High Speed Charging

[KickinLeaf]

The LEAF's charging controller tells the Chademo charging station what
current to deliver, not what voltage to apply.

A battery driven Chademo station could be set to deliver "full" amperage,
but draw a maximum of 19 kW, to avoid the demand charge. Then, it
would be able to achieve reasonable duty cycles, if it has enough
battery capacity... until a large-capacity Chademo vehicle comes
along and drains it.

However, the cost of maintaining and replacing the batteries
becomes a major expense.

A home version, with enough batteries to be a home backup
when the grid is down, might be an attractive time-shift solution
(charge at night, and deliver quickly as needed for quick fillup).

Something like this?

That's true, Gary. I was making an assumption that was quite presumptuous of me, since I have no EE training. My assumption was that since I = E/R, and the external charger has little if any control over R, the only way it can control I is by controlling E. Not true? I know, that's not what I said, but I was trying to avoid getting too technical about it. I thought it would be easier to understand the difficult of controlling E dynamically out of a bank of batteries.

The nearest ones to us here in New York are in Ontario and Quebec, unfortunately.

Unfortunately, public access to the sole ChadeMo in Quebec was apparently blocked last week.
