With how efficient battery electric vehicles are, when the batteries reach higher energy densities, we will see insane ranges.
If a Tesla's battery had the same energy density as gasoline, it would have a range of roughly 30,000 miles. Then again, the Tesla battery weighs as much as 200 gallons of gasoline.
This leaves so much room for gains in the BEV market as battery technology improves. One day they will look at current model Teslas the same way we look at Nissan Leafs from the 2010s with a 30-40 mile range.
Edit: 2000s -> 2010s Dear god
- akomtu 4y agoA fair comparison would be 80 gallons of gas and 120 gallons of liquid oxygen. Still, we are talking about 8,000 miles.
- DesiLurker 4y agoA fairer comparison would be to create a series hybrid with gasoline and minimum battery size. then the energy output of total gasoline + engine efficiency (~30%) vs battery + EV motor efficiency. the reason I insist this is because there is a thermodynamic efficiency maximum for engines so physics caps getting energy out of gas engines. then the numbers become more realistic.
- foxyv 4y agoYeah, most batteries have to carry their own oxidizer, so I guess this would be a more fair comparison. I guess that's an advantage of an air breathing engine/motor. However there are air breathing batteries. https://en.wikipedia.org/wiki/Aluminium%E2%80%93air_battery https://en.wikipedia.org/wiki/Aluminium%E2%80%93air_battery
