Assessing the Electrical Risks in Electric Vehicle Repair: Results for use in Developing Safe Working Practices and Regulations

The rapidly growing number of electric vehicles (EVs) raises the issue of electric work safety in workshops. Traditionally, electrical safety has not been an issue in the automotive industry and the aftermarket. However, modern passenger battery EVs (BEVs) and hybrid EVs (HEVs) utilize battery voltages of 300–800 V, which causes a potential electric shock risk for certain repair and maintenance activities. Additionally, the large short circuit current and the fire risk with toxic gas emissions pose risks for service mechanics. Despite the potential risks, severe accidents have not been recorded. However, as the number of vehicles increases and the carpool ages, repair activities will become more common, which may result in accidents. In this article, a comprehensive risk analysis for EV repair activities is carried out. The results can be used in developing and communicating safe working practices and regulations on EV repair activities.
