HI there. I found on the internet that Tesla and panasonic have to invest $US5-6 Billion into Gigafactory just to have enough batteries for 500,000 units of cars. And it takes a few years to get the Gigafactory to be fully completed and fully operational. and this is the main reason Tesla is at the moment not profitable because the company heavily invested. If the big car companies like Toyota, GM and VM claim they will produce EV in a million in a few years from now, how are they going to get enough batteries? Do they invest heavily in their own battery producing plant? or simply just buy it from China? Are they going to be enough? 10 million units will need $US50-60 Billion investment is it correct? Thank you a lot.
