Battery diagnostic system for estimating the remaining useful life (RUL) of a battery

摘要

PROBLEM TO BE SOLVED: To provide a battery diagnostic system for reusing a used battery for a second life use. A battery diagnostic system 102 for predicting the remaining useful life of a battery 114 and diagnosing the battery from a predetermined set of features indicating the battery cycle of the test battery and the capacity of the test battery. From memory 104, which stores a neural network trained to estimate life (RUN), and a charging system 110, which charges and discharges the test battery to provide measurement of battery cycle and capacity of the test battery. It includes a processor 108 that extracts a predetermined set of features and sends the extracted feature set to a neural network, and an output interface 112 that outputs the estimated RUL of the test battery.
