Not trolling, just is it Tesla with all the smarts or Panasonic? Panasonic know batteries. And you would include EV tech? I have no doubt that they are in front, but did Tesla design all this from scratch? And why partner with Panasonic, there is no need to, to ensure battery supply. If this was the first EV model out, totally new, then that would be different, but I'm a little sceptical where Tesla actually fits in. What extra would I need to spend on another car to make up the range shortfall? Will their 64kW unit got 33% farther?
it is a collaboration. Tesla couldn't buy in enough batteries so built their own battery factory. They needed an battery expert to help them to save starting from scratch. Together they have come up with new proprietary chemistries (such as with less cobalt & possibly more silicon) that arguable Panasonic would not have/would not have needed to come up with on its own if it were still only making laptop and power tool cells.
Tesla became such a huge consumer of cells, that they were no longer constrained by the industry conventions/economies of scale and so they came up with (in collaboration with Panasonic) a new form-factor (2170) that improves the energy density further still.
Making their own batteries is one key example of the 10 year head-start Tesla have on competitors - no other car maker makes their own cells, which is significant because batteries are single most expensive component in an EV.
There is a world wide shortage of batteries (that has impacted other car manufacturers) so even if Tesla Car's was to go bust, their battery factory would stay in business.
