Oh that Lexus looks terrible.  Well - not bad, especially, but not special. Looks like it should be a Mazda not a prestige manufacturer.

On the subject of subjectivity, most of us on here hate the Ioniq 6, along with most of my workmates; but today my neighbour (who is into cars) said "I saw one of those Ioniq 6s the other day, looked amazing!"

Oh great, more clickbait videos from anti-EV YouTubers 😀

You want “connected” cars that you can control with an app and that can perform software updates without you having to take them back to the dealer? That means the manufacturer can control them too. Got nothing to do with whether they are EVs or not.

My Enyaq iv arrives on Tuesday - am I needing the Skoda app to make it all work? If so, which Skoda app as there appears to be 2 or 3 (and they all get terrible reviews)...

Got Zap-map, but needing to actually look at it properly as I still haven't gotten round to working how to to charge the car...do I need to join a card scheme to get cheaper charging rates or is it just a case of looking around for the cheapest charge rate near me (central Scotland)?

Aware I've had this on order for over a year, but just realised I've not paid it any real attention until now...so needing to do some research over the weekend! Ordered it knowing it was going to be ages before it arrived and then forgotten about doing any of the finding out bits...idiot!

Only if you're using public charging a lot. Otherwise it's not worth it, just beep your debit card and plug in.  Do you not have a home charger?

I joined ChargePlace Scotland last summer when I got my EV.  I haven't used it yet, with the only public charging so far having been on the rapid Tesla ones on the A1 near Bamburgh.

yep, not all obviously , but the ones that have an app that you can use to view the status of the car, lock/unlock it etc could all feasibly be disabled remotely if desired and designed with that intent in mind.

Its not limited to cars, Its just the (potential) nature of any internet connected device,not just cars, if the vendor wants to , they can remotely break it/disable it/limit it.

No option for a home charger as car is parked on the road...I'm hoping I can grab a space at work as the charging is either free or very cheap, so if that works, I don't need to worry too much about the public charging, but would be good to make sure I'm not a complete luddite when I come to use it first time round. Aware I should have been doing this much sooner than 4 days before the kit arrives!

I'll avoid the Skoda app as I suspect it is an extra rather than a requirement...will now spend some time trying to work out how Zap-map works...

Next daft question - for my thick maths in my head...the Enyaq is a 62Kwh DC120kW battery - is that the capacity of the battery - and is is 62 or 120? I'm guessing one of those numbers is the battery capacity so it I was to charge from absolute zero in the battery, then the per Kw charge would be whatever that is times the amount of the battery capacity - yes? Is it as simple as that? (I'm absolutely convinced I ordered this whilst hypo as I appear to have ticked some options and now wondering what I've picked and why!!! Looking forward to it but now thinking it wasn't properly thought out!)

62 kWh is the capacity of the battery, like gallons or litres.

120 kW is the max DC charging rate. i.e  If the battery charged at 62 kW it would take an hour to charge.

Bear in mind that the 120kw speed is just a peak on a charging curve.  It will not charge at that rate the whole time it’s plugged in. The Fastned website will show the charging curve for your car.

Don't give up just yet.  Some councils are making it easy for you to run a cable across the pavement. I think you always need a permit from the council - some are handing the permits out to EV owners automatically, I think. Give them a ring. What council are you in?

The apps from Skoda are probably there to allow you to start warming or cooling the car remotely, or lock it - which is dead handy.

the Enyaq is a 62Kwh DC120kW battery

Science lesson:  kW is kilowatts which is power, like horsepower. It means how fast your car can accelerate. kWh is kilowatt-hours, which is a quantity of energy so 120kWh is the amount of energy you'd get through using 120kW for an hour, or 60kW for two hours etc.  In theory, you could recharge your car at its max of 135kW and get the battery filled in half an hour - in practice this isn't the case as some is lost and they slow down as they start to pass 50 or 60% full.

This is how the 60kwh car from 2022 charges, but I think the new model is a bit different.

You want to look for the 10-80% charge time, which is often quoted. Seems to be 35 mins for your car.

62kWh is the 'fuel tank size'.

So to fully charge at, say, 10p per kWh, it'll be £6.20...

DC 120 is probably the max charging speed.

Thanks very much for this info - both @perchypanther and @molgrips...so my thinking wasn't that far off and it means as long as I'm not running it flat, then I should be about £20 to charge up (depending on how much charge and cost per kW) - that was what I was thinking it would be around and it appears I'm not too far off that.

Cost of public charging varies wildly.

anywhere from Free to 80p per kWh

So it might cost you pennies or it might be up to £50

But yeah at normal domestic tariffs about £20

@DickBarton one watch out,  some charge place scotland sites are ac charging only, so slower to charge. AC uses the onboard car charger, 11kw for your car, so if you use a 22kw AC charger it will only charge at 11kw speed. This is one reason most home chargers are 7kw as they use AC. The 120kw rate for your car is the fasted DC charge it can take.

Public charging is sodding expensive. Expect to pay 50p per kWh for a 7kW AC charge (which will take you many hours) and around 80p for rapid 150kW charging.  Compare this to 7.5p for home charging if you get a cheap EV tariff.

Picked up my Model Y RWD co. car on Thursday.

Last two journeys have been up and down the A2 with varying speeds between 55 and 70 ( probably tending more towards early 60’s) and over 18 miles I’ve been using 185 wh/mile or 5.4 mpkwh. A similar journey in my previous car, Merc A250e would have given 4 mpkwh at most, so I’m impressed.

I think yesterday and Thursday were ideal BEV temperatures though. Not cold and not warm enough for cabin cooling.
I have a 350 mile round trip to Nottingham coming up soon, so will be interesting to see how I get on.

Good start though. I’m impressed with those figures.

The last couple of times I’ve done some motorway driving, over to Caldicot and back, the one thing that’s really struck me was that all the EV’s, from Nissan Leaf up to s****y BMW’s, Tesla’s, etc, were sitting at 70 or less, one very sporty looking Beemer was doing about 60, because I cruised past all of them at around 75.
Why would that be? Afraid of running out of juice ten miles shy of the next charging station?
Yes, I can tell EV’s from ICE’s.

Afraid of running out of juice

Not exactly.  There is a difference between “afraid of running out of juice” and “slowing down a bit to improve range”.

There is also a “don’t need to prove anything” aspect to this.  Having a car that can easily out accelerate almost any ICE car especially in a rolling situation there’s no perceived need to prove anything.  Look at the number of fast ICE cars you see bumbling along as an example - plenty of fast Imprezas, Porsches etc also at 60/-65 ish.

It's also possible that they're using adaptive cruise control and haven't noticed that they've slowed down..it's not obvious when you don't hear the engine note drop. Just goes to show how unimportant speed is.

EVs are also nice places to be whilst cruising - a combination of the lack of engine droning away and easy power delivery means that it’s quite a bit more pleasant a place to be - chilling and listening to music, podcasts etc so bimbling along is more appealing. There is little difference in perceived speed to the driver. Also - once you’ve tried the “slowing down to 60/65 ish” approach you realise that (a) it does affect the actual journey time much at all and (b) it’s far less stressful than the perpetual faster / slower / stuck behind slowcoaches in the fast lane / speed off / get stuck behind the next one etc
Etc. after a while it becomes clear that’s it’s a nicer way to travel. See also my previous “nothing to prove” comment - the opposite of the tiny, beat up old cars doing what must be close to their top speed in their fast lane that must be somewhere between noisy and uncomfortable and terrifying

My Audi Q4 eTron was due 31st May. Got a phone call on Wednesday to say it’s now ready and will be delivered on Wednesday 27th March!! I haven’t installed the home changing kit yet.

Ive opted for a tethered Ohme and gone with Octopus Intelligent. Two week install time so I’ll need to charge using public chargers for the first week.

I’m also heading over to Anglesey for Easter, going to be interesting to see what the charging is like there. It’ll be at the in-laws overnight so I presume I can just plug into a 3 pin socket from the garage and charge it overnight. Any idea on rough cost for this? Father in law was an accountant and still counts every penny! He won’t be on any ev related tariff and the Q4 is 82kwh battery. So 10 hours plugged in to a non ev rate socket? Also roughly what % of the battery would 10 hours on a standard 3 pin socket return?

27p per kw on a regular tarrif.

3 pin plug will give you 2.3kw per hour

Does the car come with a 3 pin plug charger?

I think a 3 pin charges at 3kwh? So if his tariff is a pretty standard one at around 30p per kwh then I would estimate about £1 per hour of charging? At 4 miles per kwh thar gives you 120miles top up for your 10hrs

Thanks guys. No, the Audi doesn’t come with the 3pin as standard. I assumed I need to buy one of these?

https://ev-extras.com/products/audi-q4-e-tron-ev-portable-charger-uk-3-pin-plug-5-7-or-10-metres

I’ve also been looking at public charging prices on ZapMap, damn expensive! 75p pKWh seems to be an average. Not that I’ll do a full charge, but that is £60. Exactly the same as I pay for my petrol car now but 150 miles less. I take it most people only use public charging when they really have to!??

Yes, I can tell EV’s from ICE’s."

When I had the i3, the range wasn't enough for an occasional journey I made. But stopping to charge would make the trip cost £50 rather than £8, without making it any quicker. So hypermiling made sense.

Wierdly, the Polestar seems to have less differential between 60 and 80. But I have discovered that it's much more relaxing in lanes 1 and 2 than avoiding the odd **** in lane 3.

True. We generally drop  our average speed on the larger roads when we are doing longer journeys, but the route planning generally takes into account charging places where we can stop overnight. Fast chargers are ok (you get to take a break), but it's very much not as cheap as home charging and not good for the battery.

On a side note, I miss having the Niro when I am out in the van. The van is not loud to drive as such, but the Niro is so much more quiet and the power and torque is so much more friendly, I miss it. It got me thinking about roughly when EV vans will start coming onto the market second or third hand and when/if people will buy them to make day vans with. Will they even bother?

I reckon until the range is massively improved then vans aren't going to be that popular second or third hand in most cases...

I don't see long range vans being economically viable in the near future. The shape and size is inherently inefficient, you'd probably need a 150kwh+ battery to get a half decent range (the hummer has a 250kwh battery to deliver a 300 mile range).

Most companies buying new will just look at the total cost over 3 years, for short range (deliveries etc) an EV will make sense (additional purchasing cost offset by cheaper fueling/maintenance), but with an extra 75kwh of battery costing an extra £10k, I just don't see it working out. You don't want to be paying a driver to be sitting round for a couple of hours waiting for it to charge up either

@DickBarton, I think lots of the hospital charge points are only A/C charging (I think larbert is anyway) so dispite saying it’s a 22kw charger it will only charge at the cars onboard 11kw so you will not get much range for your half hour (and you may have to pay a connection charge too). Fine if you are visiting there and just topping up but not that great to use regularly for a decent charge. If you look on Zapmap for charge place Scotland and just select D/C chargers there are not as many choices.  Our local town has a 22kw but it’s only A/C so I will go to the next town that has a 50kw D/C when I need to charge locally.

I’ve really enjoyed our i3 and so have decided to replace it with another one.  This time a 42kWh version.  Really impressed with it.  It seems much more refined than our old car and the efficiency is REALLY impressive.  It’s only a 37.6kWh usable capacity and we’re getting between 180 and 200 miles on a charge, so between 4.8 and 5.3m/kWh.

Thanks @andy4d, I'm a 10-minute walk from there so unless there is a lot of demand, it wouldn't be an issue if it was parked for a couple of hours...I'm hoping everyone new to everyone has the same daft questions and it isn't just me being a complete idiot (who didn't do any sensible research before ordering!).

Rapid charging isn't a big deal on a modern car.  Especially one that cools or heats the battery.

My neighbour has just got a Q4 e-tron as a company car, he has no idea about charging at all even though he has a home charger that probably came with the car. He didn't know you could get cheap overnight electricity despite being with Octopus already.  He said he wouldn't want to take his car any further than Bristol (about 45 miles away) despite it having a 300 mile range. I think he's leaving it go to empty before charging, which means he's setting off with low percentages and hence worrying about range.

So, after seeing that Lexus deal earlier in the week (posted earlier ^^^^), I decided to order one (delivery won’t be until September when my current lease deal expires).

It’s my first electric and I know nothing about them so I have questions (granted I have plenty of time to get to grips with it all).

I have a drive so I can charge from home - are all chargers equal or are there some that are better than others?

My current tariff is 21.33p KWh (fixed until next March). Would I be better off paying early exit fees to switch to EDFs electric car tariff (we do around 8k a year).

Is there anything else I need to know?

Well, your basic cheap overnight tariff with Octopus is called Octopus Go and is 9p/kWh; but you can get 7.5p over a longer period overnight AND any time of the day when you schedule it* with, Intelligent Octopus Go. For this you need a car that supports smart charging OR a charger that does.  Octopus support Ohme and Zappi. I've got Ohme and I can't see any reason not to get one, especially as Octopus give you a bit of a discount on them.

You can do the maths yourself to decide if it's worth it - the current day rate for Intelligent Octopus Go for me is 29p - but factor in that you may be able to schedule your washing machine/dishwasher/water heater overnight and save more that way.

* What this means is that you tell it how much charge you want by what time, and it will ensure it's ready for you. This works at any time of day or night.  The only time you have to pay full whack for your power is if you plug in and select instant charging.  On top of that the overnight period 11.30pm - 5.30am is always at the low rate, for your whole house.

Question for the e car people

How often do you plug your car in to charge?

Every day regardless, or do you wait until you drain it to a certain point then plug it in?

We plug ours in when it gets to about 30% charge, and plug in on a Friday night regardless of state of charge just because we don't know what we might need over the weekend.

How often do you plug your car in to charge?

In a normal week, twice.
Tuesday morning for 3-4- hours and Friday afternoon for 3-4  hours. Charge at work almost exclusively and those times suit my schedule. Add about 40% charge each time.

I charge mine daily to 80%. I use about 25% a day and top it up by 20%each night as my cheap tariff is for 2hrs. On my days off when I don't use the car I still charge it to make up the shortfall and make the most of the cheap rates.

I plug it whenever it's home (unless I know I'm going in and out a lot), which is what Octopus recommend. They want to be able to stick a bit of spare energy in your car whenever it's available - that's why they offer it cheaply.  With an Ohme charger, we set a schedule in the charter that says we leave at 7.30am or whatever each weekday.  Ohme will also turn on the heating/AC/defrost etc at that time.

@andylc I am in Ireland. I get 35c standard rate, 17c 11pm to 8am with 2am to 4am just 10c so I set it to charge 2am to 4am every night and only charge outside that if needed for a long trip etc.

‘How often do you plug your car in to charge?’

When it gets to around 50% at home, and on IO it starts sometime in the evening with a ‘100% ready by 0700’ command in the Octopus App.

It 6 months into a 4 yr leave so I’m not expecting any issues charging to 100% in the time I have the car. It is used daily, generally short miles. Today it’s done around 70 miles and good to see it back up at 4m/kWh now the weather is warmer. (BMW i4 40)

Full EV car get plugged in when it gets to about 30% or so. 4 hours cheap overnight at 7 kW gets it back up to c70/75%.  This is weekly or so.  If long journey then we just charge to 100%

New PHEV van - every other night - empty to full at 3.5kW charging takes 3.5 hours give or take. Get about 30 to 35 miles from a full charge if I'm careful.  Pretty much enough for two days -  mostly running on full electric so far, but it does need to run the petrol engine periodically so I'm not too zealous

Works perfectly. The regen braking is strong and means you hardly ever need to actually use the brake pedals at all. If you want to stop quicker then just use the pedal for additional braking. No need for blending, most of the time it’s one pedal driving.

That really sounds like a terrible design choice

Seems like a good choice to me*

-simpler braking system, less to go wrong

-cheaper to build the cars.

-more consistent pedal feel. I hate the pedal feel of blended braking & when it transitions from regen to friction in the cars I have driven.

-no less efficient than blended braking, as long as the user understands they should not need to use the brake pedal much.

*I'm not a tesla owner.

*as long as you can reduce the regen on throttle pedal lift off in some menu somewhere for when you want to 'press on' for better control/balance of the car.

Fine for techie types.  Most drivers don't care about any of that stuff and just want the car to work like they expect.

Out of three cars I've driven with regenerative braking you couldn't tell the difference so it's clearly possible.  Maybe Tesla need to go and ask Hyundai or Nissan to license some of their IP.

The issue i've had with tesla's one pedal driving is when it can't regen, it gives you a bit of a surprise by not slowing down when you lift off the gas!

To my mind the car should always act the same regardless of whether the battery is cold/too full etc.

It still regens when in this mode, just doesn’t slow down quite as much, the difference is noticeable but not major. Still slows the car down more than our Renault Zoe or my Dad’s Kia even when they’re in high regen mode.
Plus fairly predictable as only really happens if you go down a pretty long downhill stretch when you’re already close to your maximum chosen charge level.

Hyundai nailed that too apparently.

BMW have this sorted. My i4 is impossible to tell the difference between regen and friction brakes - if you didn’t know regen was a thing you would just think it’s normal brakes. plus you can change it between almost no regen through to full one pedal driving or my favourite, adaptive regen. Adaptive is good enough that it acts as a kind of mild adaptive cruise control too.

Once you’ve got your preference set up, you can swap between it and one pedal driving with one flick of the drive selector switch / I use adaptive 90% of the time but switch to one pedal for city centre stop start driving on when in stop start traffic jams on the motorway.

The blended braking on my A250E was crap. I was never sure what amount of braking I would get on pressing the pedal. Occasionally i could feel the abs kicking in, even though I wasn’t applying much force.

The one pedal braking in the Tesla is much more consistent from what I’ve experienced so far, although I’ve only charged it to 100% once.

"How often do you plug your car in to charge?"

My routine is to aim to plug in when the Agile Octopus price is right. Often that's during the night, but not always, most of Saturday day it was 0.00p/kwh and a short period during the day on Sunday it was -3.78p/kwh and -1.03p/kwh. If prices are high then I either won't plug in (if the car is full) or just charge enough to get to work (if empty). I pay £10 a year to get 1 week weather data and 48hr price predictions in convenient format. Also, usually weekends are a cheaper period, but mostly if it's windy, it's cheap.
If I'm going somewhere afar beyond routine/commuting/local then I'll just charge as best/cheap I can. At the end of the day charging at home is always significantly cheaper than public charging (outside 4-7pm in the case of Agile Octopus)

-simpler braking system, less to go wrong

Not really, tesla already have brake blending on regen in some models/softwares, so adding it to the brake pedal signal is relatively straightforward. If you've spent any time working out your architecture properly in the first place.

-more consistent pedal feel. I hate the pedal feel of blended braking & when it transitions from regen to friction in the cars I have driven.

Which cars have you driven where you can feel it? I worked in development of brake blending and have spent a lot of time driving cars with it installed, and very few are even noticeable, even if you are looking for it, and can see data logged info on a screen in front of you...

Curious about Agile Octopus - presumably this requires active monitoring and the ability to decide to charge at relatively random times??
Do you manage to get an overall advantage vs Intelligent Octopus? Over the last year for example my average unit price was about 14.5p.

Which cars have you driven where you can feel it? 

Mercedes and Toyota, there's a kind of click/step/notch in the brake pedal travel when braking hard where it switches from a mix of regen and friction to 100% friction. And the notch is at different points in the brake pedal travel depending on something that I can't determine, maybe it's the friction of the surface at the time, or maybe it's speed dependent or something.

Plus they've always felt wooden to me, but that not unique to regen brakes, plenty of normal brakes suffer that.

I know people who do the Agile Octopus thing but they're ubergeeks and have all sorts of home automation stuff. I could do that but I can't be bothered.

Re brake blending, in the Prius you could feel it roll off the regen and onto friction when slowing gently at low speeds just before you came to a stop, but it was barely perceptible. I noticed in the Leaf that the physical pedal was actually on a spring so when the car was off you could just boing the pedal. But it wasn't any different to a normal car in use. You couldn't stab the pedal that hard when driving without doing anything emergency stop. I read the other day that Hyundai have a secondary master cylinder that pressurises the one you feel under the pedal so you feel feedback. Seems to work but allegedly if you need it replacing it's expensive.

In the Model 3 at least there was an update a while back to blend in the friction brakes in high SoC to make the braking/regen consistent no matter what the state of charge. Must admit, I struggled to tell if it was working or not.

Re charging - i plug the car(s...have a LEAF too) in whenever it's at home. Not because we 'need' to keep teh car charged, but as we're on intelligent octopus Go, it 'forces' the whole house onto the cheaper tarriff (of 7.5p/kWh).

So not only is is super cheap electricity to charge the car, but to use the electric appliances too..

For example - IO has cheap hours something like 2330-0430, BUT if i plug the car in at 1657 today, it'll PROBABLY do a bit of thinking,adn offer cheap rate from, say,  1800-1845, 1900-2000, and 2030-0500...

Which is nice.

Ah, so not normal braking then. That'll probably be the delay between regen running out of steam, the friction brake request being generated, and then the rapid ramp up. Essentially pulling the pads in from "plenty clear" to "hitting the disc with a bit of force" in one step *while you are already decelerating hard*.

There are systems in place to mitigate against that, based on rate of pedal movement, move the pedal over a certain rate and it'll start pulling the friction brake request in earlier, so you shouldn't get the step change in brake force. Not sure who has that incorporated yet, as i'm not working in that team now.

There are also a few different versions of emergency brake boost, where the brake system will ramp up over and above the expected level if you hit the pedal "emergency stop" quickly. That can give you a click/step feeling.

There should be virtually no difference in feel as you switch to friction brakes, unless they are corroded or damaged.

I only charge fully three to four times a month but Intelligent Octopus works much better for me than Agile. Whenever the car gets a charging slot the house battery refills at the same time, so over the last six months my overall average unit price is 7.6p/kWh.

@andylc Yes requires active monitoring, I'm not sure it'd work for someone with a busy work/family life. Also might only work if you can shift house use outside 4-7pm and requires everyone in the house to buy in. It would definitely work if you have a battery/solar etc. I've only recently switched from the original Octopus TrackerV1 which was cheap enough to stick on, but now all the old version smart tariffs have been withdrawn by Octopus and everyone migrated onto the latest version, the new Tracker tariff (Dec23V1) is not as cheap. If Agile doesn't work or I don't save much for the extra work involved, then I'll switch to Go/Intelligent. I can't give you any total figures as I've not been on it very long, but purely car charging in March has been 274kwh @ 6.77p/kwh and more than likely the washer/dryer/oven have been used at those times as well. On Sunday morning when the price was -3.68p/kwh the car was charging, all the frozen pizzas in the fridge were put in the oven and the washer was on 😀 .
As Molgrips says, the geeks and sad people's tariff

where it switches from a mix of regen and friction to 100% friction

I don't think it would ever be 100% friction, would it? I'm not sure it would ditch regen altogether unless its a full on ABS firing emergency stop perhaps.
