The US Army Research Laboratory (ARL) and Brown University researchers have teamed up to study the solid electrolyte interphase (SEI) layer that forms on the anodes of lithium-ion batteries, with particular emphasis on experimental silicon anodes. The Army is working to replace its alkaline and nickel-metal hydride field batteries with Li-ion batteries. “The Army is… Read more »

US Army microgrid features bidirectional EV chargers
It’s not just trees and money that are green – it’s also the color of military uniforms. The US Army is a pioneer in electric mobility and renewable energy, especially in the field of microgrids – small independent smart grids that can power an entire military base. Last December, the Army Corps of Engineers commissioned… Read more »
US Army base uses EVs as energy storage devices on microgrid
While many have discussed the potential of EVs to act as energy storage devices in a smart grid of the future, the day when this idea can be implemented on a citywide scale is probably pretty far off. However, a smaller, self-contained “microgrid” offers the perfect opportunity to test the concept. Microgrids are one of… Read more »
SkillFusion launches EVSE Diagnostic Technician credentialing program
As EV chargers proliferate, an army of technicians will be needed to keep them in working order (and the sooner the better). SkillFusion’s new EVSE Diagnostic Technician (EDT) Credentialing Program provides non-electricians with the needed skills and certifications to carry out specific technical work on EV chargers, such as servicing communication and networking systems. The… Read more »
Beam Global receives first European order for its EV ARC solar EV charging systems
Beam Global has received a million-dollar order from the UK Ministry of Defence (MoD) for ten EV ARC EV charging systems and one ARC Mobility trailer, to be deployed at British Sovereign Bases on Cyprus. “Beam Global’s patented solar-powered EV ARC will provide not only clean energy for British military electric vehicles in Cyprus, but… Read more »
Hyundai partners with itselectric to deploy curbside EV chargers in New York
Pity the poor drivewayless drivers, who park their cars on the street, and have no option to install EV chargers at home. Millions of car owners around the world suffer this plight, and a viable solution needs to be simple and inexpensive. Brooklyn-based itselectric offers “scalable and simple curbside EV charging that seamlessly integrates into… Read more »

GM’s “fuel cell power cubes” could replace diesel and gas generators
Automakers have invested big bucks in fuel cells over the past few years, and they’d probably be glad to find some viable applications for the technology. GM is developing ways to apply its Hydrotec fuel cell technology to power generation. GM is planning multiple Hydrotec-based power generators, all powered by GM’s Generation 2 Hydrotec fuel… Read more »
USA Rare Earth acquires permanent magnet manufacturing capability
USA Rare Earth has purchased the neodymium iron boron (NdFeB) permanent magnet manufacturing equipment formerly owned and operated in North Carolina by Hitachi Metals America. Demand for rare earth magnets is being driven by plug-in vehicles (electric motors and batteries), wind generators (direct drive generators), medical devices (personal vital sign monitors and medical imaging machines)… Read more »
A look at BMS validation testing
The battery pack is not only one of the most expensive components in an EV—it’s also incredibly complex, in some cases comprising thousands of individual cells. The tasks of preserving a battery’s efficiency, lifespan, thermal stability and safety rest upon the battery management system (BMS), an embedded controller that regulates the flow and distribution of… Read more »
