Re: New BBC soap: Bert Coules?

You also need to take into account cooling and transission

But essentially I am saying yes, the small engine and the 'large' electric motorr plus battery will be less or similar to tjhe large engine in a typical car

You would be surprised at how small a 200bhp electric motor can be.

Because you will need to remove thenm to sell te house

Tectonics and vulcanism account for far more 'local' seal elvel variation than ocean temeperature does.

TNP getting it wrong again, I have already stated the sensors are in the car but he choose to snip that in the hope nobody would notice he is a liar.

They tend to charge extra if you want to be able to connect a fast DC charger. They charge a fortune for what is about £20 worth of sensors.

If you saw them you wouldn't recognise them as solar panels.

They are a bit dearer than the normal type, but they are used on listed buildings because they look like a traditional roof. Marlborough College is roofed in a mix of real slate and solar slates and you can't see the difference.

There is a large new "village" called Buckshaw near Chorley in Lancashire.

I'm delighted to hear it (and brightside's post too).

I presume they're a bit dearer as they have to include roof structure as well as just the solar panel bit.

I thought there were basically three sorts of charger - standard, which used up to 13A and was for overnight; "fast", which was about twice that (7.7 kW seems to be a popular figure, for some reason), and about 4-6 hours; and "rapid", which does 30-60 minutes. (Plus some even faster, but possibly only for Teslas.) [Obviously those charge times are just a rule of thumb - they'll vary for different cars/vehicles depending on battery size, and of course also how empty it is.]

I thought for at-home use, the standard charger involved plugging the car into a normal 3-pin plug, not needing any fitting of equipment (provided you had a suitable socket somewhere), and that the sort you paid to have fitted were the "fast" 7.7 kW ones (and that the really "rapid" ones weren't feasible on a domestic setup, only at places like motorway service stations or petrol/diesel outlets). With the "standard" ones fittable at kerbside - with, presumably, a different connector if only to stop people plugging anything in - by local authorities, often using existing "street furniture" like lampposts. With the option of "fast" too (but not "rapid").

I'm assuming the charging (of money) you're talking about is what the various companies (I think there are about a dozen approved ones) charge a householder for fitting a "fast" charger. And again, I assume most of the cost isn't for the charger itself - your 20 quid might be right there - but for the extra work, extra circuit from the distribution unit, digging, cabling, and so on.

I think there's government grant available for both home and work fitting of these. (Not the whole cost, but some of it.) I think you have to provide proof you _have_ an EV of some sort too (not sure if hybrids count - they certainly should). I haven't been able to discover anything similar to help local authorities - e. g. parish councils - fit the "rapid" chargers; I understand the cost of those is about 10-15k all in, including planning applications etc. and all works, i. e. a "turnkey" solution - with the alternative that some of the installation companies will do it for free in return for a ten-year lease and collection of all revenue (the electricity is sold at above cost price), with various permutations between (paying full cost up front and paying nothing). They'll even return a revenue (to the local authority) if desired - that's done by upping the cost of the electricity by a few more pence.

No I didn?t. The engine was fine and in fact I sold it to the local VW dealer whose son wanted one and drove it for decades. I kept seeing it around for that long.

You're wrong there too. I did in fact use it in just those situations where the temperature routinely gets over 45C most years in Australia.

Because they arent as viable with the higher horsepower engines and few modern cars have the engine in the back of the car like the beetle and kombi do and those flat 4 engines don?t work as well with the later FWD EW engine gearbox combinations that give much better internal car body space that took over from the beetle shape.

Thise are not photovoltatic panels, dear. They are hot water panels

Guilty your honour! There are solar slates that generate electricity; that is the type fitted to Marlborough College, though not necessarily this brand:

Jim

No I am not. Its the sensors in the car. Some cars have the DC charger as an option and it costs thousands extra. I was going to quote the Renault Zoe as an example but the latest models include the DC option while earlier on they didn't.

You can get a 32A charger wall box free from just about any electric car seller if you are buying new.

There is nothing in them except maybe an RCD/ELCB.

The charging control is in the box fitted to the cable you plug in the same as for the 13A cable.

Thanks both. So built-in rather than bolt-on-top ones _do_ exist, though are currently rare.

(Another thing that seems odd by its absence is any triangular ones. I see lots roofs with several rows of rectangular ones, with the obvious coarse quantisation at the ends of the rows.)

The hot water ones - especially with heat pumps/exchangers - seem not to be getting enough attention, especially if we're going to be encouraged to move towards electric heating away from gas.

By "DC charger", do you mean higher (7.7 kW?) power one? Or what is needed to connect up to the "rapid" chargers that look a bit like a petrol pump, at motorway services and the like? I didn't realise all EVs didn't have the necessary for that; might explain why I've hardly ever seen anyone using them, if they can't.

So the car's own charger for "standard" (13A through a plug) and "32A" is actually the same unit in the car, is it, and just takes a different amount of power based on some signal it receives from the connector to tell it which it is connected to? (I presume the "32A" charger is still connected to the 240VAC mains [or 220].) Do the sellers arrange the installation of this wall box? That sounds like something I wouldn't imagine the authorities being happy with the average punter even attempting.

There are multiple standards, but the popular one for AC charging is a "type 2" which has a D shaped plug, using L1,N,E and two control pins, plus optional L2,L3 pins for three phase (obviously not many houses have that, and not all cars support it either).

If the car supports DC charging, there's an additional connector with 2 larger pins below and a "combo" cable is used, this shares the E and control pins with the type 2 AC socket.

So is this right, for the UK: notional nickname power charge time runs from comments

-------- ----- ----------- --------- -------- "basic" or ~3kW? overnight single-phase in the home, "standard" domestic mains normal 3-pin (BS1363) plug

"fast" 7.7 kW 4-6 hours single-phase needs special domestic mains fitting for home use

"rapid" tens 30-60 ? service stations of kW minutes and the like

with the "standard" and "fast" also fitted at some kerbside and workplace installations (with different connectors for "standard", i. e. not just a BS1363 ["13A"] socket)

Am I right that most EVs can use the above three (possibly needing connector adapters)?

then assorted higher-power (speed) systems, of decreasing compatibility both of car-compatibilty (circuitry) and connectors?

yes normal 13A plug

generally a dedicated 32A circuit and wall mounted charging box, could also be three phase if house and car can manage it.

for cars that support DC charging, and generally will only go to 80% on rapid charge.

maybe a 'commando' outlet?

For europe yes, better standardisation than RoW (chademo, type1, telsa proprietary, etc)

Thanks

I don't think most houses have 3-phase available. What advantage would

So is this always DC? And what proportion of cars _can't_ use them?

So most _can_ use even the "rapid" chargers?

I'm more than a little confused: do the terms "rapid" and "DC" refer to the same thing (in both what's in the "station" and what's in the car)?

correct.

sqrt(3) times the power, compared to single phase

Yes, some cars can take up to 32A single phase, others only 16A so not much more than via a 13A lead, but unless you have good quality 13A socket with nice tight fitting connection, dedicated charging point is safer, e.g. some can monitor temperature within the connector and stop if it overheats.

A lot of local distribution in towns is done on two phases of a three-phase system. The local feeders to various streets are distributed among the three phases of the supply transformer, but each cable only carries two phases and a neutral.

In some rural areas, the pole-mounted local transformer only runs from one phase of the overhead 11kV line but uses a centre-tapped secondary to distribute the local supply as two phases 180-degrees apart.
