General Motors has plans to function 4 battery crops, with one in Lordstown, Ohio already pumping out cells. With the flexibility to make its personal batteries comes the potential for customized configurations and kind components, one thing the corporate is contemplating taking to the intense. A current patent from GM exhibits batteries not formed like rectangles or cylinders, however Tetris-like blocks meant to accommodate extra environment friendly cooling channels.

The doc is presently simply an software, nevertheless it was printed very just lately in late February, with a current file date as effectively. All of this appears to point it is a new concept out of the automaker that it might have wished to guard rapidly. It begins by saying how battery cells are presently cooled, a minimum of in GM’s case. In vehicles just like the Hummer EV, we all know that is achieved on a module-by-module foundation with a cooling plate on the backside of the cells. In this patent, GM claims this technique can result in uneven cooling, which ends up in untimely battery degradation. As a aspect observe, different corporations use different cooling strategies to fight this phenomenon.  

GM’s concept is to make the cells in a tough “L” or “C” form in order that two cells mixed will go away a number of tunnels between the cells the place a cooling channel could be added. GM even has some uncommon diagonal shapes in there.
