Plu-in Prius'

 

Plu-in Prius'

We have a handful of regular Prius'. We have heard of conversions to make them plug-ins. Prices and types on the internet are all over the place from $2000 to $20000.

I heard in Williamsburg that some of you had converted Prius' into plug ins.

Please provide me with any info you have that would help us pick the right direction.

Just FYI... The City of Anaheim converted two Prius's to the Hymotion A123 system for @ $12,500 each. We are seeing @ 60 to 80 mpg (depending on driver) from the plug in conversions...

Has any amortization analysis been done on this conversion?  I realize it is often appropriate to pay some "premium" for contributing to improving air quality and am interested in what those "premiums" might be.  Thanks

We got four A123 Hymotion conversions done last year @ $10,395 each. There is a total of 17 PHEV Prius' in service here.  For mileage- your results will vary. In actual use for short trips and without driver training you may actually see decreased MPG. As Karl said, we've seen up to 80 MPG under ideal driving conditions. As far as amortization, I suggest pursuing grant funds for the conversions. You will not see a full return on the initial investment during the life of an aftermarket PHEV conversion.

At current fuel prices ($2.64) the aftermarket A123 plug in system will NEVER pay for itself in a normal lifecycle scenario. At an approximate $0.03 per mile savings in fuel over the standard Prius we would have to run the plug in Prius @ 375,000 miles before breaking even on the $12,500 cost of the conversion. Even at $5.00 per gallon, the ROI is @ 200,000 miles. So much depends on the driver. I have had some get @ 90mpg and others get under 50 mpg in the same car. I am using the average of 70 mpg for ROI calculations.

I haven't done any emissions calculations to find out the cost for emissions reductions, but since the standard Prius is so clean burnng, the plug in would probably only offer modest gains in emissions reductions.

Using plug in hybrids was a City Council directive, so the cost for the plug in conversion is just part of the political cost of doing business. That is why I am hoping the factory Toyota plug in has a much lower added cost over the standard model than the aftermarket kits so there may be a reasonable return on investment.

Thanks very much.  That is good information, and not surprising.
