Rich Rudman of manzanitamicro, Ryan, and PriusBlue, are working on a Prius PHEV implementation using an upgraded PFC-30 as a DC-DC converter and charger, and Rich is hoping to develop and offer conversion kits.

Misc development related stuff:


Logs

CAN-View Logs from Initial PHEV Test & Tune runs:

Cap0040-41, 11 miles >99.9mpg
Cap0060, 28 miles 78.5mpg

Current CAN-View Relay settings:

RL2: on <69 off >70%SOC & on >70 off <70Acl
RL3: unused
RL4: OEM/PHEV selected & >40Acl & Bat <105degF
RL5: unused
RL6: on <74 off >74%SOC & on >50 off <45mph
RL2 (Low) and RL6 (High) speed SOC driven relays are connected in parallel to trigger the PFC to enter NiMH High Voltage setpoint (239V), otherwise PFC is in NiMH Low Voltage setpoint (227v).

Added LowBatReg, a single MarkIII regulator which communicates with PFC to lower current levels in order to keep known lowest PbA battery above 10.0v. Eventually all batteries will have such regulators protecting each from over and under voltage events. Regs will also enhance the ability to equalize the pack and charge safely without manual monitoring.

Restored OEM cooling system to original state, finished testing degraded OEM cooling.


Each .zip file contains a main description .txt file similar to the comments which describe it. There are also multiple CAN-View Capture "raw" .txt files and their resultant .csv files. Each capture file is described with dash miles-mpg|CAN-View Trip screen miles-mpg|CAN-View Ah Count down from 10Ah, a description of the trip, and the amount of recharge.

Conversion Procedures

There are a number of tasks to be completed in order for the entire system to function properly. Those tasks are covered in the following subsections of the Conversion Procedures. These instructions are currently under development and may not yet be complete.

CAN-View & EV Mode Button

Installing the CAN-View and Prius EV Mode Button both involve disassembling the same areas of the Prius so will be covered here at the same time.

  1. Disassemble the dashboard.
    1. Remove the bottom cover of steering column
      1. Releasing the steering wheel adjustment handle and removing the silver screw.
      2. Turn steering wheel 90 degrees to right and left to remove black screws on each side.
      3. Remove the lower cover by carefully pulling down on lower half.
    2. Disconnect the headlamp flasher plug on left side of steering column.
      1. Remove plugs cover by unlocking two side tabs/clips.
      2. Remove 3 unused connector pins using a jeweler's screwdriver to disengage and slide them out.
      3. Optionally to use the headlamp flasher circuit as an EV Mode button:
        1. Solder some length?? of black wire to a new pin and use it to replace:
        2. The ?????? wire to preserve day time flashing function, will disable night time flashing. Preferred
        3. The purple wire to preserve night time flashing function, will disable day time flashing.
        4. Route new black wire over or under steering column towards passenger side of dash.
      4. Snap the cover back onto the flasher plug and reinsert into switch.
      5. Reassemble steering column, be sure everything is aligned properly.
    3. Remove lower glove box by squeezing the inside sides together to lower box below catches, then unclip the small hydraulic piston from right side. Lower box until the lower joints detach from dash.
    4. Remove passenger side silver air vent cover by pulling out from the bottom first. Next remove the small interior colored piece just below the vent piece by pulling straight out.
    5. If installing CAN-View Without Navigation:
      1. Remove drivers side air vent cover.
      2. Remove lower center console hump with 12v lighter power socket.
      3. Remove air vent at right side of MFD screen.
      4. Remove lower drivers side dash panel.
      5. Remove lower dash key fob panel.
      6. Remove drivers side dash.
      7. Remove upper drivers side dash panel with power button.
      8. Remove air vent at left side of MFD screen with shift lever.
      9. Remove 10mm bolts, one on each side of MFD screen.
      10. Attach CAN-View video cable to MFD, run cable out directly behind screen.
      11. Tap grey OEM wire for 12v power, top row 2nd from the left.
      12. Test, then reassemble center and drivers side of dash.
    6. If installing CAN-View With Navigation:
      1. Route OBDII Cable down drivers side of car.
      2. Connect CAN-View video cables to navigation unit.
      3. Tap grey OEM wire for 12v power.
      4. Test and attach above and to rear of navigation unit.
    7. Solder new pin to some length?? of black wire, and optionally the black wire which connects to the headlamp flasher.
    8. Install pin with black wire(s) to ev-mode button location in HV ECU H14#27.
      1. The HV ECU is the one closest the exterior of the car with grey plugs.
      2. H14 is the lowest of the four connectors.
      3. Pin #27 is located on the most interior (broken into three segments) row, the second from the bottom left corner, in the only open location between two red wires.
      4. Using a jeweler's screwdriver raise the white terminal retainer, fully insert the new pin, and re-compress the retainer.
    9. Route CAN-View OBDII cable to OBDII port located above drivers right knee.
    10. Route all wires (CAN, Video, black EV Mode) under passenger side door trim exiting under hole in carpet below passenger seat.
    11. Also route relay cable from below passenger seat under rear passenger side door trim towards rear of car.
    12. Reassemble passenger side of dash and door trim.
  2. Connect all wires to CAN-View
  3. Configure CAN-View, should be preconfigured.
    1. RL1 = EV-Mode Button trigger
    2. RL2 = ? Voltage dither ?
    3. RL3 = ? Regen mode ?
    4. RL4 = Stock / PHEV mode selection
    5. RL5 =
    6. RL6 =

Even if it appears to function properly your actions may cause it to self destruct with collateral damage to surrounding properties other than your vehicle. By utilizing these ideas and instructions in an attempting to enhance national security, reduce gas consumption, vehicle "emissions", your carbon footprint, or smog, you do so at your own risk & peril.

Warranty: In performing some of these modifications you may void your warranty with the vehicles manufacturer.
