California is joining with seven other states to develop an action plan to put hundreds of thousands more zero-emission trucks and buses on the roads. This new medium- and heavy-duty vehicle collaborative effort will be implemented through the multi-state ZEV Task Force, and will be facilitated by the Northeast States for Coordinated Air Use Management… Read more »

Rivian’s VP of Propulsion: Thermal issues are the dominant limiting factor for maximizing EV performance
Charged recently chatted with Rivian’s VP of Propulsion Richard Farquhar to learn more about the design and development of the company’s unique electric platform (read the whole story in our upcoming issue). Farquhar spent 15 years as Powertrain Director at McLaren Automotive, designing and developing some of the highest-performance propulsion systems in the world for… Read more »
Lamborghini and MIT patent a new material for supercapacitors
Lamborghini and the Massachusetts Institute of Technology (MIT) have patented a new synthetic material that the carmaker hopes will serve as the technological base for a new generation of supercapacitors. The two organizations began working together in 2017, when they produced the Terzo Millennio concept car. With support from Lamborghini’s Concept Development Department, a research… 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 »
Sumitomo and Kansai University develop technology to generate power from static electricity in tires
Sumitomo and Professor Hiroshi Tani of Kansai University have developed a new technology to generate electricity from the rotation of a tire. By installing a power generating device (or Energy Harvester) inside a tire, researchers were able to convert static electricity into clean energy. The new device, which Sumitomo calls the ‘SMART TYRE CONCEPT’, takes… Read more »
Mayors from 127 cities commit to purchase over 2,100 EVs by 2020
Mayors from 127 cities joined the Climate Mayors EV Purchasing Collaborative during the Climate Mayors Summit in Honolulu, Hawaii last month, committing to purchasing more than 2,100 EVs by 2020. To assist in the transition towards electric school buses, the Collaborative announced it will place a competitive bid on electric school buses by the end… Read more »
Proterra and Mitsui create $200-million credit to scale battery leasing program for electric buses
Electric bus manufacturer Proterra has partnered with Japanese conglomerate Mitsui to create a $200-million credit to scale up Proterra’s battery leasing program. Proterra customers will be able to purchase an electric bus and lease the batteries over the 12-year lifetime of the bus. Through the battery lease, Proterra says the initial capital expense for the… Read more »
MIT creates hybrid cathode designed to boost energy capacity of Li batteries
Researchers at the Massachusetts Institute of Technology (MIT) and in China say they’ve developed a new version of the cathode. The researchers describe the cathode as a “hybrid,” since it combines aspects of intercalation-type and conversion-type cathodes to increase gravimetric energy density (per-pound energy output) and volumetric energy density (per-liter energy output). The cathode has… Read more »
Tesla revises pricing options, reintroduces software-limited battery packs
After Tesla recently discontinued the 75 kWh versions of Models S and X, some speculated that it was a precursor to replacing the battery pack used in those models with a redesigned pack based on the newer 2170 cells used in Model 3. However, that doesn’t seem to be in the cards for the moment… Read more »
Sumitomo Electric’s new generation of SiC transistors offer low on-state resistance
Sumitomo Electric’s new V-groove superjunction transistors, which it developed through a joint research project with the National Institute of Advanced Industrial Science and Technology (AIST) use silicon carbide (SiC) semiconductors, and the company claims they offer the lowest on-state resistance yet achieved in an SiC transistor. Sumitomo has already developed V-groove MOSFETs that use a… Read more »
