1. A method for managing a lithium-ion cell, the method comprising:
adjusting one or more limits applied during one or both of charging and discharging of the lithium-ion cell, using an enhanced algorithm;
wherein the enhanced algorithm is configured to control the one or more limits of the lithium-ion cell to extend one or more of cycle life, cumulative capacity before end of life, and cumulative energy before end of life;
wherein the enhanced algorithm uses a state-of-health model associated with the lithium-ion cell to calculate the one or more limits;
wherein the one or more limits comprise one or more voltage limits that comprise a minimum voltage; and
wherein the adjusting comprises altering the minimum voltage using the enhanced algorithm, based on a state-of-health modeling of a tradeoff between at least two parameters or characteristics of the lithium-ion cell.
