Better get mine now then.

Finally my Kia e Niro, fully electric car has arrived after almost 10 months wait
So far so good, lovely and smooth AND very fast when pressed

First full charge and the car is predicting 291 miles to my 64kw battery charge

I will have to Wait and see

Ok so how is it going, any updates, good/bad/indifferent?

Any issues in the cooler weather or for that with aircon when was warm?

Any range anxiety?

????

Had a model 3 since August, previously had a focus ST. Took a lot of getting used to as the ride and drive is massively different. I miss the engine note and the sensory feeling of the ST. The model 3 is nice to drive and is quick, I’ve only got one due to the tax I can save (currently) sure this will change as more and more people get EV’s. Found out yesterday that the range changes a lot when it’s cold and the car has completed a software update over night .
Jury is still out but so far so good. If I had to do it again I would have paid the extra and gone for the long range version. Only another 3 years and 8 months of driving to go!

Depending on the car and on if you do the preheat thing while still on charge.

We don't preheat our EV as it only takes 5 mins to clear the windows when frosty as it was yesterday morning but all EVS suffer range loss in winter even a tesla.
And if anybody has an EV and home charges check out octopus go tariff or if you are adventurous octopus agile.

What are you running please.

Jaguar I pace, love it, goes like stink.

I don't dispute all lose range. I do however dispute the 40% figure at least with respect to Tesla if used correctly. The 40% figure is based on -6°C test with no pre-heat and the test is not based on a full use of the battery.

For example. If you start your trip with 300 mile range in a cold car, then the initial heating pulls a lot of current from the battery but once it has reached running temp this drain is reduced a lot as it only has to maintain the cab temp.
The same goes for the battery, without pre-heating the 1st bit of the drive will draw more capacity from the battery as the internal resistance is higher when cold. But as the battery warms up (in cars with active thermal management) the current draw per mile returns to normal although the initial miles will have had a greater impact on the battery than norm.

So if your test runs for only 50 miles and either calculates the mileage based on those 50 miles of usage or the displayed estimated range they could be a lot lower than the reality.

Here is the thing though. The Model 3 can preheat both the battery, the motor and the cab area whilst still on charge before setting off. At this point there is little if any temperature related degradation in range.

I believe 2 or maybe 3 other manufacturers have systems in place that do this as well. But the superbottle setup in the 3 and the new heatpump and octo valve in the Y make a huge difference to efficiency of this. The heatpump and octovalve are being fitted on new model 3's now as I understand it.

The Jaguar iPace also allows you to "precondition" the battery in winter, but it requires the battery to be charged to 100% to do so. So you lose the range impact of the cold weather, however due to charging to 100% you will reduce the lifespan of the batteries.

The Audi E-Tron doesn't appear to have any heating connected to the coolant system and requires the motor to be running to generate heat for the battery loop. I wasn't able to find any hard details on this.

The Kona doesn't appear to have the ability to pre-heat the battery but is linked into the coolant system so can pull heat from the motor.

The Nissan leaf has no active thermal management at all and will suffer badly in cold weather.

Update
Car is fantastic, smooth, comfortable, fast when you want it
The range HAS dropped on the very cold days recently
In summer, 4.2 miles per Kw was normally achievable, which is good by EV current( no pun) standards

Short drives down to 3.4 miles /kw , so down 15%ish, but settles at 3.8
Much milder today and done 45 miles today @4.0

I charge at work, but still miles cheaper than petrol/diesel AND my personal tax saving
Company bought it, so not tied into a deal
So far so very good

 

[Cheshirecat57]

Cheshirecat57 may I ask how you are getting on now a few months have passed?
Any words of wisdom or opinion now the initial shine has started to dull!

Hi
Zero dulling of initial shine
On the contrary, 5 months in and I love it more

Im a fan of the brand though TBH
Just swapped my wife’s MINI for a fully loaded Picanto !

(On a separate note, I can help anyone get a good deal on any new Kia if you PM me)

The I pace will not charge to 100%, although it shows as 100% the charging system will only charge to about 95% to protect the battery.

All that tells me is you got 10 mile EV range and the rest is child choking dinosaur juice.
i take its a plug in hybrid? drive it untill the EV range has gone then watch the MPG rate drop.

No EV will charge to 100% of battery capacity, only to 100% of rated capacity. They all keep a bit in reserve.

But the higher the charge the more you affect longevity of the battery which is why most EV manufacturers recommend 80% for day to day use only charging to 100% prior to long journeys.

The ipace will Never charge to 100% the systems are set up to preserve the battery, the tesla way is to charge to a lower figure normally but with the ability to charge to 100% when required.

Not correct. Tesla do the same thing. All manufacturers do. They over provision battery capacity so as cells lose capacity the usable capacity is maintained. This is standard practice across all manufactures even the Nissan leaf over provisions.

What is not correct?
With tesla you set the level of charge, ipace will by default charge to "100%" which is never actually 100% whereas tesla can for long trips.

When you charge a Tesla to 100% you are not charging it to 100% of the real battery capacity only 100% of the available battery capacity. Telsa like all other manufacturers over provision

EV makers must further account for capacity fade in a clever and non-alarming way to the motorist. This is solved by oversizing the battery and only showing the driving range. A new battery is typically charged to 80 percent and discharged to 30 percent. As the battery fades, the bandwidth may expand to keep the same driving range. Once the full capacity range is needed, the entire cycle is applied. This will cause stress to the aging battery and shorten the driving ranges visibly. Figure 5 illustrates three SoH ranges of an EV fuel gauge.

Figure 5: Driving range as a function of battery performance. A new EV battery only charges to about 80% and discharges to 30%. As the battery ages, more of the usable battery bandwidth is demanded, which will result in increased stress and enhanced aging.

Tesla do exactly the same. Except they go a step further and recommend you only charge to 80% of the "virtual" battery extending the lifespan even further.

PS: My point was that battery conditioning only starts once you hit 100% in an ipace so you can't keep your battery at 80% of stated charge and pre-heat the battery. The Tesla allows you to pre-heat the battery not matter the state of charge. This also helps with regen braking.
