National Grid to drain electric car batteries at times of peak demand

WWW.TELEGRAPH.CO.UK

---

Trial will see cars plugged into grid to ease burden on Britain's creaking energy...

EVs may help keep the lights on 😂

About time

 

It's been proposed for a long time the EVs could be used for helping the grid out at peak times.

So what happens when you need to use the car that you have paid to own for the convenience of being able to go out in at any point you decide to, only to find the battery is flat because someone else fancied a cuppa?

smart meters and surge charging, where is it going next?

Not read the article but the idea that I heard floated was you will agree to have X amount of power used. Say you have Renault Zoe with a 52 kWh battery which would give in excess of 200 miles range but you know tomorrow you are only going to be a 20 miles round trip to work. To play it safe you might agree to have the grid use 30 kWh of power in your battery still leaving you with 80 miles range. You wont be doing this for nothing and will undoubtedly be paid above normal rates for the power you return to the grid. Then you will recharge another time when there is less demand and at a lower rate than you get paid. You make a few quid on the side and grid can have spikes in demand smoothed without the need to have excess power station operable.

A bit like why I got my home battery except aprt from Octopus no one seems to be offering a decent offpeak rate unless you own an EV car charger at the moment otherwise I could top up ,y battery after midnght and never need to draw at the peak rate.

Imagine it being ok to steal the petrol out of the machines not in use in the workshop!

 

Maybe drain the diesel out of your storage tank to boot. Madness.

I understand self-sufficiency and been looking into batteries and they viability for domestic power either off-grid or FiT.

Batteries have a finite lifespan and their management software determine how many recharge cycles they can usefully do over say a 5-10 year period. A bank of Li-Po leisure batteries doesn't seem to be the answer yet. @Dean Lofthouse says he's on lead acid. What have you got?

 

I trust your technical grasp on investing in such a thing so I'm most likely missing something from my youtube researching. :)

Lithium phosphate, warranted for 7 years so may still be working after that.

 

My main problem is I use too much electricity for cooking otherwise I would be self sufficient most days at this time of year.

 

Economics don't look too good in the absence of very cheap offpeak power, at the time I ordered my battery I could have a 5p off peak tariff and a 16:00 to 20:00 high tariff of 30p but this is not offered now.

 

At current rates my total solar PV and battery installation is available for £8k and generates  3MW/annum. IF I utilise all that at current rates  of 28p/kWh that saves £840 but the investment is a wasting asset and only time will tell if it would  be worthwhile doing now.

I was talking to a friend (who is often in the know) today about the energy ratings on houses and how poorly insulated most of the housing stock is here in the uk. He thinks that the government aren't going to regulate the house builders and landlords, but they are looking at telling mortgage lenders that their portfolios must have an average c rating across all properties. Its and interesting thought thats for sure.
