Abstract

The invention relates to a new energy vehicle power battery cooling liquid and a preparation method thereof. The cooling liquid is prepared by mixing and stirring according to the following component proportions: ethylene glycol 25%-95%; azole compounds 0.5%-3%; Corrosion agent 0.2%-2%; the balance is deionized water; compared with the cooling liquid of the prior art, the new energy vehicle power battery cooling liquid provided by the present invention does not contain inorganic salts, and is compounded with an organic special effect corrosion inhibitor, so that the The power battery cooling liquid of the present invention has excellent metal anti-corrosion effect, and has long-term and extremely low electrical conductivity, and meets the cooling, anti-corrosion, insulation, long-term and other requirements of the cooling liquid for the power battery cooling system of new energy vehicles.

Description

technical field [0001] The invention belongs to the technical field of vehicle power battery cooling fluid, and in particular relates to a new energy vehicle power battery cooling fluid and a preparation method thereof. Background technique [0002] New energy vehicles mainly rely on the drive motor to convert the electrical energy stored in the power battery into the kinetic energy of the wheels to drive the vehicle to run. The cooling performance of the power battery directly affects the efficiency of the battery, as well as battery life and use safety. At present, the cooling of power batteries is mainly divided into two categories: air cooling and liquid cooling: air cooling is divided into natural convection, natural wind forced convection and air conditioning cold air forced convection; liquid cooling is divided into cooling liquid cooling and refrigerant cooling. [0003] Existing coolants mostly use inorganic salt formulations, or organic acid / inorganic salt mixed fo...
