It looks like my curve is a few years ahead of yours. I'd point out that my model is strictly based on how quickly BEVs and PHEVs have been gaining market share over recent years (using a logistic growth model). So the current trajectory has BEV hit 55% market share by 2028. This could speed up or slow down. I'm inclined to think that it may speed up for competitive reasons. Competition for survival is much more motivating that mere compliance.
I see. I looked at this in some detail about a year or so ago. My recollection is that if you look strictly at BEVs, and back out Chinese mfgs and Tesla, the growth rate of annual BEV unit sales is somewhere from nil to maybe 5% from the global ICE incumbents.
re those global incumbents, I think there is ample evidence in public announcements about BEV goals, along with some very strong incentives pulling on them which we can deduce, that indicate their markedly different pace of moving to EVs is neither an accident or soon to catch up to Tesla and the Chinese automakers. Toyota, for example, 7 months ago updated their EV aspirations to reaching 10% emission free vehicles in 2030 (note the press release below says emission free, as in Fuel Cell vehicles being looked to as part of the plan needed to reach that 10%!). Luxury automakers in part are an exception to this- we already see strong signs of Tesla’s growth in their segment accelerating their movement. So, I agree, competition is a big motivator- the luxury makers are moving more now, and when the Tesla pickup hits, Ford and GM will likely decide to move much faster with their key money making pickup businesses. Toyota, Honda,..., they may really be at 10% or less BEVs in 2030.
To me a projection of BEV supply will be far more accurate if Tesla, China, the luxury automakers and all the rest of the global automakers are looked at as different buckets.
One thing to note about China, my memory (and it’s been a while, so when I have more time I can double check) the growth in EVs there has been on the back of very limited range vehicles. In established markets (Europe, NA), such vehicles have not been too warmly received. That is, if I’m remembering correctly, that growth in China has not required growth in battery production to provide supply for 200+ mile vehicles. China can move fast and could soon steer towards actually stepping up to the kind of battery production growth that matches the BEV volume growth they’ve had, but, going forward at a scale to supply for 200+ mile EVs. Will be interesting to see if they do.
I see accuracy taking a big hit if we just put in one category the couple of dogs moving to EVs like they are chasing a squirrel with the overwhelming majority of dogs (global ICE makers) moving as swiftly as a dog being dragged to the bathtub.
