Power walls can send power back to the grid, you just have to program what conditions you wish them to do that in, or like agl does they can be controlled by a third party.Yes they do, I haven't looked into it, but I doubt they work in unison with other charger/inverters, that is when a power failure happens the power wall probably islands itself and runs that house.
The issue that i'm talking about is when the cars are being used as storage for the grid, which is a whole different concept, in that situation the cars would stay connected to actually maintain grid security.
That is a massively complex scenario and actually may not happen, but my guess is it is being investigated as it would make a massive difference to how much storage the Government and industry will have to install.
The other issue is what smurf alluded to in post #3,269 above.
To expand on that - the third party is in practice overriding the Powerwall's own process of matching output with house load. That is, changing its output to something other than what it would naturally be.Power walls can send power back to the grid, you just have to program what conditions you wish them to do that in, or like agl does they can be controlled by a third party.
More on some of the issues I was talking about, in this article:The car isnt the problem, the issue is the charging equipment has to be able to handle two way flow and work in unison with all the other chargers, or they will melt down.
The car is just the battery, the charger will have to be a charger and an inverter that can control discharge rate etc. It is going to be very interesting and we are at the very beginning of the journey.
One issue i see is the battery designers want to build batteries for continuous charging when parked then discharge during drive aka charge under temp.etc settled along a few hours with usually multi phase charging to extend life of the battery and components.More on some of the issues I was talking about, in this article:
From the article:Jemena to lead wall charger trial to allow networks to control home EV charging
Jemena is to lead a trial of “smart wall chargers” across three states to test how networks can “dynamically” manage charging of electric vehicles at home.reneweconomy.com.au
Jemena is to lead a trial of “smart wall chargers” across three states that will test how networks can “dynamically” manage charging of electric vehicles at home according to supply and demand.
The $3.4 million trial will involve more than 170 households across Victoria, the ACT and Tasmania, and the network companies AusNet Services, Evoenergy, TasNetworks and United Energy. It is one of a number of “trials” being run across the country to test how EV charging fits into the transitioning grid.
The Australian Renewable Energy Agency (ARENA) will pay $1.6 million towards a program that tests “smart” electric vehicle charging technology that is faster than standard home chargers and responsive to grid demand.
It isn't a case of will they follow through, we import cars and the world's car makers are changing over from ICE to BEV, so it is a case of we will have to transition to BEV's that's all that will be available.Federal government being dragged into an electric car future.
Just a "discussion paper", will they follow it through ?
End of the 'war on the weekend' or beginning of an auto revolution? Government shifts on electric cars
It's two years overdue and the details were leaked months ago, but the Federal Government has finally released its plans for supporting electric vehicles.www.abc.net.au
Haha I love this guy.
He does a good job at summarising the technical, political and practicality of EVs
The funniest part about the video is that he is a petrol head, that finally realises now that EV’s are better and more convenient, however he still doesn’t want to think of himself as being part of the EV crowd that like the environmental benefits, so he builds a strawman argument against the non existent EV environmentalists that think EVs are carbon negative.
EV owners don’t think that just because they use an EV that their entire life becomes fossil fuel free and carbon neutral, so his whole rant about that is silly.
