(Earlier post.) The agreement is expected to expedite the development of the batteries for both electric plug-in vehicles and fuel

4、cell variants of the E-Flex architecture. A123Systems currently manufactures more than ten million cells annually, making it the worlds largest producer of batteries with nanophosphate chemistry. Most of these cells are used in rechargeable power tools. In May, 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. The 32-series lineup initially consists of two cells

5、with custom nanophosphate electrode designs, based on the same proven chemistry as the mass-produced ANR26650M1 cell: the 32113 M1Ultra and 32157 M1HD.,Breakthrough battery technology will drive future automotive propulsion, and the company that aligns with the best strategic partners will win. Thats what is so important about this deal. Whether youre talking about the Chevy Volt, a fuel cell or even a plug-in hybrid such as our planned Saturn Vue, we need to understand the fundamental battery c

Bob Lutz, GM vice chairman of Global Product Development,GMs View on Battery Technologies for Hybrids, Plug-Ins and E-Flex,Energy and Power requirements for full hybrids (two-mode), plug-in hybrids, and E-Flex range-extended EVs.,Battery technology and vehicle requirements.,Electrovaya Delivers Plug-in Escape Hybrid to NYSERDA; Application of New MN-Series Li-Ion Cells,Electrovayas subsidiary Electrovaya Company, located in Ballston Spa, New York, has delivered a converted Ford

7、Escape SUV Plug-in Hybrid Electric Vehicle (PHEV) to the New York State Energy Research and Development Authority (NYSERDA). Electrovaya is using its new MN Series Lithium Ion SuperPolymer cellsa lithiated manganese oxide-based systemto build a 12 kWh pack that augments the original NiMH pack in the Escape. Electrovayas testing indicates 130 mpg equivalency from the converted PHEV. The MN cells offer up to 50% higher energy density with comparable safety characteristics to Electrovayas Phosphate

8、 Series, according to Gitanjali DasGupta, Electrovayas Project Manager, Electric Vehicle Program. The MN-Series has an energy density of up to 210 Wh/kg versus the Phosphate wSeries, which offers up to 140 Wh/kg. On a cell-level, the MN-Series offers a volumetric energy density of up to 425 Wh/L. On a system-level, the prismatic large-format construction enables a volumetric saving of up to 22% as compared to cylindrically constructed cellsa volumetric saving common to prismatic cells. The batte

9、ry pack will recharge from 0% to 80% in less than 2 hours at 220V; a complete recharge (0% to 100%) is approximately 4 hours. A full charge at 120V is overnight. This is the first Ford Escape to be converted to a PHEV by Electrovaya and to be operated and tested by NYSERDA as part of the $10-million New York State Plug-in Hybrid Electric Vehicle (PHEV) Technology Initiative aimed at converting the States 500-plus standard hybrids to plug-in capability.,Lithium Technology Corporation Showcases Ne

10、w Battery Pack for Plug-in Retrofit,The LTC PHEV pack for the Prius. Click to enlarge.,The LTC Prius PHEV,Lithium Technology Corporation (LTC) has retrofit a Toyota Prius to a plug-in hybrid using a battery pack based on LTCs new product line of large-format lithium iron phosphate (LiFePO4) cells, the largest cells of their kind in the world. The 7 kWh battery pack, comprising 63 of LTCs 3.2V, 35Ah iron phosphate cells, could support fuel economy of up to 125 miles per gallon, the company extrapolated, based on the performance of a smaller 2.2 kWh li-ion pack used in the Zytek smart for four conversion in the UK. LTC cells use LiFePO4 licensed technology, developed by Prof. John Goodenough with the University of Texas and supplied by Phostech.,
