在本文中，提出了一种新的建模框架来估计系统级性能的电动汽车利用结构电池复合材料。电气和机械性能源自组件的材料数据、器械设计和连接/铺层方案。多功能的知识，我。e.结构电池复合物的电和机械性能允许估计任何已知驱动循环的电动车辆驱动范围。该框架用于评估结构电池引入现有电动汽车（EV）对驱动范围的影响。对Tesla Model S和BMW i3进行的比较研究表明，在保持续驶里程性能的同时，具有引人注目的车辆减重潜力。或者，如果通过引入结构电池来保持车辆重量，则轻型电动汽车的行驶里程将增加70%。
In this paper, a novel modelling framework to estimate system level performance of electric vehicles utilizing a structural battery composite material is presented. Electrical and mechanical properties are derived from material data of the constituents, device design and connection/layup schemes. Knowledge of the multifunctional, i. e. electrical and mechanical, performance of the structural battery composite allows for estimation of the electric vehicle drive range for any known drive cycle. The framework is used to evaluate effect on drive range from the introduction of structural batteries into existing electric vehicles (EVs). Comparative studies performed for Tesla model S and BMW i3 demonstrate a compelling vehicle weight saving potential with maintained drive range performance. Alternatively, if vehicle weight is to be maintained from the introduction of structural batteries the resulting drive range for lightweight EVs will be increased by 70%.
