Features of development of the mathematical model of the electric motorcycle thermal regulation system

Abstract

BACKGROUND: Use of thermal regulation systems is necessary to maintain the required temperature range of electrical components of electric vehicle. Even at the design stage of the vehicle, the being developed mathematical model of the thermal regulation system helps to determine the necessary parameters of the thermal regulation system, to select algorithms for controlling the system and to calibrate the developed algorithm to ensure the necessary heat removal from electrical components.

AIM: Development of a mathematical model of the thermal regulation system of an electric motorcycle, aimed at determining the potential capabilities of optimizing the system by controlling the air flow through the radiator.

METHODS: The mathematical model is built in the AVL Cruise software environment. The properties of the components included in the model were obtained as a result of laboratory studies and supplemented with the equilibrium equations of power at the inputs and outputs taking into account their efficiency.

RESULTS: Using the developed model of the radiator of the thermal regulation system, the temperature graphs of the electric motor and the inverter of the electric motorcycle during the driving cycle were obtained. It is noted that the applied thermal regulation system is capable of maintaining the temperature of electric components in the specified range.

CONCLUSIONS: The mathematical model of the radiator of the thermal regulation system proposed in this paper makes it possible to carry out calculations of the system at the stage of design of electric vehicles. In addition, the model has a potential for further development aimed to fuller determination of the parameters of the thermal regulation system, including the thermal efficiency.
