Abstract

In one aspect, non-invasive methods are described in which combinations of certain battery parameter values are used to identify whether metal plating (e.g., lithium plating) has occurred during charging of a battery. In response to the detection of metal plating and/or conditions associated with metal plating, one or more characteristics of a charge process may be adjusted or adapted to maintain battery parameter values within a specified range. In some cases, after detection of metal plating, a battery charge process may be adjusted or adapted to remove metal plating from a battery's anode by a discharge pulse.
