Battery pack wireless array tracker
A wireless cell array tracker includes a daisy chain connecter and processor each supported on a circuit substrate. The circuit substrate is attached to a battery array. The daisy chain connector physically interfaces with a battery sensing module of the battery array. The processor retrieves data from the battery sensing module via the daisy chain connector, and commands wireless transmission of the data.
