I will talk with the TRC engineer, to see if he feels this would be safe, and then I will buy a set so I can build a prototype, and define some safe ways to tie it into the pack and bring out the charge port on a safe HV connector.
I can make battery fan connectors like I use for MIMA, that will allow plugging into the fan easily.
With the fan running, 350MA will be safe for days and would top off a pack in less than 24 hours.
We could use a simple 240V light bulb as a discharge load, and put in an automatic cycler, so you could leave it unattended for a weekend, and start off the week with a refreshed battery.
Another use would be to grid charge the insight pack with it so you could start most days with a full pack. a mini PHEV.
I just got this report from Allert in Holland: Who rebalanced a really weak pack.
See his users profile at the bottom of this page:

I just want to let you know that my battery is doing fine, I’ve made a trip to the Cote d’ Azur in France and drove almost 2000 miles.
Not one recall and better mileage than ever in the hills in France, battery capacity is what it should be and MIMA is very good in rolling hills. I did 85mpg on the whole trip and managed to get a little over 100mpg for a considerable distance from time to time."
This was after 2 cycles with 250MA
This charger will help cars that are having recalibrations frequently, and some that have an IMA code, but there will be others that will need a stronger cycling at the subpack level to bring them back. This is only for the full pack.
I will post a preliminary schematic on my website before the weekend, and do a blog on how to build it and how well it works. Then we can figure out how many we want to buy parts for.
This will be pretty simple to wire up, and if we stick with the 350MACC, no special components will be required.
A nice DIY project for the technically inclined. This supply will kill you just like the battery will, so don't try this if you are not qualified.
