1. A method of synchronous monitoring for a battery management system, wherein the battery management system comprises a battery pack having a plurality of batteries coupled in series, the method comprising:
a) obtaining first and second measurement results representing a state parameter of a battery at a same time, wherein the obtaining the first and second measurement results comprises simultaneously obtaining a first sampling signal representing the first measurement result, and a second sampling signal representing the second measurement results, and simultaneously performing analog-to-digital conversion on the first and second sampling signals; and
b) determining a final result, wherein the first measurement result is a main measurement result and the second measurement result is an auxiliary measurement result, and the main measurement result is configured as the final result.
