Abstract: Since Electric Auxiliary Systems (EAS) accounts for a large proportion of electric bus energy consumption, in order to reduce EAS energy consumption and improve bus driving range, the working principles of EAS have been studied. The number of passengers, bus interior and exterior temperature can have great influence on EAS energy consumption, it is important to dynamically manage EAS working status according to the changes of bus driving conditions for saving energy, then an integrated control method for EAS is proposed for better meeting the real demands of EAS. The proposed method takes EAS as a whole and can manage EAS working status mainly according to the changes of bus passengers. For verifying the effectiveness of the proposed method, an electric bus model including EAS has been built and simulated by co-simulation in different platforms. Compared with common control method, the experimental simulation results shows that EAS energy consumption can be effectively reduced by dynamically managing EAS working status according to the changes of bus driving conditions, energy consumption proportion of each subsystem in EAS also has been discussed. The proposed method gives new way for saving EAS energy and has great application value for electric buses. [ABSTRACT FROM AUTHOR]
