1. An energy storage device monitoring system for adjusting a timing of measurements of a plurality of energy storage devices, the system comprising:
a plurality of energy storage device monitoring circuits configured to receive a first signal that, in corresponding ones of the energy storage device monitoring circuits, initiates: 1) an analog-to-digital conversion that represents a voltage of at least one of the plurality of energy storage devices, and 2) a counter that represents a local clock source of the corresponding energy storage device monitoring circuit;
a designated first one of the energy storage device monitoring circuits configured to:
intermittently receive a second signal; and
modify the second signal to include information representing the counter of the designated first one of the energy storage device monitoring circuits; and
transmit the modified second signal to a second energy storage device monitoring circuit; and
the second energy storage device monitoring circuit configured to:
determine a difference between the information representing the counter of the designated first one of the energy storage device monitoring circuits and information representing the counter of the second energy storage device monitoring circuit; and
in response to the determined difference, adjust the local clock source in the second energy storage device monitoring circuit.
