Considering that buses are equipped with significantly more batteries than typical electric vehicles, detecting and localizing faults at the cell level is crucial to avoid the substantial costs and environmental impact associated with replacing large battery systems.
Overall, the cell voltages in the tested buses showed small deviations. Of course, this could be due to the fact that a new bus battery system was analyzed in both cases. To monitor the changes, it will be worthwhile to repeat this study in a later stage, when the buses have driven more kilometers in 1 or 2 years. Figure 16.
The bus battery systems remained in good condition, with a maximum cell deviation of 3%, likely due to the vehicles’ newness. However, the continued monitoring of these systems will be essential, especially as the buses age and accumulate more kilometers, to ensure sustained energy efficiency.
The electric bus battery pack has a battery management system that monitors safety, voltage, and temperature of the individual cells for charge safety and balancing. The high voltage battery connector will be attached manually and only when the connector and the inlet have been sealed the charging begins.
The optimal BEB system under the nominal operation required five heterogeneous charging stations equipped with eight poles. A fleet of 91 BEBs with heterogeneous battery capacities is required to satisfy operation. Most buses (59.34%) are equipped with 100 kWh battery capacity.
Different benefits of adopting battery-electric buses (BEBs) are reported in the literature, considering their larger efficiency compared to internal combustion vehicles (ICV) , , such as reduction of oil dependency and local air pollution, and minimization of vibrations and noise.
