1. A method comprising:
determining, via at least one temperature sensor, a temperature of a first portion of a device during a charging process of a power source of the device;
estimating, by processing circuitry and using an algorithm that incorporates the temperature of the first portion of the device, a temperature of a second portion of the device, wherein the algorithm is representative of an estimated temperature difference between the first portion of the device and the second portion of the device according to at least a dynamic transfer function that operates in a time-domain, and wherein the dynamic transfer function is implemented using a first order low-pass filter; and
controlling, by the processing circuitry and based on the temperature of the second portion of the device, charging of the power source.
