Random Irritations

Probably should ask this on the electric car thread, but here goes:

I can't understand why using accessories in an EV seems to consume so much power.
The lights are all LEDs, right? So even the headlights are probably no more than 50W. Let's say with all the lights on you're consuming 100W, so it'll take 10 hours to use 1kWh.
Now add the heater: I'd guess that's about 1kW, so in an hour it should consume 1kWh, which is only about 3 miles of range.
All of this is surely negligable compared to actually moving the car itself.

I think accessories are powered by the normal 12 volt battery which can go flat quickly if accessories are being used when the car isn't moving.
A battery warning notice flashes on my diesel car if the radio or lights are on for too long and the engine isnt running.

Reading some of these posts today has made me feel really disappointed that nobody knocked on my door last night. Did not get the chance to ignore them.
Maybe next year.

Got called a grump by my missus for not taking my 2 year old trick or treating last night .

My mum always likened it to begging so I never did it as a kid but I do find it somewhat ironic that you spend your parenting life telling your kids never to take sweets off strangers but then dress them up and tell them to do exactly that once a year .

My Mrs has been asked by work to move from using Chrome to using Edge. Now that’s fine, except Edge doesn’t work but default the same way as Chrome for one very simple but essential aspect of her work. She has to copy web address URLs and paste them into a Word doc - sometimes formatted as a hyperlink, but also sometimes as the URL ‘text’. And guess what… Edge has a ‘useful’ new way to copy and paste URLs by default in that it pastes a URL as a hyperlink.

Happened to my Mrs this morning for the first time and she hadn’t a clue what was going on and got completely worked up and upset over it - and as she works remotely (and away from home at the moment) she feels really stupid and ends up calling me for help. Until we did a WhatsApp video I hadn‘t a clue what was going on.

As it happens as soon as I saw the hyperlink I recognised it for what it was and guessed what might be going on so was able to sort it out. She could see it was a hyperlink but had no idea what to do to paste the URL.

It’s hugely frustrating and irritating that her work did not point this out when they were asked to start using Edge.

Yes you are probably right . I looked it up and the best I could ascertain is that the headlights are 11/20 Watts (plus rear light wattage)

Like a petrol car moving the car about 3 cars lengths stop on regular basis in a traffic jam situation last night and it is uphill virtually all the way to Tesco was probably a major factor (you still have to overcome the inertia)

My problem yesterday was mainly about getting to club and back and for which I had enough power but doing it twice was possibly going to push the meter in to the red which another user with same vehicle told me to avoid doing.

Looking it up - In an electric vehicle the lead acid battery gets charged up by the lithium battery pack (there is no alternator)

I am learning more and more.

Kids nursery photos

52 photos to pick from. Just want the USB tbh but do I get a choice of photos? Nope

£65 for the lot? There's only about 10 decent pics

Any proof not returned £4 fee

Oh do jog on you scammers

Don't mind when it's reasonable costs but £65? Best not try charge me twice for being two of them .

You're thinking of the English version I think. In America it's pretty much just become fancy dress I think.

The key (btw there is no ‘English’ way ) is that you don’t want to be recognised, and so…if you are not in witchie, ghoulish or ghostie garb, you should be dressed up in disguise…with a bit of scary make-up or face-painting - not just in fancy dress. Disguise is key…

(says he as if he is a spurt and knows about these things and that there is a ‘way’ )

I still don't understand why an EV needs a lead acid battery at all. Why don't they just power the accessories from the main battery pack via a voltage converter?

Tesla are working on using lithium 12 volt batteries however 12 volt batteries are still apparently needed

Why Do Fully Electric Vehicles Still Have a 12V Battery in Them?

It’s not very common to hear about a 12-volt battery and electric car. Most have one, but it begs the question: why?

www.midtronics.com

"Can’t the high-voltage battery be used instead?
It would be extremely expensive to convert all the tech inside a car from the widely used 12V systems to parts that convert from a higher voltage. It’s also impractical since there’s a simpler solution already in use. Not to mention, the 12-volt lead-acid battery powers a critical safety component – the contactor – that disconnects the high-powered battery in the event of a collision.

While it’s technically possible to work around it, there’s no pressing need to replace the current design."

I come to go to bed and the hound, who has already been out several times during the evening, stands by the back door as a way of telling me he wants to go out again.

So I let him out into the peeing rain and off he sets like a juggernaut down to the bottom of the garden and stays there, barking away at the moon, rain, or paper bag blowing round in the wind. After ten minutes waiting for him by the back door I've given up and poured myself a whisky.

Five minutes later the daft sod is still out there having a bark....luckily we have a very long garden so he is quite a long way away from our house or the neighbours.

Of course you don't want to have every 12V accessory need to work off a higher voltage and do its own conversion. That would be daft, so I can't understand why they even wrote the highlighted sentence.

Every EV must already have a voltage converter - it will be needed to recharge the 12V battery. Why can't that just be used to power the accessories and cut out the middle man?

There must be some other subtlety that the article you quoted hasn't explained.

One of our Springers is a total mudlark. He absolutely loves racing across muddy fields and jumping in big puddles.

He ends up getting hosed down after every walk as he is always filthy.

Yet if I let him out the back at night, he refuses to put his feet on the grass if it's wet.

Dogs, eh?

Be careful if you’re sent a link to twitter/X today, some sick guy left his phone in a pub and those who found a video on it and it’s currently going viral. It’s terrible.

One reason I suspect but have no real knowledge of is when the car is being worked on it is possible to isolate the battery pack for safety* so the 12v lead acid battery will maintain systems such as the computer, door locking etc

Bearing in mind that the battery pack is used to generate a voltage in the range 400-800V depending on the vehicle.

It pains me to say it but...Bake Off. Caught up today. Another favourite gone and the cry babies remain. Get a flipping grip!

Yeah the tears are getting annoying. Still, at least the format is better now, no ridiculous weeks and more set up for people to to win because of how they succeed than win because of how little they fail in comparison.

To be fair, cry baby rather than babies. There is only one giving it full water works, and yes it was painful.

Mind, I loved the buns round . I might have not been able to walk after eating all the ones I fancied.

I'm not sure there is a nailed on winner this year. Dan is good, Tasha a good but neither smash it every week. I like that, anyone could win now.

I think Tasha plays on the emotions. Migraine one week. Can't say the words this...terrible technical, rubbish show stopper yet in line for start baker?! What...

Parcelforce....
When you pick up a parcel and return to the Birmingham depot to put said parcel on the trunking vehicle to the hub.....make sure it gets unloaded at the other end so it can be sorted onto the trunk to the delivery depot.....rather than leave it on the first vehicle and take it back to Birmingham.....
Really, it ain't rocket science......

The parcel, at the 2nd time of asking, made it through the system and was due to be delivered between 11.20 and 12.20....
Tracked the van and he was in the vicinity around Noon.
No van, no parcel....
But, apparently, at 11.57 I refused the delivery.....and I would do that because.??
Evri, Yodel, UPS and now Parcelforce.....all as bad as each other.
Their sole reason to exist is to deliver parcels..all bloody useless.
