【摘要】 针对新能源电动汽车提出了一套完整的电池管理系统方案,采用STM32芯片作为主控芯片并架构嵌入式操作系统Free RTOS,由嵌入式操作系统实时监控充电、放电的过程,并且在LCD显示屏上实时显示锂电池组的工作状态。设计信号采集电路采集主控板上的总电压、电流和子模块上的单体电压、温度等参数,为锂电池管理系统提供最原始的数据。该智能模块兼有报警和散热装置,提高了系统的安全性。更多还原

【Abstract】 This paper proposes a complete scheme of battery management system for new-energy electric vehicles. This scheme adopts STM32 chip as the master chip and set up embedded operating system Free RTOS. The charge and discharge processes are monitored in real time by the embedded operating system, and the operating status of lithium battery pack is displayed in real time on LCD screen. The parameters are set, including total voltage and current of the control board, and the cell voltage and temperature of submodule, to provide the raw data for lithium battery management system. This smart module has alarm and cooling devices to improve the security of system.更多还原
