Appears Quasar is on the right track.
A major issue is - can it be used to supply backup/emergency energy when the grid is down? - doesn't appear so.
I posted this in "TMC"
I'm in Vegas for CES. I spoke to these guys at their booth yesterday.
It's not shipping in the US yet. They told me that it still requires a connection to the grid. It won't help in an outage in its current form. I mentioned I'm PG&E-land and already experienced two "PSPS". The guy told me the reason is that if you have no grid power and let's say you turn on an oven. Suddenly, there's a huge jump in demand and CHAdeMO doesn't let you do have that sudden sharp increase. I don't recall if the words he used were that it has to be a ramp up or in steps.
It's something they want to work on addressing. I recall him saying that many folks either wanted the outage protection or mention PG&E PSPS.
So, for now, it's only useful cases where you might want to store power from the grid at cheaper rates or use during more expensive periods. Or, (IIRC), it can be useful for those who want to store excess solar energy.
