Abstract

The invention discloses a cooling liquid for a power battery of a new energy automobile. The cooling liquid comprises the following substances in parts by mass: 50-60 parts of ethylene glycol; 40 to 50 parts of EDI purified water; 1 to 2 parts of ethanolamine phosphate; 0.22 part to 0.45 part of sodium borate; 0.38 to 0.4 part of tris (hydroxymethyl) aminomethane; the invention also discloses a preparation method of the cooling liquid. The metal corrosion inhibitor has the advantages of wide temperature range and slow metal corrosion.

Description

technical field [0001] The invention relates to the technical field of power batteries, in particular to a new energy vehicle power battery cooling liquid, a preparation method and an application thereof. Background technique [0002] Due to the need for high-power charging and discharging, the power battery generates a lot of heat during use. In order to ensure the stable performance of the power battery and ensure its service life, the power battery needs to be cooled. The current heat dissipation methods of electric vehicles are often divided into liquid cooling, phase change material cooling and air cooling according to the different cooling methods of the battery. Liquid cooling is a more commonly used liquid cooling method. Direct cooling is to immerse the battery directly in the cooling liquid. In practical applications, mineral oil can be used as a direct contact heat transfer medium, using its properties as an insulating dielectric to avoid short circuits in the bat...
