Research on the Influence of Different Working Conditions on the
Driving Range, Energy Consumption and Emissions of Heavy-Duty Hybrid
Buses 2023-01-7035
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.
