Fig. 11: Illustration of the researched bus depot in Yinchuan.

The different colored dots in the figure indicate the GPS track points of the EBs on different routes, showing the trajectories of the EBs. The EB trajectories are grouped together at one point, which is the bus depot. EBs operating four routes are charged at this bus depot, which can use its free roof to install PV modules. This bus depot is an energy hub for charging operations, incorporating solar PV and BES.
