Core Technology and Performance Breakthrough
The equipment adopts EHC segmented impact heat transfer technology and ACC dynamic refrigeration control technology, which improves the response speed of direct cooling by 30% at a high temperature of 300 ℃. Through frequency conversion technology and heat recovery design, it saves 70% -95% energy compared to traditional liquid nitrogen refrigeration. Its constant power output control technology can accurately simulate the dynamic thermal load of battery packs in scenarios such as fast charging and high rate discharge, and with the help of multiple pressure and flow sensors, achieve multi-dimensional coordination of temperature control, pressure control, and flow control. The fully enclosed system uses a self-lubricating magnetic coupling circulation pump to eliminate medium oxidation and pollution, significantly extending the service life of cooling media such as ethylene glycol aqueous solution, while reducing maintenance costs.
