To this date there have been a number of successful [[Toyota Prius|Prius]] [[PHEV]]<ref>[[Maillist]] & http://groups.yahoo.com/group/gridable-hybrids</ref> conversions beginning with [[User:Rgremban|Ron]] of [[:Category:CalCars|CalCars]]<ref>http://www.CalCars.org & http://groups.yahoo.com/group/calcars-news</ref> [[PriusPlus History|Original]]<ref>http://groups.yahoo.com/group/priusplus</ref> and current [[PriusPlus]].
Other small startups include the [[PiPrius]]<ref>http://www.PiPrius.com & http://www.manzanitamicro.com</ref> ''(WA)'' and [[Hybrids-Plus]]<ref>http://hybrids-plus.com & http://energysense.com</ref> ''(CO)'' projects.
[[EDrive|EDrive/EnergyCS]]<ref>http://www.edrivesystems.com</ref> ''(CA)'' will offer consumer conversion soon, and has produced the most evaluation Prius PHEVs to this point.
Canadian [[Hymotion]]<ref>http://www.hymotion.com</ref> ''(Toronto, ON)'' is offering conversion kits to fleets and eventually consumers.
The tenth conversion of [[PriusBlue]] was undertaken in public at the [[Inaugural Maker Faire]] to help enhance the documentation and help promote PHEVs in the pacific northwest and midwest.
Recently CalCars has begun working to perfect various '''[[#Hybrid-Pack Method]]''' techniques to remedy the [[State Of Charge Manipulation#Charge Limit Conundrum|CCL Conundrum]].

At this time there are two common conversion methods for the Prius.
The '''[[#Original CalCars Method]]''' used in Rons [[PriusPlus History]], [[EDrive]], and [[Hybrids-Plus]] conversions replace the stock battery with a new [[Battery Pack Configurations#Simple|simple string]].
The second '''[[#Hybrid-Pack Method]]''' is used in the new [[PriusPlus]], [[PiPrius]], and believed to be used by the [[Hymotion]] conversions.
This second method should be easily adapted from the '04+ [[Toyota Prius|Prius]] to the ''Classic'' '00-'03 Prius, [[Ford Escape Hybrid|Escape]], and other [[Hybrid]]s as they use a [[Battery_Pack_Configurations#Hybrid|hybrid battery pack configuration]] which uses both a new simple string and the original stock batteries.
Both types, of course, use a [[Battery Chargers]] to recharge from the grid.
Toyota has stated that such a conversions will adversely affect your [[Warranty]].

The [[Prius PHEV TechInfo]] page has a lot of technical information on the Prius which may be useful when designing a PHEV conversion.
See the [[Template:Terms|Terms]] page is you aren't familiar with some of the acronyms used through the documentation.
Also be aware of the [[Template:Disclaimer|Disclaimer]] should you be considering a conversion yourself.

==Original CalCars Method==
Further development of the Original CalCars method has been postponed to check-out the [[#Hybrid-Pack Method]]:

| valign=top |
This method exploits the [[State Of Charge Drift]] portion of the vehicles battery management routines in order to accomplish [[State Of Charge Manipulation]] with the use of a [[Battery Tap Emulator]]. The result is the ability to effectively change the target [[SOC]] from the normal 3/4 to 1/4 which is more useful for [[PHEV]] applications. The [[Prius EV Mode]] is also utilized to further enhance the use of the additional electric energy provided by a larger [[Prius PHEV Battery Options-CalCars]]. A [[CAN]] device is required to acts as a [[Prius PHEV User Interfaces|Prius PHEV User Interface]] and management device. Such hardware/software will need to follow logic similar to that laid out by [[Prius PHEV Pseudo Code]]. Ron's first [[PriusPlus]] conversion used early proprietary [[EDrive]] technology. Later conversions will use [http://www.hybridinterfaces.ca hybridinterfaces] [[CAN-View]] Scantool which is currently available only for 2004 and 2005 Prius. You can take a looks at [[Prius PHEV Photos]] which are available to help visualize parts of the conversion process.

==Hybrid-Pack Method==
The Hybrid-Pack method:

<strike>As of yet unimplemented except</strike> perhaps by [[Hymotion]], until we know more, see [[Battery Pack Configurations#Hybrid]] for the core ideas surrounding this method or [[Prius PHEV Battery Options]] for more specific battery information. CalCars is now working towards implementing this type of configuration in three Prii with much success thus far. Stay tuned...

===Contactor Based===
Ron is refining a contactor and resistor based setup in his car.
