Calculation and simulation of the energy consumption of lithium battery driven electric buses

Abstract

There aremany different driving cycles commonly used in regions and around the world; however, each manufacturer usually only publishes the vehicle's operating indexes according to a certain driving cycle, especially for electric vehicles. In addition, the method for determining the capacity of the electric power source has not been clearly stated. Therefore, this article presents the research results on the method for calculating the capacity of the battery system on an electric bus when simulating a common driving cycle and arranging the battery system for the bus according to the standard configuration 6S86P (86 battery cells connected in parallel into a set and a module with 6 sets of battery cells). From there, simulate the basic operating parameters of the battery system on an electric bus using software. The results of the article provide a scientific basis for readers to refer to in calculating the capacity of the energy source and the method of arranging the battery system according to the standard configuration for electric cars as well as other pure electric vehicles. The research results can also be used for manufacturers (buses, traditional coaches) to refer to in switching to producing electric buses.
