Abstract

Aiming at the core pain points in the experimental teaching of power battery recycling, such as high safety risk, difficult to understand the abstract mechanism, and high operation cost, this paper constructs and implements the three-level progressive teaching mode of "theory model practice" based on the self-developed "expansion characteristics disassembly risk classification model". The model transforms the complex electrochemical mechanical mechanism into visual teaching aids through theoretical visualization; Through model simulation, a virtual simulation platform embedded with risk early warning algorithm is developed to realize cost free trial and error in high-risk scenarios; Through the standardization of training, the model threshold is transformed into entity operation specification, and the virtual and real fusion is verified by the sensor system. The practice in the course of new energy vehicle power battery technology in Geely University shows that the teaching mode has significantly improved the students' safety risk prediction ability and the standardization of practice, the pass rate of the course assessment has increased from 75% to 92%, and the average score of the evaluation of safety risk prediction ability has increased by 31.5%, effectively getting rid of the dilemma of experimental teaching in high-risk areas. The virtual reality integration teaching mode formed in this paper is not only suitable for the field of power battery recycling, but also provides a replicable reform paradigm for other high-cost and high-risk engineering experimental teaching.
