摘　　要：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。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.
