Internal resistance prediction method for a storage battery involves measurement of ambient temperature and battery charge conditions

摘要

The internal resistance of the storage battery is divided into two portions: the electronic resistance (RMet), and the ionic resistance (RElyt). RMet is determined based on the ambient temperature and RElyt is determined based on the temperature and remaining charge of the battery. The total internal resistance is then predicted based on the two measured portions. Independent claims are included for: (1) an apparatus for measuring battery and environmental conditions; (2) a computer program product.
