Electric cars

Apologies for the pedantry, a tricky question for normal households, but I suspect a relatively easy one for EV households.

Possibly, but you haven't mentioned standing charges. ;-)

I'm such a low user than it's (still, just) worth my while paying an extortionate unit rate for gas and electric and having a zero standing charge. PV, an immersion and a woodburner do the main work.

If I were to get (more likely when, based on SH prices ) an EV all bets would be off, and the same if I could persuade my GF to move in as usage patterns would tip the balance.

Getting PV changed my behaviour and I'm sure getting an EV would likewise, but it's very much the case that we have to work out our own situations. Anybody any good at Excel functions? :-)

Hi. Actually I didn't mention them as they were the same within the BG tariffs I quoted*, and I stressed the need to search tariffs for the individual.

*TBH the E7 tariff SC was higher at 21.97p/day v's 21.9p/day, but I concluded that I might have written the normal one down wrong, but either way couldn't be bothered to check as the annual difference would only be 26p pa.

As a low user, it's reasonably safe to assume that the EV consumption would be a proportionately large increase, so E7 is most likely a safe bet, but obviously research would be needed. I'm in a similar boat with very low import (thanks to PV), so an EV would most likely more than double my import.

As a lot of my import will already be nighttime (again due to PV), and we'd make an effort to shift some winter consumption (DW, WM etc) onto E7, it would be a very safe bet for us.

Edit - sorry for waffle, but thought I'd expand on that just as a mental exercise. So we import about 1,500kWh pa. I know that summer demand dropped from 7.5kWh to 2.5kWh per day after PV, so I'm going to assume (guess) that half that 1,500 is nightime (though not all E7), so let's say 500kWh, then shift some more demand over to E7, so 750kWh, then add on 2,000kWh's* for an EV (we do about 8k miles pa), that gives us:
2,750kWh E7 and 750kWh daytime. Gotta be E7, the impact of an EV on a low import household is actually magnified.

*I'd like to think some charging from PV, especially in the summer months when 3kW+ export for 4hrs+ straight can be safely assumed on an average or better day, but I don't know how simple this is to manage. Anyone?

Article on the 'production ready' Sion, and a photo of the sockets (not plugs ) for powering household leccy items, or even households.

Sono Motors Reveals Solar-Powered Production Vehicle

Note - I'm a huge fan of solar/PV, but the title is a bit naughty as the car is leccy powered, not solar powered, it's just that the leccy can come from solar, which is of course great news. Pedantry over

Bidirectional Charging (biSono)

Under the charge door (positioned in the middle of the front nose of the car, like a Nissan LEAF), the Sion has two extra ports other than the CCS plug. One is a standard European 220V household outlet to run nearly any appliance from the vehicle’s battery. This could be useful for camping, emergencies, or, as was done in one demonstration video, making coffee at an event.

Next to that, it has another 11 kW type 2 output plug. This can be used to charge other electric vehicles, or potentially for powering one’s home with an adaptor. This way, the vehicle could be use to “rescue” stranded EVs, provide backup power during outages, or do anything else you want to do with the power.

Will they be releasing other photos later, when they've removed the prototype's camouflage disguise/cladding?


Covering the thing so broadly in solar cells - even down the sides - is certainly bold. I wonder what that'll do to collision repair costs?


€16k + battery (estimated €9.5k or lease). Seems ambitious - they must have some heavy financial backing that's prepared to do some serious early-stage loss-absorption.

The "single product" strategy means we can forget RHD, too, of course.

RHD TM3 spotted in UK ............ like weather conditions.

Couple of fun items folk may enjoy on this video.

Just before the 40min point is a cool image transposing the Model Y over a Model 3 or perhaps it's the other way round, a TMY that's eaten a TM3, so you can see how almost identical the nose and wheelbase are, just with a higher arching roof. Certainly not an obvious looking SUV, but then it's not got an obvious SUV Cd either.

And straight afterwards, so just after the 40 min mark is a DIY'er who plays with EV RAV4's, but has built a range extender trailer (basically a trailer with a battery on it), and is currently building a small caravan(y) thing atop another battery/trailer, so a range extending mini camper.

Great ideas, and fun for the whole family too as they'll probably keep 'you-know-who' busy for ages trying to come up with negatives and criticisms. :rotfl:

It's a good work-around for that tricky balancing act between excess weight and restricted range.

Not exactly startlingly original, though. Trailers generating coal gas and wood gas as vehicle fuel were fairly commonplace in the war years.


...and every now and then, some nutter keeps resurrecting it as an eco option.

As always, you seem a bit confused, the article (had you watched it) has nothing to do with coal/wood gas, and neither does this thread. Weird!

<sigh> I'm sorry if it wasn't quite unsubtle enough for you.

Extra fuelling provision in a trailer, because space constraints inside the car make it impossible to provide adequate internally.

There, clear enough?

Sorry Ade, but as always, your posts make no sense. You said the idea of an EV range extender battery trailer wasn't new, and posted info and images of coal/wood gas trailers.

That has nothing to do with what I posted for the enjoyment of those that might actually be interested in EV's.

Oh, and I should add, I'm once again sorry for the confusion you are experiencing, but can only repeat what I've said many times before, and that's that you should really watch or read the links I attach, rather than just post errors.

<Sigh> already looking back fondly on the few weeks of peace we had on here.
