NASA says the conductor-cooling technology developed for use on the ISS and future lunar and Martian missions will benefit electric vehicles. This technology should allow batteries to be charged at a faster rate than is currently possible.

A new complex cooling method based on the boiling of a refrigerant in a supercooled stream was developed by specialists from the US space agency to maintain the required temperature of electrics in space. However, it turned out that it can also be useful on Earth, as it will allow you to transmit a current of 1400 A for charging electric vehicles. This increases the speed of charging, because modern charging stations are capable of delivering up to 520A, with most generally only 150A.

The installation includes heating devices that stand along the walls of the flow channel, where the liquid heat carrier is supplied. The devices heat up and the temperature of the liquid in the channel increases, over time the liquid begins to boil. The boiling liquid creates small bubbles on the walls, moving away from the walls, constantly entraining the liquid from the inner region of the channel to the walls of the channel. This process efficiently transfers heat using both the low temperature of the liquid and the transition from liquid to vapor.

A cable can serve as a heating element in such a system, since the greater the current, the more heat is released when it passes through the conductor and the higher the likelihood of overheating of the components. Therefore, this NASA technology has the potential to provide fast charging without the problems of overheating parts of the chargers. The new technology can be used to deliver nearly 5 times the current of the fastest electric vehicle chargers on the market today, by removing up to 24.22kW of heat, the agency said.
