Stimulated Raman Microscopy Provides Battery Ion-Transport Insight

Batteries present a major difficulty from an R&D perspective. Because they’re mostly “black boxes,” it’s very difficult to observe what’s going on inside of them while they’re functioning, and a destructive autopsy is far different and less insightful than live exploration. However, a team based at Columbia University has contributed a major solution to this […]

For decades, robots in controlled environments like assembly lines have been able to pick up the same object over and over again. More recently, breakthroughs in computer vision have enabled robots to make basic distinctions between objects. Even then, though, the systems don’t truly understand objects’ shapes, so there’s little the robots can do after […]

It’s been said that we’re in the midst of a fourth industrial revolution, driven by disruptive technological change. This revolution will impact how we communicate, interact and travel. In particular, the autonomous vehicle might produce the most disruptive change in our lifetime—at least Volvo thinks so. 1. The Volvo 360c is fully autonomous, fully electric […]

Why More-Than-Moore Power Management Is Required to Keep Up With Exponential Growth in ICT Data Consumption  Significant gains in energy efficiency are required to keep up with the exponential growth in the data consumption of Information and Communications Technology (ICT) systems: end-user devices, networks, and data centers. Moore’s Law scaling (monolithic integration in silicon) is […]

Download this article in PDF format. Battery management, like military radars and supersonic jets, is a sophisticated technology that’s been out of reach for engineers who don’t have special clearance or deep pockets—until now. Charging and fuel gauging—at the heart of every battery-management system—are critical components of any mobile or IoT application. Battery performance relies […]

The quest for improved energy density in both conventional batteries and supercapacitors sometimes takes especially interesting paths. In research supported by the Air Force Office of Scientific Research, a team at UCLA worked with other institutions (Mississippi State University, University of Nevada, Central South University) and looked to the structure of tree leaves. Both leaves […]

You will see a power blog series from me on Power Electronics in the upcoming months. These blogs will post every other week, with topics centering around power supplies. This first installment will be about the low-dropout regulator (LDO). Succinctly, a dc-dc converter is a power-supply device that does just that: Change a dc voltage to […]

Companies are beginning to acknowledge the potential of new markets and downstream revenue opportunities as they explore a more comprehensive “silicon to services” model that spans the data center to the mobile edge. More specifically, with eroding ASPs (average selling prices) and increasingly prohibitive design costs at ever lower nodes, many companies are searching for […]

Power management involves test and measurement in three different levels: • System • Subsystem • Component At the system level, there are ac and dc power analyzers. At the subsystem level, a considerable amount of test and measurement systems can ensure a power supply is working properly. Testing at the component level mostly involves the […]

Electric vehicles (Vs) are part of the fourth industrial revolution, driven by disruptive technological change. This disruption may produce upheaval and uncertainty, with winners and losers. As a result, these technologies can produce new products and new jobs, but also cause possible displacement of jobs. It appears that there will be new products and new […]

Witches with their warty green faces and ominous cackling—like those huddled around a bubbling cauldron in Shakespeare’s Macbeth—may not seem to have all that much have in common with engineers. But engineers do have this kind of uncanny—almost magical ability—to troubleshoot problems, whether it’s coaxing dead products back to life, tracking down bugs hidden deep […]

A new combination of materials developed by Stanford University researchers may aid in developing a rechargeable battery that can store the large amounts of renewable power created through wind or solar sources. With further development, the new technology could deliver energy to the electric grid quickly, cost effectively, and at normal ambient temperatures. A flow […]

Because safety-critical systems must work if there’s a power interruption of any kind, the next generation of self-driving vehicles can be expected to borrow a page from the commercial aviation industry: Provide redundancy not only for sensors and computer chips, but for the electrical architectures as well. That includes batteries, regardless of whether a 12- […]

Power management plays a vital role in transportation systems that travel on land, air, and sea. Regardless of the particular application or technology, power management regulates, controls, and distributes power throughout that system.  Land transportation includes the automotive industry, whose requirements are specific and different from most industrial and commercial applications. Some of these power-management […]

Some applications require the monitoring of power applied to a system. Microchip Technology addressed this need with the MCP39F511A, a highly integrated, single-phase power-monitoring IC intended for real-time measurement of ac and dc inputs. It detects the input voltage and automatically sets operation in the appropriate mode, either dc or ac. Separate ac and dc […]
