Abstract
Increasing environ mental awareness has led to the wide use of electric vehicles. Due to the low energy density, batteries in electric vehicles must be frequently switched. Therefore, the battery swap station location problem, which determines the number, location, and size of battery swap stations, is vital to the operations of electric vehicles. The battery swap station location problem may be examined from different viewpoints according to whether the stations are operated by the government, by a private firm, or by several private firms. Hopefully, more future research efforts would be directed to this practical new problem.\r\n
