EV general discussion

Proper noob question here but a hypothetical 13kWh charge covers a daily commute.

If that 13kWh was added back daily over 6 hours from a 3 Pin @ 10A what would the rough efficiency be compared to the same charge done over 2 hours from a proper 7kW charger?

Just looking for a ball park but, all other things being equal, would we be looking at a 1, 5, 10, 20% difference in efficiency between the two?

Not much in it 89 vs 92-93 %. A 3pin gives about 2.05kW into the battery

Its going to be low single digit percentage difference, the loss itself can be higher, I'm sure mine is as much as 14%.

No the loss is quite high generally but negligible between the two types of cable, single digit percentage at most if not just in the noise due to rounding, sorry for not being clear.

To be fair there's an amount of fudge in the loss as what's picked up by my Zappi and what is recorded by Octopus is less but if you are estimating costs it is probably better to go higher number rather than lower.

symonds video .. so independent extended battery warranties , let's have those for phev's too
jumped FUD - didn't seem to mention calender ageing impact on battery life .. but if the warranty is at least good for next owner on his 100K+ M3, it's a useful security

So by you own admission you watched less than 3 minutes of an 11 minute video but then decided post it here as some sort of value contribution?

Yeah nice one, thanks.
 
@lordrobs Not sure if you have the budget, but the new Kodiaq PHEV has a decent sized battery and a pretty reasonable 5% BIK.

I see the A6 etron is now available, i know list price is not the be all and end all in the lease/comp car markets, but it starts at ~70k :o Will be interesting to see the efficiency, its a got a 100kwh battery.

Damn, that would be good but with the trade in on the Leon I've got about £30k all in to play with so we are looking at about a year to 18 months old.

It's out of my hands now as I put forward my ideas, ideally I'd have got an Octavia Estate PHEV but there seems to be a gap in the used market with most being older than we'd like.

So it looks like I'll be getting a Sportage PHEV which was my second choice. 8% BIK and a decent boot is all I really care about. Not really a fan of SUVs but there was nothing else as tax friendly estate wise in budget (Merc CLA boot is too compromised unfortunately). If it drinks as much fuel as I fear it will then I'll pay back private mileage like I currently do @ 15p/mile.

Going to give it a decent crack with charging it up and driving economically first to see if it covers it's drink habit on work runs at the HMRC rate. Once we've found a car obviously...

For those who e had the same ev for 5+ years, what maintenance and servicing have you had to do?
Click to expand...
2019 Ionic PHEV annual service, changed wiper blades, tyres and replaced aux battery. Car ev range as good as when new. Charge from home using tethered podpoint.

I asked about ev not hybrid; reason being I want to know how much servicing people do. I hate doing annual servicing on my petrol so I'm trying to see if I can avoid servicing with an ev

Cars still need to be serviced to some degree.

Tesla is probably the least ‘onerous’ of them as they don’t require you to undertake any of the recommended maintenance to maintain the warranty.

They recommend:

Basically, the only thing to change ‘regularly’ is the cabin air filter but you’d want to do that anyway as they get filled with debris and start smelling after 2-3 years. Other than that, it’s just routine maintenance that would apply to any car regardless of drivetrain. Rotating tyres is option as it always has been.

Most manufacturers require an annual inspection at a garage of some kind to maintain the warranty.
 
CUPRA 2yr service today. Pollen filters and brake fluid I think. 20k miles so needs rear tyres very soon and the rear hubs are clicking so maybe they can fix that but it’s a 4h setting time on the glue they use

Most full electric cars are on two year recommended inspections by manufacturers, but they are really just that - an inspection. No oily bits to replace for maintenance such as oil change, spark pugs, etc of course so it is just the mechanical elements such as suspension. We had to replace our ID3's front drop links at 35000 miles and 3.5 years but nothing else. Brakes are also far less of an issue as the majority of braking is through regen.
 
I'm coming up to a year of owning my ID4 Pro+ 77kwh.
Pros
Like driving a golf buggy, very easy to drive as it's auto it helps my dodgy knees when in heavy traffic.
Decent(ish) economy. I have averaged 3.4kwh/m over 13k. Most of this motorway driving between Derby and Slough, sometimes M1/M25 or M1/A43/M40 at national speed limits.
Lots of space in the back, family never complain.
It's comfortable enough, real test will be in October when I drive to Cornwall.
Easy as anything to use the compatible Tesla chargers.
The standard Moonstone grey colour is actually rather nice.
I do like the positioning of the gear lever.

Cons
Infotainment - laggy, slow and prone to crashes. Takes ages to connect to my phone when getting into the vehicle.
Safety measures - the lane control is annoying, you can turn it off but when you get back in the car later it re-enables.
Auto cruise - it's almost got my flashed a few times when it randomly decides to up the speed to 100mph!! I think the recognition must pick up the 100kmh signs on the back of trucks or something. PITA
There are areas on the bodywork that attract dirt and even straight after a wash and a quick drive, the dirt re-appears (lower portion of the rear doors)
Don't like the fact that everything is on the touch screen, cannot initiate a call from the steering wheel controls.
The unlit heating controls, don't really bother me but I can see why people complain.
What muppet thought it would be a good idea to just put the rear window controls on the front drivers side on a button that means you have to switch between the front and the rears.

Am I glad I went for this over some of the other options, yes as at the time the Tesla M3 was £150 a month more expensive. Polestar 2 was another £100 more. It struck the balance between cost and practicality for me.

(does anyone watch full youtube videos - ffwd)
had direct linked the section related to 3rd paty model 3 battery warranty, which were discussed earlier in this thread too, nice to see them(such warranties) being deployed now
- you don't agree ? especially for I-pace, once outside of scope of those mftr warrantied battery module changes.
