Power Requirement and Cost Analysis of Electric Bus using Simulation Method with RCAVe-EV1 Software and GPS Data; A Case Study of Greater Jakarta

Electric vehicles’ power requirement and cost analysis require consideration in terms of their usage load and mileage. It is due to the unique character of the charging energy compared to internal combustion vehicles. The motor capacity and mileage will affect the vehicle's weight, especially the battery. If the battery is excessively big, it will affect passenger space. In comparison, buses with diesel engines are generally designed for long distances and rough roads. If used in the city, with relatively gentle road types, the engine will tend to be over-specification. This research aims to design the bus power requirements according to road conditions. The method is theoretical and simulated with specific GPS data. In this case, the bus power is designed for the city's needs, with a case study of battery electric buses (BEBs) for the route of the city of Jakarta and its surroundings, namely Bogor, Depok, Tangerang, and Bekasi. In addition, an economic study will also be a part of this research. Bus companies need this study to decide on the procurement and use of an electric bus fleet. The simulation results show that the power and battery capacity of inner-city buses need not be as large as inter-city buses. A bus with a motor power rating of 100 kW and batteries with a total of 200 kWh is very appropriate to carry 85 passengers over a distance of 200 km on one charge. Moreover, with proper incentives from the government, the price of electric inner-city buses is very competitive. It has the advantage of having a service life of more than ten years.
