锂电池性能一致性监测装置

Performance consistency monitoring device of lithium battery

为保证便携设备的正常使用,有必要对其内置锂电池进行实时监控。基于DS2438电池监测芯片开发的锂电池监控装置能实现锂电池状态实时监测,状态异常时通过蜂鸣器自动报警。该装置通过STM32微控制器控制DS2438电池管理芯片及其相应的外围电路,实现对锂电池温度、电流、电压及剩余容量的测量,能将数据通过串口通信传输到PC机。

In order to ensure the normal use of portable devices,it is necessary to monitor the lithium battery in real time.The real-time monitoring of lithium battery status could be realized through the lithium battery monitoring device developed based on DS2438 battery monitoring chip,and the buzzer would automatically alarm when the status was abnormal.The DS2438 battery management chip and its corresponding peripheral circuit were controlled by the device through STM32 microcontroller.The measurement of temperature,current,voltage and residual capacity of lithium battery was realized,and the data was transmitted to PC through serial port communication.
