|Click show for a short list of the current PHEV conversion and kit options for the Toyota Prius.|
This item is out of date but kept for posterity sake,
This is where you will find schematics, PCB layout, and parts lists for various Prius PHEV conversions.

Original CalCars Method
Per EAA-PHEV_Maillist:2006./3./40 we hope to have up to date PCB and Parts Lists by early April.
- SOC & Control Schematic
- The control schematics contains various runlevel interlocks and manages the other parts of the conversion.
- Battery Tap Emulator Schematic
- High Power Schematic
- The High Voltage Schematic deals with all the high voltage connections, relays, fuses, and the battery pack itself.
Changes from V1 to V2
As part of a Prius conversion to be done over the course of the Inaugural Maker Faire, April 22-23, we will be dramatically improving the documentation of the basic PbA PRIUS+ conversion process. We will also be publishing complete parts and supplier lists and designing prited circuit boards for the electronics, which we will find some way to get produced for sale afterwards. If you live close enough to get there, please join us to observe a real conversion in process.
Version 2f HV board schematic and Jerry's parts list additions. Ron added D11-12 to solve a bug I just fixed on his car. While he was at it, he changed D2 from a 1N4002 to a 1N4003 so that only 1N4003 of that series diodes is used. Ron found Q3 missing from the parts list, so It was added. We will have to solder D11 and D12 to their associated transistors when stuffing the boards, as the HV board is already in fab based on versions 2e -- our first rework.
Version 2c schematics are now available, some of the changes since Version 1 are:
- Add the ability to switch back to the OEM battery pack at will (important for PbA battery packs, which are unreliable at low temperatures. Also handy during the testing process and perhaps to preseve a full charge for demonstration at a destination)
- Improve compatability with CAN-View, which will now be the first and recommended Prius PHEV User Interfaces or BMS spoofing and EV-mode automation system (Ron is actively working with Norm, CAN-View's creator, to ensure effective automation algorithms)
- Move all high voltage circuitry off the low power control board to the HV battery tap emulator board.
The control schematics contains various runlevel interlocks and manages the other parts of the conversion. Template:PriusPlus Control Parts
Battery Tap Emulator Schematic
The Battery Tap Emulator board also contains the State Of Charge Manipulation circuit and a set of relays which allows for the stock battery pack and it's native taps to be used if nessecary. Template:PriusPlus Battery Tap Emulator Parts
