I was reading a blog today and this persons opinion is that the $ per kW costs of battery's can only go up drastically. At least that's how I read his blog and replies.
His math seems to me to be a little messed up. If a Tesla 85kW battery costs $40k wouldn't that be around $500 per usable kW in the battery pack? (I am rounding off and completely guessing) Lets get extreme and say the whole cost of the 85kW car is the actual cost of the battery and Tesla is losing money. That would be around $600 per kW in today's tech.
This author is claiming that future battery packs (2020) will cost at least $800 per kW or over $1500 per usable kW because the rare earth metals in Tesla's futures batterieswill cost that much. Yes in a reply to his own blog he claims he knows which battery Tesla is going to use. This guys got the inside scoop or is that poop!
Personally I find these kind of blogs a joke and don't bother replying to them because you won't change the minds of the haters. It's easier to post my annoyance here and get true feed back then feel better after reading your replies.
