New study probes cold-weather effects on electric bus range

摘要

The Center for Transportation and the Environment (CTE) with the Midwest Hydrogen Center of Excellence (MHCoE), Cleveland State University (CSU), and the Stark Area Regional Transit Authority (SARTA) have released a study evaluating the relationship between ambient temperature and fuel economy for zero-emission buses. This study builds upon previous efforts by incorporating daily-level data into the analysis, allowing the team to capture extreme temperature values that would be masked in an evaluation of monthly data. All transit buses, regardless of fuel source, experience some loss of range in extreme weather. As transit agencies plan to replace their traditional diesel-fueled buses with zero emission buses, they will need to consider the effects of extreme weather on the new buses replacing their existing fleets.
