According to the lithium battery in the application of disaster emergency rescue cabin, this paper designs a monitor- ing system of battery remaining capacity based on DS2438 smart battery monitoring chip which consists of a control module, mea- surement module and communication module. ATmegal6 single-chip microcomputer is the key cell of control module, which imple- ments read/write control to DS2438 and serial communication. Measurement module implements the collection of battery remaining capacity. RS232 is choosed in communication module to communicate with PC. Experimental results show that the system works well on monitoring the remaining capacity of lithium battery in real time with high stability and strong expansibility, which provides battery information to the disaster emergency rescue cabin system.
