Honestly don’t know how people tolerate 3 pin charging and also the lower charging efficiency it brings.

Yeah 3-pin is great for a backup and for unexpected charging requirements, e.g. relatives and friends who may live far away, or if you get stuck somewhere with no other option.
People need to consider it an just like a washing machine or similar home utility, there is a cost but it also has a big benefit.
My work commute is 3 miles each way. A full charge will prob last me a month. Doing a 24 hour charge once a month will be fine
And I will prob charge it most of the time st work for free. The plug will be a back up most likely
I know from dropping my son at school (4.4 miles there and back) that short runs kill range, especially when it’s cold and wet.
Today I used 10% of a 75kWh battery doing that trip twice - 8.8 miles.
So that works out to just 88 miles of range, on a full battery doing those trips.
However, I can achieve about 220 miles when driving on a single trip of that distance.
Means you might be charging more than you think.

It's fine until you want to drive a few hundred miles over the weekend or something, while that is not every weekend or perhaps even every month, when it happens it becomes a right pain in the proverbial.
I don't use my car for commuting and I wouldn't consider living off a 3 pin long term. It was 'okay' for the 2 weeks I didn't have a charge point but it wouldn't cut it long term as you really don't need to drive very far for it to become a problem. I want to be able to get home empty and the next day it be back up to 100% again and not have to worry about it.
Yeah some cars really suffer from with short trips, not sure how bad the PSA cars are like the e208 in question are. Did 9.5 miles today (2x 4.75) and used 7% of a 38.3kWh battery, very hilly drive, and very wet today, that is about as low as it goes for me.
I wonder if the engine oil pre-heated, such that if you do solicit the engine it's not like a cold start at 40mph, say ?
albeit, in an ICE on a frosty morning start, I always aim to pull off as quick as possible without idling, to get some heat into the block, under load, reducing wear.

short ev trips - doesn't the car now give a break-out of the additional energy used for heating the battery, the occupants etc.so at least you know where the energy went ?
I know tesla didn't used to do that and there is an earlier thread where someone deduced the cabin heating / heated seats etc consumption

No engine oil is not preheated on a PHEV, would be pretty crap for trips when the engine didn’t start…
Why would anyone really care about that sort of detail of energy breakdown aswell.

That’s the battery trying to heat itself up. Can’t you precondition?
I've been granny charging my 60ah i3 at my flat for the last 30 months. It'll do almost a full charge on the "Maximum" speed during my off-peak hours of 22:00-06:00 so it's perfect.
Thankfully, it's not my only car so I have another if it's out of juice or I need to go more than 60 miles.
Granted, I wouldn't be able to do that on a 120 i3 or comparable vehicle. It's a problem now because we have a plug-in hybrid with a 17kw battery too. Am moving to a house over the summer so will get a 7kw charger installed ASAP.
Wait what?
You used 7.5Kwh to do 8.8 Miles?!
That's 0.85kWh per Mile!
Post April unit price that's 23p per mile... o.O @ the CHEAPEST domestic unit price... the fast chargers are upwards of 2* the domestic rate.
30MPG car doing the same trip is 25p per mile at £1.70 per L of fuel.
What is the actual point of the Electric car...

EVs also suffer from “cold starts” but that does seem incredible. Guess the new dangled android infotainment doesn’t do trip averages in car and phone app like my crappy car?!
Local air quality & less oil imported are two reasons…
oh he’s got 400bhp too.

that’s just luck of the draw for dealer stock… no one has stock.

Yes yes, green energy blah blah. Problem is, 90% of consumers want cheap.
Having to buy an EV to then basically pay the same cost to fuel it.. doesn't shout cheap.
Plus that battery will degrade by 15 years... normal ICE may still be absolutely fine and dandy.
EVs, are no where near being a suitable long term replacement. Especially with the cost to power them shooting up.
When I pre-heat my M3 it pulls 8kw from the mains then slowly drops as it heats. Not exactly sure how it much pulls when unplugged but I have seen 2kw in the past just sat on a very cold day maintaining the cabin temp (Scan My Tesla). There is now some extra battery pre-heating done now too if I start that early enough. Add in high resistance from a cold battery and maybe the HVAC being cranked up too then yeah I can see a few short journeys having a noticeable impact on range.
I think I was at 55% charge yesterday and 44% charge today when I checked. I only did a short journey across town to shop and then the car has sat so between the that time it's basically lost 10% from a 50kw battery. Some of that loss this morning would be reduced capacity from cold so may recover a percent or so as it warms.

Pre-condition for a 4 mile trip - not sure if serious !

Yeah, my previous diesel car didn’t do so well on MPG for these short trips either !
Also, my charging rate is 7.5p
So in this short trip scenario it costs me 6.4p per mile, rather than about 2p per mile on a longer journey. That’s the point !

I doubt any ICE car after 15 years (~150k miles) will be using all original parts.
As for charging costs - home charging is still very cheap through some suppliers.
