Following the release of the FF91 pre-production car assembly video in early December, recently Faraday Future (hereinafter referred to as "FF"), an electric car company on the other side of the Pacific, announced that it will work with supplier Mivolt on a full-immersion cooperation on battery cooling systems. Mivolt will provide FF with advanced dielectric cooling materials to support FF’s patented fully immersed battery liquid cooling system, which includes an integrated battery pack design with a safety architecture.
Recently, in a live webcast seminar between FF and Mivolt with the theme "Exploring the Future", the two parties discussed the fully immersed cooling electric vehicle battery technology. FF Senior Chief Thermal Engineer Nicolas Bel explains the advantages of the FF fully-immersed battery cooling system using Mivolt liquid as coolant.
For example, Mivolt coolant, as a non-conductive liquid, can ensure uniform temperature of all components of the battery pack; the coolant surrounds all batteries, current collectors and control units, stabilizing the relationship between modules and battery strings. temperature, allowing the battery pack to better respond to the high demands of the vehicle; electronic components and their connections are immersed in liquid, eliminating potential risks of corrosion, etc.
Regarding the principle of the fully immersed battery cooling system, FF’s previous explanation is that FF’s vehicle manufacturing basis is the variable electric drive chassis architecture (VPA) developed based on FF’s concept, and the battery pack is It is a key system of VPA, and if you want to achieve battery life and other performance safely and effectively, you need a complex system to support it, which is closely related to the thermal management of the battery pack.
Therefore, in the process of designing VPA, FF proposed the solution of "full immersion system", that is, all main battery components are immersed in the coolant, and obtained the patent for this solution in 2015. patent. At that time, FF's requirements for coolant were: "The coolant must be compatible with the battery, non-flammable, low viscosity, and relatively cheap."
According to FF, FF is currently working on improving vehicle performance , reliability, safety and new user-centered concepts are integrated into the overall design of the vehicle. For example, FF91 is equipped with a 130kWh battery, with a cruising range of more than 300 miles (483 kilometers), and a charging range of more than 500 miles (805 kilometers) per hour. The home charging pile planned to be included with the car will operate at 240V voltage. , it only takes less than 4.5 hours to charge the car from 50% to full. FF attributes the realization of these functions to its fully immersed cooling system that it has been gradually improving over the past five years.
According to the mass production plan disclosed by FF, so far, dozens of Faraday Future’s engineering prototype vehicles used for testing have rolled off the production line, and more than ten quasi-production vehicles have rolled off the production line. With the development of business, , FF91 verification testing has also reached the final stage.
In October this year, FF also reported that the company received investment from its "old owner" American commercial bank Birch Lake and co-investor ATW Partners, and completed its expansion and expansion based on the 2019 senior bridge financing loan program. The extended, revised bridge financing facility includes a new senior secured loan of up to $45 million.
The strong assistance from the two financial institutions bought more time for FF’s equity financing. It is understood that FF is currently promoting debt and equity financing in the Middle East, Europe and the Asia-Pacific region, and many investors have clearly expressed their investment intentions. If all goes well, FF91 is expected to be launched as soon as next year, and the newly released FF?81 Preparations for the development of electric vehicles, future models and next-generation core technologies will be carried out after the launch of FF?91.
