+1 Your last point is absolutely key to sizing up the competition. A competitor is only as big as the GWh they bring to market.
In 2014, Tesla brought about 2.5 GWh to market, which was about 35% of the EV battery market production. Battery production was 7.2 GWh in 2014, up 54% over prior year. Panasonic gained 3 points of market share.
EV Battery Makers Market Share 2014 vs 2013
So Tesla wants to bring 50GWh to market by 2020. Will competitors bring 100GWh in that same time, or will Tesla continue to have a 1/3 marketshare even in 2020? I'd be happy if Tesla just retained a 1/5 marketshare, but this could require competitors to build out 200GWh of capacity. So at this point I do not see what competitors have the ambition to scale even to 50GWh. If any do, we should be hearing about their own gigafactories soon.
Excluding Panasonic, if other battery makers advance 54% per year from 4.5GWh in 2014, that would lead to a mere capacity of 60GWh. So at this pace, the industry brings about 110GWh in 2020 and the Tesla Gigafactory has a 45% marketshare. So the competition really needs to pick up the pace.
Thanks for for the information . Battery supply allows for pricing power, without pricing power the business
is not investable in my view.
