A Safety Protection Circuit for Mine-used Series Batteries

In this paper, it designed a safety protection circuit for rechargeable series batteries based on microcontroller, and described the hardware and software design of this protection circuit. The safety protection circuit could reliably cut off the series batteries connection with external circuit when overcharge, over-discharge, over temperature of a single battery or series batteries occurred. So it could ensure the safety of the battery, and prolong the service life of the battery.
