Far Ahead Of The World's Fast Charging Pile! NASA Cooling Technology Charges A Peak Power Of 3750kW
Oct 12, 2023
Fast charging of electric vehicles has always been a difficult point in the demand for new energy vehicles, and innovative cooling methods are expected to greatly increase charging power.
Recently, it has been reported that many advanced technologies developed by NASA for space missions can already be applied to Earth.
Currently, "temperature control technology" can increase charging power levels by enabling more efficient heat transfer capabilities, enabling electric vehicles to charge faster.
Many NASA space missions, complex systems that must maintain specific temperatures to operate, such as nuclear fission power systems and vapor compression heat pumps that will be used to support lunar and Mars missions, require advanced heat transfer capabilities.
A NASA-sponsored research team is developing a new technology, the Flow Boiling and Condensation Experiment (FBCE), that will drastically reduce the size and weight of cooling equipment, which is very practical for high-power DC charging stations.
The FBCE technology was delivered to the ISS in August 2021 and began providing microgravity flow boiling data in early 2022. Recently, the R&D team will apply the principle of FBCE to the charging process of electric vehicles.
The new technology's 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 boiling enables the device to remove up to 24.22kW of heat.
The team says its charging system can deliver up to 2400A. This is an order of magnitude higher than the 350kW or 400kW charging units that can be provided by current passenger car CCS chargers. If the charging system can be promoted in the commercial field, it will be at the same level of importance as the megawatt charging system.
The megawatt charging system (MCS) is designed to deliver a maximum current of 3000 amperes at voltages up to 1250V, with a potential charging peak power of about 3750kW (3.75MW). In a demonstration in June 2022, the output power of the MCS prototype test charging device exceeded 1 MW.
