Getting confused about night rate electricity

Reed_Richards

I have an EV.  I don't think that I use it significantly more in summer than in winter but the miles per kWh drops off in winter (because the battery also needs to provide heat) so it needs more charge to do the same mileage.  My EV tariff, Eon NextDrive, gives cheap electricity between midnight and 7 AM.  That's a full 7 hours so just the same as Economy 7.  But you have to have an EV to qualify for the tariff.

The EV tariffs I have looked at just specify an EV, so I guess this would count?

An EV has a specific charging characteristic (a constant 7 kW or a constant 2.4 kW are probably the most likely).  So if anyone from the supplier bothered to look, they could probably tell if an EV really was ever being charged or not.

I meant compared to e7 use for heating home which is far more seasonal - 0 to 75% plus of many bills.

My winter energy kWh use can be 4x summer in winter and I think I am  a relatively low heater,  your ev likely keeps your summer nightime use relatively that bit higher than mine.

Which estimates average EV user would need just over 45kWh charge per week for a small to medium sized EVs milespkWh.  Thatvwould more than double my summer bills. 

Good that it's a full 7 hours.

Did they mess with any meter timings for alcs load switching if you had that reliance on meter for offpeak heating before ?

I'm afraid I don't really understand the question.  I was on a single rate tariff before I got the EV.  As far as I can tell, billing is done by a retrospective calculation based on the half hourly data.

I guess we can take it you are joking... 🤷‍♀️

Suffice to say, no it will not count.

Thanks.

Some E7 meters do the 7 hours only restricted power circuit control - for load switching on older storage heaters - that have no self timers - and hot water immersion tanks heaters - so they only operate at off peak.  Thats often referred to by the abbreviation ALCS (auxiliary load control switch).

If you were on single rate before - you wouldn't have that feature.

 

Always worried might lose the mode if a supplier re configures the parameter arrays (for tariff rates, tariff off peak timings and ALCS load switching).

And if not on current meters - worried what would happen if meter then changed in future - when supplier might look and see its just an EV tariff - or single rate metering based on 1/2 hourly charging.

I was just commenting that the terms and conditions are very sloppily worded. They really do not define what they mean by an electric vehicle. At least, not the ones I looked at.
