Behind the Real-Person In-Vehicle Thermal Runaway Test: Battery Safety Validation Is Shifting from Extreme Marketing to Real-World Conditions

Behind the Real-Person In-Vehicle Thermal Runaway Test: Battery Safety Validation Is Shifting from Extreme Marketing to Real-World Conditions

In 2026, Geely Galaxy TT, together with CATL and CATARC Automotive Test Center, completed a real-person in-vehicle, single-cell thermal runaway test under conditions of 40°C high temperature, 96% SOC, and internal heating trigger, with the result being no fire, no explosion, and no smoke. After GB 38031-2025, the new national standard, set "no fire, no explosion" as a mandatory baseline, tests beyond the national standard such as gunshots, fire, and high-altitude drops have increased. Drawing on Ouyang Minggao's judgment of "whole-process safety," this article discusses the boundary between extreme testing and validation under real-world conditions.

Post‑Collision Repairs, Repair‑Shop Safety, and EV Fire Risks: Lessons from the Ningbo Zeekr 7X Incident

Post‑Collision Repairs, Repair‑Shop Safety, and EV Fire Risks: Lessons from the Ningbo Zeekr 7X Incident

A August 2026 Zeekr 7X pack fire at a Ningbo charger—after an unrepaired severe crash—highlights that EV safety depends as much on post‑collision inspection and compliant repair as on factory design. The article reviews how impact can hide cell, separator, harness and seal damage that later triggers thermal runaway; sets out China’s new repair‑safety standard GB/T 47439—2026 (certified two‑person HV work, isolated bays, lockout/discharge, pack recycling and records); corrects common flooding...

All-Solid-State Battery Safety Myth Shattered? Industry Experts Urge Consumer Rationality

All-Solid-State Battery Safety Myth Shattered? Industry Experts Urge Consumer Rationality

All-solid-state batteries have been widely regarded as the "ultimate solution" for power batteries by both industry and consumers, but their safety profile may be more complex than imagined. At the 2026 China Automotive Forum, FAW Group chief scientist Wang Deping issued a sober warning: once thermal runaway occurs in all-solid-state batteries, the consequences can be extremely severe. Academician Ouyang Minggao of the Chinese Academy of Engineering went further, telling consumers there is no need to wait for all-solid-state batteries. Japan's JISC released JIS C 8905-2 in May 2026, introducing mandatory thermal runaway propagation testing for solid-state batteries, while IEC 63254 entered CDV voting in April. Meanwhile, not a single vehicle claiming to use "solid-state batteries" in the 2026 market is actually "all-solid-state."

New National Standard Effective July 1: China's NEVs Enter Strictest Safety Era

New National Standard Effective July 1: China's NEVs Enter Strictest Safety Era

Starting July 1, 2026, China's mandatory new national standard for new energy vehicles takes effect. The standard covers three core dimensions: battery safety, electromagnetic compatibility, and functional safety. It imposes stricter requirements on battery thermal runaway, vehicle EMC, and intelligent driving functional safety. This standard directly elevates the safety baseline for Chinese export NEVs—providing quality assurance for overseas buyers while potentially changing market access thresholds.

New Mandatory EV Safety Standards Take Effect July 1: Battery Thermal Runaway Must Not Cause Fire for 2 Hours

Starting July 1, 2026, two mandatory national standards—GB18384-2025 "Electric Vehicle Safety Requirements" and GB38031-2025 "Power Battery Safety Requirements for Electric Vehicles"—will take effect. The new rules elevate battery safety from "5-minute warning before fire" to "no fire or explosion for 2 hours after thermal runaway," adding bottom-impact and fast-charge-cycle safety tests. Physical emergency disconnect switches become mandatory. Industry experts believe the regulations will fundamentally reshape competition, accelerating market consolidation and putting intense survival pressure on small battery manufacturers and low-end automakers.
