Recently, a rumor has been circulating online claiming that ‘charging with poor-quality electricity can cause new energy vehicles to catch fire spontaneously,’ causing concern among some car owners. Experts and authoritative institutions have clearly stated that this claim is unfounded and lacks scientific basis.The term ‘poor-quality electricity’ usually refers to power with unstable voltage, frequency deviations, or high harmonic interference. However, China’s power grid adheres to strict national standards, and electricity supplied to both residential and public charging stations undergoes multiple stages of voltage stabilization and filtering to ensure compliance. More importantly, new energy vehicles are designed with robust safety features—onboard charging systems include multiple protective mechanisms against overvoltage, overcurrent, and short circuits, effectively isolating the battery from external grid anomalies.Furthermore, agencies such as the National Energy Administration and the Ministry of Industry and Information Technology have repeatedly emphasized that there are no verified cases of electric vehicle fires directly caused by ‘poor-quality electricity.’ Most vehicle fires are linked to battery defects, physical damage from collisions, unauthorized modifications, or battery degradation due to prolonged use.Therefore, the public should not panic unnecessarily. Car owners are advised to use certified charging facilities, maintain their vehicles regularly, and follow official safety guidelines for safe and worry-free driving.
近日，网络上流传一则消息称‘充劣质电会导致新能源汽车自燃’，引发部分车主担忧。对此，专家和权威机构明确指出，该说法属于谣言，缺乏科学依据。所谓‘劣质电’通常指电压不稳、频率偏差或谐波干扰较大的电力。然而，我国电网供电标准严格，居民和公共充电桩所用电力均经过多重稳压与滤波处理，符合国家标准。更重要的是，新能源汽车在设计时已充分考虑用电安全，车载充电系统具备过压、过流、短路等多重保护机制，能有效隔离外部电网异常，确保电池安全。此外，国家能源局、工信部等相关部门多次强调，目前尚无因‘劣质电’直接导致电动汽车自燃的案例。车辆起火多与电池本身缺陷、碰撞损伤、不当改装或长期使用老化等因素相关。因此，公众无需过度恐慌。建议车主选择正规充电设施，定期进行车辆保养，并关注官方发布的安全提示，科学用车、安心出行。
