1. A battery system, comprising:
a lithium ion battery configured to couple to an electrical system;
a battery management system configured to electrically couple to the lithium ion battery and configured to control one or more recharge parameters of the lithium ion battery, wherein the battery management system is programmed with an electrochemical model;
the electrochemical model having a determination of at least one of a lithium plating reaction kinetics at an anode of the lithium ion battery and a quantity of plated lithium at the anode of the lithium ion battery, and an indication of a relationship between the one or more recharge parameters and the lithium plating reaction kinetics, the quantity of plated lithium, or a combination thereof; and
the determination and the indication having one or more outputs for an adjustment of a plating current limit for charging operations of the lithium ion battery to prevent lithium plating at the anode.
