Problems solved by technology

[0005] 1. For OEMs and users, there are many oil use points that need to be paid attention to, and there are risks such as misuse and mixed use;
[0006] 2. For the electric vehicle itself, there is a lack of a dedicated oil solution, and the pertinence is not strong, and the performance is naturally mixed; there are certain risks and safety hazards in the water-ethylene glycol system battery management fluid. This problem is solved in the inventor's invention Patent: A dielectric coolant for new energy electric vehicles and its preparation method (Application No.: 202110545642.X) is described in detail, and will not be repeated here
[0007] 3. Requirements for the innovation of cooling methods: at this stage, the cooling method of indirect cooling is mostly used, but this method has the disadvantages of slow heat dissipation and uneven heat distribution. The contact surface between the cooling system and the battery cools quickly, but the inside of the battery The cooling speed is slow, so the cooling method similar to the direct cooling of the internal combustion engine has attracted more and more attention
However, the water-glycol coolant system is not suitable for direct cooling cooling systems due to the risk of electrical conductivity
