Battery cell company Zenlabs Energy has announced the results of energy and power testing on its new large-format pouch cells as part of broader testing performed by independent third-party test lab Energy Assurance. Designed for the electric aviation market, the new large-format cells have a 32 Ah capacity. In 12C rate testing involving about 394… Read more »
Should public charging providers charge by the minute, or by the kilowatt-hour? Most agree that the per-kWh system is fairer, as it charges the customer for the energy that’s actually dispensed, and isn’t dependent on charging speed, over which the customer has no control. The per-minute pricing model persists in some states, because of state… Read more »
Is EV range really the barrier to adoption that many assume it is? Certainly, it tends to be the second thing (after charging) that the EV-curious ask about, and most of us have had conversations with skeptics who seem to have exaggerated notions of how much range they need (a friend of mine once told… Read more »
King County Metro, which operates a fleet of 1,540 buses in the Seattle region, is conducting a charging infrastructure pilot to test the capabilities of high-power plug-in and overhead chargers from three manufacturers—ABB, Siemens and Heliox. As part of the project, the agency implemented The Mobility House’s energy management solution ChargePilot, which features load management… Read more »
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 »
Siemens has provided North Carolina-made charging infrastructure for two of the state’s largest transit operators, GoRaleigh and the Charlotte Area Transit System. Siemens eMobility manufactured the chargers at its Wendell, North Carolina manufacturing hub. GoRaleigh operates 27 bus routes in the state capital. Last year, the agency took delivery of five Proterra electric buses. Siemens… Read more »
The Nissan LEAF is the elder statesman of the EV world—it’s not the most glamorous car you can buy, but it’s an affordable workhorse that has benefited from 12 years of incremental improvement. Now Nissan has released some details of the refreshed 2023 LEAF, ahead of its official debut at the 2022 New York International… Read more »
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 »
Nissan has unveiled a prototype production facility for laminated all-solid-state battery cells, which the company aims to bring to market in 2028. This prototype facility, within the Nissan Research Center in Kanagawa Prefecture, is designed to promote the development of solid-state-batteries. Nissan plans to establish a pilot production line at its Yokohama Plant in 2024,… Read more »
Circuit protection manufacturer Littelfuse has introduced a new thyristor product line, which is designed to safeguard exposed surfaces such as RS-485 data interfaces and AC/DC power supplies in factory automation systems, energy storage systems, power distribution grids and EV charging systems. The Pxxx0S3N SIDACtor Protection Thyristor is housed in a DO-214AB (SMC) package, and supplies… Read more »
