US Patent 11874328 Detecting battery changeout

A computer-based system for automatically detecting when a battery changeout occurs has an input device, a neural net trained to identify when said battery changeout occurs based on data from a battery monitor and an output device. The system reads in battery data points once per a data period. The system then formats multiple data points into a data vector for the neural net. The neural net then produces an output vector indicating when a battery changeout occurs. The output vector may show a detected changeout as a step change in a graph.
