SYSTEM AND METHOD FOR ACTIVE ENERGY MANAGEMENT FOR AN ELECTRIC VEHICLE

A method of active energy management for a vehicle including a rechargeable energy storage system (RESS). The method includes: calculating, via a controller programmed with a usable energy algorithm, a usable energy of the at least one power module based on an anode lithium surface density; comparing, via the controller, the usable energy calculated with a first threshold; providing, via the controller, a first notification to a user when the usable energy calculated reaches a first threshold; providing, via the controller, a second notification to the user when the usable energy calculated reaches a second threshold, providing a third notification to the user when the usable energy calculated reaches a third threshold, and suggesting actions to the user based on the notifications.
