A new survey has confirmed something that Charged and other EV media have been saying for years: the US federal EV tax credit is about as inefficient a way to encourage EV adoption as could be imagined. Providing a “cash on the hood” rebate instead could have resulted in more EV sales at a lower… Read more »

NYC’s new school bus contract includes electric bus pilot
New York City has finalized a new contract to operate its fleet of school buses, and an electric bus pilot project is part of the plan. The five-year contract, which involves 41 companies, half a dozen municipal agencies, several labor unions, and a budget of $1.5 billion per year, will govern school bus operations in… Read more »
Jouley electric school buses arrive in Virginia as part of a V2G pilot
Bus operator Sonny Merryman, utility Dominion Energy, bus builder Thomas Built Buses and heavy-duty powertrain specialist Proterra recently hosted a celebration near Lynchburg, Virginia to officially introduce the Jouley electric school bus to public school officials from across the state. At the presentation ceremony, riders were pleasantly surprised by the silence that replaced the noise… Read more »
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 »
