Summary:

Research on the energy consumption and emission of heavy-duty hybrid electric buses was carried out based on the chassis dynamometer. The effects of different working conditions on the driving range, electric power, energy consumption and emissions were analyzed. The testing process included three phases, the pure electric driving range phase, energy adjustment phase and electrical energy balance phase. The testing cycle includes CHTC-B (China Heavy-duty commercial vehicle Test Cycle for Bus) and CCBC (Chinese typical City Bus Cycle). The energy consumption and emissions were measured simultaneously during the test. The results show that the driving range of CHTC-B method is less than that of constant velocity method and the power consumption of CHTC-B method is higher than that of constant velocity method. The energy consumption of CHTC-B is 20% higher than that of CCBC. Comparing the emissions after the engine is warmed up, it can be concluded that the CCBC pollutant has a higher probability of exceeding the China 6 limit than CHTC-B condition
