Abstract: In one example, a method includes determining, by a device, a plurality of voltage values that each correspond to a respective voltage drop across a remote p-n junction while the remote p-n junction is biased at different respective current levels, wherein each of the plurality of voltage values is a function of at least: one of the different respective current levels, a temperature of the remote p-n junction, and a series resistance between the device and the remote p-n junction. In this example, the method also includes, determining, by the device, an intermediate value based on a difference between at least three voltage values of the plurality of voltage values, wherein the intermediate value is not a function of the series resistance, and determining the temperature of the remote p-n junction based on the intermediate value such that the temperature is not a function of the series resistance.

Abstract: Devices, systems, and methods for battery monitoring are disclosed. An example method performs a first measurement on a battery cell installed in a location to determine a first charging capacity and determines a set of values for a permitted charging capacity trace region based on the first charging capacity and a number of charge/discharge cycles subsequent to performing the first measurement. The example method performs a second measurement on a battery cell installed in the location to determine a second charging capacity and compares the second charging capacity to the permitted charging capacity trace region and determines that the battery cell installed in the location at a time of the second measurement is not the same battery cell installed in the location at the time of the first measurement when the second charging capacity is not a value within the set of permitted values of the charging capacity trace region.

Abstract: In one embodiment, a method includes receiving power at a power consumer device coupled to a power provider device by a cable. The received power is supplied at a first current at an input of the power consumer device and is supplied to a load in the power consumer device. The method includes measuring a rate of change of the voltage at the input of the power consumer device, and determining whether the rate of change of the voltage at the input of the power consumer device is less than a first target rate of change of voltage. The current received at the input of the power consumer device is reduced to a second current lower than the first current if the rate of change of the voltage at the input of the power consumer device is greater than the first target rate of change of voltage.
