摘要
论文提出了一种针对串联电池组电压测量的新的硬件电路。该方法将电池组中各单体电池从不同电压等级变换到同一电压范围0￣5V,使得电池管理系统可以通过一片多路A/D采样芯片或者带多路的A/D转换通道的单片机,来实现对多节锂电池的电压精确检测,并通过仿真和放电实验进行了验证,电路新颖、实用性强,降低了成本。
This paper presents a new measuring method for a serial Li-ion battery. This method transforms different voltage range of the serial battery into a same range of 0-5V. Thus, the voltage can be measured with a single multiplex A/D chip Simulation and experimental results are also given.
