Overhead chargers on key bus routes in Madison, Wisconsin are enabling the zero-emissions vehicles to run despite freezing conditions.
From the article:
Metro Transit, which provides about 9.1 million rides annually, installed overhead chargers on key routes, allowing buses to quickly top off at several stops. Improved battery capacity also lets them go further between plug-ins. The real test came January 23, when the temperature dropped to -4°F, shutting down the University of Wisconsin-Madison — but the buses kept running. [...] Just a few years ago, electric buses routinely faltered in cold conditions, reinforcing doubts about whether they could replace diesel and natural gas-burning fleets in northern cities. Now, with better batteries and strategically placed chargers, Madison is at the forefront of a small but growing number of cities testing whether those doubts still hold. Making the technology work through a long Midwestern winter could reshape how others approach electrification. Some 3.6 million commuters nationwide rely upon buses to get around. With transportation accounting for roughly 28 percent of the nation’s greenhouse gas emissions, transit agencies are looking for alternatives to polluting machinery that creates a particular health risk around bus stops. Madison is among more than 100 U.S. cities that have pledged to reach net-zero emissions by 2050. Electric buses are key to that goal.
