动力电池检测评估体系发展方向和趋势

Development direction and trend of power battery detection and evaluation system

简述了新能源汽车动力电池发展背景,从系统构成和电极材料分类介绍现有动力电池产品;汇总国际、国内新能源汽车动力电池检测主流标准,标准主要包含产品电性能、安全性能等测试项目;国内标准和国际标准发展方向趋于一致,但细节差异较大;分析新能源汽车动力电池检测体系实施现状,国内、国际以及企业标准融合使用验证项目产品成为一种主流方式;基于产品全生命周期低碳化,动力电池作为重要电能载体,未来动力电池检测评估体系构建将更加完善。

The development background of new energy vehicle power battery is reviewed,and the existing power battery products are introduced from the aspects of system composition and electrode materials.The international and domestic mainstream standards for testing new energy vehicle power batteries are summarized,which mainly include testing items such as electrical performance and safety performance of products.Domestic standards and international standards tend to develop in the same direction,but the details differ greatly.Analysis of new energy vehicle power battery testing system implementation status,domestic,international and enterprise standards integration use validation project products become a mainstream way.Based on the development background of"carbon neutral"society and the use perspective of the whole life cycle of products,the construction of power battery detection and evaluation system will be more perfect in the future.
