I can well understand charging one's battery from solar and wind power....or sorry, rather, I can't, because solar power is surely not going to be quick enough to charge a car up. -probably not wind power either.It's urgently needed with the increasing share of solar and wind power.
Isn't it the other way around? Malls and stores have electricity jacks for charging an electric car that parks there, not to steal electricity from it.
But electricity is cheap. The jacks for charging electric cars are not bi-directional. The stores make a HUGE profit on everything they sell so the charging jacks might attract more customers to go there and buy their products.
Why does the power grid go down? My part of the world is civilized and power outages are very rare. Maybe bi-directional jacks can be used where they did not design the grid properly so they have "load shedding" frequently.
At first I was dumbfounded that anyone would push people to discharge their car batteries into the power grid. But I just found a web article pointing out that an electric car could power an average home for a day or two.
This creates possibilities (per the story in post #5). Suppose people really could make money by charging their car during off-peak hours, then parking at the mall to sell electricity onto the grid at a higher price? Then the idea starts to make sense.
And it's primarly intended as a grid stabilizing means
It will sell, it's just IMO that the owners of electric vehicles will get short changed. I can imagine going to your mall with a nearly full charge and coming out with half a charge because the bi-directional car charger decided it needed to help "support the grid".So why is anyone even contemplating making bidirectional car chargers? Someone has just asked us to design a 7kw bidirectional, mains isolated car charger for them. I think we should go back and tell them its a nice gesture, but could we take their money for something that is never going to sell, and even of it did, nobody would use it?
I am not saying its not a good idea for the country, etc etc.
No I was basically saying it is unfeasible for consumers but very feasible for industrial users with high peak to average power consumption and pay for an entire month based on their peak demand. Which can result in significant savings.
