[Original by Dongchedi Industry] According to foreign media reports, recently, many advanced technologies developed by NASA for space missions can be used on the earth. Among them, the latest "temperature control technology" can improve the charging power level by achieving more efficient heat transfer capabilities and enable electric vehicles to charge faster.

NASA cooling technology charging peak power 3750 kW

It is reported that many NASA space missions, complex systems that must maintain a specific temperature to operate, such as nuclear fission power systems and steam compression heat pumps that will be used to support the Moon and Mars , Mars missions, require advanced heat transfer capabilities. A research team sponsored by

NASA is developing a new technology: Flow Boiling and Condensation Experiment (FBCE), which “will not only achieve orders of magnitude improvements in heat transfer, allowing these systems to maintain proper temperatures in space, but will also significantly reduce the size and weight of cooling equipment.” It is of great practical significance for high-power DC charging stations.

It is understood that as early as August 2021, FBCE technology was delivered to International Space Station , and began to provide microgravity flow boiling data in early 2022. Recently, the R&D team of will apply the principles of FBCE to the charging process of electric vehicles .

This new technology of non-conductive liquid coolant is pumped through a charging cable, where it captures the heat generated by the current-carrying conductor, and the supercooled flow boils allow the device to remove heat up to 24.22 kW.

The team said that its charging system can provide up to 2400 amperes. This is an order of magnitude higher than the current charging device with 350 kW or 400 kW power that passenger car CCS chargers can provide. If the charging system can be promoted in the commercial field, its importance will be at the same level as the MW charging system.

It is reported that the megawatt charging system (MCS) is designed to provide a maximum current of 3000 amperes at voltages up to 1250 volts, and its potential charging peak power is about 3750 kilowatts. And in a demonstration in June 2022, the output power of the MCS prototype test charging device exceeded 1 megawatt.
