge without the risk of overheating the parts of the chargers. A potential new system can be used for "", declared in NASA.

The U.S. government plans to install 500,000 electric vehicle charging stations across the country by 2030, increasing its investment.
