ABSTRACT
Electrification of city buses, which play a major role in public transportation, is imperative for efficient use of limited resources and reducing adverse effects of fossil fuels on the environment. One of the vital processes in electrification projects in the automotive industry is testing. The main target of testing is to achieve a reliable and reproducible test that simulates real-world driving conditions to disclosure any weakness of the product at the early stage of the life cycle. Other side targets of testing are to achieve the main target with low cost and environmentally friendly testing. In this study, results of research and development in accelerated life test stand for a mild hybrid system is described. The realized test stand serves to product reliability by enabling life tests with in excess of its normal service parameters real-world driving conditions such as revolution, electrical power, high ambient temperature, cooling effect, and rest-bus CAN simulation. By using temperature as a stress factor for the mild hybrid powertrain under test, life test duration was shortened 4.65 times according to the Arrhenius equation. Thanks to the realized test stand, the mild hybrid life test was achieved by decreasing time and cost.
Key Words: Electrification of buses, Hybrid electric powertrain, Accelerated life test, Arrhenius equation
