Notes:
- ^ a b
EV range [mi] or All Electric Range (AER) Assuming <35 mph, 210 Wh/mile (260 Wh/mi from grid) per http://www.greencarcongress.com/2005/08/solarpoweraugme.html, 1.5 miles is approximately the range with a fully charged stock battery pack
- ^ a b
PHEV range [mi] or Blended mode Range (BMR) During which the mileage is on the order of 100 mpg. Shows range as stated by organization.
- ^ a b
Safety in case of major accident
- Many Lithium cells will burst in flames if penetrated. However, phosphate cathode LiIon cells (such as Valence and A123) are flame-proof.
- SLA batteries contain lead and sulphuric acid but are spill-proof
^ a b c d
Charge time [hours] From discharged to the point the pack will no longer be used in PHEV, to fully charged.
- (per Orbital, SLA require 8 hr taper -- done at least once every 3 days -- after near full charge, to reach 100% and prevent sulfation)
^ a b
Available energy [KWh] Because the DOD of the stock pack is limited by the Prius, only about 0.3 KWh of its energy is available (used). It is assumed that additional batteries are limited to a DOD range of:
- SLA: 0% down to 50%, due to Wikipedia:Peukert's law much of the nameplate capacity is unavailable.
- Lithium: 0% down to 90%, has far less Peukert losses and can be safely deep discharged.
^ a b
Spare Tire access
- No the original tire well is covered or occupied by the new battery pack and must be secured and stowed in the rear cargo space.
- Yes the original tire well is accessible.
- Opt Optionally the battery box may be implemented in such a way to preserve access.
^ a b c
Conversion service: done by the PHEV conversion company, at their location.
Conversion kit: done by the owners in their hometown.

Project Status:
- Doc: Open Source Documentation in progress.
- Dev: Development: Working vehicles on the road but some features still under development.
- Unknown: Unknown: No public news the last 12 months
- Prod: Production: Working vehicles on the road, performing conversions or supplying kits.

Topology Type:
- New New Battery Pack and BMS, the OEM NiMH battery and BMS are replaced with a simple string.
- Hyb OEM NiMH battery and additional battery are both utilized in a hybrid battery pack configuration, OEM BMS continues to manage OEM battery.
- Con Contactors are used to parallel the OEM and PHEV batteries.
- DC A DC to DC converter is used to move power forward from the PHEV to the OEM Battery.
- CV The CAN-View is used to manage the PHEV systems operation.
^ CalCars is based in California, however locations where progress is being made and help is available now include CA, CT, CO, IL, and TX.
^ CalCars completed the 1st ever Prius PHEV conversion 11/04, With six by 5/07 (One which became the test bed for the PiPrius project, two of which uses NiMH, and the latest which retains the spare tire.)
^ CalCars Batteries: ~$1K ($3-$5K for NiMH) Charger: $0.9-$2K Total: $3-$4K + labor for PbA conversions and an additional $3 to $5K for NiMH
^ CalCars uses 20 * BB Battery EVP20-12B SLA (Sealed Lead-Acid). Have used Electroenergy NiMH in EEEI Prius and Nilar NiMH in Nilar Prius, evaluating Lithium.
^ PiPrius vehicles include PriusBlue, WhiteBird, and GrayPearl.
^ PiPrius Charges in about 3 hours @ 120v & 15a or can be charged in as little as 0.4 hours (24 minutes) @ 240v & up to 40amps with manual current control from 0 to 40amps.
^ PiPrius Batteries: $0.8K~$1.2K Charger/DC-DC: $3K Target: ~$10K
^ PiPrius notes:
- The PiPrius PFC40H charger doubles at the DC-DC converter between the OEM and added battery packs.
- BMS consists of a Mk 3 Reg on every battery, which fully protected each battery on charge and discharge mode.
- The BMS is programmable with a laptop, with no security locks (open source).
^ PiPrius uses 15 * Hawker EP26 SLA (Sealed Lead-Acid), 24 * 20Ah SLA., Evaluating Lithium, or users choice of chemistry, voltage and capacity.
^ EnergyCS has 9kWh of battery capacity from a 230v 40Ah pack
^ EnergyCS uses Valence Saphion phosphate cathode LiIon cells extracted from U-Charge packs
^ Amberjac uses the EnergyCS system electronics but a different battery manufacturer.
^ Amberjac has 9kWh of battery capacity from a 230v 40Ah pack
^ Amberjac works closely with EnergyCS but uses a different battery system and manufacturer though the same (LiFePO4) chemistry
^ EDrive Through cell separation
^ EDrive uses Laptop Cobalt LiIon 18650 cells
^ In the past, Hymotion has stated 50 km (30 miles) pure EV range. Yet 4.3 KWh calculates out to 15 miles. The specs on their new website say "Up to 100 mpg for 30-40 miles", which means blended mode, and is indeed consistent with the energy stored in the battery
^ Hymotion $10K may or may not include installation, depending on source
^ Hymotion uses Lithium polymer (future: A123 LiIon)
^ Plug-In Conversions High capacity chargers extra
^ Plug-In Conversions Uses Gold Peak NiMH 10GP30EVH
