In-situ battery monitoring system

The present disclosure provides a system, method, and apparatus for battery monitoring. In one or more embodiments, the disclosed method involves injecting at least one test signal into a battery, and receiving at least one response signal from the battery. In one or more embodiments, the response signal(s) comprises at least one reflected signal. The method further involves comparing, with at least one processor, the response signal(s) with at least one baseline signal to produce at least one comparison signal. Also, the method involves detecting, with at least one processor, at least one anomaly within the battery by using the comparison signal(s). Further, the method involves determining, with at least one processor, a location at least one anomaly within the battery by using the comparison signal(s).
