摘要
文章设计了一款以STM32微处理器为核心的铅酸蓄电池劣化程度检测系统。该系统通过给蓄电池施加1KHz的正弦信号,采用交流阻抗法精确检测蓄电池的内阻,并结合检测的电压电流,最终根据蓄电池内阻和劣化程度的对应关系给出分析结果。
This paper designed a lead-acid battery deterioration detection system based on STM32 microprocessor.The system used alternating-current impedance method to accurately detect the internal resistance of the battery by applying a sinusoidal signal of 1 KHz to the battery.Finally,combined with the detection of voltage and current,according to the relationship between the internal resistance and the deterioration degree of the battery,the analysis results were given.
