Incorporating in-motion charging into Battery Electric Bus (BEB) transit systems offers a practical approach to overcoming key challenges of stationary charging, including limited resources, long charging times, and higher battery costs. This study introduces a comprehensive optimization framework that combines conductive Overhead Catenary Charging (OCC) technology with overnight depot charging to minimize overall BEB system costs, both capital and operational. Capital costs are effectively reduced by strategically determining the optimal placement of OCC segments, battery capacity, and depot charging configurations. Simultaneously, operational costs are optimized through refined charging schedules that account for electricity time-of-use (ToU) pricing, greenhouse gas (GHG) emissions intensity (measured in tCo2e), and BEB battery degradation costs. _x000D_
Applying this optimization framework to a real-world transit network reveals significant findings, including a 56% reduction in peak electricity demand, a 13% drop in GHG emissions, and a 27% decrease in overall charging costs. Furthermore, sensitivity analysis underscores the influence of OCC infrastructure costs on total system costs while increasing OCC charging power further enhances cost savings by up to 28%.
