Revision as of 05:24, 22 June 2006

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 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.

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.
