摘要
介绍一个以51系列单片机为主控单元的串联锂离子电池组监测系统。采用差分放大器和模拟开关轮流检测单体电池电压,利用单片机的IO接口和DS18B20实现单总线多点温度检测。系统简单经济,经过试验,能可靠、准确地对串联锂离子电池组进行监测。
A supervising and measuring system of serial lithium-ion batteries which base on MCS51 series microcontrollers is introduced.The system measures the voltage of serial lithium-ion batteries by using differential amplifier and analog multiplexers.A one-wire bus measuring system with MCS51 and DS18B20 has been developed for the system of serial lithium-ion batteries.The system is simple and cheap.Tests show that the system is capable of reliable and accurate supervision and measurement of serial lithium-ion batteries.
