Efficiency Analysis of Regenerative Braking System in BYD K9 Electric Bus on Transjakarta Route 1E
Keywords:
Electric Bus, Regenerative Braking, Energy Efficiency, BYD K9, TransjakartaAbstract
This study aims to evaluate the recovery efficiency of the regenerative braking system in BYD K9 electric buses operating on Transjakarta route 1E. The method used is a quantitative experimental approach through direct observation of the vehicle dashboard. Data were collected from three bus units representing the highest, lowest, and average energy consumption. The analysis reveals that energy recovery efficiency ranges from 36.62% to 50.27%, influenced by speed, road gradient, and driver behavior. These findings highlight the significant contribution of regenerative braking systems in reducing energy consumption and extending electric bus operational range.
