Site electricity usage - recharging electric cars???

[AndyPK]

We have an electric car and have seen a steady increase in what we pay, you pay per kWH and the price varies massively, with some charging £0.70 per kWH. As people are effectively forced into electric vehicles this is only going to get worse. Paying for what you use is the only ‘fair’ way, but I can see that for a site to retrospectively fit the equipment is not practical or cost effective. If we are using our Motorhome I can’t see us either towing or driving our electric car around with us so we can charge it up on EHU

The only way to ‘tow’ an EV would be on a trailer, wouldn’t it…….?

If EV charging points charge different amounts for units of electricity how is this legal? I appreciate that different companies might get better deals but if the charges are significantly different I am still uncertain how this fits with not making a profit from reselling electricity. Happy to be enlightened.

Back to people charging EV vehicles on site...... If this becomes more prevalent with caravaners and "toads", I believe sites will be forces to make one of 2 choices, ban recharging (difficult unless policed) or put up costs to everyone using EHU. ( My prefered choice would be metered supply but I accept this may be impracticable/very expensive for site owners) Additionally, some will always use more electricity than others but so long as has a relatively small impact I guess most will not care to much. However, if costs have to go up significantly I will certainly feel aggrieved at subsidising EV owners. (Please do not come back with I dont have to used sites if I dont like this situation, I know we all have choices and mine is to use sites but not to subsidise others!) Finally, when I use EHU, I use it on the site, EV owners take the electricity with them! (Yes I know the hab battery may be fully charged and electric bikes may take some but this is relatively minute amounts compared to EVs - site I was on last week the EV owners went off site seeing most days and then recharged over night so he not only got a free charge for his ongoing journey but for all his holiday trips!)

I wasn’t aware of the not selling electricity for profit, I guess Car recharging is different, you are paying for the extra speed the higher charges are for ‘Ultra’ fast chargers, fast chargers 50kWH are typically £0.50 per kWH, still more than any electricity company standard tariff, at least for the time being.
My understanding is you need to trailer electric cars having the driven wheels on the road when being towed could seriously damage the car.
I prefer to charge at home where a full charge will only cost £3.00 (max 200 miles)

I know is going off thread but just to mention, some ev’s can be charged by towing them. The 4x4 type vehicles used in the last Ewan McGregor/Charlie Birman Long Way series even got a passing lorry to tow one of them for 30 minutes so they could continue. Was either a tow or big generator wagon where they couldn’t get proper charge. Lots of different technologies being used in different makes at present

Its not the norm, but twing Teslas puts plenty regen in. Surprisingly up to 50-70kwh.
Id imagine same on all others with regen

No idea exactly how theirs worked just saw them doing it. The vehicles used were fast track prototypes made for the show similar to the EV Harleys the main two rode. Cutting edge stuff really as where they were going had no infrastructure except what the show sponsors fitted in. Couldn’t remember who the company was so looked up and posted here:

It is possible to have the car powered up and in Neutral, if you towed it then you aren’t going to get any Re-gen to charge the battery, if you engage drive it would be like driving with the brakes on, not a particularly brilliant idea, neither is running a Dirty Diesel engine to charge up a green BEV. And what happens when you battery is full?
I have been interested in what Rivian has been advertising for the last 3 years, they need to pull there finger out. As Elon Musk found out moving to mass production of vehicles is the most difficult challenge he has faced.
Back to charging on site @ 10A or 2.5kW a really efficient BEV is going to recharge at 10 miles per hour, so anyone hoping to charge their car is going to need to be very patient.

Its probably one of the freest, most independent markets there is, when you take CL’s into the equation

Who in ‘your view‘ do you think ‘regulates” the market?

CLs by their very existence are highly regulated, limit in size to a maximum of 5 units. The two main exempting organisations limits the market further by restricting it to members only. The CCC also restricts THSs to members only. The much smaller MCC doesn't make such restrictions but they are insignificant in the market.
A goodly part of this thread is devoted to the regulation of the electric supply market. Before I had my large capacity lithium batteries and an effective B2B charger I was regularly discharging my leisure batteries to dangerous levels. In Germany I could find places where for 2 euros in the slot I could get 1 unit of electric. Since I could use it over 24 hours I could recharge my batteries.
2 euros a unit is expensive electric but 2 euros for 2 fully charged batteries was a brilliant deal for me, I bought it several times. Regulation of the UK market prevents anyone offering such a useful service.

No one regulates the UK market

, you pay per kWH and the price varies massively, with some charging £0.70 per kWH.

& how does that work with " you cannot charge more per unit than it costs?"

s but if the charges are significantly different I am still uncertain how this fits with not making a profit from reselling electricity.

Yes, as above

, I guess Car recharging is different,

No it isn't .There is no differentiation.A unit of elctricity is a unit.

you are paying for the extra speed the higher charges are for ‘Ultra’ fast chargers,

As above .

£3.00 is about 7.5kWh - is this enough for 200 miles? A diesel would only go about 7 miles on that much energy!

 

[Nedge68]

You are not paying for regular mains at fast chargers they are DC. When fast charging, the AC to DC conversion built into the car is bypassed. I have no idea how much these chargers cost, but no one is going to invest literally thousands of pounds for a fast charger then only charge you the cost of the unit price of electricity.
I only use fast chargers on a long journey. We drive a Tesla Model 3, the Tesla Superchargers are simply put, brilliant, and are way ahead of any other charger network.

 

[Nedge68]

£3.00 is about 7.5kWh - is this enough for 200 miles? A diesel would only go about 7 miles on that much energy!

depends how much you are paying per unit, I pay 5p per kWH between 0:30 and 4:30 my battery is 55kWH, £3 pays for 60kWH even allowing for charging losses only 1.5p per mile, pay fast charging rates £0.70 and that becomes 21p per mile
A Tesla M3 will travel 4 miles on 1 kWh so using your figures 30 miles on 7.5kWh, electric motors are the most efficient way of transferring stored energy to motion.

 

[dunnah01]

I pay 5p per kWH between 0:30 and 4:30

Wow - that is a great deal!

and try 3-4 miles ph for the larger ones

I wouldn’t charge up on a site EHU, because I wouldn’t have anywhere to plug in my inflatable Spa!

 

[EzeeRider]

On the early morning news today was an item about solar panel charging of electric cars. A firm has developed a system to charge 12 cars at a time which can be erected in 9 hours and is planning to role out dozens of these in the next year. It was stated it will take about 3 hours even in the winter months to fully charge an EV. Cost to charge was not mentioned.

And ‘probably’ defies the laws of physics too…..!!!

it did say that the solar works in conjunction with mains electricity and not solely relying on solar.

They already have one sytem in and working. A bank of solar panels formed a roof under which cars parked and pluged in. It had in built battery storage and presumably an inverter unless it was DC charging? No different to a house roof installation and that works.

I missed that.

[Jamesh]

Sounds like a large extension lead!!

 

[chrisgreen]

Wow - that is a great deal!

I pay 4.5p a unit between 8.30 pm -1.30 am that's 5 hours a day and 13.8p a unit for the remaining19 hours

 

[Gromett]

Why cloud cuckoo land and why defying the laws of physics? If the solar panel array is big enough where is physics being defied?

Come on Gromett , 3 hours to ’fully-charge’ an EV, even in winter…..!?!
Maybe if the EV battery is only a little depleted - if not, how large would the solar array need to be, bearing in mind it is proposed to charge ‘up to 12 EVs’ at a time………?

 

[nabsim]

The systems they already have in place for charging ev’s is in need of a lot of work in many cases. Problems have been identified for lone women and disabled to mention two groups. While you get maids/apps telling you where a charge station is the report I watched said they did not have real time info on if they were actually working.
We have a long way to go yet methinks

Yer right enough solar can be installed in 9 hours to fully charge an EV in 3 hours in winter, pull the other leg.

Let's take this in it's component parts.
Why is it hard to understand that'
a) An EV can be charged to full in 3 hours.
b) That it is possible to build a large enough solar array to support 12 EV's at a time?

Which bit is fantastical to you?

How about ‘can be erected in 9 hours’ for starters…….?!
