Description

technical field [0001] The invention relates to a multi-purpose functional fluid for new energy electric vehicles, a preparation method and application thereof, and belongs to the technical field of new energy electric vehicles. Background technique [0002] With the depletion of traditional energy sources, and the growing problem of greenhouse gas emissions and environmental pollution caused by traditional fossil energy sources, under the general trend of sustainable development, China has proposed specific goals for carbon peaking and carbon neutrality. The automobile industry has received the attention of various automobile manufacturers and the strong support of the government. Among many new energy electric vehicles, compared with traditional fuel vehicles, pure electric vehicles have eliminated exhaust emissions, continuously improved safety, and continuously extended mileage. They are increasingly recognized by the market and users, and are becoming China's new energy...

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
