1. An active energy management system for a vehicle including a rechargeable energy storage system (RESS), the active energy management system comprising:
a RESS including at least one power module, the RESS configured for installation into a vehicle;
a propulsion system configured for installation into the vehicle; and
a controller module in communication with the RESS and the propulsion system, the controller module programmed with a usable energy algorithm that when executed is configured to:
calculate a usable energy of the at least one power module based on an anode lithium surface density;
compare the usable energy calculated with a first threshold; and
provide a first notification to a user when the usable energy calculated reaches the first threshold.
