Argonne study finds BEVs can have lowest scheduled maintenance costs, but highest cost of driving

Green Car Congress

Researchers at Argonne National Laboratory, with colleagues from Lawrence Berkeley, Oak Ridge, and National Renewable Energy labs, and the University of Tennessee, have published a comprehensive analysis of the total cost of ownership (TCO) for 12 sizes of vehicles ranging from compact sedans up to Class 8 tractors with sleeper cabs.

Penn State Li-ion battery design could charge an EV in 10 minutes; asymmetric temperature modulation

Green Car Congress

Penn State researchers have developed a lithium-ion battery that charges at an elevated temperature to increase reaction rate but keeps the cell cool during discharge, showing the potential to add 200 miles of driving range to an electric car in 10 minutes. Wang and the team found that the batteries preheated to 60 ?C

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

Green Car Congress

They used the model and the data to estimate the life cycle air pollution, greenhouse gas, and traffic externality benefits and costs of serving rides based on Chicago TNC trip data from 2019 to 2022 with fully electric vehicles. A paper on their work is published in the ACS journal Environmental Science & Technology. —Mohan et al.

Independent study confirms cost savings & emissions advantages for heavy-duty trucks running ClearFlame’s engine technology

Green Car Congress

ClearFlame’s solution, grounded in technology developed during doctoral studies at Stanford University and validated using more than $3 million in grant funding, addresses this problem by elevating combustion temperatures in order to enable use of non-traditional fuels without sacrificing performance. per mile, lower than electric by $0.97

Study finds EVs are traveling less than half the US fleet average

Green Car Congress

A team from the University of Chicago, University of California, Davis, and UC Berkeley combined billions of hourly electricity meter measurements with address-level EV registration records in California—home to about half of the EVs in the United States. The takeaway here is not that EVs should never or will never be our future.

U-M researchers challenge USPS EV environmental study

Green Car Congress

A new University of Michigan study finds that making the switch to all-electric mail-delivery vehicles would lead to far greater reductions in greenhouse gas emissions than previously estimated by the US Postal Service (USPS). The USPS analysis of projected operating emissions was based on estimated per-mile emissions rates.
