Abstract
A method and apparatus for testing a storage battery is provided that generates a temperature at which the battery will fail to meet performance criteria. The use of a temperature-based system to rate battery performance provides a clearer understanding to those not skilled in the art of battery testing. The critical failure temperature is obtained using the battery parameters of open circuit voltage, temperature and a dynamic parameter such as conductance or resistance.
