基于安全、轻量化、可靠性多目标的新能源汽车电池包壳体开发

电池包作为新能源汽车的动力源，是新能源汽车最重要的部件之一，而电池包壳体对电池包乃至整车起重要保护作用，是新能源汽车的关键部件。电池包壳体质量占整车的2%～6%，电池包壳体对汽车轻量化同样起到重要作用。基于全球汽车产业的节能减排发展目标，从安全性、轻量化、可靠性3个角度出发，论述了新能源汽车电池包壳体开发的行业发展现状，展望其未来的发展趋势，同时针对这一领域存在的共性关键技术问题进行了讨论。

Development of New Energy Vehicle Battery Cases Based on Safety, Lightweighting and Reliability

The battery pack, as the power source for new energy vehicles, is one of the most important components. The battery shell not only plays a vital role in protecting the battery package, but also contributes significantly to the vehicle''s lightweight design, accounting for 2% to 6% of the total weight of the vehicle. Based on the global automotive industry''s development goals for energy conservation and emission reduction, this paper discusses the development status quo of the new energy vehicle battery case industry, focusing on three aspects of safety, lightweighting and reliability. The common key technical challenges in this field are discussed, and the future development trends are proposed.
