The EV fact thread

[Bellow]

No need for dynos....as discussed elsewhere on the forum. EGR is basically for taking care of the emissions at the idle

Really, it isn't.

( though it helps at other engine speeds also). so if its working at idle I think they can safely assume it working under load to

How can they check it is working?

....not that they do much then as they are usually fully closed under load or you would loose all your boost through them!!

Exhaust backpressure exceeds inlet pressure.

True....but largely self inflicted....anyone with EGR, DPF AdBlue deletion knows full well that its illegal, voids insurance, lumbers you with a potential £1000 fine etc....so they made that choice. Cant do the time etc......

True, but when it costs £2k to put right, I have some sympathy.

If it takes more illegal, polluting dervs off the road I'm all for it.....and I have two fully legal dervs on the drive!!

Unless and until it happens the whole 'clean air' argument is a sham.

How many people bought EV's in 2011 ?

Your article says that in 2020, the subsidy was reduced from £3,500 to £3,000. (It was set at £3,500 in 2018)

Which part of

''The plug-in car grant scheme was introduced in 2011 to support the uptake of ultra-low emission vehicles (ULEVs). It was originally set at £5,000 for all eligible ultra-low emission cars but has been slowly reduced over the years.''

don't you understand?

So many facts, so little time

But the punter has paid MORE VAT to the Government by buying an EV for typically a third more than its petrol equivalent.

I can offer you a £3,500 discount in 2018 if you buy a new Mercedes EV. You might "think" you're saving money,

but from my point of view, I'm getting a sale which I wouldn't have made,

and I'm getting more money from you than if you had bought an ICE

You can pay a small monthly subscription to pay the same rates as Teslas, a fair compromise to access (some UK sites) of the best charging network.

Yup. The original question was just whether any chargers were capable of charging different p/kWh rates to different customers, which Superchargers can.

The £10.99 monthly subscription to pay the lower 'Tesla' rate is fair enough, but there are only about 40 sites open to non-Tesla cars across the whole of the UK (11 of which are around London). So IMO it would only make sense if you're going to be near one of these fairly often.

 

[markjay]

One can clearly see petrol/diesel prices and can choose a different outlet accordingly but the (perhaps home) EV charge point is less obvious?

My various EV apps all display the price per kWh for each charger showing on the map. It's actually much easier to plan cheap charging using EV apps, than to compare between different petrol station prices.

 

[markjay]

Doesn't that apply to all Tesla chargers that are open to other makes of car?

No. You may pay different rates depending on the type of account you have, but not the type of car (not yet, anyway). Tesla do not have different prices based on the model of the car being charged.

Even Tesla drivers have different accounts and different rates - a colleague at work for example had a deal with his new Tesla that included free electricity for life. So someone with an identical car to his would pay while he didn't - at the same charger.

Same with Ionity and BP Spark etc - the price depends on the type of subscription you have (the most expensive being buying with bank card at the charger and no subscription) - but, again, this is done by recognising the user account, not by recognising the specific model of the car.

So, yes, you could in future tax some individuals more than others - but not by car type/model (again, not at current, and I am not aware that this is planned).

That was then and the wisdom of offering any subsidy to early adopters who would have bought anyway is moot. The debate however was about whether subsidies should be made available currently.

 

[BPD07]

Outrageous, innit ?

It's like Ford, Vauxhall, Renault or FIAT type depreciation / residuals.

OK, the MG would have been cheaper in the first place, but still

Somewhere in my brain, there’s a voice saying but this is normal, 50% depreciation over three years is more or less correct. As it is, we bought used, and for our local (well 50 miles radius) needs it’s the right vehicle. The instant torque is a hoot at the traffic light derby as well.

And surely you’ve halved your fuel cost,

and reduced your Road fund licence

And got an interesting new tech car

and had bragging rights from being “the first in the street / in the pub / in the office to …”

You think perceived “discounts” don’t work?

Anyway, got to rush. It’s £2 a pint off Youngs Special in the Dog and Fox tonight.

I was going to have a quiet night in but

hey, I can save £8 !!

New eqs refresh announced...

I'm not sure it works for me ... arguably I find the original front end better.

But how does that work if as a single user you have two Teslas ... one with free charging, and the other not? And perhaps a 3rd EV that's not a Tesla. Charging must surely work at individual car level, rather than account holder.

How can they check it is working?

Well I can check mine is physically working just with my obd2 dongle and my phone... so I'm sure they could with a slightly more advanced bit of kit. That combined with a NoX gas tester should be all they need.

I'm really not buying NOx being testable at idle. NOx production is dependent on a pressure and temperature history and there's sod all pressure (boost) or temp at idle. NOx is problematic under load when in-cylinder pressure and temps are high and that requires a dyno or a vigorous road test and there will be resistance to both. At least if it were police doing spot checks not all cars would be subjected to this annually and, as the police would be testing under the auspices of suspecting a crime - much harder to object to.

 

[markjay]

Is this really going to happen? It will require MOT testing stations to install dynos.

Isn't it how they currently test brakes?

Why test it at idle? Diesel emissions aren't being tested at idle either.

 

[ALFAitalia]

Google it...... most of the time the EGR is functional is at idle... which is its main job.

This is from Delphi...a major maker of EGR valves.

The EGR valve has two primary settings: open and closed, although the position can vary anywhere in between. The EGR valve is closed when the engine is starting up. During idle and at low speeds, only a small amount of power is required, and therefore only a small amount of oxygen, so the valve gradually opens – it can be up to 90% open at idle. However as more torque and power is required, for example during full acceleration, the EGR valve closes to ensure as much oxygen enters the cylinder.

The basics of EGRs - what they do, how they work, how to troubleshoot

Integral to the vehicle’s engine management system, the aptly named exhaust gas recirculation valve, or EGR valve for short, recirculates finely metered quantities of exhaust gas to the engine...

Powered rollers are used to test brakes.... not a dyno though.
