Model Y: Tesla’s latest model is its most refined—and it continues to improve
Every Tesla model has arguably been a historic vehicle. The Roadster was the first EV to offer the performance and aesthetics that attract car buyers. Model S was the first mass-produced EV to deliver this combination, and Model X delivered it as an SUV. Model 3, the culmination of the company’s master plan, was the… Read more »
How to ensure EV traction motor magnets aren’t pushed beyond their operating limits
Avoiding motor demagnetization: John Wanjiku, Technical Specialist at Mentor Graphics, explains the goals of a detailed traction motor design analysis. Neodymium permanent magnets are used in EV traction motors because of their powerful magnetic fields and relatively strong resistance to demagnetization, but they tend to lose their magnetism when exposed to excessive operating temperatures, opposing… Read more »
The emerging “non-utilities”—EVs are helping new players in the energy marketplace.
Gordon Feller serves on the boards of several non-profit organizations focused on the future of greener mobility. He formerly served as President Obama’s appointee to a US Federal Commission established to assess emerging energy-focused digital technologies. Dramatic pricing changes, shifting cost structures, new demand curves and technologies that enable efficient decentralization are driving a dramatic… Read more »

Indianapolis EV-sharing project folds after four years
In 2015, French conglomerate the Bolloré Group opened an all-EV car-sharing service called BlueIndy in Indianapolis. Alas, BlueIndy announced plans to close last December, and terminated operations in May. “This difficult decision to end the service has been made because we did not reach the level of activity required to be economically viable,” said BlueIndy… Read more »
New study: EV fuel cost savings vary widely across the US
EV drivers can save as much as $14,500 on fuel costs over 15 years compared to driving a legacy vehicle. That’s the conclusion of a new analysis conducted by researchers at the DOE’s National Renewable Energy Laboratory (NREL) and Idaho National Laboratory (INL). The new report, Levelized Cost of Charging Electric Vehicles in the United… Read more »
Battery500 Consortium steadily increases energy density and cycle life of Li-metal cells
Launched in 2017, the Battery500 Consortium is a multi-institution program working to develop next-generation lithium metal anode cells delivering gravimetric energy density of up to 500 Wh/kg. The Battery500 team is composed of scientists and engineers from four national laboratories and five universities. Two of the researchers on the team, Professor Stanley Whittingham of Binghamton… Read more »
