One could be wound for the lower voltage of the newer model 168 cell HV Prius battery (nominal 202V), similar to the one I wound for the older model 228 cell HV Prius battery (nominal 274V) in my Prius.

I am not taking on any more independent evaluators for testing prototypes of my toroidal charging system. This is due to several information leaks from members of the earlier evaluation group. Leaks that did not help others to replicate the board design due to specialty component specifications that were not shared with the evaluators. However, I might consider a "black box" type of test for a Prius setup, where the board is sealed in a faraday cage, potted in epoxy.

Cost is relative, as the cost on my earlier prototype boards worked out to be about $300 per board due to the specialty components required. It was amusing to see those that attempted to copy my board, comparing the design to a simple $30 PIC or Arduino board. They found out otherwise when they failed.

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.
