Boston Power’s Battery System For Zero Emission Saabs

Posted on 11. Dec, 2009 by in 2000-2009

Here is the information on Boston Power’s “Swing” Battery system for use in the 100 Zero Emission Saab 9-3s.

It looks very promising and I can’t wait for a day where I could test drive a zero emission Saab. With this program already in play and now with financing, it seems like it’s just a matter of time, and not much either.

Boston-Power’s Swing Battery – Electric Vehicle and Transportation Applications

Based on our lithium-ion battery technology platform and designed to meet the requirements of a wide range of transportation systems, the Swing 4400 is one of the most cost effective solutions available today. Swing’s extended cycle and calendar life and high energy density make it 20-50% more efficient in system weight and space compared to existing solutions. The Swing 4400 also provides the high constant and transient power required in many electric vehicle applications.

Some of the key benefits offered by the Swing 4400 over alternative cell technologies include:

* High energy density of 180Wh/kg
* Volumetric density of 420Wh/L
* Industry-leading cycle life:
o Over 1000 cycles at 100% Depth Of Discharge (DOD)
o Over 2000 cycles at 90% DOD
* High constant power of 440W/kg
* Pulse power of 1500 W/kg (2s pulse)
* Flexible and scalable packaging
* Excellent thermal properties
* Nordic Ecolabel accreditation
* UL, UN, and ROHS certifications

    I love our Saabs (a 2003 9-3 and a 2001 9-5). We’d buy a ZE 9-3 tomorrow if we could. Why only 100? When will they be in production?
