摘要
在电池管理系统中,电池状态参数监测系统是保证其正常运行的基础。针对电动车动力电池管理系统的需要,设计实现了一种基于DSPTMS320F28335芯片的动力电池状态参数监测系统。通过多次实验测试验证,该系统可以对动力电池的总电压、单体电压、总电流和多点温度进行监测和处理,其监测电路简单,成本低,精度高,具有一定的实用价值,同时在监测过程中电压和电流监测电路与动力电池通过光耦相互隔离,保障了监测过程的安全性。
In the battery management system, the parameter monitoring system of the battery state is the basis to ensure its normal operation.To meet the needs of the electric vehicle power battery management system, a parameter monitoring system of the power battery state was designed with the DSPTMS320F28335 chip. Numerous tests verified that the system could monitor the total voltage, monomer voltage, total current and multipoint temperature of the power battery.The monitoring circuit was simple, with low cost and high precision, so it had a certain practical value. In addition, the voltage and current measuring circuit was designed to isolate from the power battery via the optocouplerduring the monitoring process, which could ensure the security of the whole monitoring process.
