Problems solved by technology

However, most of the existing battery pack shells have limited strength, and long-term use often causes deformation or cracking. Corrosion resistance and thermal conductivity also need to be improved. Therefore, it is necessary to design a new battery pack shell that can meet the strength requirements of the battery pack.

Abstract

The invention provides a battery pack shell. The battery pack shell comprises a battery pack box and a battery pack bottom plate which is opposite to the battery pack box, wherein the battery pack box is made of a magnesium aluminum alloy composite material, the magnesium aluminum alloy composite material is covered by a carbon fiber reinforced unsaturation resin and a glass fiber composite, and the battery pack bottom plate is made of a carbon fiber reinforced titanium-coated magnalium alloy composite. By virtue of the carbon fiber reinforced unsaturation resin, the glass fiber composite and the carbon fiber reinforced titanium-coated magnalium alloy composite, the battery pack shell has enough strength, also has a relatively good heat-conducting property and ultrahigh corrosion resistance, so that the property of a battery pack is improved.

Description

technical field [0001] The invention relates to the technical field of lithium ion batteries, in particular to a battery pack casing. Background technique [0002] As the concept of environmental protection is deeply rooted in the hearts of the people, pure electric vehicles, as a truly green and environmentally friendly vehicle, will surely become the future development trend of the automotive industry. For a long time, the development of electric vehicles has been limited by the two technical bottlenecks of high battery cost and short life. With the innovation and improvement of technology in recent years, battery technology has developed rapidly. Power batteries have also gradually developed from traditional lead-acid batteries to advanced green power batteries such as nickel-metal hydride batteries, lithium cobalt oxide, lithium manganese oxide, and lithium iron phosphate. However, although the performance of these new power lithium batteries has been greatly improved,...
