Abstract: Provided is a method of estimating temperature in a device including a main printed circuit board (PCB), a protection and control module (PCM), and one or more batteries electrically connected to the PCM. The method includes sensing a temperature of the PCB, via a PCB temperature sensor and sensing a temperature of the PCM via a PCM temperature sensor. The method also includes estimating a temperature of at least one of the batteries based on (i) the temperature determined via the PCB temperature sensor and (ii) the temperature determined via the PCM temperature sensor.
