基于STM32的低功耗无线电池监测系统设计

针对目前起动电池、小型设备的电池及其他零散使用的电池的状态监测困难问题,文中将集成了低功耗单片机、A/D采集模块、RFID通信模块及低频唤醒模块的监测电路板封装到电池上,借鉴汽车PKE无钥匙系统低频唤醒的理念,设计了一款基于STM32单片机的低功耗无线电池监测系统。该系统利用RFID技术免接触、远距离、批量读取电池状态信息,并借鉴汽车PKE系统远距离低功耗唤醒的优势,依托STM32L151低功耗单片机,实现了零散分布的蓄电池管理的智能化、高效化。

Design of Low Power Wireless Battery Monitoring System Based on STM32

Aiming at the problem of current status monitoring of starter batteries,small equipment batteries,and other scattered batteries,the monitoring circuit board integrating low-power microcontrollers,A/D acquisition modules,RFID communication modules,and low-frequency wake-up modules is packaged in the battery.Based on the concept of low-frequency wake-up of the car PKE keyless system,a low-power wireless battery monitoring system based on the STM32 microcontroller is designed.The system adopts RFID technology to read contactless,long-distance,and batch-read battery status information,and draws on the advantages of long-range low-power wake-up of the automotive PKE system.Relying on the STM32L151 low-power single-chip microcomputer,it realizes the intelligent and high-efficient management of scattered distribution of battery.
