Indeed nothing stopping it running both systems.
If you swap out the word only for mostly then I think that is the general consensus of most at the moment. Home (or workplace if available) charging needs to cover the majority of your charging needs for the financials to stack up.I really only see EVs working if you charge at home, otherwise you may as well have an ICE car.
Had my first experience of electric car ownership as I travelling to and rom Heathrow with my colleague who has an i4.
Firstly, my god they are quick! (In a straight line). But they have no ‘soul’ or personality. It is just a quick washing machine.
This also affirmed why I wont be diving into the EV market anytime soon (partly because I am not convinced EVs are the future).
I charge to 100% if doing a long trip and want to minimise public charging, so maybe 10-15 times a year.. this used to be more but the `model Y LR can easily do London and back on 80% for me, so don’t bother now unless doing more than 150 miles each wayAnother question!
How often do you guys fully charge to 100% as apposed to 80%?
Whenever I need it. 3 times in the last week but that’s unusual, once or twice a month is more typical.Another question!

The equivalent 4 series (non-m) is also a soulless vacuum cleaner..Had my first experience of electric car ownership as I travelling to and rom Heathrow with my colleague who has an i4.

First charge stop on the way down…….his BMW pay card thing (which was supposed to work on the charger) didnt work. So had to resort to getting another app, and paying via that. Took several minutes to sort out, before we even started charging.
On the way back, we had a much more successful stop. Payment accepted first time, and charged at about 130kw or so. But at 80p or so per kw (or whatever the unit is), it wasn’t cheap! I really only see EVs working if you charge at home, otherwise you may as well have an ICE car.
Also, at about 10% left (before we stopped at the aforementioned charge stop), we really were at the mercy of what charge points were on the way back, and were available. Luckily, the BMW charge map did seem up to date, as we tried a stop near a BMW dealership that said 2 of its 2 spots were taken. Alas they were.
That’s completely wrong. Heat pump in MEB heat’s cabin much much faster than any heating element can do. Getting rid of foggy windshield takes about 30s as opposed to minutes. With a heated wind screen those icey wind shield is no issue. You can’t achieve the same results with just heating elements.Just energy efficiency, if anything it will heat slower from cold compared to a resistive heater which can ramp up to full power almost instantly.

The only reference I made to a MEB car was the price.That’s completely wrong. Heat pump in MEB heat’s cabin much much faster than any heating element can do.

Heat pumps can chuck out great deal more heat than heating elements given the same electrical energy input use much less energy to produce the same amount of heat output.
In my Enyaq the heat pump generally use about 800-1000w of energy which probably does a job of a 2kw heater.

Heat pump CoP is 200-300%. Some large scale commercial units can go up to 400%. That means they generate 2-3x more heat out than the energy put in. Where a heater at the most can only do 100%.Ie turns 100% of electrical energy input into heat output.The only reference I made to a MEB car was the price.
They simply can’t have the same output if that is the case. If a resistive heater has the same output as a heat pump, it will heat what ever it’s heating at the same rate plus it’s start up time. A heat pump doesn’t defy the laws of physics.
Touch a nerve? I’m well aware on how heat pumps work.Heat pump CoP is 200-300%. Some large scale commercial units can go up to 400%.

If you don’t believe me - go back to your GCSE physics or just google heat pump CoP.
This is not magic or supernatural - just simple exploitation of phase change of a fluid.
Similar exploitation of small energy input resulting larger outputs are everywhere such as combustion, chemical reaction, nuclear reaction etc etc.
We have an MG4 as a pool car at work and I've got to admit it is really nice to drive. the indicator clicking sounds a bit cheap and it's cloth seats but the actual driving is nice and smooth and really rapid!Me and the wife have had cars since 1975 and we both agree the MG4 is the best car we have ever drove so it's horses for courses.
I do compare it to a fast bumper car though

Rather than me revisiting my GCSE physics, I’d suggest you revisit what the post said rather than responding to something you thought it said.
I specifically said the same output, you have referred to inputs. A 4kw resistive heater and a 4kw heat pump have the exact same heat output. To reiterate, for a heat pump to heat something quicker than than a resistive heater, it must have a larger output.
The benefit to a heat pump as you say is the heat pump needs less energy input to achieve the same output.
As I said originally, the selling point of a heat pump is energy efficiency.
Indeed.Classic case of people on the internet talking at cross purposes
