I was looking for a way to add solar cells to the roof of my escape to increase battery power because I think it is a much more efficient process then a full PHEV kit.

I think the escape would be a better canidate for this type of technology vs a prius due to a large roof area for more solar cells, and larger trunk space for a greater number of aux batteries in series to take advantage of the solar cells.

Then I came across the following page http://eng.usna.navy.mil/~bruninga/APRS-SPHEV.html

Although, it is a prius, used in the testing, I think the technology would be very similar. But, my initial problems are that I have not been able to find any wiring schematics for our trucks. Also The website does not have a contact person to ask for more details as to how he seperated the 2 batteries to prevent over-charge of the stock battery while still having the aux batteries supply power on demand and accept regen power.

Any help, advice, or areas to turn to would be greatly appreciated.

Thank you.
