What changed

The United States Patent and Trademark Office (USPTO) has granted patent US12583336B2 to SAIC MOTOR CORPORATION LIMITED for a novel battery module and electric vehicle design. The patent specifically details a cell restraining structure featuring an internal frame and external shell that create chambers for individual battery cells. Elastic elements within the frame are designed to elastically deform when pressed by a cell, exerting a restraining force that adjusts in response to the cell's operational expansion or contraction.

This patent grant signifies a new technological development in battery management systems for electric vehicles. While not a regulatory rule, it may influence future industry standards and product designs. Companies involved in battery manufacturing or electric vehicle production should be aware of this patented technology, particularly if their products involve similar cell packaging and management mechanisms. No immediate compliance actions are required for regulated entities, but it may impact intellectual property considerations and competitive landscapes.

Abstract

A battery module includes: a plurality of cells; and a cell restraining structure having an internal frame and an external shell fit with the internal frame to form a plurality of chambers for receiving the plurality of cells respectively so as to package and manage the cells. The internal frame includes an elastic element forming at least one first surface of each chamber, the elastic element being elastically deformed as being pressed by a predetermined amount by a corresponding cell received in each chamber such that the elastically deformed elastic element exerts a first force to the corresponding cell. The elastically deformed elastic element is further pressed or tends to recover in responding to reversible expansion or contraction of the corresponding cell in operation such that a restraining force to the corresponding cell is determined by the first force.
