Nidec has been engaged in the manufacture of reduction gearboxes and pressing machines through its subsidiary Nidec-Shimpo. After completion of the acquisition, Mitsubishi Heavy Industries Machine Tool will become Nidec-Shimpo’s third main business…. Read more »
New emissions scandal? Tests show PHEVs emit more pollution than claimed
Sometimes it seems automakers will try any powertrain technology in order to avoid selling battery-electric vehicles. First diesels, then hydrogen, were touted as ways to reduce CO2 emissions while still maintaining the fill-er-up-with-fossil-fuel business model (and continuing to crank out the colossal SUVs that carmakers claim consumers crave). Many electric purists have long suspected that… 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 »
China cuts EV subsidies—Tesla Model 3 exceeds price limit
China has announced a cut to its subsidies on new energy vehicles (NEVs), effective immediately. It’s been something of a rollercoaster ride for the subsidies of late. In 2015, the government announced plans to end the subsidies this year. In January, it said there would be “no significant cuts” this year. In March it confirmed… Read more »
Workhorse C-Series electric delivery trucks earn EPA Certificate of Conformity
Electric truck maker Workhorse Group (NASDAQ: WKHS) has been around for a while—Charged wrote about the company’s plug-in pickup back in 2017—and it continues to make steady progress. Now the company has announced that its new C-Series electric delivery trucks have each received an EPA Certificate of Conformity, confirming that the new vehicles conform to… Read more »
MIT team develops novel solid electrolytes and pure lithium anodes
New research from MIT could lead to batteries that pack more power per pound and last longer. A new paper co-authored by Yuming Chen and Ziqiang Wang at MIT explores the idea of using pure lithium as the battery’s anode. The design is part of a concept for developing safe solid-state batteries by dispensing with… Read more »
California and 7 other states commit to faster electrification of medium- and heavy-duty vehicles
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 »
