  1. China disclosed on August 2, 2026, per a CCTV News report, the implementation requirements of recommended national standard GB/T 46991.1-2025, which sets accuracy and durability requirements for battery health display systems in light-duty passenger EVs.
  2. The standard limits the deviation between the dashboard-displayed battery available energy status and the physically measured value to no more than 5%.
  3. It also establishes reference levels for battery durability, giving buyers and regulators a standardized benchmark to gauge battery degradation and display reliability across the light-duty EV segment.
  1. 据央视新闻8月2日报道，中国已公开推荐性国家标准GB/T 46991.1-2025的实施要求，规定了轻型乘用电动车电池健康显示系统的精度与耐久性要求。
  2. 该标准要求仪表盘显示的电池可用能量状态与实测值之间的偏差不得超过5%。
  3. 标准同时建立了电池耐久性参考水平，为轻型电动车市场的电池衰减评估和显示可靠性提供了统一基准，便于消费者和监管方判断车辆电池健康状况。
