Prius PHEV
There have already been a number of successfull Prius PHEV conversions such as Ron of CalCars PriusPlus and a similar EDrive consumer conversion, which is expected to become available in 2006. The tenth conversion was undertaken in public at the Inaugural Maker Faire to help enhance the documentation and help promote PHEVs in the pacific northwest and midwest. A company called Hymotion will be offering conversion kits to fleets and eventually consumers. Recently CalCars has begun working to perfect various #Hybrid-Pack Method techniques to remedy the CCL Conundrum.
See the Terms page is you aren't familure with some of the acronyms used throught the documentation. Also be aware of the Disclaimer should you be considering a conversion yourself. This PriusDisMan.pdf copy might be handy for its dismantle and safety warnings
At this time there are two common conversion methods for the Prius. The #CalCars Method used in Rons PriusPlus and EDrives conversions replace the stock battery with a new simple string. The second #Hybrid-Pack Method which is believed to be used by the Hymotion kits for the Prius and Escape use a hybrid battery pack configuration which uses both a new simple string and the original stock batteries. Other upcoming conversion projects for Classic 2000-2003 Prii and Ford Escape might also use this method. Both types of course use a Battery Chargers to refuel from the grid. Toyota has stated that such a conversions will affect your Warranty.
Original CalCars Method
Further development of the Original CalCars method has been postponed to persue the #Hybrid-Pack Method:
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 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 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:
As of yet un-implemented except perhaps by Hymotion, till we know more see Battery Pack Configurations#Hybrid for the core ideas surrounding this method or Prius PHEV Battery Pack for more specific battery information. CalCars is now working towards implamenting 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 and has provided these documents from 2004 which have information and considerations regarding these configurations.

PFC Based
Ryan is working with Rich Rudman of manzanitamicro on an implamentation using an upgraded PFC-30 as a DC-DC converter and charger, and Rich is hoping to develop and offer conversion kits.
Electro Energy has successfully demonstrated a PFC based setup with NiMH durring CalCars trip to DC.
