Energy Consumption Simulation and Analysis of Rear-Driven Electric Bus with Regenerative Braking

The Indonesian government plans to change the Transjakarta bus into an electric bus. Therefore, we analyze the energy consumption of rear-drive electric buses with regenerative braking to estimate the specifications of the electric motor and the batteries needed for one cycle of driving. BYD C6 and ITB electric buses will be compared using the driving cycle in the Transjakarta corridor 1 (Kota-Blok M). Transjakarta corridor 1 driving cycle data is collected several times to get varied driving cycles. The electric bus energy consumption model was created using Matlab/Simulink. The simulation is conducted by using the data bus specifications of BYD C6 and ITB. The results show that BYD C6 electric buses have more SOC battery remaining in one cycle of driving due to a larger amount of battery charge. However, ITB electric bus can recover more energy from the regenerative braking system due to the larger motor specifications.
