Usually, bus stop m is equipped with one charging pile with a charging power of P m kW, k m = 1. For terminal stations, k m > 1. When all the piles are occupied, the newly arrived bus cannot be connected to the grid. The specific charging start time will be determined by the charging end time of the buses occupying the charging piles.
