Welcome to the new home of the EAA-PHEV Project, which formerly lived at the site.

We're still moving in to the new site so please bear with us, the migration plan can be found on the discussion page. The old EAA-PHEV page will be named Prius HSD PHEV, the EAA-PHEV_PRIUS_Documentation is now named PriusPlus, and the old Conversion Hybrids & PHEV Projects pages are now on the History page. We're also making room for more pages to address the potential conversion for each of the current production hybrids, many of which have similar powertrains to that in the Prius.

Here on the main page we should address some of the basics, such as:

  • What is a Hybrid, versus an all electric vehicle?
  • What's all the fuss about "plugging in", what differance does it make?

CalCars' Plug-In Hybrids page has a good explanation; Ron Gremban's PHEVs: the Technical Side presentation notes follows up with a technical overview of gasoline vs. flex-fuel vs. Diesel vs. hybrid vs. plug-in hybrid vehicles, followed by the (positive) social implications of PHEVs and especially flex-fuel PHEVs.

  • What changes do we make to convert a gas only hybrid to a Plug-In Hybrid?

Basically, one either replaces or adds to the vehicle's hybrid battery for greatly increased energy storage capacity, adds a charger that plugs into a wall outlet, and arranges for the hybrid system to use more (or only) electricity and less (or no) gasoline for propulsion until the battery is mostly depeleted. This last bit is the tricky part, as the control systems of all the hybrid vehicles are proprietary and secret.

  • What does the number after the PHEV represent, how do we measure their mileage and performance?

This number represents the electric propulsion range of the PHEV before it must depend upon its internal combustion engine for motive power. In English-system (vs. metric) countries like the U.S, it is in miles. A PHEV-20, for example, has a 20-mile electric-only range. Due to its limitations, the PRIUS+ is more complex to describe, as, in mixed city and highway driving it is only 50:50 electric/gasoline. CalCars' original PRIUS+, though actually a PHEV-10, generally travels 20 miles at double its hybrid gasoline mileage (rather than 10 miles powered purely electrically) before its battery is depleted.

  • What types of hybrids are there? Full, Mild, Series, Parallel, Series-Parallel
  • etc...

Pluginpartnerslogo.gif is a national grass-roots initiative to demonstrate to automakers that a market for flexible fuel PHEVs exists today. "Forget Hydrogen, Forget Hydrogen, Forget Hydrogen". "It's a coalition between the Tree-Huggers, Do-Gooders, Sod-Busters, Cheap Hawks, and the Evangelicals". --James Woolsey, former director of the CIA. Sign the petition, watch the webcast, and spread the word. In short, a PHEV delivers all of the advantaged of a BEV while retaining the unlimited range of traditional gas vehicles.

Calcars-logo-large.png is a nonprofit startup that blends advocacy with technology: advocacy to compel automakers to produce plug-in hybrid vehicles and consumers/fleet buyers to understand their myriad benefits; technology to prove what's possible -- today. CalCars created the first PRIUS+ conversion in 2004 and has been working to achieve media traction and widespread awareness ever since.
