Structural batteries do seem more cost / manufacturing / materials efficient rather than tucking "softer" battery platforms inside the car''s protective cage. I imagine the same structures that allow liquid coolant to circulate can also stiffen the battery platform, and the case itself a heat sink. The wiring harness must be madness.
Structural batteries are changing the way electric cars are assembled. Structural adhesives are replacing screws and welds to "glue" components together using a process called adhesive bonding.

This type of batteries is commonly referred to as “structural batteries”. Two general methods have been explored to develop structural batteries: (1) integrating batteries with light and strong external reinforcements, and (2) introducing multifunctional materials as battery components to make energy storage devices themselves structurally robust.
