摘要
为提高电池组的使用寿命,设计了一种基于S32K的电池管理系统主控单元。该设计对绝缘检测系统进行了改进,提出了绝缘监控系统与绝缘检测系统相配合的绝缘监测系统,对系统的绝缘状态进行实时监测,有助于避免故障的发生;同时,对SOC估算方法进行了改进,提高了估算精度。实验表明:所设计的主控单元运行稳定,能够实时、准确地完成电流以及总电压的采集、SOC估算、实时通讯、绝缘检测等功能,保证了电池组的安全稳定运行,提高了电池组的使用寿命。
To improve the service life of battery pack,a main control unit of battery management system based on S32K is designed,which is used to improve the insulation detection system.This paper puts forward the insulation monitoring system which is used with the insulation detection system.Real-time monitoring of the insulation state of the system is done,thus avoiding the occurrence of faults.At the same time,the SOC estimation method is improved to improve the estimation accuracy.Experiments show that the designed main control unit runs stably and can be used to accurately complete the data acquisition of current and total voltage,SOC estimation,real-time communication,insulation detection and so on.It ensures the safe and stable operation of the battery pack and improves its service life.
