QM Power and University of Kentucky demonstrate 50 kW/liter electric motor; DOE 2025 power density goal

Green Car Congress

QM Power and the SPARK Lab at University of Kentucky shared the combined results of a large-scale, multi-objective design optimization study, and lab testing of a prototype motor designed to meet the 2025 power density goals set by the US Department of Energy (DOE). An open frame lab prototype was designed and manufactured by QM Power.

Self-driving mining truck stable at 90 km/h; clothoid-based model predictive control

Green Car Congress

Clothoids are used for road design since their curvature vary linearly with the path arc-length. The truck’s calculation model thus has to be more complex and resource intensive. Resources.

Study identifies main culprit behind lithium metal battery failure; counters conventional wisdom

Green Car Congress

For example, in an electrolyte specially designed by Meng’s collaborators at General Motors, lithium deposits as dense, column-shaped chunks. The answer has to do with how lithium deposits on the anode when the cell is charging. Some electrolytes cause lithium to form micro- and nanostructures that boost cell performance.
