GREAT 1st step !
there is a good reply too, I will post it ....
"In the last 20 years battery energy density has doubled and the price per kWh has come down 10 fold.
I calculated that if we can get batteries to double the energy density of today’s packs and get prices down to $100 kWh from today’s $250 kWh it would only cost $100K for a 1 mWh pack that would give the truck a range of 800 miles at ~0.8 miles a kWh while only loosing about 4 tons out of a 25 ton cargo haul.
You certainly could do with less but 800 miles is around average for ICE trucks. That would give them almost 12 hours of straight driving at 70 mph.
Then stopping to charge at night the truck could be fully charged in 7 hours with a 150 kW supercharger style charger that is already available today."
And my Favorite reply "Exxon’s Tillerson just s**t his pants."
