新能源汽车电气故障诊断技术在职业教育教学中的实施与创新

摘要

随着新能源汽车产业的迅猛发展，职业院校对新能源汽车电气系统故障诊断的教学需求日益增长。本文深入分析了职业院校新能源汽车电气系统教学的现状，包括学生学情特点以及教学过程中的硬件设备不足、企业案例更新滞后、评价体系单一等痛点。在此基础上，提出了理实一体化教学模式创新、智慧课堂技术赋能、安全规范与职业素养培养等教学实践策略，并通过吉利EV450高压互锁故障检修案例进行具体分析，旨在为职业院校新能源汽车电气系统故障诊断教学提供有益的参考与借鉴，提升教学质量，培养符合行业需求的高素质技术技能人才。

Abstract

With the rapid development of the new energy vehicle (NEV) industry, vocational colleges have an increasing demand for teaching on NEV electrical system fault diagnosis. This article provides an in-depth analysis of the current situation of NEV electrical system teaching in vocational colleges, including the characteristics of student learning, as well as pain points such as insufficient hardware equipment, lagging enterprise case updates, and a single evaluation system in the teaching process. Based on this, it proposes teaching practice strategies such as the integration of theory and practice teaching mode innovation, smart classroom technology empowerment, and safety norms and professional ethics cultivation. A specific analysis is conducted through the case of Geely EV450 high-voltage interlock fault maintenance, aiming to provide useful reference and lessons for vocational colleges' NEV electrical system fault diagnosis teaching, improve teaching quality, and cultivate high-quality technical and skilled talents that meet industry needs.
