Design Trial Production, and Performance Evaluation of an Electric Busfor Running on Expressways

Our research group designed and made two trial production for two electric buses, a small-sized bus for driving on ordinary roads and a medium-sized bus for driving on expressways. Approximately one-year verification test was conducted in the Metropolitan Expressway Bay Shore route and surrounding areas in Japan. In this paper, analyzed results focused on the regenerative energy while traveling on expressways compared to ordinary roads made by heavy-duty electric vehicles will be summarized.
