How long before we will get a genuine 400 mile range for under £40k in an electric car?
Within the next 5 years?

I am about to change car and wanted electric but realised there are 3 regular journeys I do each month that would require multiple stops to charge.
1 stop to charge for a 45 minute fast charger is tolerable (inconvenient but tolerable), 2 stops is too much.
And the lack of chargers and the even greater lack of working charges makes it impossible to consider electric.


So the question remains, how long until electric cars will get close to the range of a petrol equivalent ?

A Genuine Real World 400 mile range would cover my usual long trips, but next month, we are going to Germany, 800 miles each way, with the wandering around, and an overnight stop each way, but still the faff of locating a working charger.. (yes, they have problems too) so till we have a real 400 mile range it's a nono.

I might add, the Korando is doing VERY well indeed and can refuel in 5 minutes. On top of which it is so darned comfortable.

Range is less of a problem. It is the long refill time that matters.

Then add 2-3 other cars waiting in front of you. Then it becomes utter frustration.

We need wireless charger for cars so that you can get charged while driving on motorways.

I wonder if there'd be issues for people with pacemakers - a phone charger they are not.

Watched a video clip this afternoon about a stillborn prototype EV that came from what was left of Saab, it had a 621 mile range thanks to an enormous 175kWh battery. It was developed in secret starting around 2019 and is only now starting to surface because the parent company is in dire straits and there is hope another may step in to save it.

Because of the requirements for batteries, I'd be much more in favour of making EV's more efficient than giving them bigger batteries. So better aerodynamics for motorway speeds, and lighter weight for urban running.

I was admiring the new Hyundai Ioniq 6 in a dealership the other day. It has impressively sleek looking lines (though I have not seen a Cd figure for it). All versions use the same 77kWh battery, but the 2wd model has a longer quoted range of up to 338 miles as opposed to 322 for the 4wd.

Within five years? I expect so, yes.

In the meantime, if you do mostly short journeys and longer ones a few times a month, consider a PHEV

Not worth the huge purchase cost if you do very low mileage. You may well either keep and fettle your exsiting car at a vastly lower cost, or buy as cheap a 'standard ICE' car you can and pocket the rest, as the saving on fuel costs vs electricity is likely to make the payback period very long indeed, probably longer than the time you'd keep the car.

I think that PHEVs are only useful if you do a reasonable annual mileage (buty not too high) by way of smaller-average commutes and longer occasional weekend / holiday trips. Especially as most PHEVs tend to be bigger cars because of the doubling up of the drive systems and extra battery space requirements. A range extender might be a better alternative if the price is right, but most of these cars aren't exactly 'cheap' these days.

i think the only rational solution would be a battery which can store more energy per kilo. A typical EV battery can weigh several hundred kilos, and unlike a tank of petrol it doesn't get any lighter as the journey progresses.

Charging time and queuing for it are another difficulty. I think it will be some years before these problems disappear - if they do :-)

Presumably, once you've got enough range for the 500 mile commute-whilst towing a caravan-and presumably a catering wagon-and some kind of urine receptacle -brigade, they can just charge overnight like a sensible person.

I don't know how much an electric motor or two weigh, but quite possibly more than a modern small turbo engine (e.g. 1.2 puretech - only 84kg) which is sufficiently powerful (up to 150hp) for most car sizes. The weight of a gearbox is probably more than the hefty copper wiring an EV needs, but you can't get away from the fact that an enormous and increasing amount of fossil fuel derived energy is being used to move zillions of tons of battery from a to b on a daily basis. Inductive power would make more sense in the long term. The aphorism 'never sell Shell' has some time yet to run!

Electric range development - Brit_in_Germany

The extra weight of an ICE drive train seems to be approx. 100 kg upwards, so the net additional weight for an ev will be significantly less than the weight of the battery pack.

I’m not a full time EV user, instead a frequent one, and I have never queued for a public charger.
Next time you’re out and about, have a look for rapid chargers, there are quite a lot of them nowadays, and I’m fairly confident that there’ll be more idle than in use.
Electric range development - paul 1963

I agree MCB, plenty of vacant chargers round by me, the industrial estate that the company I work for is based has a bank of 10 chargers that apart from us and a guy with a Tesla never get used, supermarket opposite where I live has 4, I'm seriously considering a full electric for my next car...

Electric range development - sammy1

Called in at Exeter Services M5 at 11.00 am. Services reasonably busy and only 2 cars waiting for a charger. More chargers being installed and the bank of Tesla chargers was only 50% 0ccupied. Various reports in press re stalled take up of EVs and another survey says 88 % would not consider one. The charger availability and range are a problem and the cost. Second hand EVs are said to be depreciating faster than ICE so they might be a good long term buy for the private owner How the cost of the fuel for EVs will pan out is anyones guess. Having never charged an EV is the "pump" price displayed or are buyers happy to pay. Hardly seems competitive for the consumer

‘ Having never charged an EV is the "pump" price displayed or are buyers happy to pay. Hardly seems competitive for the consumer’

No price totems for EV drivers displaying price per kW/h. All the info is on something like ZapMap as an app.

You may also find that car manufacturers supply a charge card with the car, offering a discounted rate with different charge suppliers. For example, a Plugsurfing card supplied with a Polestar will bring down the cost of charging from 74p per kWh to 35p at IONITY chargers.

Company car drivers who’ve traditionally had an Allstar (or similar) card for petrol or diesel may now have an Allstar card for public charging which may cost less than the full retail price.

So there’s a good chunk of people on public rapid chargers not paying full price.

I will give it another try in a few years time, until then petrol or petrol hybrid.

Surely that is only the case if you regularly do long journeys and/or can't charge at home. If you can charge at home and don't do long journeys, an electric car would be much easier and much more convenient.

Re charging times, the Hyundai Ionic 6 I mentioned earlier will charge from 10-80% in as little as 18 minutes on a 220kW ultra fast charger.

But you do have 'super' with the fast-charge dc pumps and 'normal' with the ac ones. The dc electrons seem to make the car drive more smoothly, as well as giving extra power.

The property manager for my housing estate recently has got (presumably leased) a BMW EV and he regularly tops up FOC at a service stop on the way from his home to his various sites (it might be by buying something there).

Given the recent press about the number of freebie charging stations / 'deals' dropping like a stone and charging prices going up a lot, it seems like a reality check for EV ownership is now on its way.

Given the issues with charging points not working and often never seemingly being fixed, you have to wonder when the sudden increase in EV ownership during the Pandemic times may have a detrimental impact on sales of new ones via word of mouth of bad experiences.

I remember driving around trying to find fuel when we had the fuel protests 23 years ago, but at least then the equipment was all working and it only took 5-10 mins to fill up and pay, and rarely did I get near empty.

Electric range development - Terry W

No surprise the freebie charging is on ots way out - there are now too many EVs to make it a business proposition.

EV charging at home costs 34p KWh. A typical EV does 3-4 miles per KWh - an average cost per mile of 8-12p. Cost of charging could be close to zero if charging at home with installed PV. No tax on electricity (at present) vs duty on fossil fuels (unfair?)

Cost per gallon is currently ~ £6.50. At a typical 40 mpg the cost per mile is _16p. Few people have their own oil well and refinery to reduce the cost further.

That there are still charging issues and range anxiety for some does not condemn the EV to long term to failure.

In the early 20th C no doubt there would have been similar concerns raised about ICE - the former unreliable, no fuel network, limited range, rubbish roads etc vs well proven steam and equine transport.

Electric range development - bathtub tom

I'm sure I posted this before, but when I was at tescbourys, a breakdown truck pulled up and dropped off an EV at the the free charging station. Would the supermarket have been willing to provide me with a litre or two of free fuel?

Electric range development - Andrew-T

In the early 20th C no doubt there would have been similar concerns raised about ICE - the former unreliable, no fuel network, limited range, rubbish roads etc vs well proven steam and equine transport.

But in the early 20th C very few people could even consider owning a car (and a chauffeur), and no-one commuted many miles to work except by bus or train, or walked, or possibly cycled.

Electric range development - Terry W

To judge from many contributors to this forum "very few people could even consider owning an EV".

The concerns are not dissimilar to a century earlier despite technology and society evolving - price, reliability, they burst into flames without the slightest provocation, no where to fill up and takes too long anyway, expensive to repair when they inevitably fail etc.

Much better to stick with what we know works.

Electric range development - Andrew-T

To judge from many contributors to this forum "very few people could even consider owning an EV"..

I disagree. From the responses it is clear that quite a few have 'considered' an EV and decided against, for the reasons you mention. A century ago owning a car (and chaufeur) was closer to owning a private jet, or possibly a Lambo.

So a typical low mileage driver (SWMBO, 6,000miles p.a.) spends an extra circa 8 x 60 = c. £500 on energy per annum. To recoup the extra £10,000 needed to buy an EV, that's 20yrs! Doesn't make financial sense for many pensioners!

They are 350kg items because they need the range. If swapping batteries via a dense infrastucture, which already exists here, you wouldn't need the range.

If wee Taiwanese girlies can swap one or two (depending on the model) scooter batteries in 20 seconds or so, they could swap 4 or 8 in a minute or two.

All the other jive above is also about existing electric cars, which rather obviously would not apply in this scenario.

OF COURSE any such car (I'm thinking a Smart sized beach-buggy/Mini Moke type thing with battery cell slots in the side sills) would have to be designed around the standardised Gogoro battery.

Taiwan has a standardized infrastructure simply by chance, because one company was able to dominate this small market. It’s still a proprietary closed system though, and it might take legislation to open it up

The old tech, lack of conditioning and lack of cooling seems to be reducing Leaf battery capacity significantly - BUT - this reduction rate isn't reflected in other designs and shouldn't be taken as examples for EVs in general.

Some older Leafs now have usable battery capacity less than some hybrids!

You can use up a LOT of energy keeping warm.. or cold.

Electric range development - Brit_in_Germany

Shame the edit button was missing.

If you imagine sitting in a car with a 1kW heater, you would rightly consider that would be too much heat but even sweating away for 6 hours would only cost you 10% of the range of an average EV. Heating, and indeed cooling, is an issue but not a major one.

Electric range development - mcb100
Even more (or less) so if you’re drawing heat from the battery via a low power consumption heat pump.

Now running an ICE to keep you warm, that does use a lot of wasted energy.

EVs seem to be at their most efficient in traffic, particularly if they are in regen mode.

It's high speed motorways at a consistent speed which seems to hit efficiency (although many still seem to do 3-4 m/kWh once warmed up)

Having a chat with my old neighbour who is the head technician at a Nissan & Renault/Dacia dealership, he has been told Nissan/Renault will never made a leaf/zoe with a range over 300 miles; any new battery development of range will be pushed to the larger vehicles.
Sort of makes sense

On a side note he has a number of new Mercedes Citans in his yard awaiting parts backlog; something to do with Mercedes not updating their internal software for parts ordering and Merc dealers are sending customers to Renault to speed things up (the Citan is a re-badged Kangoo).

It may be that a choice needs to be made by the manufacturer - more range or lighter weight, more passenger/load space and lower cost.

Most Leaf and Zoe owners would typically be local and low to average mileage drivers with few long trips. Taken with the probability of both faster and increased numbers of charging points in the future, the decision makes a lot of sense.
