I used to work with a guy that had 12v lighting in his trailer. He'd carry a couple batteries to work and charge them during the day to light his home at night. I never realized how ahead of the curve he was. Isn't this proposal just about the same thing, but with a more expensive and bigger battery? Sure, you can have an inverter that allows your EV to run your house, but you can only do that for so long before you need to drive somewhere to recharge. If you have enough battery to make it to a charging station, and If the charging station has power and space available to plug in...and nobody has chopped off the charger cables to sell the copper. https://ktla.com/automotive/interne...ire-bidirectional-charging-capability-in-evs/
Knowing governments you forced to charge is its expensive and supply if its cheap.win-win power company make more and governments more tax.
Nobody cares about this. The auto makers and utility providers have zero interest in talking to each other. For auto makers it's a useless feature they can add for almost no cost and score green points. The utility providers have no interest in battery capacity they don't own especially after being force fed solar installs that destabilize the power grid.
They might not be as bad off as they have been the last few years ,, with all the folks leaving the drug ridden state ,, and a good majority of them living on the streets ,, they might not have a big demand for power consumption here in the near future .
The problem is powering the line while workers are fixing a break. You can't just be adding power to the grid, it endangers those that work on the grid during a power outage.
