to deliver 200-400 full (80% DOD) cycles. The added weight is around 300 lbs,

  2. Ryan's PriusBlue is the testbed for DC-DC PFC Based PiPrius kits and documentation for DIY projects.
  3. Toyota OEM Prius PHEV and Prime Could use some work on this page
  4. Enginer China. But the rest of these appear to all be defunct as of 2020?

Per eaa-phev maillist 'Conversion instructions' message of 10/18/2006

Request for Show of Interest in Converting Prius to PHEV Instructions

Please respond directly to tdriscoll@calcars.org by copying these questions into your message and adding your answer after each one. Any response is not a commitment to buy anything, or an order, but a way to help us make it easy for you by helping determine how far to go in having components made. We want to know from the converters the following:

1. How definite are you about doing a conversion with our open source plans?
2. What is your timeframe?
3. What fabricated components or assemblies are you interested in buying, at the following estimated prices?

Estimated Fabrication Costs

Assembled and tested circuit board $250-500
Battery tray (4 needed) $150-250
Battery box top $150-200
Battery box foundation $150-200
Electronics tray, assembled and wired $500-1K
Set of pre-built battery cables $150-200
Pre-built low-power wiring harness $150-300
Total (including 4 trays) $1950-2500

These are estimates for the labor only; approximate components costs are at PriusPlus#Parts_availability.

4. Are you interested in becoming a fabricator and/or kit supplier?

This question applies to for-profit businesses (we know of one or two who may be interested) as well as to individuals.

a. Are you interested in fabricating subassemblies? If so, which ones?
b. Are you interested in assembling components into full or partial kits?
c. Would you be interested in organizing the orders? We need a volunteer or for-profit business to organize this process of deciding what the interest is, what can be economically be built given that interest, who will do it; then how to commission, order, pay for, collect, store, and deliver the parts and subassemblies.
