Saab EV Prototype Using Boston Power Swing Cells Already in Mass Production

The recently announced Saab 9-3 ePower battery-electric vehicle (earlier post) is using Boston Power’s Swing cells (earlier post) already in mass production, according to Boston-Power Founder and CEO Dr. Christina Lampe-Onnerud.

Boston-Power collaborated to deploy a Saab ePower-specific implementation based on the handshake between the drivetrain and the battery, Lampe-Onnerud said.

Boston-Power uses cobalt and manganese on the cathode with graphite on the anode. Its battery technology platform is based on a flat, oval-shaped prismatic cell design with external dimensions equivalent to two conventional 18650 lithium-ion cells. Each cell incorporates multiple, independent safety devices located in different areas of the cell.

Swing cells are targeted for electric vehicle, industrial and electronic applications. Some of the attributes of the Swing 4400 include:

  • Energy density of 180Wh/kg
  • Volumetric density of 420Wh/L
  • 1,000+ cycles at 100% Depth Of Discharge (DOD)
  • 2,000+ cycles at 90% DOD
  • Constant power of 440W/kg
  • Pulse power of 1,500 W/kg (2s pulse)

A rugged battery pack with performance on par with (or better than) current equivalent units. Th 1000+ cycles @ 100% deep DOD is exceptional and demonstrates what can be done.

Yet another battery maker that is building strategic alliances with a major brand EV. With so many players in the market we can expect to see significant cost/size reductions along side energy density increases.

It's probable with these specs that other bigger car makers are considering the Boston-Power products.

Those are very good specifications. This is about as close as we will get to the fabled "free market competition". Some companies are funded better than others, but may the best battery win should be the rallying cry.
