Apparatus for predicting battery lifespan and method predicting battery lifespan

An apparatus comprising:

• a storage configured to store first battery data;
• an input interface configured to acquire second battery data from a vehicle;
• a processor configured to:
• train, using the first battery data, a battery lifespan model for predicting a lifespan of a battery of the vehicle;
• acquire, based on the second battery data, an output of the trained battery lifespan model;
• and
• predict, based on the output of the trained battery lifespan model, a lifespan value of the battery;
• and
• an output interface configured to transmit the predicted lifespan value of the battery to the vehicle,
• wherein the battery lifespan model comprises:
• a basic lifespan model associated with first battery cell data collected in a first operating environment;
• a cell lifespan model associated with second battery cell data collected in a second operating environment;
• and
• a pack lifespan model associated with an output of the cell lifespan model and battery pack data collected in the first operating environment.
