Now, I haven't found _any_ info on grid charging or reconditioning one of the 100V batteries. These things have been on the market since 2010 so I find this quite strange.
Does anyone have any experience or pointers regarding the 100 volt Honda IMA batteries? Any reason why I couldn't just use the principles laid out by 99mpg.com for instance? What I want to do is install a grid charger.
Also, are there any feasible ways of testing the current health of my battery, or monitoring it with some sort of an external measurement device? The "instrumentation" Honda provides is disappointing for an engineer.

Will work fine except one of the 48V PS will likely cycle in and out. I'd use two of these:
APC-35-350 Mean Well | Mouser
The LED supplies regulate their voltage and supply 350mA. That will give you 112 to 200V. With 84 cells in the pack, you should expect a peak charging voltage as high as 124V (1.475V/cell).
If you leave the pack in the car for grid charging, you will likely need to devise a PWM controller to drive the fan. HCH1 and on are PWM fans. I would assume the Jazz is as well. If you remove the pack, a simple box fan blowing through it will suffice.
The Jazz uses essentially the same system as the G2 Insight. Hybrid Automotive looks like they may be developing a charger for the Insight. I would expect it to adapt to the Jazz readily.
Regardless, the bulk of all information concerning grid charging/discharging IMA NiMH batteries would apply to the Jazz except scaled appropriately for the lower number of cells.
