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

Green Car Congress

The analysis indicated that electrified fleets had 40-45% lower greenhouse gas costs per trip compared to the gasoline-powered version. In the simulations, battery-powered vehicles, particularly the 40 kWh ones, needed more frequent and longer trips without passengers to get to recharging stations.

Siemens Exploring Charging at Up to 300 kW for EVs; 6 Minutes for an EV Recharge

Green Car Congress

The long-term goal is to achieve up to 300 kW of charging capacity—enabling a quick recharge in roughly 6 minutes. The development engineers are also investigating how the constant switching on and off of the batteries affects the power grid; the harmonics this generates could knock the grid out of sync.

Hawaii study finds vehicle-to-grid discharge detrimental to EV batteries

Green Car Congress

Results of a study by a team at the Hawaii Natural Energy Institute, SOEST, University of Hawaii at Manoa, suggest that the additional cycling to discharge vehicle batteries to the power grid in a vehicle-to-grid (V2G) scenario, even at constant power, is detrimental to EV battery cell performance.

CMU policy briefs outline benefits and potential for adoption of electrified vehicles in the US

Green Car Congress

Researchers at Carnegie Mellon University (CMU) have published two new policy briefs, along with accompanying videos, about the benefits of electrified vehicles and the potential for their adoption in the US. The briefs condense the findings of a number of recent papers coming out of the CMU group led by Professor Jeremy Michalek.
