A Xiaomi SU7 Ultra electric vehicle burst into flames while crossing the Hero Bridge in Nanyang, Jiangxi Province, China. Local fire crews quickly contained the blaze, and no injuries were reported.
Company Response and Preliminary Findings
Xiaomi confirmed that it has been in contact with the vehicle’s owner and has reported the incident to the relevant authorities. According to the company, on‑site inspection combined with data harvested from the car’s monitoring system showed that the high‑voltage battery pack was operating within normal parameters at the time of the fire.
The firm emphasized that the Battery Management System (BMS) recorded no warnings, error codes, or abnormal temperature spikes that would indicate thermal runaway. “Based on our initial analysis, we can rule out a self‑igniting battery as the cause,” a Xiaomi spokesperson said.
Investigation Still Ongoing
While Xiaomi’s data points to a battery‑free origin, the final cause of the fire remains undetermined. Local fire authorities will conduct a full forensic examination, looking at external factors such as road conditions, possible collisions, or foreign objects that could have triggered the incident.
Previous SU7 Fire Incidents
In February 2026, Xiaomi investigated a separate SU7 fire and similarly found no evidence of battery involvement. Earlier, in October 2025, a SU7 Ultra caught fire after a traffic accident, with eyewitnesses reporting that the flames engulfed the vehicle shortly after impact.
The Nanyang case differs because Xiaomi did not mention any collision in its initial statement, and the BMS data showed no thermal anomalies before the fire.
Impact on Xiaomi’s EV Business
Despite these isolated events, Xiaomi’s automotive division continues to grow. Data from China EV DataTracker shows that the company delivered 26,826 SU7 units in April 2026, accounting for 73.1% of Xiaomi Auto’s monthly sales in the domestic market.
At this stage, Xiaomi has not indicated that the Nanyang fire reflects a broader safety issue across its vehicle line‑up. The company says it will keep monitoring the situation and cooperate fully with investigators.
What’s Next?
Consumers and industry watchers are awaiting the official fire‑investigation report, which will clarify whether the cause was internal (mechanical or electrical) or external (road debris, impact, etc.). Xiaomi has pledged to share updates as soon as they become available.
