Linear Technology Corporation (Milpitas, CA) has introduced the LTC4415, a monolithic two-channel 4A PowerPath™ ideal diode device designed to reduce heat, voltage drop, and board space while preserving battery run time in power switchover circuits.
A Search Engine for Clean Energy Materials
Posted in News, News, Batteries, Energy Efficiency, Energy Storage, Renewable Energy, Solar Power, Thermoelectrics on Monday, 07 November 2011
For everything from batteries to photovoltaics, new materials are crucial to building a clean energy economy. To speed up the development cycle, Berkeley Lab and MIT researchers have teamed up to develop a new tool - called the Materials Project - which launches this month.
Ongoing Power Performance Research to Advance Electromobility
Posted in News, News, Batteries, Energy Efficiency, Energy Storage on Wednesday, 26 October 2011
The AutoTram® is as long as a streetcar and as maneuverable as a bus. It doesn’t need rails or overhead lines because it rolls on rubber tires and simply follows white lines on the street. In “Fraunhofer’s System Research for Electromobility,” the AutoTram® was used as an experimental platform. It was a component of the research collaboration of more than 30 of Germany's Fraunhofer institutes.
DC-DC Switching Charger ICs
Posted in Products, Products, Batteries, Energy Efficiency on Tuesday, 18 October 2011
austriamicrosystems (Unterpremstaetten, Austria) offers two new battery charger ICs for Li-ion batteries in mobile devices. The AS3610/11 step-down DC-DC chargers offer fast and highly efficient charging of Li-ion batteries with up to 1.25 A output current. The ICs include safety and protection features, internal current measurement, and USB Host/OTG (on the go) boost mode operation.
Technology Reduces Production Costs of Lithium-ion Cells
Posted in News, News, Batteries, Energy Efficiency on Monday, 17 October 2011
A development by engineers of Germany's Karlsruhe Institute of Technology (KIT) is inspired by nature. To fill the porous electrodes of lithium-ion batteries more rapidly with liquid electrolyte, they use a physicochemical effect that also provides water transport in trees. The new process increases the throughput of battery production and reduces investment costs.
Innovative Electric Aircraft Collects Aviation Prize
Posted in News, Videos, News, Batteries, Energy Efficiency on Friday, 07 October 2011
The 2011 CAFE Green Flight Challenge has a winner! NASA awarded a $1.35-million first place prize to team Pipistrel-USA of State College, PA. The team's electric Taurus G4 aircraft achieved the equivalency of more than 400 miles per gallon. The second place prize of $120,000 went to team eGenius, of Ramona, CA.
Crash-Resistant Battery Housing for Electric Cars
Posted in Building Technologies, News, News, Batteries on Thursday, 06 October 2011
Fraunhofer scientists working on electronic drives have replaced a battery box for lithium-ion batteries with a lightweight component. Not only does the housing save weight and sustain no damage in an accident – for the first time ever, it can also be mass-produced.
