re: great technology in a fundamentally flawed business; assuming you are talking about BEV's in general, specifically the battery component.
The beauty of an ICE is how cheap the energy storage is. Take a Tesla with a 90kwh battery: currently the storage container -i.e. the battery pack- costs around 42k dollars. (based on Powerwall pricing of ~470$/kwh)We can store the same BTU's of gasoline in a tank with a retail price of <50 dollars. Even adjusting for efficiency of ICE vs electric and using super round numbers of 1 : 4 you can buy an 11 gallon automobile fuel tank for like 100 dollars, actually much less at OEM volumes. What's more, the ICE fuel tank, for all practical purposes, has an unlimited life and unlimited cycles. Fundamentally, that is a huge cost Tesla will have to overcome in the long run to make BEV's a viable alternative.
Thus, the real long term problem for TSLA is battery cost, specifically lifespan and replacement cost.
No one really talks about it, at least not relative to its level of importance imo, b/c TSLA offers resale value guarantee and their later models have unlimited mileage 8 year battery warranty iirc. But in the long run TSLA and owners of TSLA cars will eventually have to reconcile battery replacement/reconditioning costs with reality. At current battery pricing the cars will basically become boat anchors - really, really, expensive boat anchors - when the batteries degrade below whatever arbitrary threshold makes them worthless on the secondary market. Again at current pricing and just taking a complete guess of 50% replacement cost you are still looking at nearly 20k for just the pack on a 90kw vehicle. Ummm, no thanks.
Supposedly LG is supplying batteries for the Bolt at around 150kwh, but will those batteries match TSLA's battery performance? (lifespan and charge capacity over cycles) It's already well known Chinese Li-ion batteries can be purchased cheaper then Japanese battery suppliers; but the tradeoff is a much shorter lifespan.
Tesla is doing great things and I wish them the best, and yes I'm a fan. Having said that I have serious reservations and there is no way I would invest my money in them.
