| Abstract: | 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. |
