Electric Vehicles are a key part of our tomorrow and how we get there. If we can get all the fossil fuel vehicles off our roads, out of our seas and out of our skies, we'll have a much better environment. This community is where we discuss the various different vehicles and news stories regarding electric transportation.

But were these problems ever solved for non EVs? I mean the bigger and less aerodynamic the car, the more energy it takes to move it. That's simple physics no matter what technology you're using. That's why IMHO SUVs and trucks are a pretty bad choice for an everyday vehicle.
Yes, they're easily solved with a larger fuel tank that can take you further before refilling. "Doubling the range" on an ICE vehicle is as simple as some extra plastic/sheet metal with very little cost. The same isn't true for battery packs. The physics of it is that gasoline and diesel have more energy density than lithium (or other current compounds) batteries.
But how is that an unresolveable problem?
Energy density of batteries is getting higher while prices are shrinking year by year. You can of course question if makes sense to keep throwing more and more batteries at a car with the size of a yacht instead of building a more efficient vehicle. But it's not unresolveable.
The unresolveable from my perspective is the underlying physics of more weight, big tires (at slow speeds) and poor aerodynamics (at higher speeds) increase consumption. And that problem was there all the time.
