How to protect an EV’s on-board charger from transient grid surges
Sponsored by TTI. The automotive environment is one of the most severe environments for electronics. Today’s vehicle designs proliferate with sensitive electronics, including electronic controls, infotainment, sensing, battery packs, battery management, electric vehicle powertrains, and on-board chargers. In addition to the heat, voltage transients, and electromagnetic interference (EMI) in the automotive environment, the on-board charger… Read more »
Aqua Metals is building a more sustainable battery recycling ecosystem
Q&A with Aqua Metals execs Steve Cotton and David Regan Regardless of the claims made in Facebook memes, Li-ion batteries are eminently recyclable, and current recycling methods cause far less environmental damage than the well-documented depredations of the petroleum industry. However, as sustainability is central to the mission of the EV industry, we need to… Read more »
2024 Dodge Charger Daytona: the ‘Brotherhood of Muscle’ goes electric
The Charger sedan and Challenger coupe exuded testosterone, courtesy of snarling V-8s. Dodge says the EVs that replace them will be just as noisy. The 2024 Dodge Charger Daytona is a Detroit anomaly: it’s a passenger car in an age of trucks and SUVs, it’s battery-electric when U.S. makers seem to be in an EV… Read more »
The heavy-duty electric truck market could break out in 2024
Electrifying heavy-duty trucks is essential if we’re to fight climate change and air pollution, but the pace of the transition has been painfully slow—many, many pilots, but few truly large-scale orders. For example, shipping giant Schneider acquired 92 Freightliner eCascadias in 2023—a good start, but only that, considering that the company currently operates over 10,000… Read more »

Dynexus uses pattern recognition to make a powerful battery health measurement technique even better
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 »
