嵌入式动力锂离子电池使用状态记录与报警器的研制

Embedded power lithium-ion batteries use state records and the development of alarm

采用PIC18F2420纳瓦技术微处理器,SD卡作为数据存储单元,研制了一种动力锂离子电池使用状态记录与报警器。可以嵌入到动力锂离子电池安装盒小于3cm×2.5cm×0.6cm的微小空间内。实时检测电池的充放电过程数据,按照时间顺序记录到SD卡中。根据采样到的电流、电压值判断出动力锂离子电池过充电或过放电时,通过显示报警电路发出声光报警信号。从而防止动力锂离子电池因不当使用导致的寿命缩短或永久失效,甚至可能出现的安全问题。

using the technology PIC18F2420 nanoWatt microcontroller,SD card as data storage unit,developed a lithium-ion battery power to use state records and alarm.Can be embedded into the power lithium-ion battery installed box is less than 3cm × 2.5cm × 0.6cm small space.Real-time detection of battery charge and discharge process data,according to the order recorded in SD card.According to the sampled current and voltage values to determine a power lithium-ion battery over charge or over discharge,through the circuit to issue an alarm sound and light alarm signal.In order to prevent power lithium-ion batteries due to shortened life expectancy caused by improper use or permanent failure,and even security problems that may arise
