in an area of just 20km2 I have heard dozens of stories already regarding capacity.

1. My little brother has bought a house last year and intended to get rid of the gas heater but after much debate he was not able to upgrade his 1x25A connection to more than 3x25A, effectively only going from a single phase to 3 phase. 3x35A (which would be needed for an instant hot water unit) was just not going to happen.
2. A mate of mine has a kid that plays soccer, he sees other parents regularly and one of them got a new EV since the company forced it on him basically. He noticed he was charging his car on the electric charger in de parking lot of the sport complex. When asked why "I get bumped into being a business user/account by the power company if I use more than 17000kw per anum and that costs so much that it is cheaper to charge here"
3. That same mate works at a government owned and operated sewage treatment plant and they recently installed 2.7megawatt's of solar in a disused field. The power company has already told them that they are limited to 1.7 since they can't handle it. Since the power company can operate the inverters (switching banks off, which is a requirement with large installations) they can't even use the surplus power to charge their EV's
4. My car mechanic just moved places and the new location has 50kw of solar on the roof, from a time that nobody looked at what they were doing. In order to facilitate the large currents that he can put back into the grid he has a 3x80A connection which costs a fortune. We were looking into lowering the connection to the grid and switching the solar to batteries instead. He has already been warned that he CAN downgrade, but won't be able/allowed to upgrade back "ever" (ie. foreseeable future).
5. And to top it all off, a combination of the two above; a local school (so that is again public money) spend a fortune to fill their roofs with solar, stupidly/naively thinking that they were doing "the right thing" and when time came to hook it up the power company simply said: we don't have the excess capacity in the grid for this, at all, you can not switch it on. This means that the investment is rotting away, there is no solar power to charge their EV's with AND since they could not get the larger hook up to the grid the EV chargers they installed can't even be used since that would blow the mains to the entire school.

These are all stories from people that I know first hand and I have even worked on the electrical setup of half of them, not hearsay. This entire fiasco is beginning to look like a very VERY expensive pink elephant...

Then again, I broke my foot (yeah I know, dumb :P) and my bookkeeper took my out for dinner in his EV renault thingy. As a passenger I am ok with them ;)

Cheers,

Off grid kit and export controls system would have fixed each or most of those issues? My (prior) work was scheduled to be doubled the amount that could be exported. We used 90% saving a lot more than export cents deliberately.

The EXPORT limits are only a issue if you cannot use your own. The School my kids used to go to were confronted by the same issue you highlighted. 5kWh export limit!!! We put 40 kWh on the school and they use all of it 95% of the time exept weekend where it is throttled to export limit. The Hybrid inverters can do that out of the box now easily now.

Back to EV. Looked at a VW Xc40 and C40 this morning. They could tow my boat :) I won't as the solid state from a business largely backed by VW will be commencing production later this year. Add the road noise notes on reviews was not impressive to my hears :)

this thread never fails to deliver the biggest load of bull**** on this website. And that's saying something.

I guess that comes with this subject. There seems to be a direct relationship when I gauge other sites on the web ;)

@NavyDiver

I can imagine a few solutions to that as well but since the export power limitations have caught people out here (naively thinking that anything goes) hybrid inverters were never considered in most cases. Sure, they could probably try and get those but now that the info is out most people won't want to buy the older style :)

Also, my guess is that oz gets a bit more sun-hours a year then we get so have more solar could be beneficial since you wont be putting out the max very often. I mean, with 2.7mw of solar where your limit is 1.7mw you would get to the max early and stay that for longer without al the ups and downs due to changing light conditions. I GUESS that is plus? not sure. I mean, since this is about charging ev's I know I can vary the voltage over my batteries from solar and they will happily charge quicker or slower without issues seemingly. But I am not sure how that relates to EV chargers, I guess they simply want X amount of current from the grid and are not suitable for this style of charging?

A good mate with a BIG Wedding /Winery browns out the entire area due to the power supply outside his sort of rural site. [thumbsupbig] The Wedding /Winery now has a big diesel gen set to power several power hungry cooking and AC units on a off grid circuit as the Grid cannot do it. Its a simple fact that most or many people have similar wires restricting both what they can use at their house, farm or business due to the grid supply and solar export restrictions.

"

A fox type news service has a much more entertaining version of above. The entertaining or total waffle is an opinion of course. Excuse me if my thoughts or opinions upset people. Thats not my objective at all. Debate is fine. Nasty is no fun at all. I have done all the fighting I ever with to do for the rest of my life happily.



Back to EV- Electric Jesus "Tesla Axing Its Supercharger Team Puts The Entire Industry In The Dark"
I used a Tesla superduper charger just once. It was a lot slower than another one not so far away and cost 3 times as much for the power. [bigwhistle]

'IF' as it seems likely that his halo has fallen off now, that may be an interesting area to watch. Same issue will stop electric farm equipment taking hold. Bodes well for copper perhaps.

One thing most don't seem to understand is that superchargers will automatically limit their current to a level depending on how many chargers in the group are being used at one time. If a stand of 10 chargers has all 10 being used then it's likely the max you'd get out of one would be under 100KW as the subs feeding them are generally around 1MW max - some I've seen are half this as that's all the power that's available so it's common at peak times to have very slow charging off the supercharger network.

And who knows how many more they'll actually put in now there is no one in that department to do anything.

The new Port Fairy 50kWh ev charger with two plugs than can be used concurrently, halve the charge rates when both are in use. Well, planned and clearly more expensive places such as "167 Tarcombe St, Euroa VIC 3666, Australia" has a expensive 'power reservoir' and some solar boost or maintain the charge rates. Thats not perfect either! The Mobile Phone reception at that site was PITA to start charging [bigrolf] It says that they are all broken today! "RACV Euroa (2) 350kW DC Ultra Rapid Chargers (CCS2 / CHAdeMO). These charges are temporarily curtailed to a max output of 100kW across the two stations. (2) 50kW DC Fast Chargers (CCS2 / CHAdeMO). These chargers are currently out of order. Both on Chargefox network. On highway side of Shell, opposite McDonalds McCafe Express ordering sign"

That would be as big an issue as reliability of the chargers is clearly not rock solid. The Ballarat RACV ones got vandalized New Years eve. all but one were still broken last time I was in Ballarat.

Seems to be a common issue globally that charging networks are pretty unreliable - apart from Teslas, and who knows where that one is going now.

I thinks Tesla had the benefit of being the first, both in putting EV's in the market as well as rolling out the chargers. When they rolled around asking for a huge electrical connection the power companies would usually shrug and say, ok fine, we have that spare capacity over there for you. If they didn't they'd probably have a discussion as the where the nearest place would be that could handle it.No biggy.

However, now that everyone want more power the grid is already severely lopsided and overburdened it has become increasingly difficult to to make that work...

I await the european summer and am looking forward to see what the route du soleil looks like this year. There used to be huge traffic jams at the shell petrol station in luxembourg for fuel since that was the first cheap spot to fill up and a couple of years ago you would get massive waiting lines at the EV chargers. The amount of EV's had risen but I doubt that the chargers have increased by a a lot in those hotspots on the tollroads. Even if they did, I don't think it feasible to get multiple megawatts in capacity at a petrol station easily :)

-P

And over 4600 EVs from China (mostly MGs) have just been unloaded from the ship into the port of Bristol. - being sold for under. GPB 10k ea 😳 so the UK and Eu car manufacturers are a tad worried about things!

Haven't been on here for a while. Haven't needed to drive the defender. 600km since we got back from the Simpson at the start of Oct. Including a trip to bribie and MR. All our miles that can't be done on a bike go on the EV.

I don't get the people in this thread.

"Ev's are too expensive so are rubbish"

Nooo

"Ev's are too cheap they must be junk"

The grid can't handle it ... they the power companies will have to spend money to make this work. Imagine how much money a supermarket could make if they didn't have to build shops and employ people so they could sell stuff? If they have to put in more capacity it's because they will be selling more power! Which is what they do to earn money. FFS.

Meanwhile I think this will be a good answer for some. Thanks emissions standards.
