BEVs

There's no doubt that politicians should be pressing for all sorts of restriction on car technology, from size to maximum speed/acceleration to driving licensing. But your attempts to justify the retention of ICE cars because e-car technology is not perfect seems .... peculiar.

An electric car battery is enormously heavy compared to that and has to be carried and accelerated continuously with nothing like the range. Takes a much longer time to replenish too.

I wonder if there will ever be battery technology to compete with liquid fuels?

An ICE only carries half of its fuel. It collects the rest from the atmosphere. BEVs don't have that advantage.The other drawback is the weight of batteries. I guess improving their energy density would allow smaller batteries to be used, if people can get over range anxiety. I haven't seen anything about "lighter batteries" in the sense of their mass density though. In the long term the drawbacks of BEVs will diminish I expect to the point where they don't give much concern.

First UK review of the XEV Yoyo Pro L7e,


UK web site, https://xev-uk.co.uk/yoyo/

Designed in Italy, made in Shanghai. Available in right-hand drive. Price £16K. LFP batteries but they look to me like they are in a vulnerable location. Overall I'd have more confidence in buying a Silence though I really wish they used LFP rather than NMC batteries.

EDIT: some info on prismatic LFP batteries:

I've argued all cars are growing too large, too powerful and too heavy, but since cars with engines are being phased out and won't be available from 2030 or 2035, it's correct for the focus to fall on how the battery powered car is evolving.

My appreciation of light weight cars and their benefits is frequently aired in this topic, I've frequently made the case for them including the Aptera, which appears a superb piece of work and looks gvfm next to the Microlino. Two very different, excellent cars.

BEV emissions will continue to rise if they do not become lighter and less powerful. Eventually, Grids will supply and balance mostly from renewable sources, cars and batteries will be made with renewable energy, by which time they will be much lower emission, but that won't happen with the lifetime of a typical car made today.

Any 'justification' for any form of motive power is based purely on lifecycle toxicity and carbon emissions facts.

Once our Grid is supplied and balanced mostly from renewable sources, once cars are made using energy from renewable sources, once battery materials are mined and refined using energy from renewables and there is less toxicity, then the situation will be completely different and the case will be cut and dried. I've said this many times.

It seems those of you who've been frustrated with what I have to say (as well as believing we're in the future rather than still burning colossal amounts of fossil fuel to make electricity, build cars and mine/refine battery materials) don't appreciate that beyond a given battery size, marginal return on lifecycle emissions become negative, compared with an equivalent ICEv.

That's to say, the environmental cost of extending the battery range beyond some point outweighs the environmental benefits. This point is made by a petrol hybrid VW Golf having similar or lower lifecycle emissions than its BEV Golf brother, reinforced by observing this gap widen if you compare the petrol hybrid with the Golf replacement ID.3 with larger batteries.

Well, there's always gulf between new and used. The Dacia Spring is now setting the benchmark for new electric prices so I reckon quadricycles, especially Chinese ones, need to come in below that. I noticed XEV UK are not listing a postal address or a dealership at the moment which would put me off anyway.

You're making the same point I have done repeatedly. But yes, I am concerned with considerable rises in size, power and mass of battery cars.

Please note, as I've mentioned before, I've consistently argued for the benefits of battery electric power particularly in smaller vehicles and have been recommending them to people since shortly after the Nissan Leaf appeared, almost a decade and a half ago.

It's remarkable that in pointing out the realities, both good and less so and despite stating that in a few decades, these emissions problems will be greatly reduced if the world decarbonises its electricity Grids, that some have taken such offence. However, "How easy it is to make people believe a lie, and how hard it is to undo that work again!" rings in my ears - and Government is still describing these vehicles as "Zero Emission", with many using this to lose their guilt from car use.

Perhaps this loss of guilt will greatly help consumption, for the truth has been out too long now for the ICE to continue for too many?

I'm not saying Lithium batteries are crap but there's plenty new tech on the horizon, like Lithium Sulphur batteries which can go 800 cycles without any deteriorated condition, or Aluminium Ion batteries which are just around the corner promising much higher energy density/kg.

Batteries are dirty (environmentally, and politically, the raw materials sourced in near slave trade conditions), expensive, not long on durability, hard to recycle and above all: a consumable. Like tyres or cassettes, only much, much more expensive.

How crazy (ie bad for the planet) would it be to make 100 million BEVs with a technology which will be replaced with something considerably less dirty and better in the near future, because Governments have been lobbied and persuaded this is the right approach? I'm very positive about HMG standing in where business won't in order to benefit us all and just possibly to see our planet left in a marginally better state for those following, but such a revolutionary move has to be meticulously planned for it to work as intended.

The new government intends to restore the 2030 target for sales of new cars. Here's the analysis from Greenpeace UK on the effects of 2030 rather than 2035.

"The impact of a 2030 ICE phase-out in the UK":
https://www.greenpeace.org.uk/resources ... in-the-uk/

It's from 2020 and I've suggested to them that they update it.
And I've had a reply from Greenpeace.

They don't have the resources to update it. So that remains the best analysis that I know of 2030 rather than 2035... unless anyone has something better...

But they did point me to how they they scored the parties' manifestos:
https://www.greenpeace.org.uk/take-acti ... e/ranking/

The relevant criteria for car-like objects are in Homes and Transport:
Recommit to phasing out new petrol and diesel cars and vans by 2030 and ban diesel HGVs before 2040. Alongside this, generate investment for 10 battery gigafactories by 2040, increase funding for an expanded EV charging network, and increase the mandate for local authorities and electricity networks to roll it out.

Do you prefer the UK Government's approach to BEVs to the EU approach, which is considerably different?

Greenpeace also has a problem with deep sea mining for, amongst other things, metal nodules to be used for car battery manufacture. I don't imagine they're too keen on many land mining practices, either.

And they'll have taken that into account when they produced their very clear desire for a cut-off date for sales of fossil fuelled vehicles and their criteria for scoring party policies.

I'm not expecting any dramatic improvements in energy storage density in batteries for car-like objects. There will be small improvements and slightly better battery management systems. Charging rates will increase and you can see that in the spread of what's available on current (!) BEVs.

Those IEA reports contain some very interesting analysis of sodium-ion batteries. They've made more progress in very small BEVs in China than I expected but the energy storage density is way below that of lithium-ion batteries. The reports identify the factors that will determine their future rôles in BEVs.

And those drawbacks have already been managed by millions of EV users. It's worth looking at Norway to see what happens when fractional sales get above 15%.
