Abstract

An automated charge preparation method periodically determines critical parameters for the set of relevant operating conditions, determines whether fast charging is possible, applies fast charging when possible, otherwise applies a dynamically scaled charging rate that is optimized based upon current critical parameters (while optionally heating the individual battery cells as long as fast charging is not available) to reduce/eliminate a risk of lithium-plating.
