Any progress Rick? It's been a long time since your last post.
I don't hypermile my Prius, so without the booster running I only get about 42-45 MPG. In fact, I drive it fairly aggressive. The booster I run now is a complete B3 kit from Hydrogen Garage, with the current regulator set to 5 amps. The system is wired up to my hybrid drive system so that the booster is on only when the engine is running. The B3 is so small that it can be installed in the drivers side front fender of the newer Prius models, but in my older NHW11 Prius I put it into the passender side rear fender - opposite of the 12V battery.
I did a plug-in mod on my Prius for a while. I had added a couple of used NHW11 HV battery packs and a switching interface. I charged those added HV battery packs from solar power when I was parked at home. Problem was, I travel too much to rely on the solar charging at home. So I removed the added HV battery packs and went back to just the single original factory HV battery.
I then built a HV version of my toroidal system for the factory HV battery. It sends charge all of the time, whether I am driving or parked, I really need to set up a SOC monitor to shut down the charging when the HV battery gets up to around 95% SOC because it will overcharge if I do not shut it down during extended parking. The higher voltage of my NHW11 HV battery as compared to the newer model Prius HV battery makes messing with this a lot more dangerous.
