摘要
便携设备的电池供电在使用过程中通常需要对电池的电量进行监测,传统的设计方法大都是针对单电池供电的设备进行电量监测的。介绍了一种利用PIC单片机对监测芯片进行控制的智能双锂电池监测系统。整个系统可对双锂电池组的电压,电流,剩余工作时间等相关参数进行监测,并采用基于FT245RL芯片的USB接口通信模式,在单片机的控制下将电池信息高速、有效地传输到PC机上显示出来。
The capacity of battery in the battery-powered portable devices usually should be monitored in the process of application.The traditional design methods aimed at monitoring single battery-powered equipment.A PIC16F877 chip control BQ26500 for double monitoring Li-ion battery pack smart system was introduced in this paper.The whole system could monitor the relevant parameters such as voltage,current,remaining working hours.Under the control of microcomputer,the parameters could be displayed fast and effectively on the personal computer with USB Interface communication mode based on FT245RL chip.
