Wolfspeed, a pioneer of silicon carbide (SiC) power products, has expanded its C3M platform to include a 1,200 V MOSFET. The new device is designed to enable an increase in frequency while maintaining efficiency, lowering system cost, reducing circuit EMI, and enabling 99% efficiency levels in three-phase power factor correction circuits. The device uses Wolfspeed’s… Read more »

New Flyer electric bus deliveries increased by 48% in 2016
New Flyer is one of North America’s largest bus builders, and zero-emission buses (ZEBs) are a growing part of its business. In 2016, the company delivered 213 “equivalent units” as zero-emission buses (one standard transit bus or motor coach equals one equivalent unit, one articulated bus equals two). This represents 8.3% of New Flyer’s total… Read more »

Volkswagen invests in eRoaming provider Hubject
Hubject is a Berlin-based company that provides a solution for the exchange of data among charging networks. Hubject’s eRoaming platform is analogous to the networks that enable ATMs, mobile phones and other conveniences of modern life to work together smoothly. Hubject was founded in 2012 by a group of companies including BMW, Daimler, Bosch and… Read more »
California city to deploy 10 GreenPower electric buses
GreenPower Motor Company has announced that the City of Porterville will deploy 10 of the company’s EV350 40-foot electric transit buses, as well as charging infrastructure including 11 charging stations, supported by a $9.5-million grant from the California Air Resources Board. CARB’s award to Porterville was one of nine awards from the Zero-Emission Truck and… Read more »
Lux Research: Recycling is preferable to reuse for retired EV batteries
Companies around the world, including Nissan, Renault, Daimler, BMW and Siemens, are investigating ways to reuse EV batteries after they retire from the road. Bloomberg analysts recently predicted that by 2025, there will be 29 GWh of used EV batteries available, and that a third of these will enjoy second lives in the stationary storage… Read more »
NASA inaugurates new Electric Aircraft Testbed
Commercial electric aircraft may lie far in the future, but NASA is conducting research on several fronts. Engineers at the NASA Electric Aircraft Testbed (NEAT) at NASA’s Glenn Research Center ran the new facility’s first test in September. Dr. Rodger Dyson led a team that successfully tested a 600-volt electrical power system that could realistically… Read more »
Bloomberg: Second-life EV battery storage will total 26 GWh by 2025
In a new report for clients, Bloomberg New Energy Finance (BNEF) forecasts that there will be 29 GWh of used EV batteries available in 2025. This far exceeds the size of the current stationary storage market. Of this, almost a third will get a second life as stationary storage (10 GWh), bringing the cumulative installed… Read more »
The inevitability of electric buses
Electric transit buses enter the fast-follower market stage as the leaders work to remove the last barriers to adoption. Q&A with Proterra’s Ryan Popple and ABB’s Daan Nap on the state of the market and charging standards in North America and Europe. With each passing year, more decision makers are realizing that city buses are an… Read more »
Improving aerodynamic modeling: Combining airflow dynamics with vehicle-handling models
Tuning a vehicle’s aerodynamic features is nothing new. Engineers have been using wind tunnels for decades, and more recently they’ve also employed computational fluid dynamics (CFD) software to reduce drag, minimize noise and increase stability by preventing undesired lift forces. In the expanding world of EVs, car builders are doubling down on efforts to push… Read more »
