EV general discussion

indeed. I love having an EV and hope never go back to an oil burner again (unless it's a Weekender midlife crisis car) but without home, work or local overnight roadside charging it's a way harder sell imo.
adding to the massive expense (public EV charging is more than petrol or diesel) it's only gonna add insult to injury when the government kindly add another 3p a mile onto your driving to make it even more expensive .

Agreed, there's absolutely no way I'd consider an EV without cheap low effort charging, e.g. at home or work (without having to fight for a space).

My mum & stepdad have been driving Teslas for years with no home charging and they do mega mileage - I have no idea how they cope to be honest, although with that said, both their cars are old enough to be eligible for the free supercharging for life, so I guess that goes some way to alleviating the pain!

Weird thing I noticed on the ID. 4

Plugged into a public charger today at 18%

It went down to 12% and now back to 20% having been charging for a little bit.


Any ideas why it would do that?


When I plugged in it suggested 44 miles of range, dropped to 35 as it started charging and now at 50.


Can’t say I’ve noticed a car do that before

Although I've not seen that big a difference, I've had similar with my id7. When I plug in at home the battery percentage often drops 1-3%.

I'm sure I posted something about it a year ago but on a couple of occasions I've noticed my battery percentage increase between stops. I've drove to work and arrived with x% and when I've got in the car to drive home the percentage has increased 2%.
 
I imagine it's software related rather than the battery state of charge actually fluctuating, especially given VAG are known to have various software issues with their EVs.

I've only had it once where I've seen the battery % increase and that's on the long, downhill section of the M62 approaching Milnrow. I've occasionally seen the battery increase by 1% whilst coasting down that stretch.

Think you answered your own question there.

It's free. It's Tesla.
 
The only real issue I've found with relying on public chargers was during winter when my charging speeds plummeted because the battery didn't have enough time to warm up first. That was frustrating at first, but just meant I'd put it on charge more often when possible just to top it up, rather than letting it run down more like I would when it's warmer. Fortunately it was a fairly mild winter up here so it wasn't much hassle.
 
Well, the Renault 5 Iconic+ is set for delivery on Friday 10th April. Can finally send the Clio back. God knows what the charges are going to be like on that as it's a shed on wheels with the wife driving it......

Little and often is usually the rule of thumb anyways especially for the higher density / longer range NMC. So I go to about 50% and top back up to 90%. Avoid deep discharges and avoid sitting at 100% unless it is going to be driven. For LFP I think regular charging to 100% is required and deep discharges are less harmful vs NMC.

Occasional charging to 100% (one every 2-3 months) is recommended in any EV. This is to balance the cells and give more accurate readings.

Yes good point. But not for battery health as per my comment this is, as you say, good for range recalibration and accuracy. But worth mentioning thanks! So charge to 100% occasionaly and then use the car, don't let it sit at 100%.

Yep, I hadn’t charged my Born 77kWh to 100% for about 6 months. When I finally did the GoM and efficiency readings went a bit nuts. It lost 11% SoC in 14 miles and I charged it back to 100% before ot started behaving.

It's the least with Tesla.

Big range, fast charging. Best Infrastructure, best software.

Again, while true, it's still not insignificant - their nearest supercharger is 20 miles away, so it's not like they can just drop it off and walk round the corner to get home, they have to either make a special trip to charge, or add 30-40 minutes to any longish journey

How often is occasional, I ask because we rarely go on long runs, mostly the maximum is our run to Peterborough of some 30 miles or so, thus I usually charge to 80%. I don't let the get much below 30-40% either in case the car is needed for an emergency.
Is every 6 months sufficient?

Bigger charges work better for me as it means I can get the most out of a couple of cheap(er) charging options I have nearby. It's really only in the colder months that I'd be using the more expensive chargers at retail parks or Sainsbury's just to top it up while I'm grabbing some shopping. Would much rather charge at 49p/kWh than 72p. :)
