When we are all EV drivers

Only whist the vehicle is charging or when the vehicle is turned on.

The Natural Philosopher explained on 05/11/2021 :

Building an EV I read, is calculated to be 70% less green than building a conventional IC engined car - then there is the cost of buying and running one. How ungreen is that?

I'm in no position to argue, but I've seen people tearing down EVs, who clearly know about them, saying that's what happens ... might only apply to teslas?

e.g. See the two recent videos here on new plaid 12V lithium batteries

That includes Which?, I quote from the latest article on Green Energy Deals which used the term energy rather than electricity five times before reaching this statement:

"In 2020-21, 40% of the UK's fuel mix is from renewable sources with a further 16% from nuclear power. Some 38% still comes from burning natural gas and 3% coal".

This was part of their response:

"As we are a consumer organization all of our coverage is entirely focused on what is used in a consumer capacity and this is where the statistics in this article came from. As a consumer organization, it would be way out of our scope to comment on the national commitment to

Less green than a modern diesel, if you charge it with German electricity from brown coal ...

Tesla?s (and possibly other EVs) don?t even charge the 12V battery whilst connected to a charger once the traction battery is fully charged.

Somebody didn't read the BMW owner's manual as that states the maximum wading depth of the car. It can be surprisingly small as the air intake is often at sump level. My old Honda CRV (a soft-roader) had a wonderfully convoluted air intake with U bends in it to help stop you sucking in water to the engine. Though it was possible to suck water into the rear diff through the breather pipe if you went through deep enough water. Owner's manual said you should change the odd-ball rear diff fluid if you did that as it would ruin the wet multi-plate clutch in the automatic 4wd system if you didn't. Later models had a very long plastic pipe to try to keep the breather well above water level.

That 3 series in the video must have gone in fast as there was a big black oil slick after it stopped. Possibly wrecked the oil cooler or ripped the pipes of it. Or even the sump pan!

My friend's son hydro-locked his 3 series in a tiny flood. He was tip-toeing through a tiny flooded dip in the road and still managed to suck up water into the engine. New engine was needed as the old one had bent con-rods.

Same here. My car's a Nissan Leaf and it has a solar cell built into the roof to charge the 12V battery. Only trouble is I keep it in the garage so it won't get much charge! My sons suggested I could fit a window in the garage roof but as it's asbestos cement I think I'll give it a miss!

Yes I phrased it badly.

You do not need the second meter:-). It's just the supplier prefers it if you use one.

Assuming you have somewhere you can plug it in to charge. I don't. I am looking at getting a mild hybrid for my next car, but that is as electric it is possible for me to go.

And use the stop over to visit new places - if you not already been then about half way on your journey (depends which route you take?) are the National Coal Mining Museum and Yorkshire Sculpture Park and a Premier Inn just off junction 39 of the M1.

Or if that does not take your fancy I am told there are some excellent brothels on Attercliffe Road in Sheffield:-;

If the second phase gets used, sure that needs to be metered? Yes, I'm sure I could help myself, but that's wrong

Stayed there many a time - most recently in September, en-route to Perth

AC trains can regen - they just feed back into the substation transformer. Unlike DC, there's the whole of the grid as the potential load, rather than just the trains in that section of DC. Like many AC machines, you already have a VVVF inverter driving the motor. All you do is sequence the IGBTs in a different order and power feeds back to the grid - it's just software. UK trains have been doing this for about 15 years.

However, on DC I'm sad that there will be no car-carrying tube trains to Cockfosters.

Indefinitely. That?s how long the jump starters last and it?s the same battery technology involved.

Normal cars need to have their battery

Different battery technology.

It's nothing to do with the battery. It's all the stuff left on when the ignition is off.

But all that stuff is powered by the 12V battery, not the traction one which will hold its charge for months I believe. If you?re not using an EV for months you do need to take care to charge the 12V battery periodically (if it?s a lead acid battery - which I think most currently are).

And what is going to power these bigger substations?

Fairy dust?

Greta's anger?
