Re: Perhaps a hybrid would be a better solution?
Not sure why all the downvotes for this.
Personally, the technology I am waiting for is the gas-turbine series-hybrid. Basically an EV with an extremely compact high-speed generator.
Gas turbines can be much more power dense than ICEs because of their speed. Previously, power electronics was not fast enough to make a synchronous motor work at gas turbine speeds, but now they are becoming feasible thanks to GaN semiconductors etc.
The big problem with EVs is as TFA says: Charging them. And this is not just a lack of chargers, but a lack of generation and distribution capacity to power the chargers themselves.
If the UK had 230,000 EV chargers, the grid would fall over in an instant if even 1/5 of them were in use at any one time.
Therefore for EVs to be really practical we need decentralised power generation. Either from a compact gas turbine on the car itself (which could burn hydrogen or biofuel, at high temperature with very low emissions except CO2), or a lot of domestic wind and solar, or both.
Don't forget that if you are charging your EV when there isn't a surplus of renewable energy on the grid, then most of that energy is coming from gas turbines (and sometimes diesel generators) anyway. With a good 50% generation-and-distribution overhead before it even gets to your 97% efficient DC charger, 90% efficient battery, and 90% efficient inverter/motor. That puts it on a par with a 40% efficient ICE in terms of carbon emissions.
