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

Green Car Congress

A prototype self-driving truck under development by Scania and Swedish research universities has tested successfully at speeds of up to 90 km/h (56 mph). Clothoids are used for road design since their curvature vary linearly with the path arc-length. 2983-2990 doi: 10.1109/ECC.2015.7330991. Trincavelli, J. Mårtensson and B.

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.
