Reading thru the threads, its generally clear that charging the IMA battery directly is bad because the computer doesn't understand where the extra charge came from and it causes Recal's, etc.

My questions are these:
What if you instead provided a charge (from whatever source... that's a different issue) and your point of connection was spliced into the conductors of one of the regen systems (brakes, transmission)?
Wouldn't it 'fool' the system into thinking it was getting the charge from the inductive system and charge the IMA battery in an acceptable manner?

A possible requirement would be that the electrical system of the car was on.
It might be required to fake the car out that a regen system is 'active' (when its not, if I recall correctly... someone did this with the brake system).

Maybe if you had a wind turbine that would pop up when you're parked? Or even if it popped up if you had a significant crosswind component...
"...fool the stock system into displaying the correct SOC on the battery bargraph..."

I'd be quite happy if it would just drive a different display. Preferably a digitial one that'd show values, not just a simple bargraph.

The more I think about MIMA (waiting impatiently here in the West), the more I've come to think that grid charging might be a practical option. Say you have a 20-40 mile or less daily commute. You could charge the pack at night, and use it just enough to stay in lean-burn mode. Indeed, that might be a future software option for MIMA: have the controller add just enough assist, below some threshold which would vary depending on battery SOC. The idea being that you would try to find an assist rate that gives max mpg over your trip length.
I was thinking along similar lines - if the BCM is powered up, and has incoming current of the right voltage & frequency, how would it know (or care) that it's coming from an external source rather than the motor/generator? So it ought to do all the proper battery control steps. For shutoff, there is probably a control signal going to the M/G to tell it what rate to generate at. Capture that, and when it goes to zero, turn off external charge.

Though I wonder if you wouldn't also need a relay or switch, so that incoming external current doesn't also flow through the motor?
