By my calculation, based on a quick google search, a Tesla electric car battery is around 80-100kWh, so that's c. 8-10kW power demand required for a full overnight charge (keeping maths simple, assuming 10 hours duration). Add that up for multiple vehicles and there is a huge demand, especially when you compare to current typical average levels. If each vehicle is broadly equivalent to 3-4 houses, then it becomes clear that many concurrent vehicle charging loads of that or more do present a big problem for electricity supply industry at local distribution level.
Unless a property has 3-phase, the maximum wall charger draw is 7.5kW, limited by regulations AFAIK. 3-pin draw is 2.4kW? Most cars maximum AC draw is 11kW (only 3-phase again) but some can pull 22kW - so there are practical limits.
Your point on local infrastructure struggling with a street full of cars pulling 7.5kW is well made though. My village with its 1950s overhead cables and ancient transformers will no doubt suffer problems when we are all charging our cars.

You may be right about the regulations, I didn't research that far. Domestic 3 pin limit is c.3kW (13A at 230Vac nominal rms) though a commonly available industrial 'blue' single phase 32A plug and socket on dedicated circuit could allow 7.4-7.5kW. Perhaps that's the technical basis for the chosen regulation?

Credit where it's due, it was Dave20046 and then timwilky who made the point originally.
The simple fact is that there was no wind, very often in winter in UK we get stuck in a high pressure area where the isobars are social distancing - some of the coldest weather is during highs as no cloud cover ...
Yes understood and I know it does happen - wind is a variable source, that's why you need a lot of turbines spread out throughout the country and offshore if you want anything like predicatble overall supply capacity at naional level (that will be noticeably lower than total connected machine capability).
I was more wondering if some windfarms were constrained off i.e. paid not to generate because there's surplus, cheaper gas or other baseload supply available that's not as easy to switch off. You'll no doubt be aware of the 'shock' style press headlines that have appeared in the past but it's just a quirk of the balancing market with variable supply & demand and the fact that large scale electricity storage is not prolific.
Today only about 13% supplied by wind, 0.5% by solar and the rest by gas fired power stations ( what a waste ) nuclear, biomass cables across channel and even about 7% by coal fired stations.
Gas is still cheap globally but burning it (or biomass for that matter) doesn't attract the bad press of 'dirty' coal. I agree it's not great but I guess money rules - selection of generation is still decided by economic factors, not moral ones.
I was surprised at the gap when checking my own home supply bills last month, so much so that I even stopped briefly to consider swapping out my electric kettle for a stovetop one! (It turned out 1kW electricity was almost 3 times the price of 1kW gas for my usage - though build-up is skewed a bit by daily standing charges on my contract - it's not as simple as per-unit price differences so more analysis required.)

They are expensive and thats the biggest problem for consumers IMHO. Its certainly the bit that's holding me back. I think legacy car makers want to see a return on their investment at a speed they would with a normal ICE car amd fail to allow for the costs of converting to electric to be recouped over a longer time frame. Tesla only recently started to make profits and they have been building EVs for 10 years.
I think they think of a number they believe early adopters will stomach and then add on the value of any incentives available. It would be better for UK customers to negotiate a price prior to the PICG and then claim the grant afterwards. That way the "OTR" prices advertised would be more like the list prices and any grant is a bonus. Right now all EV prices are advertised with the grant taken off. I'm hopeful they become more affordable to owner-dirvers in the next 2-3 years, otherwise we are waiting for the lease market to start releasing second hand ones.

Before the 2030 deadline, production lines will have to radically adapt to build a wider range of EVs in a profitable way, while the UK’s charging network will need to grow exponentially to cater for demand.
Hahahahahaha! - Why?
When the deadline hit's, it's EV or public transport....why on earth would the manufacturers take a hit on profits for something people just 'HAVE' to have?
Additionally 2nd hand sales of EV will in all probability be fairly unrealistic in many cases as by the time you are done with it, the 5-20k battery pack is in all probability shagged out (end of life) anyway.

:smt018 I thought it was the point that kicked this whole thread offYou're assuming that the government want personal transport for everyone and current methods just need translating from petrol to electricity.
There are several different scenarios for the future.
If vehicle ownership is unaffordable then rental systems will increase. Why buy a depreciating asset if you don't need it every day?
We may be looking at a world where if I need to get from A to B I'll tap my app, an autonomous vehicle will arrive, take me to B. I don't need to worry about buying it, maintaining, parking or charging it.
Is it as convenient as what we have today? No.
We need to stop thinking about the future as an extension of the status quo and consider alternatives to mass individual vehicle ownership.

On Tuesday in brilliant sunshine the other half and I went for a bike ride. She on an electric bike due to arthritis. As we peddled along with her zipping up the hills there was me thinking that an e-bike could be the solution to overcrowded polluted roads. Today as I sit in the lounge with the rain and sleet hitting the patio window I have probably changed my mind!
I think in the future we will be curtailed one way or another re mobility. Either that or the world human population will have to reduce significantly.

It may be a fair cop, guv. I was referring to the technical point about local electricity distribution not being able to cope, subtlely different to having enough number of charging points which I think is where this thread started.
But, in any event, I knew it wasn't me and thought it right to admit it!:smt083

Can't see this ever quite happening myself. Maintenance and cleaning will be the issue. A lot of current owner-driven taxis are pretty grubby inside - I wouldn't want to sit in many for extended periods when sober.
Also, would you risk being the passenger in a poorly-maintained autonomous vehicle at risk of crashing?
IMHO, cleaning and mechanical maintenance will be the areas where owners seek to compromise in order to maximise the asset availability, leading to a pretty unpleasant experience (depending on previous occupants).
We need to stop thinking about the future as an extension of the status quo and consider alternatives to mass individual vehicle ownership.
Although I do concede that is a good point. I recall a quote I heard in the past: "A developed world is not one where everyone has a car, a developed world is one where the well-off use public transport" (Source unknown).

I don’t think I articulated it very well but was wary of cabling capacity to houses as well as grid supply and if original designers had anticipated large draws from every house hold down the line . Mainly an observation triggered by working in an office where the lady folk thought it was a good idea to put an electric heater or two under all of their desks and kept flicking the fuse box back on until the cabling in the walls started burning . I’ve just removed fabric cabling and wooden back boxes from my own home, but hopefully city infrastructure is a bit more up to date that domestic one offs! And then there’s the more obvious ‘is there enough power available’ , looks like they’re working on it though.

Legsilation is often a nudge for suppliers rather than consumers, or an attempt to give them confidence to invest in what's needed to make things a reality. A bit chicken and egg.
Things will change a lot in the next 10 to 20 years. Technology moves fast, especially when there's profit possible.

There will no doubt be exceptions for emergency vehicles (much like the exceptions which allow police cars to have their engines running all the time) but they may not be needed.
Considering fire engines, they spend most of the time in a purpose-built shed, so can always be topped up. Police cars could perhaps do with less boot space, to give them a much longer range.
Or maybe they'll have pluggable batteries. When it's industrial, there'll be plenty of options ...
My favourite is the first all-electric ferry in Norway, built in 2014. It has a 1MWh battery (10x the biggest Tesla) but charges enough for each trip during the 10 minute turn-around. To do this, they have a battery in the port which is constantly charged then dumps its charge into the ferry when it docks as the grid wouldn't cope on its own.
I'm still holding out hope for hydrogen though ... :-)

A fire engine on scene at a fire or a crash scene using the PTO can be on for multiple hours from an ICE. You'd need a serious battery to pull the same power for battery, or a large generator.
Hydrogen is too expensive for smaller vehicles currently. I can see it being used for industrial purposes/the road transport network more so due to the much larger volumes they consume. Then cars will trickle in as this becomes more accessible and cheaper.
There's some good battery information in this video (https://youtu.be/-PL32ea0MqM?t=603) talking about the degradation of Lithium Ion Batteries, and that Tesla is using a LFP battery in the Chinese market for the Tesla 3 due to the better long term performance.
My friend is a Firefighter, and says that EV fires as the most difficult to deal with. Essentially the best/only way to deal with them is to submerse the car in water for 24 hours.
This is the advice Tesla give on a Battery fire, link to page/documents below.

The good side of a drastic reduction in the burning of fossil fuels will indeed be 'cleaner air' and a potential to reduce or even in an optimistic view to reverse climate change.
The downside will be to follow-on political instability in nations that rely on the export of Oil and LNG based resources.
It will indeed be interesting times ahead, in more ways that one in all probability

Non-motorway roads are getting better served now BP and Shell are getting behind charging points in a big way. BP have just installed 6 150Kw chargers near J27 M6 on A5206 for instance.
The problem with motorway services has been that Electric Highway has almost a monopoly on non-Tesla chargers. Their chargers are old and basically crap, unable to work with the latest vehicles. This announcement is great news, doubling the capacity at each charger and installing something modern that can be maintained and works. The HPC super fast chargers are still a way off I suspect, but add in the Ionity network and now BP / Shell putting chargers near motorways things do look better.

Maybe it is all a way of controlling people's motoring - a network of motorway charging points but no leisure rides to out of the way places, they'll be thinking of banning petrol engines next !
most people dont buy cars any more and instead lease so come 2033-2035 petroleum fuelled cars will go back to dealers and at that point people will only be offered electric powered vehicles. the returned vehicles will be decommissioned.
so in reality we have until 2035 at the latest before most vehicles will be electric. unrealistic deadline.

By the time people have paid the inflated prices to charge their car at motorway and other charging points owned by companies any 'fuel' savings will be non-existent. As for charging at home I am sure the government will also want chips in car charging leads and smart meters to know when a vehicle is being charged and have a different rate for electricity ( something has to replace the loss of duty on petrol and diesel), the government will just wait until they have a trapped audience of electric vehicle users ( trapped by legislation of their making - aided by Princess Carrie nut-nut whispering in Boris's ear ) and then the bad news will start to arrive, at the moment they are wary of scaring people off the already eye wateringly expensive electric vehicles and will bide their time.
As for a universal car battery - I wouldn't want to drive my brand new BEV into a battery swap station and drive out with an abused 5 year old battery in place of my brand new one. Also battery tech is evolving pretty fast and a battery tech could well become obsolete within a few years of its introduction. At present keeping a Lithium Ion battery fully charged damages them, which is why the 'x minutes to 80% charge ' appears on BEV adverts, the 80% figure was not chosen at random. Also the sneaky using of car batteries to keep grid running in the face of renewables that do not show up for days on end is a con, battery life is dependent on charge / discharge cycles, and although the grid will offer cheaper rates if you sign up for the scam your battery will go through many more cycles than shows on the milometer - you could buy a 3 year old BEV with 10,000 miles on the clock, but the battery has actually done the equivalent of 200,000 miles as far as battery cycles are concerned the previous owner has saved money at the next owners expense.

I agree with Bibio on one thing----cassette type battery swapping will be the way forward. You wont own the battery so no worries about it getting shagged out,you will only buy the amount of energy it contains, which will be measurable. Its the way to get over the elephant in the room which is time spent charging/refuelling. Motorists want and need to make progress and that means refuelling in a couple of minutes, not tens of minutes or even an hour or more. Solve that and electric will become mainstream

Problem is with BEV that the battery is a massive part of the car, is very heavy and takes up an awful lot of room ( my brother in law is working on Jaguar electric car design at the moment ). The BEV is literally built around the battery, not like a torch where the batteries pop in and out easily. Motorways kill batteries, for a motorway trip ( unless you want to stay with the lorries at 50/60 mph ) expect to get 60% of the range it says in that shiny brochure you got with the car...

I don't have an electric car or motorbike but I have a pedelec , the type of bicycle that requires pedalling for the electric motor to assist. It was good while the battery lasted ,but it only lasted a year before refusing to hold a charge, and the range on generally level ground was only about 16 miles on a low setting, not the 30 or so miles as claimed by the manufacturer. A new battery is about £360 the last time I checked with the bike shop but is claimed to give a range of about 40 miles or so. I will get round to a new battery one day. Without motor assist it is like wading through treacle so really can't be ridden with a flat battery.

No doubt on electric vehicles as well as insuring for accident and fire ( fire seems to be a real possibility ) or theft they will introduce battery insurance. Depending if you have signed up to the 'lend us your battery' scheme to keep national grid going when renewables stay in bed I have no doubt you battery insurance premium will skyrocket, as the 'protect the grid' scheme will put the battery through many more cycles than normal driving will. They need to have a register to check if the second hand BEV you are thinking of buying has been used on the scheme, because the speedo trip may only say 10,000 miles but the battery has done 100,000 or more. I have no doubt places will spring up ( like the mileage 'correction' services we have today ) that can reset the battery charge / discharge history memory to a lower figure. The next environmental disaster my well be how to get rid of the toxic chemicals that millions of used but not really recyclable BEV batteries will inflict on the planet - the volume will be much, much greater than the paltry amount of nuclear waste we have accumulated over last 70 years or so.
Solid state batteries will replace the current generation of lithium ion, probably within the next 5 years. Then you will essentially have nigh on the 'perfect' balance of weight, range, size, charging capability & lifetime too.

The EV world has come a long way in a short time, it'll continue at a rapid rate now EV's are going to be mandatory in a lot of countries.
Electric vehicles are obviously being forced on us but what forces are at play here, companies with vested interests, individuals queuing up to line their own pockets possibly. I am not suggesting ,of course, like some suggested happened with recent Covid related contracts, that private companies with connections to people in government could benefit from the change to electric vehicles.

Solid state batteries will replace the current generation of lithium ion, probably within the next 5 years. Then you will essentially have nigh on the 'perfect' balance of weight, range, size, charging capability & lifetime too.
Really ?!
How long will the electric car's battery last?

Really ?!According to VW at their "Power Day" they expect to have solid state batteries from 2025. I'm sure these will only be in Porsche and top-end Audi products, but eventually it will trickle down to less expensive vehicles. Tesla, LG Chem and General Motors are all working on solid state technology.
There's a good chance one of the mobile phone manufacturers will develop solid state technology before then, as they will also benefit massively from it.
Whether solid state will be all that DJ123 states remains to be seen. It must be 'better' than current lithium-ion tech though, otherwise there would not be so many billions being spent on R&D?
It will certainly be interesting to see the progress and innovation. Some things are real game changers, the ideas drift around for years and then suddenly someone makes something commercially viable and the whole scene changes almost overnight.
Witness the demise of the CRT television. Flat screen LCD monitors were bubbling along with small expensive screens, and then the technology to make LCD screens big enough at an affordable price to make it real, then it progresses into screens bigger than you can fit in your sitting room for less than your old CRT cost 25yrs ago.
A lot of the next things have already been thought of, it's often a question of making them real. Manufacturing engineering is a much under-rated and mis-understood discipline.

Last i heard/watched on the subject part of the commercialism of the SSD battery is being able to produce it on a Lithium Ion production line. That would make it more commercially viable ,as the mass production will drive the cost down and allow the tech to be more widespread.
Toyota, VW & Mercedes (and others i would assume) are investing in SSD batteries.

ok there is a plan... car bodies incorporating graphene and will be the power source. graphene 'battery's' charge in mins and since there will be no heavy battery's then the car will be lighter so will go further on a charge. if they incorporate graphene/solar body then will charge for free when it can e.g. sunny.

It's out there, still looking to find uses for it. Graphene charges fast but also discharges fast, more like a capacitor than a battery. I've seen some battery mock-ups and they were charging/discharging in seconds.
Don't know how viable a battery from it actually is.
Bloomin expensive, though getting cheaper, last time I was trialling it we were looking at $10,000/kg

Size for size batteries store a lot more energy than a capacitor, but absorb and release it slower. Capacitors are great for absorbing energy quickly and releasing it quickly. The voltage of a capacitor drops markedly as it discharges where batteries maintain voltage until they are pretty much empty. ( at 11.9 volts a lead acid battery is pretty much flat ).

I agree with Bibio on one thing----cassette type battery swapping will be the way forward. You wont own the battery so no worries about it getting shagged out,you will only buy the amount of energy it contains, which will be measurable. Its the way to get over the elephant in the room which is time spent charging/refuelling. Motorists want and need to make progress and that means refuelling in a couple of minutes, not tens of minutes or even an hour or more. Solve that and electric will become mainstream

How many batteries will the average motorway services or 'swap station' keep ready to go, and how many different types and voltages ? Every car maker will probably specify a different battery, and as cars age and the tech improves batteries will become obsolete pretty quick. Turn up at the mortorway services with a 5 year old BEV and they will probably say. 'sorry mate, we don't do that one any more'....

Drive into the swap bay, jack up car, remove battery pack by means of an operative, fit new pack, diagnostics to make sure it works with the car, leave.... Probably more than the 5 minutes folks are looking for?
How long before these battery swapping facilities are as ubiquitous as petrol stations? Or charging stations come to that? (There are more charging stations than petrol stations now in the UK)
I don't see any mainstream manufacturer going down this road, as there is no infrastructure to support it. VAG/Mercedes/Kia/Hyundai have all put their shoulders behind Ionity. Tesla has the Supercharging network. Shell/BP/Esso are rolling out high speed chargers. I think faster charging will be the way forward for road tripping and overnight / destination / workplace charging taking care of daily commuting and shopping miles.

If they were accessible for a quick, tooless change (but then theft would be a mega problem) and didn't weight a ton I actually think it's a good idea ... at least until instant charge is a thing. Or even as a backup option in an emergency like the Nokia days.
I imagine the batteries are monsters though, unless they introduce a supplementary battery for the above emergency purposes.

Not very mini like handing, it's RWD and getting a rep for being tail happy. Honda have majored on the tech though, screens everywhere!
Also fearsomely expensive for what it is, and very modest range on the 35kWhr battery (something like 120mls real world).

If they're counting the lamp-posts in London as charging stations, then it's not surprising, but also not useful. Given that it takes at least ten times to fill up an electric car, you'd need so many more to get even close.
Luckypants
23-03-21, 02:19 PM
Well clearly not counting lamp posts, only those with charging capability.
Charging a car needs a mindset change. You think about charging overnight or at work or at the gym etc. You charge your car when it is busy doing nothing. Its not like a fossil vehicle where you need to stand over it filling it up, it can be left to safely charge on its own. So lamp post chargers are valid public charge points, as a 4 hour charge while you are at the cinema or watching the rugby or shopping or a 100 other things is a a decent top up for most people. My car would add around 40 miles from a lamp post charger in 4 hours.
If you need to crack on a long journey, that is when charge times becomes a big deal. Almost all the recent crop of EVs will charge at 80+ Kw, meaning a 20-80% charge is quick. What you need is 100Kw+ chargers on main routes and these are coming. Ionity, Gridserve, Shell and BP to name the main players are rolling out 150Kw to 350kW chargers. VW ID.3 and ID.4 cars can charge at 125Kw, so fill 20-80% in less than 40 minutes. That's the time it takes to get lunch. The fastest 250Kw Tesla chargers will do the same thing in 20 minutes, which is a pee stop / coffee stop.
If you want to drive 600 miles in one hit with no breaks, then EV is not for you.

Well its been at the detailers since the weekend, so only got to drive 100 miles total. Its very quiet, very smooth and very comfortable. There is loads of tech. I need to get to grips with, but all seems very easy to use. It has all the EV traits of instant torque, punchy overtakes and weirdly swift progress. We are having to recalibrate brains on speed as no engine noise means you can end up speeding if not careful.
A great feature I'm liking is the adaptive re-gen braking, if I lift off the accelerator the car coasts until it 'sees' a car ahead or a junction/bend/roundabout/etc then it starts to slow the car with re-gen braking until it gets quite strong. If you do nothing, it slows to a stop where appropriate. If it slows for a bend, it goes very slow around the bend. Obviously you can intervene and then it drives as you want it.
Also excellent is the new adaptive cruise control (not an EV only thing I know) linked to traffic sign recognition. If the ACC is set to the speed limit, the car will slow / speed up to the limit without driver input. Its kinda weird and fun at the same time.
I'm loving it so far and cannot wait to get it back.

My van has something similar. At least I thought it did until I realised it was the hand brake binding on the rear drum :-)

The brake lights operate when braking force goes above a certain amount. My wife followed me home from picking it up and said I seemed to be using the brakes a lot, but I wasn't.
It doesn't check the rear camera for hazards before braking as far as I'm aware :D
