A123Systems introduced its automotive-class, large-format 32-series Li-Ion cells specifically designed for Hybrid Electric Vehicle (HEV) and Plug-in Hybrid Electric Vehicle (PHEV) use at the Advanced Automotive Battery Conference 2007 in Long Beach, California.
The 32-series lineup initially will consist of two cells with custom Nanophosphate electrode designs, based on the same proven chemistry as the mass-produced ANR26650M1 cell: the 32113 M1Ultra and 32157 M1HD.
A123Systems anticipates that the 32113 M1Ultra high power cells will offer industry-leading power by volume and cost-per-watt. Designed to meet the requirements of HEV applications, the 32113 is currently designed into A123Systems’ programs with major US and European auto manufacturers.
The 32157 M1HD cell uses a higher-energy electrode design geared specifically for PHEVs, and should offer greater volumetric energy density and the lowest cost per watt-hour. Currently used in a Saturn Vue PHEV development program, the 32157 is designed to offer superior calendar and cycle life at high depth-of-discharge (DOD), as well as excellent power density for charge-sustaining operation.
Actual performance data is not yet available.
A123Systems says that it optimized the automotive-class lithium-ion cells to offer power, safety and life at price-performance targets that can enable the wider adoption of lithium-ion technology in the auto industry. Wide power availability over a broad range of state-of-charge as well as exceptional endurance implies that systems with both cells will require minimal oversizing, allowing for lower overall systems cost.
The 32-series cells are designed with abuse-tolerance in mind and will deliver 10+ year and 150,000 mile projected life requirements in engineered automotive battery packs.
A123Systems developed its Nanophosphate chemistry with the assistance of the Department of Energy FreedomCAR program and is a result of more than $102 million in private investment.
