The Good And Bad Of Bi-Directional Charging
By Marie C. Baca and Ed Sperling - 11 Jan, 2023 - Comments: 2

Auto OEMs are starting to offer bi-directional charging in EVs, allowing batteries to power homes during outages or wherever else it is needed, and to smooth out any hiccups in the grid. But this technology also can shorten the lifetime of batteries, and it can open the door to more cyberattacks. The idea behind bi-directional charging is simple enough. EVs can store huge amounts of power, a... » read more

Always-On Energy Challenges
By Ed Sperling - 14 May, 2015 - Comments: 0

The roar over the Internet of Things these days is almost deafening. Inside of China, everything being made for the domestic market is smart-ready. And companies ranging from watchmakers to appliances to automotive manufacturers are building connectivity into everything. The problem is that in order for it to work as planned—to communicate with other devices and send alerts to consumers or... » read more

Dark Data
By Ed Sperling - 12 Mar, 2015 - Comments: 0

Last month the National Resources Defense Council updated its study on data centers. The numbers themselves are rather mind boggling, and the NRDC has done an exceptional job over the years in ferreting out the biggest, baddest culprits of wasted energy. Witness the 2011 report on set-top boxes, which is finally beginning to yield changes in set-top box designs. The data center report is eq... » read more

Putting Energy In Perspective
By Ed Sperling - 22 Nov, 2013 - Comments: 0

The resurgent interest in 2.5D stacked die, the introduction of ultra-low-power memory and the relentless focus on low power for the Internet of Things are rather predictable progressions to engineers working in the semiconductor industry. What’s less obvious is how these changes are filtering out into the rest of the market and where it needs to go next. While many people have been talkin... » read more

Machine Talk
By Ed Sperling - 03 May, 2013 - Comments: 0

The Internet of Things raises some interesting questions that have never been fully addressed in semiconductor design. For instance, how do you assess the necessary performance for any particular thing? And how long is another thing willing to wait for information to be passed along? These sound like fairly basic engineering questions—until you consider that the Internet of Things is actua... » read more
