Going Off-Road With Hard-Carbon Lithium-Ion Battery Technology
Posted in Articles, News, Batteries, Power Management, Energy Efficiency, Solar Power on Sunday, 01 February 2015
EnerDel’s second-generation Mobile Hybrid Power System (MHPS) was delivered in May to the U.S. Army Corps of Engineers’ Research and Development Center in Champaign, IL. It offers a reduction in diesel fuel consumption of up to 70% “in most use cases as demonstrated by the military.” The MHPS-80, as delivered to USACE-ERDC, features an onboard 15-kW charging generator, an 80-kW·h lithium-ion battery system, power inverter, and dc input for wind and solar energy.

Aircraft with Hybrid Engine Can Recharge in Flight
Posted in News, Aviation, Batteries, Power Management, Motors & Drives, Power Transmission on Wednesday, 21 January 2015
Researchers from the University of Cambridge, in association with Boeing, have successfully tested the first aircraft to be powered by a parallel hybrid-electric propulsion system, where an electric motor and gas engine work together to drive the propeller. The demonstrator aircraft uses up to 30% less fuel than a comparable plane with a gas-only engine. The aircraft is also able to recharge its batteries in flight, the first time this has been achieved.

Hospital-Grade Standards for Power Cords and Other Power System Components for Global Markets
Posted in Features, Electronic Components, Power Management, Power Supplies, FDA Compliance/Regulatory Affairs on Thursday, 01 January 2015
While a number of countries have standards in regards to overall medical equipment, a few countries have related component requirements (e.g. plugs and cords). For the countries that do have hospital-grade or medical application standards on components, it is important to know what the requirements are so as to comply with that country or region’s rules.

Researchers Develop a Way to Control Material with Voltage
Posted in News, Batteries, Board-Level Electronics, Electronic Components, Power Management, Metals on Thursday, 04 December 2014
A new way of switching the magnetic properties of a material using just a small applied voltage, developed by researchers at MIT and collaborators elsewhere, could signal the beginning of a new family of materials with a variety of switchable properties. The technique could ultimately be used to control properties other than magnetism, including reflectivity or thermal conductivity. The first application of the new finding is likely to be a new kind of memory chip that requires no power to maintain data once it’s written, drastically lowering its overall power needs. This could be especially useful for mobile devices, where battery life is often a major limitation.

Garnet Ceramics Could Be the Key to High-Energy Lithium Batteries
Posted in News, Batteries, Electronic Components, Power Management, Energy Efficiency, Ceramics on Thursday, 04 December 2014
Scientists at the Department of Energy’s Oak Ridge National Laboratory have discovered exceptional properties in a garnet material that could enable development of higher-energy battery designs. The ORNL-led team used scanning transmission electron microscopy to take an atomic-level look at a cubic garnet material called LLZO. The researchers found the material to be highly stable in a range of aqueous environments, making the compound a promising component in new battery configurations.
