The success of small electric vehicles has been demonstrated in Taiwan. Small scooters and mopeds were extremely common forms of transport in the city, this caused horrendous smog as many were old and 2 stroke as well.
They bought in a system of electric scooters with removable battery packs, when your battery runs out you can swap it for a charged one at stations around the city, it has proven popular and reduced the urban smog a lot.
The removable battery seems like it solves a lot of the issues of charge time but is impractical in a 2.5 ton SUV (though it has been touted as an option for HGV`s with special stations). I think lightweight is certainly the future of electric vehicles.
I think the barriers to EV uptake are firstly cost, there is no possible way I could buy any EV on offer (our car is 20 years old but functioning perfectly well, my van 10 years old and still just about OK ). To replace them both with new similar electric versions would cost nearly £100,000.
Secondly if you don`t have your own driveway charging is very impractical for now, terraced houses or flats it`s impossible to home charge.
Thirdly the cost of electricity being insane right now, this month it became cheaper to run a petrol car than an ev for the first time, hopefully this is temporary.
Personally I don`t think there is much "green" about electric vehicles, using tons of expensive resources from around the world does not reduce emission overall.
I think converting existing cars to electric versions if the engines die is a good option. And a good way to resto mod classic cars.
There is certainly a lot of uptake in small stand up scooters (despite complete illegality ) and ebikes where I live anyway, showing that small stuff works well with batteries.
