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.

Changan Mazda EZ-60 Claims 7th Consecutive JV NEV Mid-Size SUV Sales Crown

At a critical juncture for joint-venture automakers' NEV transition, the Changan Mazda EZ-60 has achieved something remarkable: seven consecutive months as the best-selling joint-venture NEV mid-size SUV. While domestic brands dominate China's NEV market, the EZ-60 stands alone as the JV segment's sole viable contender. With a starting price of 139,900 RMB, 86.5% high-strength steel body, and the world's first 100-inch naked-eye 3D HUD, it is rewriting the competitive rules for JV NEV SUVs.

150,000 km Becomes Ride-Hailing Battery "Death Line" as 177Ah Cells Swell in Batches

A batch of ride-hailing vehicles that have reached 150,000 kilometers is experiencing concentrated battery swelling, leakage, and insulation failures. The affected vehicles are primarily equipped with 177Ah lithium iron phosphate (LFP) cells, with failures clustering between 150,000 and 250,000 km — squarely on the manufacturer's "8 years or 150,000 km" warranty threshold. Ride-hailing vehicles operating approximately 80,000 km annually with 1-2 charges daily are challenging existing battery safety standards and warranty systems.

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 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."

MIIT Officially Bans "Cascade Utilization": Used Power Battery Recycling Enters Full-Chain Regulation Era

On July 31, 2026, China's MIIT issued an announcement abolishing and revising policy standards for "cascade utilization" of used NEV power batteries, formally removing the concept from industry management. New rules require retired batteries to undergo dismantling, crushing, and smelting for resource recovery, strictly prohibiting simple reassembly and resale into high-risk applications like e-bikes and energy storage systems.

Huawei's Whale Battery Platform Meets New National Standards 5 Years Early

Huawei's Giant Whale Battery Platform has met new national battery safety standards five years ahead of schedule. The platform employs a three-level architecture spanning cells, battery packs, and vehicle systems, combined with 100% X-ray inspection and AI-driven quality checks to achieve deep control over the entire battery production chain. HIMA demonstrated the platform's systematic protection against five major fire triggers including short circuits, overheating, and water ingress.
