MIT analysis finds current EVs could replace ~90% of personal vehicles now on the road based on driver’s energy consumption

Green Car Congress

A study by a team at MIT has concluded that roughly 90% of the personal vehicles on the road in the US could be replaced by an electric vehicle available on the market today, even if the cars can only charge overnight. Together, the two datasets encompass millions of trips made by drivers all around the country. Chang & Jessika E.

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. In the simulations, battery-powered vehicles, particularly the 40 kWh ones, needed more frequent and longer trips without passengers to get to recharging stations.

UCSD team suggests building more fast-charging stations based on study of pandemic impact on EV charging

Also as expected, charging at the campus’ medical center was less impacted as medical facilities continued most in-person operations and healthcare workers and patients kept using those charging stations. As expected, charging declined significantly once most campus operations became remote. This reflects nationwide trends.

Berkeley study finds self-driving electric taxi fleets in Manhattan would deliver significant cost and environmental benefits

Green Car Congress

The EV industry is focusing on the personal car market, trying to make the range as large as possible. We found plenty of times during the day when a portion of taxis could slip off to recharge, even if just for a few minutes. The standard now is 200 miles. We suspected you wouldn’t need as much for taxis. Bauer, Jeffery B.

EV charging is changing, Part 1: How automakers’ disappointment in Electrify America drove them into Tesla’s arms

Charged EVs

Every person we spoke with wanted to talk—to vent, even—and to share conversations they’d had and anecdotes they’d heard from others in the business. Fury at Electrify America It’s hard to overstate the disgust and anger at Electrify America among virtually every person we interviewed. No further details are known as yet.

Consumers’ attitudes toward plug-in vehicles: control over convenience

Green Car Congress

For example, respondents seemed to think that a traditional cable was the best way to recharge, even though inductive wireless charging could enable a self-fueling vehicle. A person wouldn’t be required. We noticed that people tend to prefer the things that give them the most control, rather than the most convenience.
