Method and system for electrical energy storage swapping

A computer-implemented method, comprising:

• simulating, by a processor device of a computer system, using electrical multi-battery models, the performance of a propulsion electrical energy storage system of a vehicle based on logged vehicle routes of the vehicle, the electrical energy storage system comprising multiple electrical energy storage packs,
• predicting, by the processor device, a lifetime of the electrical energy storage system based on the simulated performance of the propulsion electrical energy storage system and extrapolating forward assuming a worst-case aging rate;
• when the predicted lifetime exceeds a predetermined lifetime, indicating, by the processor device, that an electrical energy storage pack downgrade replacement is required, and
• reducing, by the processor device, a state of charge window of the electrical energy storage system at a rate such that a predetermined minimum state of charge window is not reached before a planned electrical energy storage pack downgrade replacement.
