Abstract:
By analyzing different kinds of the reported voltage measuring methods for the battery voltage,two key technologies have been proposed for developing the battery online monitor equipment in this paper.Firstly,INA148 differential amplifier chip is suggested to make up the linear sampling circuit,which has such advantages as low cost,high precision and high common mode resistive ratio,and the ARM(STM32F103ZE)is employed as the lower level core microprocessor to make a tour collecting the voltage and temperature parameters of N lines single battery.Secondly,the RS484 is adopted as the serial communication interface to realize the long distance communication between single-chip microcomputers and host computer,by processing the collected data and transferring them to the host computer,and the logic analyzer is further utilized to offer the accurate technique parameters for online monitoring all batteries and fast diagnosing the failure ones.The above proposed two key techniques have been successfully applied in newly-developed battery online monitor equipment,which has been adopted by Xu-tang power plant,etc.
