【忠阳车评】给新能源汽车系上安全带

Core Insights - Recent incidents of electric vehicle fires in China have heightened public concerns regarding the safety of new energy vehicles (NEVs) [1] - The probability of fire in NEVs is comparable to traditional fuel vehicles, but NEVs receive more scrutiny due to their rapid fire spread and higher intensity [1] - The development of NEVs is crucial for the global automotive industry's transformation and China's high-quality economic growth [1] Group 1: Safety Incidents and Causes - Major scenarios for NEV fire incidents include charging, driving, collision, submersion, and parking [2] - The root cause of these incidents is often thermal runaway in the battery, which can occur due to factors like battery membrane rupture from collisions or overcharging [2] - Effective management of battery thermal runaway is essential for improving NEV safety [2] Group 2: Standards and Regulations - Current national standards for NEV batteries are outdated, with the last version released in 2020, which inadequately addresses safety in extreme conditions [3] - The revised mandatory standard GB38031-2025 introduces stricter requirements for battery safety, including new testing scenarios and improved thermal runaway response [3] - The new standards will compel manufacturers to enhance their technology and safety measures across the entire production process [3] Group 3: Regulatory Oversight and Education - NEV safety encompasses not only product quality and standards but also regulatory oversight during usage [4] - Government agencies need to implement regular safety checks on existing NEVs and enhance public knowledge about safety [4] - Comprehensive training for maintenance personnel is also necessary to ensure safety in the NEV sector [4]
