Abstract: In the teaching practice of the new energy vehicle course, due to the high purchase cost of equipment and models and the limited on-site resources, students have to share resources, which limits independent operation and exploration and affects the learning efficiency. Taking the Tesla battery electric vehicle as an example, this article first conducts 3D modeling using the MAYA software, and then develops a virtual teaching system based on the Unity 3D software, which can complete virtual experiments such as the display design of the vehicle structure, the composition of the battery structure, the series and parallel connection of batteries, and the application of power selection. The traditional planar teaching has been transformed into a three-dimensional teaching that is not restricted by time and place, enhancing the interaction of scenarios. It is expected that through this system, students can obtain a real, immersive and exploratory learning experience in a virtual environment.

摘要： 新能源汽车课程的教学实践中，因设备与模型购置成本高、现场资源有限，导致学生 需共享资源，限制了独立操作与探索，影响学习效率。文章以特斯拉纯电动汽车为例，先利 用 MAYA 软件进行三维建模，再基于 Unity 3D 软件开发了可完成整车结构展示设计、电池构 造组成、电池串并联及动力选择应用虚拟实验等内容的虚拟教学系统，实现了由传统平面式 教学转变为不受时间、地点限制的立体式教学，增强情景交互。期望通过这个系统使学生在 虚拟环境中获得真实地、沉浸式、探索式学习体验。
