摘要
设计一种基于内阻法监测蓄电池剩余电量的系统,首先通过单片机驱动内部AD模块来采样蓄电池上的开路电压和短路电流,然后计算得出蓄电池的剩余电量,并将结果显示在液晶显示器上。将电池的各种参数存入单片机内部的EEPROM存储器中,使用单片机内部的FLASH来模拟EEPROM可以最大限度地节省硬件成本。
The design of a system of surplus electricity resistance monitoring battery based, first through the microcontroller drive internal AD module to sample the open circuit voltage and short circuit current on the battery,then calculated the residual capacity of battery,and the results are displayed on the LCD monitor.The various parameters of the battery into the microcontroller's internal EEPROM memory,the use of the microcontroller inside the FLASH to simulate the EEPROM can maximize the cost savings.
