Abstract

The invention relates to the technical field of electronics, particularly to a battery temperature measurement method. The battery temperature measurement method comprises the following steps of, firstly, providing a thermistor arranged inside the power supply battery of a mobile terminal to sense the temperature of the power supply battery and converting the temperature into an electric signal for output; secondly, performing analog-digital conversion on the electrical signal to obtain the voltage value of the electrical signal; thirdly, converting the voltage value into resistance value; fourthly, according to the resistance value, searching from a resistance-temperature corresponding relation table to obtain a corresponding temperature value. The battery temperature measurement method converts the thermistor sensed value into the resistance value and then obtains the current temperature of the power supply battery from the resistance-temperature corresponding relation table according to the resistance value, thereby simplifying configuration process and facilitating temperature measurement.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a battery temperature measurement system and method. Background technique [0002] The detection of battery temperature is very important for smart phones, because the battery temperature will change with the operation of the system, too high temperature will have certain safety hazards, and the use of the battery itself must be within a certain temperature range Inside. In order to be able to detect the temperature of the battery, a thermistor is usually built in the lithium battery in the prior art, and a detection pin is provided externally. The data acquisition channel of the system reads the voltage value of the detection pin through a certain circuit connection, through Establish a table corresponding to voltage-temperature, and look up the voltage-temperature table from the voltage value to obtain the actual temperature value; the disadvantage of this method is: since...
