摘要:
为克服传统的电池管理系统(battery management system, BMS)开发方法不仅不利于先进算法的软件实现,且存在开发周期长和费用高的缺点,基于MCS D2P快速控制原型开发平台搭建BMS硬件,针对动力锂电池由多节电芯串联而成的特点,分析BMS对电池组总电压、电流、电芯电压和温度的实时测量,对电池剩余电量实时评价的功能,以及由主控模块、检测模块和均衡管理模块构成的主要硬件结构.设计主控软件数据流、主程序流程图、数据采集程序流程图和荷电状态(state of charge,SOC)估算程序流程图.以由15节电芯构成的48 V、50 Ah磷酸铁锂电池组为试验对象,设计周期性充放电测试试验,得到电池总电压和电流的测量误差均小于±0.5%,温度的测量误差小于±0.5 ℃,SOC实测值与理论值差值小于8%,验证了主控软件设计的可行性.
Abstract:
The traditional battery management system (BMS) development method not only is bad against the advanced algorithm implemented by software, but also has a lone development cycle and high development cost. To overcome these problems, based on the MCS D2P rapid control prototype development platform, the BMS hardware is built. The power lithium battery is made up of a multi battery cell in series. In view of this characteristic, the BMS real-time measurements of battery voltage, current, cell voltage and temperature are analyzed, the BMS real-time evaluation of battery residual power is analyzed, and the main hardware structure composed of main control module, detection module and equalization management module is analyzed. On this basis, the data flow of master control software, the main program flow chart, the data acquisition program flow chart, the state of charge (SOC) estimation program flow chart are designed. Taking a 48 V/50 Ah lithium iron phosphate battery pack consisting of 15 cells as the test object, the periodic charging and discharging test is designed. The test results show that the measurement error of the battery total voltage and current is less than ±0.5%, the measurement error of the temperature is less than ±0.5 ℃, the difference between the SOC measured value and the SOC theoretical value is also within 8%. So the feasibility and the correctness of the master control software design are verified.
