Revision as of 08:52, 9 October 2007

This is where you will find schematics, PCB layout, and parts lists for various Prius PHEV conversions.

Original CalCars Method

Further development of the PriusPlus History or Prius PHEV#Original CalCars Method has been postponed to persue the Prius PHEV#Hybrid-Pack Method so the original schematics can be found at Prius PHEV Schematics-CalCars

Hybrid-Pack Method

There is no longer a need for the Battery Tap Emulator.

The HV interface with the original battery is made after the HAL sensor.

       - Key On Interlock opens a NC relay which grounds the (+)pos OEM Contactor.
       - Run Interlock opens a NC relay which would otherwise go (+12) upon Key On.

Enhanced Regen

Regen may need to transfer power through the OEM HAL sensor in order to:

  • Avoid Negative State Of Charge Drift which may not work like +Drift.
  • Allow current to be counted instantaneously and thus recover from or avoid CCL.
  • Allow for the use of the Prius as a DC Genset if PFC sources NiMH pack.

Potential Enhanced Regen methods

  • Use the PFC as is, switch Input/Output and change voltage setpoint.
    • Modify the PFC so it can move 2x amps in DC modes only.
    • Use a PFC power stage.. so we can stuff 150 amps in any direction.
  • Use a Honking Big diode and a properly sized PbA Pack.
  • Use a contactor and a diode and a properly sized PbA Pack.


Automatic Charge - PHEV Drive Mode Change (No Regen)

 Automatic [ Charge - PHEV Drive ] Mode Change, HV & LV Layout
 coil 01 is a pair of DPDT or a single 4PDT
 coil 02 is a SPST (Rated 40+ Amps for DC MAKE/BREAK)
   * Ignition energizes mode change (unless PFC is running from grid)
   * CAN-View RL4 (OEM/PHEV Mode) energizes Coil 02 powering up PFC (DC MAKE)
   * Once PFC is running mode change is energized by both ignition and PFC RegBus
   ** Ignition off results in CAN-View RL4 releasing powering down PFC (DC BREAK)
   ** Mode change can only return to grid once PFC RegBus goes offline
