Study finds all-electric rideshare fleet could reduce carbon emissions, but increase traffic issues

Green Car Congress

But the cars and SUVs used in these situations drive more miles each year than a typical personal vehicle, contributing a higher proportion of greenhouse gases to the environment. The researchers collected simulated rides provided by three fleets: gasoline-powered, and electric-powered with either 40 kWh or 60 kWh battery packs.

Penn State team devises new control strategy to enhance EV battery performance when driving in cold temperatures

Green Car Congress

Researchers at Penn State, with a colleague from EC Power, have devised a new control strategy that can rapidly restore EV battery power and permit full regeneration while driving at temperatures as low as −40 °C. The strategy involves heating the battery internally during regenerative braking and rest periods of driving.

4,000 Robots Roam the Oceans, Climate in Their Crosshairs

Cars That Think

Wijffels: They spend 90 percent of their time at 1,000 meters below the surface of the ocean—an environment where it's dark and it's cold. And so, if we compare a freshly calibrated float’s profile with an old one that might be six or seven years old, we can make important comparisons. You mentioned batteries.
