facing some reality on EV charging requiring electricity that might not be available thebfd.co.nz/2023/07/29/evs-are-a-bit-shite-31/"Queensland risks putting the brakes on the transition to electric vehicles if a state-owned energy company is given the power to switch off home charging stations, according to the industry body."
Or, to put it another way: Queensland is making the “mistake” of telling just a bit of the truth about EVs.
Namely, that when EVs reach a critical mass, the power grid will collapse under the strain of trying to charge all the damn things when people are trying to charge them at the same time.I think controlling the demand of EV charging is perfectly reasonable. It is the same as controlling the demand on hot water cylinders. Strewth, we even have the technology in NZ, including several systems in operation, where we control your wastewater flow off the property. We can even stop all flow if we want. It dramatically reduces the cost of the infrastructure, and avoids overflows into the environment. Most EV drivers don't need their car to start charging when they plug it in. They just need it charged before they go to drive it again. In the case of commuters, when they get home (lets say 6pm) is peak power demand time. Everyone is cooking dinner, turning on lights and heating etc. It would be very easy to set up a 'smart' power grid with IoT linked EV charging sockets at each residence that lets the car charge after peak power draw, i.e. from 11pm. Infact, you can get a $10 electrical timer from the Warehouse (10amps) that would do that now. This is incredibly easy peak load shifting. It would be a complete nonsense to try and provide peak generation and transmission capacity to meet that. More so, all of Queensland's power comes from coal I believe. It is very hard to ramp up and shut down those turbines quickly, like you can with hydro. So shifting baseload consumption (EV charging) to the 11pm to 5am period would dramatically improve overall efficiency. I don't see the issue with this, other than people's lack of understanding of what they are dealing with, and how infrastructure works. |

Quite correct Fishy re Queensland, and for that matter all the rest of Australia (except SA with its unreliables, Tassie - hydro and NT which doesn't count anyway) currently generating the bulk of their power from coal. The problem is they have bought into the climate cult big time and are progressively closing their coal power stations without any replacement baseload generation coming on line, just more unreliables. So that small hours surplus may soon not be available for EV charging or anything else. |

The paradox with the growth in unreliables is that the power co's are going to need even more control over the EV charging to manage demand. If the wind is blowing, charge your car, if its not blowing, it ain't going to happen. |

So when do shift workers get to charge their EV? I and many others leave home at 11.00pm Between 1.0am and 3.00am you would be surprised at the amount of cars using motorways around Auckland
When I leave at 11.00/11.30pm and travel my 13kms to work its like a mini rush hour.

A person is in a critical condition after a scooter battery exploded in a central city apartment with enough force to crack glass and move furniture. Crews were called to the Tory Hotel at Century City Apartments on Tory Street at 5.30pm on Saturday, Fire & Emergency incident controller Mike Dombroski said. There was a fire in an apartment on the first-floor of the building, caused by an exposition in a lithium-ion scooter battery which was being charged, he said. One person was taken to hospital with critical injuries. www.stuff.co.nz/national/wellington/132644522/scooter-battery-blast-moved-furniture-cracked-glass-left-person-critical |

The grid stuff is a bit alarmist, networks use to say that about heat pumps. It is a temporal issue i.e. it gets resolved through time.

The Wa is sussing for a new ride. The options are not huge, horrendous priced petrol or horrendous priced battery and the odd freak in-between. We could do petrol, can't do charging so battery is out. But prefer diesel as everything else we have uses it so we can recharge on the farm. Also not that many smaller wagons that seem rural friendly, most look like they would struggle to get across a golf green.
What's a good wagon to suss? Preferences are mid sized, diesel, she may go hybrid, will handle dirt roads well, isn't red, doesn't go BING, BONG, DING every 2 minutes, doesn't need an App to operate.

The problem with small diesel vehicles to remember is their damn DPF's (diesel particulate filters) that seem to be forever getting clogged if you are not doing lots of highway miles. Mazda diesels are exceptionally bad for that and most European diesels not much better. If you are still keen on diesel how about an AWD Hyundai Tucson/Kia Sportage, same running gear and seem to have a pretty good reputation. I have friends who changed from BMW's to Hyundais. |

Not going near Hyundais, the NZ principal is an arse and behind the closure of The Landing.

Chatting to a car dealer of size last week and he reckons the uptake in EV's is 90% between the subsidies and the other is lack of options, 10% genuine desire to have a battery car.
When you suss around, as we are the options are small CC with turboed petrol all pretty much the same as the next or battery. When the guts of dealers sales pitches are 'It has a 8" screen and you can get it in metallic chartreuse colour' you know you are selling very generic.
As the Wa can't find a nice smaller diesel she is now seriously considering a double cab ute. I think we've run into the Law of unintended consequences again.

comments from BFD Meridian have started charging to use their network of AC (ie slow) EV chargers - the tariff is 50c/kWh which is generally being viewed as "fair". Their DC chargers have always had a cost attached to them, which is somewhat higher in recognition of the convenience a faster charge brings.
This is spectacularly good news - it blows the whole "Drive an EV and save money" argument out of the water if you look at the actual numbers involved.
EV costs - The Tesla Model 3s at work are apparently doing 5km/kWh which works out at $100 of slow AC charge to travel 1000km, plus another $70 of RUCs from April, so $170 in "fuel" costs.
Hybrid costs - The Corolla Cross Hybrid I have been punting around for the last 10,000km or so is sitting just under 5l/100km, so to travel 1000km will use 50 litres of fuel at around $3/litre giving a cost of $150.
I wonder how long it will take for the smug to disappear from the faces of the EVtards, especially as they will have shelled out $20k more than the Corolla cost for the Tesla.and One needs to also factor in the insurance costs for both EV and house if the EV is kept and charged in an internal access/attached garage.If the EV fires continue to increase I can see Insurance Companies raising their EV and house premiums significantly as they have done for the fake climate change predictions.meanwhile, yet another EV battery fire www.drive.com.au/news/mg-electric-car-battery-catches-fire-sydney-airport/ |

Is it true that the Nats are looking at scraping fuel tax but instead each vehicle will have eroad fitted and you pay per km??Then a weight factor up to 2 tonne and up it goes?
