%X With the rapid development of the automotive industry, how to save energy and reduce emissions has also become a concern. New electric vehicles have become the key to solving the problem. As the core component of electric vehicles, lithium batteries have an important role in their service life and operating conditions for the mileage and performance of electric vehicles. Therefore, in order to ensure the safe and effective operation of electric vehicles, it is of great significance for the research of electric vehicle lithium battery parameter detection system. Based on this direction, this subject designs an electric vehicle lithium battery parameter detection system with STM32f103RBT6 microcontroller as the control core, as the main control processor, combined with temperature detection module, voltage detection module, current detection module, buzzer alarm module and display module. This article mainly completes the system design from both hardware and software aspects. It uses detection voltage and current modules to detect the lithium battery of electric vehicles in real time. At the same time, it uses an OLED display module to display the status data of the lithium battery in real time, and an alarm module is set to complete the alarm function. The experimental results show that the electric vehicle lithium battery parameter detection system designed in this paper is stable and reliable. The system can measure parameters such as battery current, voltage and temperature in an analog state.
