Measuring battery health and safety continuously is an important challenge—lithium-ion batteries can experience several challenges over their lifetimes such as unintended capacity loss, short circuits and thermal runaway. In 2011, Idaho National Laboratory researchers developed a new technology for measuring battery health and safety. By sending multiple waves of electrical current simultaneously through a battery,… Read more »

Over $500 million investment in US EV charger plants announced since 2021
As regular Charged readers know, the US Inflation Reduction Act has spurred a tidal wave of investment in battery plants, as well as mines and processing facilities for critical battery minerals. EVSE manufacturers have also been joining the party (or “lining up at the trough,” as a fiscal conservative might put it). The DOE’s Vehicle… Read more »
Why are public EV chargers so unreliable? The industry’s history provides clues.
The parlous state of public EV charging is—among other things—a public relations nightmare that’s surely holding back wider EV adoption. A number of automakers and other EV industry players seem to be convinced that ceding control of the US public charging scene to Tesla, whose Supercharger network is by all accounts far more reliable than… Read more »
Bidirectional and regenerative EV test equipment: technical gains with environmental benefits
Sponsored by Chroma Systems Solutions. Reducing the carbon footprint and optimizing thermal cooling are paramount in modern manufacturing and have become significant criteria for selection and deployment of automated test equipment. In addition, budget constraints could be circumvented by the use of multi-purpose instrumentation. Last but not least, replenishing dissipated power to the grid will… Read more »
Energy expert: Updated US Hydrogen Strategy is better, but still designed to prop up the fossil fuel industry
Michael Barnard writes on a wide variety of e-mobility and renewable energy topics. In a recent article for CleanTechnica, he discusses the latest edition of the US National Clean Hydrogen Strategy and Roadmap, a policy document that the DOE produces and updates periodically. Barnard’s piece is a detailed and highly technical discussion of a complex… Read more »
How charge management can reduce OpEx and CapEx for EV fleet projects
Q&A with The Mobility House Business Development Manager Sam Hill-Cristol If there’s one topic that everyone in the EV infrastructure field is talking about these days, it’s charge management. As organizations of all sizes electrify their vehicles, they often find that power consumption is a major constraint. Charging stations, especially those that serve large fleets… Read more »
A closer look at high-power interconnects and disconnects
In the electrical/electronic world, the terms interconnect and disconnect both refer to a means of joining two sides of a circuit together. The subtle—and entirely informal—difference is that an interconnect is directly or manually operated (inserting a plug into a jack, for example) while a disconnect is indirectly or automatically operated, for example the moving… Read more »
NXP introduces new series of microcontrollers for EV control applications
NXP Semiconductors has introduced its S32K39 series of automotive microcontrollers (MCUs) for EV control applications. The company says these MCUs include networking, security and functional safety capabilities beyond those of traditional automotive MCUs. The S32K39 MCUs are designed for the intelligent and high-precision control of traction inverters that convert the EV battery’s DC power to… Read more »
PG&E to offer vehicle-to-grid export rate for commercial EVs
Vehicle-to-grid (V2G) technology promises to be a true win-win: a powerful grid balancing resource for utilities and a source of incremental income for EV owners (electric school buses seem to be an ideal use case). But before V2G can really take off, there needs to be a system for utilities to compensate EV fleet operators… Read more »
2022 Lucid Air: The makers of the first 500-mile EV should be taken seriously
Created by engineers with years of EV experience, the 2022 Lucid Air is a stunning debut that confronts Tesla—and Mercedes-Benz—with a new competitor. It’s been a long time coming, but the 2022 Lucid Air has been worth the wait. The new carmaker’s all-electric luxury sedan not only competes directly with the aging Tesla Model S,… Read more »
