Some of the Chinese EV companies are exploring battery swapping stations to get around issues with slow charging
That sounds like a sensible stop gap measure. The elephant in the room though is battery disposal. Questions are already being asked about how green EVs really are. Energy is green but the hardware, for want of a better word, is another thing. Long way to go yet.

If it worked like swapa bottle gas, that'd be great

I agree. Jeremy Clarkson used to go on about how much environmental cost was associated with making those batteries

the energy used for rigs to drill oil is mindblowing.

I expect future batteries to move away from lithium and already battery swapping is a thing in Asia but some Tesla are already prepared for it

I really thought by now battery swap stations would be everywhere.

That would require substantial engineering standardisation. Even in common platforms there'd be considerable difficulty I'd imagine with all the connections and whether the battery pack was a stressed member.
Given chemistry, it seems to me that there won't be a great leap forward in range vs battery charge rate and life so the reality would be buy a car that fulfils 95% of your yearly needs and rent a larger capacity (range) vehicle or take more time to get to your destination or fly...

@majorrage yes there are some major infrastructure issues still.
A problem is though if everyone swaps to electric by 2030-35 what happens to the old ICE cars... -

My understanding is the Chinese have done this
The last sentence I totally agree with. Electric cars are also I believe not so efficient on highways (no regen braking energy).

They're less efficient than in urban spaces, definitely.
Still far more efficient than a petrol vehicle in terms of realising potential energy in the fuel.

@nostrildamus said in Electric Vehicles:

There's a bit of regen but it is mostly due to gearing. They have optimal ratios, so too slow (urban as @nta says) and you are wasting power, and likewise too fast.
The loss on highways is also due to higher speeds and aerodynamic drag factors. Assuming that it is of similar altitude of course. You will use more energy on a sustained climb, some of which is recoverable on the way back down, but you are just recovering some of what you spent so that won't matter whether it a highway or not.
Some of it is down to Drag = cl 1/2 ro v sqd s.
The coefficient of drag, and s will be the same for any given vehicle. Ro (air density) will be roughly the same on any given, day but velocity is squared so has a massive affect on drag and efficiency.I think that Porsche have a geared EV now that improves efficiency over a range of speeds and driving conditions to overcome some of that.

@nostrildamus said in Electric Vehicles:
@nta yes I am also now thinking will the govt let me buy an electric car that carries 1000 kilos (does towing count?) and writing it off as a trade vehicle
Good article. EVs have reputation for being shit at towing due to the range reduction but a lot of that is the old "range anxiety" of ICE owners. Tesla made a point of it with the Model X marketing that it could tow successfully. Given the weight of EVs and the weight distribution between the vehicle and the trailer, they should actually tow really well (range issues aside).

yes that article hints quite strongly they could perform better-higher torque and lower centre of gravity and more weight suggests to me they don't get pulled so jerkily as a higher, lighter ICE car.

@nta said in Electric Vehicles:
@snowy additionally, nobody talks fuel efficiency of ICEV towing. The range of a petrol or diesel vehicle is drastically affected by load in the same way as EV.
I'm torn regards diesel. Much more comfortable drive in the hilly (NZ) countryside, great engines but crap fuel...(for the environment and health).

Modern engines it’s nowhere near as bad as I thought. Old man has a petrol Highlander. Rock solid 9l/100k. Rises to 11 towing the boat.
So if electric is also 20% ish range reduction then that’s still strong given most are 2-300 miles these days.

For sure. If I tow my digger around on the trailer fuel consumption goes up considerably behind the diesel hilux. If I tow the same trailer over a longer distance with the V8 car it isn't so noticeable.
Range anxiety isn't a thing when people can just pull over and fill up though.
E.G. If I was to tow my boat down to the bach with an EV I think that I would need 3 half hour stops to recharge and add 30% to the time traveling. So it is an issue depending on what you are doing.
