Virtual Reality for Safe Training in Electric Vehicle Maintenance: A Simulation-Based Learning Environment

Introduction: The rapid expansion of electric vehicles (EVs) has introduced new technical challenges for professionals involved in vehicle inspection, maintenance, and repair. High-voltage systems require specific safety procedures to prevent electrocution risks during interventions. Traditional training approaches based on real vehicles are often limited by safety concerns, equipment availability, and logistical constraints, particularly when training large groups of professionals. Virtual Reality (VR) provides an immersive and controlled environment where complex procedures can be practiced without physical risk. This study explores the implementation of a VR-based training system designed to teach EV safety procedures in a professional learning context.

Methods: An interactive VR training environment was developed to simulate the step-by-step procedure required to secure and reconnect an electrified vehicle. The system incorporates guided assistance, interactive components, and sequential task execution to support procedural learning. The training was delivered in a dedicated VR classroom equipped with multiple stations allowing simultaneous participation. A total of 422 automotive professionals participated in the training sessions. User perception of the experience was evaluated using a Likert-scale questionnaire assessing ease of use, perceived knowledge acquisition, and general satisfaction with the training.

Results: The results indicate a highly positive perception of the VR-based training experience. Most participants rated the system as easy to use and effective for understanding EV safety procedures. Over 70% of respondents assigned the highest score to knowledge acquisition and overall training value, suggesting strong acceptance of immersive simulation-based learning.

Conclusions: VR-based training represents a safe, scalable, and effective solution for technical education in emerging technological domains such as electric vehicle maintenance. The results support the use of immersive simulations to complement traditional training methods while improving accessibility, safety, and learner engagement.
