Prius battery pack

Prius  battery pack
The Prius battery system is made up of 6 cell subpacks that are cooled and mounted in a much more practical fashion. The subpacks each have a thermal well, and high current connections. The bumps and sockets on the subpack sides allow a small air gap for the cooling air to pass through. Because the internal pressure in the cells would deform the plastic sides of the subpack, the whole 40 subpack assembly is compressed between two metal plates, so the pressure cannot deform the subpacks, and each subpack has a pressure relief valve. A cleaner easier to service pack for sure.
