Thread: EV general discussion

Thereis an article on the internet today "British MPs protest Mandatory EV introduction"
It seems Boris's woke girlfriend has been buzzing in his ear and the rest of the government may not agree.
Same with phasing out gas heating of houses in UK. They just realised it will cost 10s of thousands for each house and the electricity system also will not cope. Whoops.

I'm not having a go at you or anyone, but this is clearly the way the world is going.
You're spot on the grid isn't ready yet. The point is the planning is being done to change the grid, connect it better and build many new renewable generators with storage. ANEMO is planning for the grid to be net zero emissions by 2050.
In 20 years time today's arguments are likely to be regarded as quaintly outdated.
It's interesting to watch how this revolution is happening.

I’m not anti EV - it ****es me off no end that people think this when I try and point out the physics of charging mass EV’s when I work every day with the grid all these people think will cope no dramas when it simply won’t.

It’s not my opinion, it’s not me being anti renewable or anti EV - it’s just the facts when you look at how the system works and understand it at a fundamental level not just what you can glean off the internet.

Science is the new frontier to hang it on so Engineers that design, build and maintain these systems - who believe me are looking for solutions - just get told we’re lying to the population. I just don’t get it - don’t believe me if you don’t want to but the facts don’t lie - there just isn’t enough power or a way of getting it to homes currently to charge EV’s on mass. Work out the energy potential of petrol, what the electrical equivalent is then work out how much power is needed to replace say half the petrol with electricity - the numbers may surprise you.

Not having a go at anyone in particular but the numbers simply don’t add up - no system in the WORLD can cope with mass EV charging without an expenditure an order of magnitude higher that what is being spent - and no one will accept power prices in the dollars per KWh so what’s the solution?

I don’t know but everyone having EV’s isn’t it. There’s just not enough money to go around to make this work.

Thanks goodness I’ll be close to dead by then.
I better organise a burial, doubt there will be enough power for a crematorium- unless it’s a solar oven


Seriously though AEMO couldn’t organise a **** up in a brewery.

Nobody is going to want to wear the pricing the enormous grid upgrade will require, not the ongoing R&M on batteries, blades, panels, structures.

I might sit down some time and work out using current data, the energy requirement of our mine fleet. I’m pretty confident it’s going to be big!

I got rid of my overnight 15 amp 11pm energy soaker HWS, for a 5 amp run during day (when my solar system is being useful) Heat Pump Hot Water System.

So my simple minded theory is I have freed up my overnight use to charge my non existent (well, until I fit hub motors to the disco) lektrik car.

A few more doing this (and it is happening with solar uptake anyway) should help somewhat ?

Yep, once you have solar, the trick is to move consumption to the daytime and minimise night time demand.
We have solar hot water, so that's daytime.
With hindsight, we would have been better to have installed a heat pump and spent the extra money on more solar to power it.
You learn with time.

I cannot remember the forum member who has one on order.

However I believe I predicted many months ago that it was "vapourware".

i wouldnt go near a heat pump,we fix them regularly.
Continual repairs are not uncommon and often expensive.They are also complicated compared to the mainstream HW units on the market.
Although a longer warranty will help.
A solar HW or old school with a heater will outlast them by a huge margin.

We have had solar HW at this place for 20yrs,and the last place for 22yrs as well.
And thats with no maintenance or repairs,apart from cleaning the panels annually.
Although at this place in winter it is shaded by trees,so we have to use the booster very occasionally.
