The increasing use of electric vehicles as a sustainable transportation solution also encourages their integration into public transportation systems, such as those implemented by PT Transportasi Jakarta. One important aspect of electric bus operations is the efficiency of power consumption and the effectiveness of battery charging. This study aims to analyze the percentage decline in State of Charge (SoC), energy efficiency (kWh/km), and battery charging characteristics of the Zhongtong Medium Low Entry electric bus operating on Transjakarta routes under two operational conditions: without passengers and with passengers. The method used involved direct observation and field data recording over four testing periods, covering energy consumption, distance traveled, and charging capacity, with tests conducted under both operational conditions. The results show that the presence of passengers causes an average SoC decrease of 17% compared to the condition without passengers, and an increase in energy consumption of 43%, from 0.27 kWh/km to 0.70 kWh/km. The incoming electrical power during charging exhibited greater variation under the passenger-loaded condition; however, the average difference was only about 2%, indicating a relatively small impact on the battery charging process. These findings confirm that the additional passenger load significantly affects energy consumption efficiency and SoC levels of electric vehicles but has minimal influence on charging power. This study provides important contributions to energy management and the development of battery charging infrastructure for electric buses to support more efficient and sustainable operations.
