DETROIT – As General Motors aims to be a leader in the electric vehicle market, a new patent for EV battery cells shows it might be shaking up production.
First reported by Motor 1, General Motors applied for a patent for an oddly shaped EV battery design. Normally, electric vehicle batteries are either rectangular or cylindrical. However, GM’s patent suggests exploration of an “L” and “C” shape battery intended to improve the cooling process, with gaps between the cells to extend battery life.
While companies like Lucid, Rivian, and Tesla employ cylindrical cells, according to Green Car Reports, GM chose large-format pouch cells because they were easier to make, and it allowed the company to ramp up electric vehicle production.
“We want to put everyone in an EV, and we have what it takes to do it,” CEO Mary Barra said in an event in 2020, per Green Car Reports.
However, a recent report from Bloomberg News, published by the Financial Times, suggests that GM has fallen behind its goals.
“GM bypassed its own best practices to rush the battery packs into production,” the report reads. GM installed “new fully automated battery assembly lines right away rather than testing them elsewhere first.”
