More Information
Summary:An electrical energy storage system includes a battery container, one or more temperature sensors, and a controller. The battery container includes one or more batteries configured to store and discharge electrical energy. The temperature sensors are configured to measure one or more temperatures associated with the battery container. The controller is configured to estimate a rate of heat generation by the one or more batteries based on the measured temperatures, monitor an electric current provided to the one or more batteries, and estimate a resistance of the one or more batteries based on the estimated rate of heat generation and the electric current.
