the truth about electric cars
Yes it will, and there by stands a potential fire risk right there in the extension lead. So many of them are only rated at 8 or 10amps because of cable sizes used. Many of the cheaper ones are 1 or 1.5mm cable, and if it was made in China etc, that cable is often steel not copper, which is another problem area.

1.5 or 2.5 mm cable would far better, the losses would greatly less. I take it the 220V is at the consumer unit, or is at the output end of the extension lead?

Defo sounds like losses are being incurred in undersized extension lead. Is it a long one? Is it one of those wind up ones that have the outlets on the side?

@lol-lol With the error that you get from time to time, I'd be inclined to actually get the earthing and all associated bonding on your house and charging point checked professionally. If you do have a dodgy earth connection, one day when you come to disconnect your car, you could receive a nasty shock by becoming the earth bond, which could be fatal. I'm sure that we'd all rather be chatting with you than chatting about you.

Photography Thread
While taking photos of an Omani Air Force Hercules arriving this afternoon at Stansted, a pheasant suddenly emerged from the crops and gave me and my son a checking out for a few minutes, and once it decided we posed no threat, it proceeded to walk towards us and then between and disappeared into the hedgerow.

Are you having issues with your charger showing error codes and your car not being charged? If so then this could be the reason for it.

Modern cars have vents from the cabin into the boot or even directly to the outside of the car via the boot area or quarter panel area. I remember one of the very first cars to do this was the Rover P6, and they advertised this in their brochures of the day, as seen below. I really enjoyed my 2000TC model and also the P5 before that.

There is one there for £999 and delivery tomorrow (prime) but no good for hinged windows either.

@lol-lol was that the one on Amazon by any chance? I have been looking for one as well and there doesn't seem to be any around. Plenty of the sub £100 units on Amazon, but they all rely on either the evaporation process (useless) or blowing air over ice cubes, also useless. Had one of those a few years ago and it did work a bit as long as you had ice cubes. Ice cubes melted long before replacement ones froze, so I returned it as useless. I noticed on some units on Amazon that were quoting deliveries well into 2027.

This is a possible big blow to the continuing rooftop solar installations, particularly on industrial buildings. There has been a massive medical distribution centre destroyed by fire and now a huge frozen food distribution centre is on fire, and in both cases it looks like the solar installations are playing a major part in the fire as well as hampering efforts in fighting the fire.

the truth about electric cars
Well, just because you never had it happen in Scotland does not mean it was not a thing. I have tried to Google it but have not found any real answer to that. But it has been happening to McLaren 765LTs apparently and been the subject of a recall, so it is not an unknown thing, even with today's modern cars. McLaren recalls 765LT because the rear window could fly off | Driving I did find this AI answer, though. AI Overview In the 1970s and 1980s, as automakers transitioned from traditional rubber gaskets to glued-in (bonded) glass, early adhesives frequently failed to hold. When the cabin was sealed and doors were slammed, air pressure and twisting body flex would force rear windows (and windshields) to pop out completely. Some famous vehicles—and specific manufacturing issues—highlight this transition: Rover SD1 (1976): Widely celebrated as one of the first production cars to adopt bonded windscreens in the UK. Early models were plagued by structural flexing, poor-quality early urethane adhesives, and improperly primed bonding surfaces. This combination often resulted in the screens simply popping out under pressure or stress. [1, 2] TVR Tasmin (1980): Known as one of the first production cars in the world to heavily incorporate a bonded glass design (both windshield and rear heating element). The early bonding techniques used on its fiberglass chassis resulted in infamous issues where the glass would lose adhesion. [1] Malaise Era "Pop-Out" Issues (Late 70s/Early 80s): During the era of expanding body panels and experimental urethane formulas, several General Motors and Chrysler coupes with massive, radical wraparound back glass suffered blowout issues if the adhesive hadn't cured properly. [1, 2] The Hatchback/Door Slam Pressure: This phenomenon wasn't always a defect; it was frequently caused by the sudden increase in internal cabin air pressure when doors were slammed or hatchbacks were dropped while the windows were rolled up. Without an adequate escape route for the air, the pressure would push outward directly on the glass. Also, it seems according to the Toyota Owners Club that on some Aygo and Aygo X club models, the rear side windows have been known to blow out; see photo. So it is less BS than you thought, and it is true; this also happened to a bus driver when I was doing my apprenticeship in the late 60s/early 70s, so I actually know this to be a fact. His car was a Vauxhall Victor as shown in photo 2.

Please don't think I was referring to you in that post, I was not. I said younger, much younger. One such person is a family friend, a well known TV football commentator who swears that he is doing the right thing, even though it has been proven.

the truth about electric cars
Well it was a thing. I think it started with Vauxhall Vivas in the early days when started glueing the back window and windscreens on rather than using rubber with wedging bead that been used for years. It happened more on motorways, which of course you probably never had up North at the time this was happening.

Distance from the sea does not equate to higher temperatures; the hottest spot in the UK yesterday was Gosport.

In truth, however, cars are far more efficient with the windows closed and the AC cranked all the way up. Having windows open while driving imposes a far higher amount of drag on the car and hence higher consumption, regardless of what type of powerplant it has. I think that some people just can't believe that, regardless of their age, etc. I know of people far younger than me, with a university education, who have their windows open, rather than use the aircon because they believe the misinformation that it robs engine power so must cost more. I remember back in the 70s and 80s, when many cars would have their back windows forced out with the pressure inside coming from being driven too fast with windows open.

What, 100k deaths in the UK? My, you're a doom-and-gloom merchant 😉. So far we have, I think, 18 dead, but we always get some deaths during the summer months of the elderly who suffer with heat anyway; that's a given, sadly. The 18, as far as I can tell, are not elderly but teenagers who have been swimming in open water and are more likely to have been diving and struck submerged objects. MSM have been issuing warnings not to go swimming in open water anyway. So you're predicting over another 99,982 in the rest of summer; I can't see that personally. The difference with an ICE car in winter is that like the BEVs, there will be drop in range but nowhere near the 30 to 40% drop that BEVs suffer and the waste product of combustion will heat the cabin at no extra cost or loss of range, unlike BEVs who must decide between maximising range or being warm and comfortable. My diesel is actually improving its range as I'm currently using additives to clean the fuel lines and injectors which has added another 30 to 40 miles to each full tank of diesel and more if I do long runs, even with the AC on full.

Yes, sadly though, not everyone fully understands just how these batteries work; they are even more complex than a combustion engine.

I do as well, but before that can happen, they have still to find that mythical magic bullet. While LFP does help, they can and do burn but need a higher temp first. They do however emit more deadly gasses apparently.

Thanks, but I meant, what is the cell model number so that proper calculations can be made? So this is an old e-scooter which you have yourself modified, which, as it happens, also seems to worry the fire and emergency services the most because the scooter was not designed for the batteries that you have fitted and also few people actually have the required skill set to modify things correctly.

the truth about electric cars
Let's be realistic here, shall we? Firstly, those fireman ports are only good if the fireman is actually standing there by the car when the battery enters thermal runaway. It also assumes that he has all the equipment ready, prepared to gain access to that port which is located directly on top of the battery pack, which presumably means it is located beneath the rear seat squab. It also assumes that the hose is already there and the pump is running. Meaning that he has to get into the car first and then remove the seat squab and puncture the sealed port. That is never going to happen anywhere other than in typical demonstrations of what could be done. The following is an extract from a Renault document. The "Fireman Access" port on a Renault Scenic is a specialized safety feature on the electric versions of the car (such as the E-Tech) designed to allow firefighters to flood the battery compartment and stop thermal runaway in minutes. It is typically integrated directly into the top of the high-voltage battery casing. Under normal circumstances, it is completely sealed and hidden. In the event of an emergency, firefighters use the pressure of a high-power water hose to rupture a specialized disc on the casing, which gives them direct access to spray water onto the battery cells. A video made by Renault follows lower down, which shows water and not foam. Water cools down the thermal runaway (assuming the points I raise above; in reality, it is going to take the firefighters, at best, many minutes to arrive at the scene of an EV in thermal runaway, at which point the entire car will be engulfed in flames, so there is no way they are going to be able to do what they show in the video. Fire blankets also do not put out the fire; they help prevent it spreading to surrounding cars, etc. That is all. And this again relies on the firefighters already being present at the moment the battery becomes a problem. Currently, at this moment in time, anything else is just not possible, and anyone believing anything else is burying their head in the sand and denying the truth.

the truth about electric cars
Correct, we do, but currently there is no effective way of dealing with a battery fire other than to let it burn out, and then, once the chemical reaction has ceased, it can be extinguished like any normal fire. By that time the damage has been done, and very little of the car or whatever remains is likely to be a total loss. There is never any sign of any problems with most batteries, EVs or e-scooters right up to the time that the problem makes itself evident by the off-gassing and jets of flames coming from them. Remember, they reside inside sealed chambers and are perfectly hidden out of sight. The jets of flames are the result of the build-up of gas within that sealed chamber, which then finds any weak spots in the chamber's construction and escapes, all of which add to the danger.
