Charging piles in the bus depot provide charging services to multiple electric bus (EB) routes operating in the area. As charging needs may overlap between independently operated routes, EB fleets often have to wait in line for charging. However, affected by the ambient temperature, the length of the waiting time will cause the battery temperature...

Replacing conventional buses with electric buses is in line with the concept of sustainable development. However, electric buses have the disadvantages of short driving range and high purchase price. Many cities must implement a semi-electrification strategy for bus routes. In this paper, a bi-level, multi-objective programming model is established...

... Time-based constraints regarding the E-VSP include no time overlap between events (e.g. charging and service trips) assigned to one vehicle (Rogge et al., 2018;Olsen et al., 2020); charging done only within a pre-defined time window (Rogge et al., 2018); travel time feasibility (Wang et al., 2022); and route time feasibility (Perumal et al., 2022). ...
