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).

I toyed with this idea put with form fitted flexable solar cells instead... the enmd answer turns out ... not with the current computer / battery control system... if a replacement were used maybe ... but there is no rerplacement made that does what this one does so you would be making / designing a new one from the ground up... expensive and time intensive.... for home charging the easest thing to do is drive the car onto a a roller of some kind that can turn the front wheels from a electric motor plugsed into the wall... leave car on and in gear and proceed to use the electric motor to drive the front wheels... Insight will enter fuel cut at some point and regenerative braking will recharge the pack.... but other wise you need to rebuild / replace the Insights electronics.

the smallest amount of modification I ever came up with..... of course there are much smarter people than me out there.... but other than the powered front wheel rollers.... you could test the AC characteristics coming from the IMA when it is running in alternator mode ... this would have to include Voltage , Current , Frequency of AC etc..... then use a relay or some type of switch to disconnect the IMA motor / generator ..... connect an outside source of AC that exactly matches all properties tested before .... the car will need to be on such that the electroincs can take this charge as they would from the IMA when acting as a alternator / low power generator..... the unknown is how the INSIGHTS on board electronics will deal with a constant charge when normally the car's electronics could change the IMA frequemcy and other characteristics to change the type and amount of power getting in alternator mode..... as far as I know .... no one has been yet willing to make thier Insight the test bed.....

but many others know more than I do....

I plan to eventually get MIMA and add a wheel motor to one or both rear wheels to allow short range pure EV and and plug in Hybrid operation.... but I am 5 or so years yet from being ready to do my plug in hybrid plans.... if all goes as planed....

best of luck.
