Thread: EV general discussion

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. 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. "Electricity bills set to rise as Australian Energy Regulator sets new network transmission cost

"

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.

'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 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

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!
