New National Standard for EV Maintenance Safety Takes Effect August 1st
A new national standard, "Safety Requirements for New Energy Vehicle Maintenance Operations" (GB/T 47439—2026), officially came into effect on August 1st. This standard outlines essential safety protocols for the maintenance of electric vehicles (EVs) and hydrogen fuel cell vehicles. It addresses critical aspects including personnel and facility requirements, preparation for maintenance tasks, risk assessment and mitigation, operational procedures, and overall safety during repairs.
The standard places a significant emphasis on the high-voltage systems found in EVs and the hydrogen supply systems in fuel cell vehicles. It details key operational requirements that must be followed before, during, and after maintenance work. Specific areas covered include the inspection of protective equipment and tools, confirmation of the work environment, identification of potential hazards, and the safe servicing of circuits operating at B-level voltages.
The implementation of this national standard signifies a proactive approach to addressing the evolving safety landscape of the automotive industry. As the prevalence of new energy vehicles, particularly those with high-voltage systems and hydrogen fuel technology, continues to grow, establishing clear safety benchmarks for maintenance is crucial. This standardization aims to mitigate risks associated with these advanced technologies, potentially reducing accidents and improving technician safety. Looking ahead, the effectiveness of this standard will depend on robust enforcement, ongoing training for technicians, and adaptation to future technological advancements in the EV sector, ensuring that safety protocols keep pace with innovation.
