Researchers at MIT and the DOE’s Brookhaven National Laboratory have developed a method for stabilizing the interfaces between the electrolyte and cathodes in solid-state batteries during the sintering process. Based on research reported in Advanced Energy Materials, the team found that when temperatures are above a few hundred degrees Celsius, carbon dioxide and reactions unfold… Read more »

Why is Tesla no longer including mobile charging cables with its vehicles?
First-time EV buyers are famously nervous about charging, which is one reason that most new EVs come with a portable charging cable—it’s reassuring to know that you can plug your new car in as soon as you take it home, without having to deal with charger installation right away. Some drivers find the portable adequate… Read more »
How to test the functionality and safety of EV charging stations, easily and reliably
Sponsored by Fluke Easy EVSE safety testing and troubleshooting with the Fluke FEV100 Test the safety and performance of type 1, level 1 or level 2 electric vehicle ac charging stations (EVSEs) with the Fluke FEV100. This test adapter simulates the presence of an electric vehicle, allowing you to conduct tests in combination with appropriate… Read more »
Are solid-state batteries always safer than Li-ion?
Many in the EV industry see solid-state batteries as the future, and one of the reasons is that the more stable solid electrolyte is expected to be safer than current liquid electrolytes. However, new research indicates that the picture may be more complex. A recent study led by the DOE’s Sandia National Laboratories, published in… Read more »
Do EV brakes and tires cause more particulate pollution?
Huge amounts of misinformation about EVs are churned out each day—and some of this has been coming from the UK’s top environmental official. Environment Secretary George Eustice, who said last November that he doesn’t own an EV or a heat pump, because “the technology is not quite there yet,” recently told members of a parliamentary… Read more »
2022 GMC Hummer EV Edition 1 first drive: five tons of fun
The rebooted electric Hummer is an absurd vehicle, in some ways, but it’s an extremely well-executed absurdity. How do you review a 5-ton electric truck that accelerates from 0 to 60 mph in about 3 seconds? No other vehicle on the market is even close to direct competition. And comparing it to mass-market EVs like… Read more »
Argonne collaborates with NUMiX Materials on battery recycling and biofuel research
Researchers at the DOE’s Argonne National Laboratory have collaborated with sorbent development company NUMiX Materials to investigate the use of a process called capacitive deionization to recycle automotive batteries and produce biofuel. Capacitive deionization separates nickel, manganese and cobalt from other battery materials by relying on their electrical charges. According to Argonne Environmental Engineer Lauren… Read more »
Measuring Electrical Power In Confined Vehicle Space
Whether early or late in the xEV development cycle, installing in-vehicle instrumentation for the accurate measurement of electrical power has been a challenge, until now. Accurate competitive vehicle analyses or production validation requires accessing cables’ inner conductors or busbars inside high-voltage components. CSM’s measurement technology has advanced to include new variants of it’s very successful… Read more »
The Power Surge: An Electric Vehicle Roundtable
As the electric vehicle industry continues to boom, manufacturers are tasked with navigating a challenging innovation and supply chain landscape. Product developers are moving as quickly as possible to launch new technologies, and supply chains are quickly scaling to meet production demand that is projected to sharply grow through 2025 and beyond. Many challenges still… Read more »
Selecting The Correct Measurement Technology For Your EV Test
Low-speed or high-speed? CAN or EtherCAT? Time aligned or syncronized? Low voltage or high-voltage? Test bench or on-vehicle? Which technology for electrical current? With or without vehicle bus? Can I include video? What about GPS data? Which software do I use to analyze all this data? The list of questions and challenges associated with the… Read more »
