摘　　要：磷酸铁锂电池作为一种新型的锂离子蓄电池,具有高容量、高输出电压、良好的充放电特性,但也存在着电池组一致性、电池过充等问题,因此在实际使用中需要配合电池管理系统(BMS)对其进行管理和保护,以发挥其最佳性能。文中设计了一款具有24 V/20 A输出功能的磷酸铁锂电池电源管理系统,利用模块化的设计理念,采用MAX17830的硬件架构对电池组进行数据的采集,并使用RT-Theart嵌入式操作系统进行任务管理。其主要研究内容是磷酸铁锂电池管理系统的软件设计及系统平台测试。Lithium iron phosphate battery is a new type of lithium ion battery with high capacity, high output voltage, good charge and discharge characteristics. But there are also problems such as consistency of battery pack and overcharge of battery, therefore the battery management system （BMS） can be used in practical in order to manage and protect the battery. In this paper a battery management system for lithium iron phosphate battery with 24 V/20 A output function is designed, the modular design concept is used. Using the MAX17830 hardware architecture to collect data of the battery pack and using RT-Theart embedded operating system to manage the task. The main content of this paper is the software design and system platform test of lithium iron phosphate battery management system.
