1. A system of detecting a change in a battery cell, comprising:
an embedded controller:
a touch pad in communication with the embedded controller;
a battery assembly, the battery assembly including:
at least one battery cell;
a swell detection circuitry adjacent to the battery cell;
the swell detection circuitry including:
a substrate with a first set of electrodes in communication with the embedded controller;
memory in communication with the embedded controller and storing programmed instruction that, when executed, cause the processor to:
determine a baseline profile of a battery cell with a capacitance sensor;
detect a changed profile from the baseline profile with the capacitance sensor;
match the changed profile with a stored profile where the stored profile is associated with a condition; and
classify the battery cell as having the condition associated with the stored profile;
the touch pad including:
a second set of electrodes of the touch pad are electrically isolated and spaced apart on the substrate from the first set of electrodes of the battery swell detection circuitry;
wherein the embedded controller is configured to process the outputs from the battery swell detection circuitry and process the touch inputs from the touch pad.
