EV general discussion

Not really, they have a plug, thats the whole reason for such a term with the general public.

Regenerative braking people think that has something to do with the actual brakes!

in which case a more honest description of a self charging hybrid is.............. a hybrid that you can only run on petrol. (or diesel... tho not sure if there are any diesel hybrids being made any more)

my tongue in cheek comment about EVs aside, my point is, the term self charging hybrid makes it sound like it is in some way superior to a plug in hybrid......... but it really isnt.

a plug in hybrid is just as self charging as a self charging hybrid, and as much as people here can probably see through the nonsense, i can say with direct experience sadly not everyone can. its dishonest advertising imo and should be stopped.

and............ i genuinely cannot think of anything other than regen braking which is self charging hence me mentioning EVs qualifying.... because charging off fuel is not self charging (imo) its just using petrol as a fuel source rather than electricity

I adore regen on electric. It makes the driving so intuitive and natural

I’ve not got tonnes of experience in electric cars, but I’ve driven my mums Q4 Etron a fair bit and it’s great.

Regen in all situations except dual carriageway and motorway.

It’s not as efficient as coasting and managing speed better, but it’s the most compelling thing about driving an electric car for me.

I think you are missing the point that regen works on either one pedal driving, or with brake pedal regen. So what your are describing is OPD (one pedal driving)

With brake pedal regen the brake pedal does regen instead of friction brakes but it is still 100% regen. It uses regen up to about 3G and your friction brakes only deploy during extreme emergency braking.

It should also be remembered that two pedal driving splits the brakes and throttle giving you more pedal play and a finer control. OPD has brakes and throttle on one pedal obviously, so you get less pedal play for fine control. You can feel this in OPD if you switch modes while maintaining speed and throttle position.

I’m not saying it’s better or worse, just clarifying that regen is still regen if you use your brake pedal.

It’s also important to know that Tesla’s do not do regen on the brakes at all. So only OPD in a Tesla if you want regen.

My mg5 doesn't have opd but slows down to about 6mph, it regenerate when I take my foot off the accelerator though.
Opd is when it stops the car without any input.

True, but regen is either lifting off the throttle, or pressing the brake pedal in most EVs. It’s still regen is my point. Some people assume pressing the brake pedal is not doing any regen and using the friction brakes.

Even your MG5 is still using the electric motors to stop below 6mph (10kph), it does not engage the friction brakes. It’s just a safety decision by the designer to force people to take their foot off the throttle to actually stop. MrRockliffe’s Q4 has the same feature.
 
Just got my Octopus statement for the period 25th August to 24th September and the car took £7.04 of electricity for the month. However, she did get charged on two of the four one hour sessions which I had £3.64 credited back to me so all in the total electricity cost for running the car the past month was only £3.40. Bargain!! I am chuffed to bits with this switch to a EV.

nice one!.

we run 2 evs (ok one is technically a hybrid but we use about 10 litres of petrol a year and most of that is forced running the engine). despite that, our electricity bill is still peanuts thanks partly to intelligent octopus (we also have solar and battery but that is by the by)

before with 2 diesels we were spending probably £150 a month on fuel, and on top of that the cars were far far less interesting to drive... now we pay half that for running 2 cars, and our house energy.

That said............... our cars have depreciated more than i would have liked, but that is not a problem if you buy now.

My polestar only uses the friction brakes below 5mph, in reverse, above a certain level of braking or for the first braking application of the day. The rest is always regen.

You can tell as I’ve used 10% of the brake material after 38,000 miles…

It is dirt cheap indeed, here are my driving and charging stats from the last 30 days.

Get yourself some solar and batteries and your bills with be even less.

My energy bill for August was:
Import 390kwh / £27.50
Standing charge £14.83

But also I generated 1118kwh of electricity and exported 873kwh netting me £130.98 in export payments.

So my net energy bill covering was minus £88.85. That covers the house, car and water/space heating - we are all electric, no gas or oil heating etc.

My bill for the year is looking like it is going to be somewhere between £0 and not a lot - I need to set up a spreadsheet!

And the bill for installing all of that…

Less than you'll pay *insert random utility company here* over the course of the life span of the system by a large multiple.

It's investing in your property vs. giving it to a large utility provider, bit like paying a mortgage vs renting.

This^

But for my setup 8-10 years.

My setup was also quite expensive as it includes whole home backup if the grid drops. My roof is split due east to due west and therefore produces 20-30% less than what it would if it was all pointing south.

You can do it cheaper and therefore pays back quicker, particularly now because prices have dropped since my install was done. Even NNW and NNE panels are viable these days, due north will not be far away either if you are paying for the install.

It’s the fixed install costs that are the cost driver, good quality panels are under £70 a piece.

It’s not just about the payback, you are insulating yourself against price rises and price shocks.

If they decide to decrease the standing charge and put more of those costs on the unit prices, people with solar will be laughing and is part of the justification for not doing that despite that also putting more of the burden on genuine low users.

Haha nah, I just copied the numbers from my post at the end of last month in the solar panel production thread.
 
smart money will invest in the newer ID models with bidirectional charging support - so home batteries&solar less important, faster ROI
(to the degree the car warranty permits its use)
 
Smart money buys second hand.

V2G already exists, just buy yourself an old leaf. I'd be surprised if it ever takes off. It's cheaper and easier to buy a dedicated battery.
