Maxwell Technologies to Develop High-Performance Hybrid Ultracapacitor/Lithium-ion Battery for Stop-Start Autos
Maxwell Technologies (Nasdaq: MXWL) 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.
USABC is a subsidiary of the United States Council for Automotive Research LLC (USCAR), the collaborative automotive technology organization for Chrysler Group LLC, Ford Motor Company and General Motors. With funding provided by the U.S. Department of Energy, USABC’s mission is to develop electrochemical energy storage technologies that support commercialization of electric, hybrid-electric and fuel cell vehicles.
Total production of EVs—both pure electric models and plug-in hybrid electric vehicles (PHEVs)— is projected to rise to more than 403,000 this year, up from slightly more than 242,000 in 2013. Growth will accelerate sharply from the 44 percent increase in 2013, based on data from the new IHS Automotive Hybrid-EV Portal.
The huge increase in the EV market this year contrasts with the 3.6 percent rise in global manufacturing of all motor vehicles expected in 2014.
China BAK Battery, Inc. has entered into a new contract to supply high-power batteries to Chery Automobile Co., Ltd. China BAK will deliver 1,000 high-power lithium-ion battery units in 2012 to power Chery’s Ruilin M1 electric cars. The new contract is in addition to China BAK’s contract to supply 100 high-power battery units to Chery, which are on schedule to be delivered by June 2012. The Ruilin M1 is one of the five electric vehicle models that have been approved for government use since early this year. Chery and China BAK also plan to announce a long-term cooperation program in the electric vehicles industry.
ALTe Powertrain Technologies, the Michigan developer of a Range Extended Electric Powertrain, has signed a Letter of Intent (LOI) to form a joint venture with Inmatech, Inc., a developer of advanced supercapacitors, to produce and sell hybrid electric storage (HES) devices composed of batteries, supercapacitors and control electronics.
The blend of supercapacitors with lithium ion battery cells will enable longer life for the battery cells while reducing cost by as much as 40% for an equivalent size battery composed exclusively of lithium ion cells. The applications will range from automotive batteries to stationary grid power leveling devices.
AeroVironment, Inc. (AV) said lithium-ion battery maker EnerDel, a subsidiary of Ener1, Inc. will purchase eight AV electric vehicle power cycling and test systems.
The addition of AV’s 170 kilowatt ABC-170CE cyclers and its 250 kilowatt AV-900 heavy-duty cyclers will expand the advanced battery testing capabilities at EnerDel’s Indiana facility. Both test systems are programmed to simulate real world driving conditions by repeatedly charging and discharging EnerDel’s hybrid and electric vehicle batteries to replicate actual operating conditions.

The hybrid battery in the Mercedes-Benz S-Class S 400 HYBRID weighs 25 kilograms. It consists of 35 cylindrical, rechargeable lithium-ion batteries and delivers a peak power of up to 15 kW (20 HP). Electric and thermal protection of the battery are among the battery ECU’s most important tasks. The ECU’s algorithms were developed in a joint venture between Johnson Controls and SAFT. dSPACE TargetLink was used to generate the ECU software.

July 28, 2009 – UQM Technologies (www.uqm.com) said it will supply UQM®PowerPhase® 100 electric propulsion systems to Coda Automotive (www.codaautomotive.com) for a period of ten years. Coda is a California-based electric car and battery company that separately announced the close of a Series B investment round totaling $24 million.
The UQM system delivers 100 kilowatts (134 horsepower) of peak power, 300 newton meters (221 pound feet) of peak torque and a peak system efficiency of 94% in a 280 millimeter (11 inch) diameter by 252 millimeter (10 inch) long package.
July 27, 2009 – An electric drivetrain developed by Think (www.think.no/) and powered by a lithium-ion battery system made by Ener1 (www.ener1.com) subsidiary EnerDel (www.enerdel.com) has been delivered to the Japan Postal Service (www.post.japanpost.jp) via conversion partner Zero Sports (www.zerosports.co.jp).
The drivetrain is being used to convert a gasoline-powered truck to run entirely on electric drive. The Japan Postal Service is converting 25% of its fleet of combustion engine vehicles to electric drive as part of a government push to accelerate market adoption and infrastructure development for electric drive vehicles. The postal service selected Zero Sports of Japan as a conversion partner for delivering vehicles as part of a program to electrify Japan Post’s fleet of 22,000 delivery vehicles.
