When Saab unveiled its first-ever electric vehicle (EV), the 9-3 ePower, we ecstatically claimed:
Unfortunately, we had to close that article with the words of Saab chief executive officer, Jan Ake Jonsson, who was prodded about a target release date for Saab's first EV and responded with:With a projected range of 125 miles and a 0-60 mile per hour acceleration time of less than 8.5 seconds, Saab's first-ever electric vehicle, the 9-3 ePower, brings the automaker into the battery-powered mix with authority. Based on the 9-3 Sport Combi wagon, the Saab 9-3 ePower's cargo-hauling abilities offer versatility that's typically absent in the battery-powered segment.
Now, some new info suggests that the ePower could be production-ready sooner than first thought. That is, provided that Saab gives it the green light. Boston-Power, supplier of the ePower's battery pack, revealed that its Swing 4400 cells provides the punch for Saab's EV. The Swing cells are not Saab-specific and are already available at a mass-production level.Everybody is looking at that question. Nobody has an answer. It will take some time.
The Swing cell utilizes cobalt and manganese on the cathode with graphite on the anode and is based on an oval-shaped prismatic cell design. The external dimensions are nearly equivalent to two 18650 lithium-ion cells, but testing has proven that the Swing 4400 cells are quite robust and Boston-Power claims that the cell specs 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)
