基于AD7280 A的电池监测系统设计

摘要

The key power supply source of electric vehicles and hybrid electric vehicle is the battery power . The design is based on the ADI company′s AD7280 A lithium battery monitoring system that uses the daisy chain mode to monitor 12 real-time voltage current and battery charging status. Part of the hardware and software are given in this paper,they have reference value to the battery monitoring system design.%电动汽车和混合动力汽车，最关键的动力供给来源是蓄电池。笔者基于 ADI 公司AD7280 A设计了一种锂电池监控系统，采用菊花链方式对12个电池组进行实时电压电流和充电状态的监测。文章所给出的部分硬件和软件设计，对电池监测系统设计具有一定的参考价值。
