Temperature analysis of a custom-built electric vehicle at speeds below 30km/h

Abstract

In this paper, we examined the temperature variations of key constituents during the operational cycle of a custom-built electric vehicle (EV). The vehicle was made with a 10kW motor, a KLS7275D controller, and a lithium-ion battery. Temperature sensors were attached to the motor, controller, and battery to monitor and enable a comprehensive analysis of their thermal behaviors. Controlled 20 minute driving tests, encompassing both high and low speeds, were conducted to analyze temperature variations. Our findings reveal that the controller experienced the most significant temperature fluctuations compared to the battery and motor. These results highlight the importance of implementing effective thermal management strategies to ensure optimal driving performance and enhance the reliability of EV components.
