Abstract

The electrification of urban public transportation has become a key strategy for reducing energy consumption and greenhouse gas emissions while improving overall system efficiency. This study develops a comprehensive modeling framework to evaluate the energy consumption and charging infrastructure requirements of electric bus fleets operating in urban environments, incorporating key operational parameters such as travel distance (126 km/day), vehicle energy efficiency (1.2–1.5 kWh/km), fleet size (5–30 buses), and regenerative braking efficiency (25%). The results indicate that a single electric bus consumes approximately 151.2 kWh/day under typical operating conditions, which can be reduced to 113.4 kWh/day through regenerative braking, representing a 25% improvement. At the fleet level, electricity demand increases proportionally, reaching 0.76 MWh/day (5 buses), 1.51 MWh/day (10 buses), 2.27 MWh/day (15 buses), and 3.02 MWh/day (20 buses). Furthermore, fast-charging systems with a capacity of 150 kW can deliver up to 300 kWh within 2 hours but may introduce peak load demands of up to 0.75 MW. These findings highlight the importance of integrated energy modeling, smart charging strategies, and grid-aware planning

Abstract

Purpose - This study aims to develop a spatio-temporal load characterization framework for electrified two-wheeler mobility and evaluate the potential implications of charging demand on urban distribution networks under varying operational scenarios. Design/methodology/approach - The framework integrates mobility behavior, energy consumption, and charging demand using key parameters, including travel distance (40–80 km/day), energy consumption rate (0.04–0.06 kWh/km), and fleet size (100–1000 units). Findings - Results show that individual energy demand ranges from 1.6 to 4.8 kWh/day per vehicle, while aggregated demand increases proportionally, reaching approximately 0.16 MWh/day, 0.80 MWh/day, and 1.60 MWh/day for fleets of 100, 500, and 1000 units, respectively. Charging demand is highly concentrated during evening periods, creating synchronized load peaks and localized stress on distribution infrastructure. Research implications/limitations - The study is limited to simulated mobility and charging scenarios; however, it provides a practical framework for assessing the impacts of electric two-wheeler adoption on urban power distribution systems. Originality/value - This research offers an integrated spatio-temporal approach combining mobility patterns, energy consumption, and charging behavior within a unified framework, providing valuable insights for coordinated charging strategies, load balancing, and infrastructure planning.
