Abstract
With the increasing global focus on environmental protection and energy efficiency, the development and application of electric vehicles as an alternative to traditional fuel vehicles have attracted wide attention. As the core component of electric vehicle, the stability and reliability of electric vehicle drive motor are directly related to the overall performance of electric vehicle. Therefore, the thermal management of Emotors has become an important topic in the field of electric vehicle technology. This paper outlines the importance of thermal management of EV drive motors. The electric vehicle drive motor will produce a large amount of heat in the process of working. If the heat cannot be dispersed in time, it will lead to the increase of the motor temperature, and then affect the performance, life and safety of the motor. Therefore, the key to ensure the effective thermal management of electric vehicles to ensure their operation within the appropriate temperature range is to ensure the performance and safety of electric vehicles. This paper discusses the technical method of thermal management of electric vehicle drive motor in detail. These methods include air cooling, liquid cooling, heat pipe cooling and many other ways. Among them, air cooling has the advantages of simple structure and low cost, but the heat dissipation effect is relatively limited; liquid cooling has good heat dissipation effect and accurate temperature control, but high system complexity; heat pipe cooling combines the advantages of air cooling and liquid cooling, and has the characteristics of high efficiency and reliability. This paper also analyzes the applicable scenarios and advantages and disadvantages of various cooling methods, which provides a reference for the design of the thermal management scheme of electric vehicle drive motors. This paper also introduces the control strategy of electric vehicle drive motor thermal management. These strategies include closed-loop control based on temperature sensors, predictive control based on thermal model, etc. By monitoring the motor temperature in real time, and adjusting the operating parameters of the cooling system according to the temperature change, the accurate control of the motor temperature can be realized, and the efficiency and reliability of thermal management can be improved. This paper summarizes the current situation and future development trend of thermal management of Emotors. At present, the thermal management technology of electric vehicle drive motor has made some achievements, but there are still many challenges and problems. In the future, with the continuous development and improvement of electric vehicle technology, the thermal management technology of electric vehicle drive motor will continue to innovate and progress, to provide more powerful support for the popularization and development of electric vehicles.
