From what Phil told me at the Green Drive Expo, it's more like $4K! Most of that is the charger he buys, which is very high end.

When would you need the 6.7kW charger on a timer? For overnight, for either 80% or 100%, just use 3.3kW. For midday, hit the override and charge at 6.7kW.

Ouch! No wonder it's better than the charger that comes with the car. I have to hand it to Phil for only selling quality products, though. We can hope that prices drop with time.

I don't like to charge past 80% unless I really need it.
But lets say I go to a movie at 50%, and want to get to 80% (but not more) during the movie...

Also, are you saying that the aux 3.4kW won't turn on unless you press the override button?

I don't have any idea how it works. In the movie scenario, it sounds like just using the 3.3kW charger would work there with the timer at 80%.

this is the norm for off the shelf EV components. limited use, limited quantities, etc. means higher pricing. hopefully this will change but right now the DIY EV'er is still a pretty rare breed.

Yes, I know it would obey the timer if I disabled the add on charger.
But what if the add-on charger is left on... would it shut off at 80% just like the on-board?

Using the movie example, lets say I was at 40% and I wanted to get to 80% before the movie let out, but not risk going above 80%...
Then I might want both chargers running to get the charge I need, but don't want the extra charger to keep going after I hit the target SoC.
Maybe not the best example, but my point is that there are scenarios during the day where you could want the full 6.7, but make sure if shuts off after it gets to 80%. Also you won't have to calculate "do I have enough time to get the charge I want with only the 3.3"? You would just run both and expect them both to shut off at the target SoC, and not have to worry about manually turning the 2nd charger on/off.
Sometimes you don't know how long you will be away too. Instead of the movie (which has fairly predictable times) say you were going to a party, and you figured it would last between 2 and 4 hours... 3.3 would be OK if it was 4 hours, but you would need 6.7 if you were done in 2 hours.
You see where I am going with this...? You don't want to be a "slave" to your chargers, you want them to work to your schedule...

Could we put together enough Bay Area LEAFs as a "fleet" that wants the 6.7kW charger to install at a reasonably similar time en mass? What's the minimum number needed for a fleet?

I think what Phoenix is saying is "Could Phil offer a discount if we arranged a 'group buy' opportunity?"

It can be a little tricky to orchestrate. (Probably need deposits to make sure the 'hand wavers' are serious.) Then Phil would probably need to approach the main component (charger) vendor and ask what volume (if any) qualifies for quantity discount...
