Battery string monitoring system

A method comprising:

• receiving, via a processor, a plurality of N voltage signals, wherein each voltage signal in the plurality of N voltage signals represents a respective voltage across a respective battery string subset of a plurality of battery string subsets making up a battery string, the battery string comprising M batteries, where M is greater than N;
• performing, via the processor, an analysis on the plurality of N voltage signals:
• identifying, based on the analysis, one of a failing battery in the battery string and a failing battery string subset;
• and
• generating a notification for a user to inspect the one of a failing battery in the battery string and a failing battery string subset.

A battery monitoring system, comprising:

• a processor;
• a test signal generator;
• a signal response receiver;
• and
• a plurality of battery connections, wherein:
• each battery connection in the plurality of battery connections is connected to a respective subset in a battery string;
• the test signal generator generates a test signal and applies the test signal to each of the respective subsets via the plurality of battery connections;
• the signal response receiver receives a response from each of the respective subsets in response to the test signal, to yield a plurality of responses;
• and
• the processor identifies an error in the battery string based on the plurality of responses.
