Hybrid Battery Collaboration Announced

Maxwell Technologies and Argonne National Lab to collaborate in lithium ion/ultracapacitor research

Maxwell Technologies, Inc. announced today that it will supply ultracapacitor cells and integration kits to the U.S. Department of Energy's Argonne National Laboratory for a collaborative research project for hybrid-electric and plug-in hybrid vehicles.

Argonne will provide batteries and power electronics, design and fabricate the integrated energy system for installation in the Hardware-in-the-Loop (HIL) of the Advanced Powertrain Research Facility (APRF) in Argonne's Center for Transportation Research.

The research will center around ultracapacitors' rapid charge/discharge capabilities and their ability to handle the heavy cycling involved in regenerative braking, torque assist and other demands on energy storage systems for hybrid-electric and plug-in hybrid vehicles.

Argonne and Maxwell have agreed on an active parallel system configuration that will combine a standard lithium-ion plug-in hybrid battery with a string of 112 of Maxwell's BOOSTCAP(R) BCAP0650 P270 650-farad ultracapacitor cells, along with appropriate power electronics and cooling and safety-related features. The system will undergo HIL validation during the summer of 2007.
