Routing decisions of a hybrid vehicle on electric road networks
收藏 引用
IFAC-PapersOnLine 2022年 第10期55卷 227-232页
作者: Alejandro Gutierrez-Alcoba Roberto Rossi Belen Martin-Barragan Tim Embley Business School University of Edinburgh Edinburgh UK Costain Group Plc. Maidenhead UK
An electric road system (ERS) is a road in which vehicles can travel powered from the electrical grid. Deployed at scale, this technology reduces or eliminates the need for electric vehicles (EVs) to stop for rechargi... 详细信息
