A vehicle includes a traction battery and a controller in communication with the battery and programmed to control battery charging in response to a user-selected one of a plurality of charging strategies having different charging rates based on detection of lithium plating in the battery. The charging strategies may include options for faster charging with an urgent or emergency charging strategy selectable a limited number of times to mitigate battery performance degradation associated with lithium plating. A method implemented by a vehicle controller in a vehicle having a traction battery, may include controlling, by the controller, battery charging in response to a user-selected charging strategy selected from one of a plurality of available charging strategies each having a different charging rate and displayed on a user interface in response to detection of lithium plating in the traction battery, at least one charging strategy associated with additional lithium plating if selected.
