The California Cars Initiative (CalCars.org) will publicly convert a Toyota Prius hybrid into a plug-in hybrid during the inaugural Make magazine Maker Faire, April 22-23.
Over two days, CalCars engineers, along with a cadre of volunteers, will build and install a battery pack and make hardware and software adjustments to the stock Toyota Prius. The finished PRIUS+ will drive back to Seattle, Washington after the Faire with a 10-mile low-speed all-electric range in addition to its regular hybrid extended range.
The Maker Faire is to be held at the San Mateo Fairgrounds in San Mateo, California. Information is available at Make magazine.
The project is a dry run for the EAA-PHEV effort that is developing Open Source (non-proprietary) electronic designs, instructions and recommended components so experienced engineers can complete “do-it-yourself” (DIY) conversions on their own.
Along with the two private companies now about to offer after-market installed retrofits (Hymotion and EDrive), this will put some additional plug-in hybrids on the road
