Stanford researchers demonstrate major advance in dynamic charging
Stanford engineers say they have taken a big step toward a practical system for dynamic charging, which would allow EVs to recharge while hurtling down the highway. Stanford Professor Shanhui Fan has been working on dynamic charging for some time. In 2012, he and his team published a description of a dynamic system, which they… Read more »
Seven future electric pickup trucks. Maybe.
Over the first 10 years of their existence, most modern battery-electric cars have been compact hatchbacks or Teslas. While a few are marketed as crossover utility vehicles, none have been the full-size pickup trucks that make up a huge and very profitable segment of US vehicle sales. That’s about to change. What follows is a… Read more »
Texas A&M researchers develop a method for 3D printing hard steels
Martensitic steels—materials that are both corrosion-resistant and hardenable via heat treating to a wide range of hardness and strength levels—lend themselves to applications in the aerospace, automotive and defense industries, in which high-strength, lightweight parts need to be manufactured inexpensively. Researchers from Texas A&M University, in collaboration with scientists at the Air Force Research Laboratory,… Read more »
A look at BMS validation testing
The battery pack is not only one of the most expensive components in an EV—it’s also incredibly complex, in some cases comprising thousands of individual cells. The tasks of preserving a battery’s efficiency, lifespan, thermal stability and safety rest upon the battery management system (BMS), an embedded controller that regulates the flow and distribution of… Read more »
Michigan school districts to buy 17 electric buses
Seven Michigan school districts – Ann Arbor, Gaylord, Kalamazoo, Oxford, Roseville, Three Rivers and Zeeland – will be the first in the state to purchase electric buses. The districts will receive $4.2 million from the state to cover up to 70 percent of the costs of buying 17 electric buses, along with Level 2 and… Read more »
MIT researchers demonstrate new way to make thin-film lithium-rich ceramic electrolytes
Researchers at MIT have come up with a new pulsed laser deposition technique to make thinner lithium electrolytes using less heat, which they say promises faster charging and potentially higher-voltage solid-state lithium-ion batteries. Key to the new technique for processing the solid-state battery electrolyte is alternating layers of the active electrolyte lithium garnet component (LLZO)… Read more »
California Air Resources Board mandates 100% zero-emission buses by 2040
The California Air Resources Board (CARB) has unanimously approved a rule that will move the state towards the goal of a 100-percent zero-emission bus fleet by 2040. Like most government programs, CARB’s Innovative Clean Transit (ICT) regulation has a long timeline – the process of proposals, meetings and workshops that led to this week’s final… Read more »
University of California, Irvine to convert its entire bus fleet to EVs
The University of California, Irvine has chosen electric bus manufacturer BYD to convert the Anteater Express bus fleet, which serves the college’s 1,500-acre campus and various off-campus locations, into an all-electric service. UCI undergraduates voted in 2013 to transform the Anteater Express shuttle, which is operated and funded by students, to a more sustainable fleet,… Read more »
20 electric buses in 3 Canadian cities to demonstrate OppCharge protocol
The Canadian Urban Transit Research and Innovation Consortium (CUTRIC) is leading a pilot project in which at least 20 electric buses supplied by New Flyer and Nova Bus, along with 7 overhead chargers supplied by ABB and Siemens, will demonstrate the interoperability of the OppCharge protocol. The trial’s 18 consortium partners include manufacturers, utilities, transit… Read more »
