EX30's battery: dendrites that made Volvo cap the charge at 70%
Production drift grew lithium dendrites in the cells — short-circuit and thermal runaway risk. 2,501 recalled; owners told to stop charging past 70%.
Volvo · 2026-06-18
What happened
In January 2026, Volvo recalled the EX30 globally over battery fire risk — and left China out, drawing double-standard accusations. In June, Zhejiang Haoqing Automobile Manufacturing, the Geely plant that builds the Chinese EX30, filed its own recall: 2,501 units, production dates 12 April 2024 to 27 December 2024.
A production deviation let lithium dendrites grow inside the cells — internal short circuit and, in extreme cases, thermal runaway. Until the fix, owners were advised to charge no past 70%. The recall (S2026M0066V) took effect June 18, 2026.
The battery that was excluded from a global recall in January came back in June with a 70% ceiling. The dendrite is a manufacturing decision, recorded in crystal.
Why it happened
- Production deviation grew lithium dendrites in the cells — internal short circuit, thermal runaway in extreme cases; owners capped at 70% charge until fixed
- 2,501 China-built EX30s recalled Jun 18, 2026 (S2026M0066V) — five months after the global recall left China out and drew double-standard accusations
- The interim advice is a 70% charge ceiling — the car ships with a third of its battery forbidden until the fix arrives
The lesson
Battery quality is decided on the production line, not in the spec sheet — a drift in one plant's process grew dendrites that a global recall missed and a 70% cap later confessed.
