Hello JKO I went back through the history of your posts and see that you have been dabbling in a number of areas related to the battery pack, but in total I am rather confused -
1. Did you have a battery failure?
2. Had you tried to replace a single cell?
3. Is your car presently on the road and running?
4. Why the desire to solar charge directly?
5. The 352vdc you identified is a regulated output from a dc-dc converter. Wow, I would be interested in knowing about a power dc-dc working off a very variable source (solar) and outputting a regulated 352v - any links you can provide or is this a homebrew?
6. Do you have a CHAdeMO port?
Both Don and PV1 have identified the constraints of trying to hack into a production vehicle - not as simple as playing with a DIY EV conversion.
While we all appreciate that there is a significant efficiency loss when going from solar panels to a different dc and then from that dc through an inverter to the 230vac you use in Denmark so you can charge 'conventionally', I submit that this is still perhaps much easier technically and preferable to hacking into the i-MiEVs battery pack directly.
