Yes, Ben has agreed to share more photos of the HVDC connections and contactor on his raspberry i-MiEV, but he's been pretty quiet for the past month. It did have CHAdeMO, and I have dibs on that hardware!
You can see him removing the HVDC cable connections in his YouTube videos, but it didn't show the contactor. http://www.youtube.com/watch?v=7KhGJNn4 ... g&index=17
Thanks for checking the CHAdeMO pin voltage, PV1. That wouldn've been too simple an answer, but was worth checking.
A DPDT HV contactor is one possibility to explain the single contactor. I've never seen one- though I do have a monster DPDT for motor reversing.
Don, no I wouldn't put 50 kW into a retrofitted ChAdeMO port right off, as I only have control of 4.8 kw at 330 VDC, and the uncontrolled jumper cable "DUMP CHARGE" technique using Andersen PowerPole 350's is not for the faint of heart.
But I have pulled up to 22 kW out of the Range Trailer while feeding the Karmann Eclectric between races! http://www.facebook.com/pages/The-Range ... ref=stream
(It's got 200 AH at 360V of ThunderSky cells feeding a Manzanita PFC75 charger.)
Provided that the i-MiEV is turned on and charging current is input upstream of the current sensor, is appears that the car couldn't tell the difference between heavy regen and an offboard current source, and would accept it normally, though not be able to cut it back automatically. (Unless that meddlesome little silicon brain is also looking at motor speed, wheel rpm, selected drive mode, or a dozen possible other conflicting inputs.) I won't hook my i up to HVDC of any flavor until after much more research!
