Stop-Starting of Autos. ( Solar Thermal Magazine )- Maxwell Technologies, Inc, announced this month that it has been awarded a $2.68 million cost-shared technology development contract by the United States Advanced Battery Consortium LLC (USABC) to develop a high-performance hybrid ultracapacitor/lithium-ion battery for stop-start idle-elimination microhybrid autos.
Maxwell, which will provide 51 percent of the program funding, is tasked with demonstrating the technological and economic feasibility of a 12-volt hybrid energy storage system consisting of lithium-ion batteries and Maxwell ultracapacitors that can meet stop-start auto performance specifications established by USABC. Of particular interest are ultracapacitors’ high power density, long operational lifetime, low-temperature performance and influence on battery performance and lifetime.
Unlike batteries, which produce and store energy by means of a chemical reaction, ultracapacitors store energy in an electric field. This electrostatic energy storage mechanism enables ultracapacitors to charge and discharge in as little as fractions of a second, perform normally over a broad temperature range (-40°C to +65°C), operate reliably through one million or more charge/discharge cycles and resist shock and vibration.
“High-performance, low-cost energy storage systems will be instrumental in meeting growing worldwide demand for more fuel-efficient, lower-emission vehicles,” said Dr. Franz Fink, Maxwell’s president and chief executive officer.
The hybrid battery this program aims to create could be instrumental in strengthening U.S. automakers’ competitive position within a global auto industry that annually produces more than 60 million cars.
