Mercedes-Benz to begin production of eEconic, an electric truck for specialty municipal applications
An oft-cited obstacle to the electrification of municipal vehicle fleets is that electric versions of specialty vehicles such as refuse trucks and fire trucks are not available. Now Daimler Truck has taken a step toward filling this niche with the launch of the Mercedes-Benz eEconic, a new e-truck designed for municipal use. The key technical… Read more »
A closer look at brushed AC motors in EVs
Everything old is new again: BMW’s fifth-generation eDrive features a wound-field synchronous AC motor Brushed DC (and AC/DC universal) motors are much maligned for a number of reasons, but one of the chief—if, perhaps, somewhat exaggerated—complaints is that the graphite brushes, and the segmented copper commutator they ride on, wear out over time, all the while producing… Read more »

ONE’s hybrid battery pack combines the best aspects of two chemistries to deliver 600 miles of EV range
Q&A with ONE CTO Dr. Steven Kaye. There is a wide range of characteristics that describe the performance of any given battery chemistry: energy density, specific energy, specific power, discharge efficiency, self-discharge rate, cycle life, calendar life, and—not the least important—cost. Some types of Li-ion chemistries are really good in a few characteristics but fall… Read more »
Requirements and assembly solutions for E-mobility
Sponsored by Nordson Sealant Equipment The current supply chain situation of semiconductors and also many other, much simpler components shows how important the local production actually is. Not only car manufacturers but also suppliers, which after relocating production sites abroad or even continental relocation, are now experiencing delivery difficulties, some of them considerable. Companies like… Read more »
