On V2G, V2L etc..... What Would Elon Do. WWDO
Tesla developing bi-directional charging feature 'many people' won't use. He has spoken and as always, he makes sense out of nonsense. Here are his words. "
“I mean, if you have a Powerwall that can take the house load, then you can use your car as a supplementary energy source to the Powerwall. And then, you’re not going to drive anyone crazy by unplugging your car and having the house go off.
“So I think there’s some value there as a supplemental energy source down the road. Where if you have a Powerwall, you’ve not diminished the convenience of the people in the house.”
Any car can make AC to run a toaster, but all these V2G ideas being passed about have EV power fed directly to the house or the grid, as AC power. The key to a sustainable future is and always will be DC storage. Thats the secret thats missed with V2G.
To become independent of the big power companies you need big home storage and solar. The more the better. Tesla can make Edisons dream of DC powerhouses literally come true. The EV acts as a buffer, a supplemental power to the Powerwall. The bilateral charge could be DC, not just AC, so less conversion losses. Every watt counts!
The car, tops off the powerwall which runs the house, not the car. Car leaves, house has a fully charged battery, from solar plus the EV battery, when needed.
No feedback problems or expensive hardware to prevent killing line workers restoring power to the grid, no extention cords or expensive add- ons, like the Ford solution. The current output is not limited by the cars electronics, its only limitation is the size of the storage and the sizing of the storages DC/AC inverter. Big battery banks with big inverters can output 10, 20kw etc....handling massive temporary surges, if needed. Output current is not dependent on the EVs AC output abilities. The EV can act like a trickle charger actually, with setpoints. 1kw, 2 kw, 3 kW, 5 kw. Keeping the lights, AC, refrigerator etc... running at 3 am when and if the stored solar in the Powerwall gives out. The real technology not being discussed, is V2B---- Vehicle to battery.
Selling your solar power back to the grid is foolish, as Californians just discovered, the power company can pay you peanuts if they want to, instead of 1 to 1 payouts. Keep the power to yourself. Use it. Go off grid....with Tesla car as a backup to your Powerwall, you'll be much better off and more likely to serve the whole via serving the self.
Get a Tesla, a Powerwall or 2 or 3, load up on cheap solar panels and cut the cord. Come on Elon. Do it! Its the only real sustainable future that you have control over. Selling EV power to the grid--- bad idea--- in Vegas, the house (Big power) always wins.
