As it becomes clearer that the economy of the future is not so much a post-industrial economy as a high-tech manufacturing economy, US manufacturers have added about 500,000 jobs over the past three years. In order to “build on this momentum with a comprehensive agenda to invest in American manufacturing,” the Obama Administration has announced… Read more »
PARC, a Xerox company, has launched a project with the DOE’s Advanced Research Projects Agency-Energy (ARPA-E) to demonstrate a new Li-ion battery manufacturing process that could dramatically reduce battery costs and improve performance. The conventional manufacturing process requires that the two halves of a battery be made in two separate steps, and then combined in… Read more »
The prototype system uses an adsorbant, a material with microscopic pores that attract water molecules, to drive an evaporative cooling process.
Two sensors attached at the sides of the batteries measure the magnetic field generated by the flow of electrical current in order to determine the battery’s level of charge.
Mitsubishi Motors announced the findings of its investigation into the recent fires involving its lithium-ion batteries.
South Korea’s LG Chem plans to start production at its US car battery factory in the second half of this year, two executives told Automotive News. The Holland, Michigan manufacturing plant drew some unpleasant publicity in February, when a DOE investigation found that the production line at the plant was idle, but workers were being… Read more »
GM claims to be the first US-based automaker to manufacture electric motors and drive units in America, as it began producing these components for the new Chevrolet Spark EV at its Baltimore Operations plant in White Marsh, Maryland. The design of the motors was refined at a pilot facility in Michigan. “The era of using… Read more »
Scientists at the Paul Scherrer Institute (PSI) and the Toyota Central R&D Labs have reported a memory effect in lithium-iron phosphate (LiFePO4) batteries that appears after only one cycle of partial charge and discharge. Memory effects are well known to users of nickel-cadmium and nickel-metal-hydride batteries. If these batteries are recharged repeatedly after being only partially… Read more »
In-wheel electric drive systems are a hot topic these days. Mounting the electric motor and power electronics within a wheel assembly can improve efficiency, save space and give automakers more flexibility in body design. This week, two leaders in the field introduced new in-wheel offerings. Protean Electric announced the debut of its production in-wheel motor… Read more »
This week brought exciting news for fans of measuring current through resistive shunts. Sendyne Corp. has announced the new SFP100, a high precision current sensing IC that extends the range of accurate current measurements by at least an order of magnitude. With the Sendyne SFP100, ultra-low resistance and low-power consumption shunts can now be used… Read more »
