摘　　要：设计了以ARM处理器STM32为主控芯片,移植uC/OS-Ⅱ实时操作系统来实现任务调度的电池管理系统,包括锂电池参数采集模块、均衡模块、控制器区域网路通讯模块、充放电控制模块等。锂电池采集模块采集到各个锂电池的电压、温度、电流等参数通过CAN总线与主控芯片进行通讯。主控芯片根据采集的参数控制电池的能量均衡,保护电池安全,估算电池荷电状态并在LCD液晶显示屏显示电流、温度、电压和电池荷电状态信息。该系统能较准确估算电池荷电状态,快速实现多个电池之间的均衡,可扩展性良好。Designs a battery management system with ARM STM32 processor as the main control chip and uC/OS-Ⅱ real-time operating system for task scheduling implementation. It includes lithium battery parameter collecting module, balancing module, controller area network communication module and charge and discharge control module. The param- eters of voltage, temperature and current gathered from the lithium battery parameter collection module communicate with the main control chip through CAN bus. Based on the sampling parameters, the main control chip controls the battery energy equilibrium, protects the security of the battery, estimates the battery state of charge and displays the information of current, voltage, temperature and state of charge on LCD. The system estimates the battery state of charge accurately, achieves the balance between multiple batteries quickly and has good extensibility.
