一种新型的干电池放电特性测量仪

摘要

用STM32‐cortex‐m3单片机作为干电池放电特性测试仪检测电路的核心，存储芯片24CO2和W25X16完成终止电压门限值的存储和采集到的数据长度的存储，能实现长达145h的数据记录。主要由电池检测模块、继电器ULN2803驱动模块、大小容量存储模块和液晶显示模块组成，测量模式采用按键选择，完成对干电池放电数据的采集处理和终止电压值的预设。能够很好地实现电压电流值的采集、存储和显示。%Using STM32‐cortex‐m3 as the core of the testing circuit of the discharge characteristics of the dry battery .Memory chip 24CO2 and W25X16 to complete the storage of the termination voltage threshold and the storage of the data acquisition ,it can achieve up to 145 hours of data records .It is made mainly by battery detection module ,relay ULN2803 driver module ,different size capacity storage module and LCD module .The measurement mode using the key to select and completion of the collection and processing of dry battery discharge data and the termination of the voltage value of the default .It can be very good to achieve the collection ,storage and display of voltage current value .
