@Wiggles Australian electricity use in 2020 was 265,232 GWH for the year. That’s 726 GWh / day. If we take 12 h of daylight, during which time solar generation is providing power, (and recharging batteries), we can say we need 1/2 the daily amount for overnight storage, or 363 GWH.
If we say each ev has 60kWH of storage, that means we need 6050 cars, or 18150 cars if we only use 1/3 of the battery charge.
There are 20,000,000 cars in Australia (20 million). That’s enough to cater for Australian daily energy storage needs 1100 times over, assuming a conservative 1/3 of the stored energy capacity is used.
So I dispute your conclusion that here has to be v2g charging points every where.
As per the above, if only 1 in 1100 cars (<0.1%) had a V2G connection at home, that would provide enough for Australian energy storage self sufficiency
Its a fucking no brainer. So why is south Australia the only state that allows V2G connections to the grid?

@Wiggles good pick up. I was out by a factor of 1000. I should have double checked. But even if is not so compelling, it’s still a technology that has the possibility to make a huge impact. EV storage is only going to increase.
There are V2G chargers on the market now, but it’s illegal to connect them to your home outside SA.
There should be no impediment, particularly when state governments start talking about relying on home storage for grid stabilization.
