Toronto, ON. February 21, 2006: unveils Plug-in Hybrid Technology at the Canadian International Autoshow in Toronto to use Lithium Ion Polymer battery.

Initially, Canadian company Hymotion is offering the PHEV upgrade in two models: the 5kWh L5 for the Prius and the 12kWh L12 for the Ford hybrid SUVs. This innovation is not cheap, so the company is targeting fleet buyers before individual consumers. In quantities greater than 100, the Prius L5 is US $9,500; quantities over 1,000 drop the price to US $6,500. Other systems are under development for the Lexus RX400h, Toyota Highlander Hybrid and Toyota Camry Hybrid.

This div does not appear withing the page but is used to define the references used below. If multiple ref tags were to appear within the table only the text from the first would be displayed. Thus we pre-define them here, the only side effect being that the first "a" backlink does nothing.

<ref name=ev_range> EV range [mi] or All Electric Range (AER) Assuming <35 mph, 210 Wh/mile (260 Wh/mi from grid) per, 1.5 miles is approximately the range with a fully charged stock battery pack</ref>

<ref name=phev_range> 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.</ref>

<ref name=safety> Safety in case of major accident

  1. Many Lithium cells will burst in flames if penetrated. However, phosphate cathode LiIon cells (such as Valence and A123) are flame-proof.
  2. SLA batteries contain lead and sulphuric acid but are spill-proof</ref>

<ref name=charge_time> 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)</ref>

<ref name=energy> 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:

  1. SLA: 0% down to 50%, due to Wikipedia:Peukert's law much of the nameplate capacity is unavailable.
  2. Lithium: 0% down to 90%, has far less Peukert losses and can be safely deep discharged.</ref>

<ref name=spare_tire> 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.</ref>

<ref name=convert_service> Conversion service: done by the PHEV conversion company, at their location. Conversion kit: done by the owners in their hometown.</ref>

  • Doc: Open Source Documentation in progress.

  • Unknown: Unknown: No public news the last 12 months
  • Prod: Production: Working vehicles on the road, performing conversions or supplying kits.</ref>

<ref name=topology_type> 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.</ref>

Notes: <references/>

So Hymotion can do $6,500 for 1000, $9,500 for 100 or more, and probably similar to the $10K-$12K of EDrive for an order of a single vehicle. They both go nearly the same distance at 31 vs 35miles, Hymotion is rated 5kWh and 40.9kg lighter than the EDrive at 9kWh, 1.8 times the energy at 1.56 times the weight.

While the battery type could make up the specific energy differance of 69Wh/kg versus 89Wh/kg the range discrepency is still odd. This could be due the SOC range used, though one would suspect that most of the capacity would be utilized as that's one of the things Lithium does well. Perhaps EDrive is being conservative on cycle depth, DOD, as I believe there is no stock battery to fall back on for HEV opperation in their case, while Hymotion could effectively discharge the additional Li pack till it fell off the end of it's abrupt discharge curve at 100% DOD, or 0% SOC.

Anyway, some Electric Conversion guys I know have mentioned that they think a simple "Hybrid battery", as it's known in the BEV world, type setup where a larger battery feeds the stock one would work, which Hymotion. seems to have confirmed. The PriusPlus or EDrive method still has the advantage of being able to replacing the stock NiMH battery with a far lighter Lithium flavored one!

Notice the trend towards the magical $500/kWh at 1000 units on the Hymotion battert packs, figure $1500 for the other hardware... This is about the cost of current mass production small form Li cells, who knows what happens to the cost once you ramp vehicle scale production into the millions? $250/kWh? $100/kWh? Keep in mind that something like the tzero with 6800 18650 cells is about 1000 laptops worth, so each PHEV might represent 200 laptops, 1000 cars = 200,000 laptops...
