EV general discussion

[tamzzy]

What's the average miles/kWh you guys are getting in your EVs?

4 in summer, closer to three in winter

This is what I used when I did my calcs too
(and also depends on what EV you are looking at, the older ones are going to be less efficient ofc)

In reality, at least for the 2 months 900 miles I've owned my 2022 Model 3, I've averaged 4.7m/kwh in city traffic, 4.2m/kwh in motorway traffic (and I definitely don't drive like a grandad )

What's the average miles/kWh you guys are getting in your EVs? Just doing some maths for a friend. I've been working on the assumption it's around 4mi/kWh but reading around it seems that that is optimistic.

You'll see a bit more seasonal dependence on mi/kWh than people typically noticed with mpg but it's also very much down to the car and the driving style, just as it ever was so that needs to be the starting point of any maths - are they aiming to buy an old model fat e-tron that's notorious for poor efficiency and sit at 80mph on the motorway with it or something more efficient like the latest Tesla Model 3 range and drive it gently everywhere? You'll be looking at anywhere from 2.5mi/kWh to 5mi/kWh.

If they have no idea, then 3mi/kWh is probably safer 'year round average' to use than 4mi/kWh to understand potential running costs.

Tesla definitely have the edge in efficiency - in the end though I’ve found them to be so cheap to run and had no issues with range that I don’t feel I have to worry about that figure in particular.

this is absolutely true!

 

[ICDP]

Yeah, I remember being told my I-Pace had terrible efficiency. Not compared to a similar combustion engine SUV. I was getting over 100mpg

 

[Haggisman]

3.8mi/kWh over ~8k/12 months with a mix of long motorway journeys and shorter local trips (probably 70/30 in favour of the local trips).

That's in a 2020 e-Niro

Thanks guys.
She's looking at a Kia Niro EV. The problem is that she has nowhere to charge it at home (flat with communal parking about 100 metres from the building), or at work. She will have to use public chargers.
I'm just working out her cost per mile and assuming around 70p/kWh and 3mi/kWh she's looking at around 23p/mile in electricity costs. That's only 3p/mile less than my Mustang costs me in petrol with its **** off V8 engine.
Just trying to convince her that buying an EV is not a sensible plan for her if the goal is to save money on fuel.

3.5-4.5 in summer.

2.2-3.0 in winter.

Cupra Tavascan. Though note that I don’t really drive economically and only really pay attention to the efficiency on long journeys when I know im pushing it.

yeah, no home or office charging = not worth it.
charging can be anywhere between 54p to 85p/kwh (cheaper at tesla superchargers)

if the overall vehicle cost is the same, it may be worth considering a tesla instead as you then get access to supercharging at cost price (24-37p/kwh) rather than paying the exorbitant public charging prices

So why are you using the 70p kWh at the benchmark? Have you looked what public chargers are near where you live or the places she goes that she would charge to see if the cost is actually 70p, Electroverse offer discounted charging and have plunge pricing offers on lots of days/time, and some companies off a monthly pass that lowers all the kWh pricing.. Have you looked at communal charging (ZapHome, Co Charge, JustCharge)?

How much cheaper is the equivalent ICE car vs the EV regardless of the cost per mile?

EDIT: Tesla membership £9.99 per month, most chargers are ~25ppkWh or just over for that. I mean if she is only doing 200 miles a month probably not worth it.

 

[tom_e]

It's not just the cost, even if you can get the numbers to work it's the pain of having to rely on public chargers working/being available/being close by.

I did it for a couple of weeks and having to add 30-40 minutes to my office days to sit at a supercharger first thing in the morning was doable but I absolutely would not want to have to do it as my only way to charge long term.

Few things to consider in your calculations, if you get an electroverse card that can reduce charge costs by a few p per Kw. If you have any open to all Tesla superchargers close that will about the 44p ish a Kwh, so nearly half the cost. Some charging networks such as Ionity have a subscription (or annual fee), think theres is £10.50 a month or £85 a year and reduces the rate to 44p a kw or around 10-15p a Kw/mile.

 

[Diddums]

Oh my.

Also depends on how many miles she does a year? As others have said can definitely get cheaper public and most offer some sort of subscription for discounted rates too

But yeah without home charging it can be a pita.

Unlike what you read in negative press stories, it is possible to run an EV on public charging cheaper then fossil fuel.

Other methods include AC charging when doing supermarket runs, at the gym, walking, meeting friends for socialising etc. AC costs are a lot cheaper than DC and can easily be fitted in to a normal routine, or you just slightly change your routine around charging.

For example I started going to a different dog friendly park that had AC chargers nearby. A 45 - 60 minute dog walk even 3 days a week at 11kWh would enough for 30% - 50% of a 64kWh battery.

It is possible, but it can be a massive inconvenience - if (and it's a big if) it fits your routine without too much change then maybe it can work, but given that 2 of the biggest positives to EV ownerships are the reduced running costs and convenience of just being able to plug in at home and wake up to a full car, I wouldn't recommend it with no home (or workplace) charging unless there was another specific reason that an EV would be a significantly better option than an ICE.

That makes things a lot better but it's still going to be more expensive than getting a small petrol engined car that does 40 to 50mpg. Her weekly milage is about 200 miles.
TBH, I think she will get the Niro anyway no matter what anyone says. Her dad has a Tesla and is a very long way down the 'ICE cars are obsolete and you'd be a fool to buy anything other than an EV' rabbit hole. He can of course charge at home and has access to the Superchargers. Maybe I can convice her to ask her dad to buy her a Tesla.

 

[Demon]

Oh my.

Wow..

That looks insane, large battery, decent enough range, 555BHP, RWD and the wide body?

*chefs kiss*

Tell her to just charge at her Dad’s house instead.

 

[Yaayuh!]

Note to self: Pay attention to the update details before applying. Might save 40 minutes of sitting in a Tesco car park like a moron.
