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: A circuit includes a first analog to digital converter configured to convert an analog voltage sample of a rechargeable power source into a digital voltage value, a second analog to digital converter configured to convert an analog current sample of the rechargeable power source into a digital current value, a charge state controller configured to determine a charge state of the rechargeable power source based on the digital voltage value and the digital current value, and a communication interface configured to output a computer-readable indication of the charge state. The charge state controller is further configured to receive pregenerated voltage values and pregenerated current values, and determine a simulated charge state of the rechargeable power source based on the pregenerated voltage values and the pregenerated current values. The communication interface is further configured to output a computer-readable indication of the simulated charge state.

Abstract: According to various aspects, a controller may be configured to: control a transmission over a single-wire interface of an instruction corresponding to a high-current operation; and control an electrical behavior of a charging path to provide current at the single-wire interface during a time period corresponding to an execution of the instructed high-current operation.
