Next Jeep Wrangler to be available only as a plug-in vehicle
Fans of Jeeps, with their rugged, noisy, militaristic image, would seem to be unlikely buyers of EVs. But if you look at vehicle performance rather than demographic identity, a different picture emerges. As prolific EV writer John Voelcker recently noted, off-roading is actually an ideal application for EVs. “Maximum torque at extremely low motor speeds,… Read more »
BMS functional verification: the safety-first approach
Sponsored by Pickering Interfaces. Herein, we discuss the goals of BMS verification and explain how simulation with hardware-in-the-loop provides a wealth of data, saves time and is safer than working with actual live cells. We also explain how a BMS HIL test system can be created using PXI simulation modules from Pickering Interfaces. Battery Management… Read more »
Wright Electric aims to develop EV battery with 1,000 Wh/kg specific energy
Wright Electric, provider of electric propulsion systems for regional aircraft, has launched an initiative to develop batteries targeting 1,000 watt hours per kilogram (Wh/kg) pack-level specific energy. “When I founded Wright, the best vehicle batteries had [specific energy] below 250 Wh/kg,” said Jeff Engler, CEO of Wright. “Now several large manufacturers are advertising cells at… Read more »

Mercedes-Benz’s eActros 600 electric truck excels in hot-weather testing
Mercedes-Benz Trucks recently tested a prototype of its long-range electric truck, the eActros 600, in extreme heat in Andalusia, Spain. For five weeks, Mercedes engineers shook down every system on the truck, from itss electric powertrain and battery thermal management to its air conditioning system, to its fast charging capabilities, in summer temperatures of up… Read more »
Introduction to the power distribution systems for EV charging with Starline Track Busway
Sponsored by Starline. Power distribution systems must combine flexibility and robust protection for environments with dust or water, such as wet or dusty manufacturing environments, distribution centers, indoor cultivation centers, parking garages with EV charging stations, or any facility with sprinkler systems. Since 1987, Starline has been synonymous with the phrase “overhead power distribution made… Read more »
How to improve EV traction motor efficiency
A look at improving motor efficiency in two main categories: electrical and mechanical. Regular readers of Charged don’t need to be told that the typical EV drivetrain is way more efficient from battery to wheels than its ICE-based equivalent, but it is perhaps less well-known that the approximate drivetrain efficiency ranges from 75-90% for the… Read more »
