1. A method for generating a servicing schedule of an electrified vehicle, the method comprising:

  • collecting, via processing circuitry, a first set of multi-load data from a power control unit of a vehicle and usage data at a first servicing of the vehicle;

    computing, via the processing circuitry, a Mahalanobis Distance (MD) using the first set of multi-load data;

    defining, via the processing circuitry, a healthy state and an anomaly threshold based on the MD;

    correlating, via the processing circuitry, the first set of usage data to the anomaly threshold;

    generating, via the processing circuitry, a usage based servicing schedule for a vehicle;

    collecting, via the processing circuitry, a next set of multi-load data and usage data at a next servicing of the vehicle;

    updating, via the processing circuitry, the MD, a servicing schedule and evaluating the performance of the vehicle;

    determining, via the processing circuitry, whether the MD crosses the anomaly threshold; and

    transmitting, via a network, a servicing alert upon exceeding the anomaly threshold to the vehicle.
