ABSTRACT
With the rapid development of the electric vehicle industry, the safe management and efficient utilization of batteries are of great significance for improving vehicle range and ensuring driving safety. Traditional battery management methods have problems such as single monitoring parameters, delayed data feedback, and lack of remote monitoring, making it difficult to meet the needs of intelligent management of electric vehicles.
The electric vehicle battery management system based on the STM32F103C8T6 microcontroller integrates DS18B20 temperature sensor, INA219 voltage and current detection module, OLED display, and AIR780 4G module, realizing comprehensive monitoring and remote management of electric vehicle battery status. The core functions of the system include: real-time detection of battery temperature through DS18B20, triggering an early warning when the temperature exceeds the safe range; accurate collection of battery voltage and current by means of the INA219 module to calculate the remaining power and estimated driving range; real-time display of key data such as temperature, voltage, current, power, and range through the OLED display, facilitating users to intuitively understand the battery status; remote transmission of monitoring data to the mobile phone terminal using the AIR780 4G module, enabling real-time monitoring of battery status and abnormal alarms.
The implementation of this system effectively improves the intelligent level of electric vehicle battery management, provides users with comprehensive and timely battery status information, ensures the safe use and efficient utilization of batteries, and also provides a reference for the research and development of similar electric vehicle battery management equipment, with high practical application value.
