CATL and Schaeffler Just Signed a BMS Deal
On August 5, CATL and Schaeffler signed a memorandum of understanding to jointly develop battery management systems and integrated “X-in-1” power boxes for the European market.
The official statement talks about complementary capabilities — Schaeffler brings European functional safety and local production; CATL brings cell know-how and battery architecture. Schaeffler’s European BMS capability comes from its 2024 acquisition of Vitesco Technologies.
That deal gave Schaeffler ISO 26262 ASIL-D functional safety, EU homologation experience, and local manufacturing capacity — the exact things a non-European BMS supplier needs to cross the regulatory barrier. A European Tier-1 with local certification, local production, and local regulatory credibility.
A Chinese cell maker with the industry’s deepest data and the scale to drive cost down. A joint product tailored to European OEM requirements.
For Chinese OEMs expanding into Europe, this kind of arrangement is the fast path to compliant, high-quality BMS without building European functional safety capability from zero. For European OEMs, it’s access to the best cell data in the world without importing a non-localized BMS.
From where I sit, the CATL-Schaeffler deal is a compliance story on the surface. Underneath, it’s a data moat being built around the future of battery service.
