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 Postal Service has not commented on the U-M study. Earlier post.). The USPS estimate was 10.3

NREL study finds most depot charging could accomodate short-haul heavy-duty electric trucks without upgrades

Green Car Congress

In most cases the existing technology grid can accommodate truck charging at depots. That perception is shifting, and our research suggests that certain short-haul operations can be electrified today with relatively low-power depot charging that won’t overwhelm the grid. 100 kW/vehicle) for the fleets studied.
