Geely and ZEEKR: shaping the battery’s protective frame
A wider battery can compete with the space reserved around it for crash protection. Structural design becomes part of the energy-storage problem.
Canvas of Knowledge · 14 November 2026 · Illustrated explainerThe tension
The disclosure discusses balancing increased battery-cell space with protection during a side collision. Simply adding stronger material can also add weight and leave packaging constraints unresolved.
The proposal
The battery frame uses shaped side beams, connecting and fixing portions, and cavities with specified wall-thickness relationships. Its detailed geometry is central to the published technical proposal.
The evidence
EP4552882A1 was published on 14 May 2025 for Zhejiang Geely Holding Group and Zhejiang ZEEKR Intelligent Technology. It is an application publication, not a crash-test rating.
THE IDEA TO KEEPA patent description of protection is not independent evidence of a vehicle’s crash performance.
