Here's a breakdown of the sections after page 5:
- further description of the IPU layout and wiring
- battery dimensions and cell specifications (no mention of chemistry, which is something I was hoping for)
- IPU heat management - includes a description of the bypass circuit that extends the battery life by ~15% (when the cooling circuit is working on cooling the power components like the DC-DC converter, it will bypass the battery if it is already cooler than the coolant in order to avoid adding heat to it and degrading the life)
- A section on the PCU - includes a PCU specifications table, PCU circuit diagram, VCU waveform diagram (neither are easy to interpret with the text that was given), and a simplistic chart of the improvement in power density over the previous PHEV design
- Conclusions
- References

One thing I found illuminating was the description of the EV battery life extension by using the cooling bypass circuit. It showed a chart of battery capacity vs years (no units on either axis). Clearly it was likely the output of a model, and there was a regular dip/plateau for the curves that eventually depleted it past the "end of life criteria" line near the bottom. When I say plateau, I mean the curve was still going down, but the slope of the line was mild, and for the dip, it was about 3X the negative slope of the plateaus but for a shorter period. The dips in battery life were more extreme in the early life of the battery and very limited by the end of the life.

My assumption is that the plateaus were associated with fall/winter/spring conditions and the dips where most battery degradation was happening was the summertime. I concluded that because the whole discussion in that section was about excess heat degrading the battery life and how the bypass circuit helps. Again, this had to have been a model of life degradation.

Anyway, that was the only thing of value that I could glean from the final 6 pages. If you are someone with an interest in electric circuits and the like, then you may get something out of the PCU section.

They have to increase something because the PHEV Pilot will weigh probably 500-1000 lbs more than our Claritys.

Interestingly, I just found a paper (dated April 2017) from Honda's R&D page that describes a 1.0L turbocharged engine that gets 20% more torque and about the same power output as their 1.8L NA engine, with 26% better fuel economy. Not saying this is the one for the Pilot, but I think it is another option for future PHEVs.
 
Posts 8, 10 and 11 on this thread all reference taking delivery of a Clarity with no or little charge on the main battery. Your dealers failed to accomplish the Honda pre delivery checklist. Mine was the same, delivered with no charge on the battery.

There is a document floating around somewhere on this website that details the things a dealer is supposed to do before delivering a Clarity. From my own experience and reading the experiences of others here, the two most common failures on the part of the dealer are failing to charge the battery and not installing the 4 body plugs that come with your vehicle.

The body plugs seal up holes in the car that it is thought are used to secure the car to the trailer during transport. Without the plugs, the car can be noisier then intended. This, too, can be researched on this forum to see photos of the location of the plugs to check your cars. If your dealer didn't charge the battery, I think it's a good bet they failed to install the body plugs, too.

Dropping that torquey turbo 1.0L triple into my Insight would turn it into a rocket!
