摘要
利用MSP430单片机,设计了一种简易的汽车蓄电池电压监视器。利用MSP430提供的内部ADC,对蓄电池工作状态,特别是起动瞬间的电压信号进行采集,绘制瞬时电压波动曲线,并以此曲线作为参考,分析蓄电池工作状态。实测结果表明,通过本文提出的方法,可以实现蓄电池失效的预警。
A simple vehicle battery voltage monitor is designed based on the microcontroller MSP430. The working state of the battery, especially the voltage signals when starting can be acquired according to the internal ADC provided by MSP430. The transient voltage fluctuation curves can be drawn as the reference for battery working state analysis. The test result shows the prewarning of battery invalidation can be realized by this method.
