Is it? I would imagine the software does that. The battery really is a large array of commodity batteries made by panosonic. Tesla is doing the gigafactory for vertical integration and to bolster it's own supply. Obviously, they have done a lot of innovation around the pack in terms of heat distribution and cell construction, as well as the management system. The innovation is really about the macro-cell construction and the software to manage the array. On a micro-level it is just a bunch of commodity batteries wites into small cells, that make up a large cell array.
