I would like to participate in this project, if I may.
I have Gary's famous meter. I have access to a quick charger at Van Ness Station in D.C.,
and hopefully to more, soon. And I have recordings of at least 5 quick charges I can play
back, from charging my Blue 2012 Nissan LEAF, from the Chademo.
If you get as specific as possible about the D.C. power supply, I can cobble together one
of those. I have chargers for my older EV's which might work, if I do not have to output
extreme amounts of power. I have access to 208 three phase at work, if necessary. And
even 480 three phase could be arranged, perhaps.
I keep getting off topic on my posts, but I've assembled a fleet of raspberry pi's with
attached arduino uno's and would like permission/help to try to port Gary's Can Do from a PC platform
to a Raspbian platform, for portability and cost and networking and power consumption
reasons. And maybe upgradeability to the Udoo platform if/when it becomes available.
A pi might fit inside the DC power supply....
I will try to limit my posts to be only about home brew Chademo, but I think we need one
more thread added if someone has not already, to investigate using the motor controller
as a charger, as reportedly done in the Renault EV. Someone needs to make available the specs on
how that is done and see if it is possible to do the same thing in the Nissan LEAF.
My belief is that the high price of chargers and batteries are the two remaining barriers
to widespread acceptance of EV's. It makes no sense for a "Plug", for example, to cost
$2,000 (140 amp Chademo plug), or even $200 (80 amp J1772). Maybe we need an open
source plug thread... Let me stop here before I get too far off
topic again. I just mean to say that I believe this project is what we need most now, along
with do it yourself battery fabrication 101(another needed thread- Open source battery,
and the accompanying Open source battery management system thread).
Back to the home brew chademo project, at hand.
