Abstract
A method for accurately measuring a battery temperature using a temperature sensor embodied in a battery monitoring integrated circuit is disclosed. The method includes performing calibration to estimate a thermal resistance between the battery monitoring integrated circuit and a terminal of a battery, measuring a temperature using the temperature sensor, measuring a voltage at the terminal or at a supply pin of the battery monitoring integrated circuit while a current is being used to charge or discharge the battery, calculating a power by multiplying the voltage and the current, and calculating a self-heating temperature adjustment to the temperature by multiplying the power and the thermal resistance.
