Dumb tariff

Yes, it's all about balancing the loads. Not just on the wider grid, but within a household. I could see a situation where an ASHP or tumble dryer kicks in, and the car charger makes a decision to temporarily reduce the power available to it.

I'm still waiting to hear about how I'm going to get paid for not-using my tumble dryer during periods of high demand.

This is already happening. Most EV chargers have a CT clamp to monitor house demand.

I don't see why, You may still get a guaranteed charging period but possible not enough to fully charge a completely empty battery every night but isn't the well rehearsed argument against the anti EV brigade that in the UK the average commute or usage only requires a small top up each day.

Are you possibly erroneously assuming that cheap off peak electricity is going to continue in the near future? To met targets and a threat of banning certain products from sale means what used to be surplus capacity during the night is becoming a new demand.

Perhaps there will be no cheap EV charging periods for many months during the year when more people buy EVs and when 70% of household are gradually weaned off of natural gas central for heating

As for cheap EV tariffs, the cheaper ones a likely to be those when the customer is more flexible about when the EV is charged. It doesn't stop others from charging at other times with higher price electricity.

As with most polices Left and/or Green the consequences of policy success have been ignored: Namely that nothing in the policy will compensate the government for the massive loss in road fuel tax income engendered by large take-ups of EV ownership Nor that widespread overnight charging will absorb so much electricity that it will no longer be cheap .

Nor yet the problems loss of electricity made far more likely by widespread adoption of 'renewables' will engender to houses and their occupants with no other form of heating,

Policies driven by ideology rather than careful cost-benefit analysis are doomed to failure.

There wont be any cheap tariffs at all. And there will be massive taxation on electric cars. And almost certainly an abandonment of Milibands 'Net Zero Nonsense'

certainly, when I used to commute by car it amounted to 50 miles per day.

that's what my home installation has - but I've only got a 60A incoming fuse.

Yes, although E7 doesn't require a Smart Meter, and pre-dates by decades smart meters. The dumb meter version just recorded the rates, using the timeswitch/RTS receiver to switch between peak and cheap rates as required, and recorded two sets of readings.

The modern implementation of E7 uses a Smart Meter solution (in a dumb fashion). The only 'smart' bit is remotely sending those readings to the energy company.

As Theo says Smart EV tariffs provide cheap rate electricity at any time of the day or night (based upon network demand and pricing) but you are additionally guaranteed a core 5 or 6 hour period overnight, when the electricity is at cheap rate.

The quid-pro-qua on those tariffs is your EV might not be charged overnight, and instead in the evening (before 11pm) and/or in the morning after 6am. You have to specify a 'Ready By' time, which (in the case of Octopus) cannot be before 4am or after 11am

Indeed, I've had sessions where there has been no overnight charging, and everything has been concentrated into the peak hours (but still charged at cheap rates)

That last phrase sums up the way things are going; it's designed to confuse. It's all too similar to car insurance where it's almost impossible to work out the best offer on a comparison site. Unlike car insurance, however, as yet you can't try an offer with your current utility company to see if you can get a better deal!

Depends on your commute, and what leisure trips you may have done on Sunday, or propose to do from 5pm Friday.

And I'm told one of the more common service calls to the charger company is when a smart meter is installed at the house and the clamp is discarded by *that* fitter.

Unless you have a 100 Amp incomer fuse, the CT clamp is a requirement ?

Maybe you *should* but in practice *can* you. And without spending a quarter of an hour poking an app with the world's worst user interface.

EV's do "work", fsvo, but they impose a significant externalisation of costs, and effort, compared to internal combustion cars.

And avoidance of a significant amount of Fuel duty, plus 20% vat on top of that fuel duty. At some point government of any colour will have to make some unsubtle taxation changes to compensate for the loss of that nice guaranteed stream of government revenue.

Centrica Boss thinks electricity prices will be higher by 2030 than they were during the immediate fallout from putins invasion of Ukraine.

That's commencing in April 2028 isn't it? 3p/mile for BEVs and

A pretty incisive statement there Roland.

nearly all my transport needs could be undertaken by an EV... But its when an emergency call to be 300 miles away comes in at 2 a.m. that I wouldn't be able to cope..

Exactly,. If everyone adopts EVs they cant be allowed to be cheap...

They will if mad Red Ed Milibrain has his way.
