Description
technical field [0001] The invention relates to the technical field of new energy vehicles, in particular to a high-strength and lightweight new energy vehicle battery pack case. Background technique [0002] At present, in the application of battery packs (also known as "battery power systems"), especially in the field of new energy electric vehicles, battery packs are required to have high specific energy, high safety factor and long service life; The battery pack with high energy density will generate a certain amount of heat during operation. If the heat cannot be taken away in time, it will cause great harm to the life and safety performance of the battery pack. Therefore, it is necessary to conduct thermal management on the battery pack. For example, it is necessary to design a battery pack that keeps the battery at a suitable temperature and has a light weight, so as to meet the requirements of high energy density of the whole battery pack and light weight of the whol...
