摘要
在分析比较几种常见蓄电池剩余电量检测方法的基础上,介绍了利用MSP430单片机设计车辆蓄电池报警器的工作要点。该报警器实现了特定条件下蓄电池剩余电量指示,蓄电池内阻大报警,充电电压过高报警,非规范启动(单次起动时间超过5s、两次启动间隔时间少于15s、连续启动次数超过3次)发动机提示报警等功能,具有实用价值。
This paper analyse and compare of several common battery residual capacity measurement method, and describe approach to design vehicle battery alarm using MSP430 MCU. The alarm under certain conditions to achieve the battery residual capacity imtructions, battery internal resistance of large alarm, alarm charging voltage is too high, non-normative Start （single start-up time more than five seconds, two to start interval time of less than 15 seconds, to start the number of consecutive more than three times） Engine prompted alarm and other functions, has practical value.
