Abstract: The temperature of the electric vehicle is one of the most impotant factors influencing the batteries’ SOC and its service life.In order to measuring the temperature exactly and realiablely,this article uses DS18B20,which is a digital temperature sensor made in the United States Dallas Semiconductor Corporation,to make design of the muti-point temperature measurement.As a kind of the 1-wire bus devices,several DS18B20 can be connected to one data line,significantly saving the port resources of the MCU.
