Determination of fuse life in a fuse system

A vehicle comprising:

• at least one battery component configured to store energy, the vehicle being at least partially an electric vehicle;
• a fuse element operatively connected to the at least one battery component and configured to receive a current;
• a controller operatively connected to the fuse element and having a processor and tangible, non-transitory memory on which is recorded instructions for executing a method for determining a remaining fuse life of the fuse element;
• wherein the controller is deactivated at an initial time from a first wake cycle and then activated after a key-off time duration (to) from the initial time, execution of the instructions by the processor causing the controller to:
• determine at least one temperature (T) of the fuse element, the remaining fuse life being based in part on the at least one temperature (T);
• obtain a last-known temperature delta of the fuse element, the last-known temperature delta being a last-known temperature difference from the first wake cycle between the fuse element and an ambient temperature (TA);
• determine a correction factor based in part on the key-off time duration (t0) and a predefined constant (τ);
• obtain a corrected temperature delta (ΔT) as a product of the correction factor and the last-known temperature delta, the at least one temperature (T) being based in part on the corrected temperature delta (ΔT);
• and
• control operation of the vehicle based on a magnitude of the remaining fuse life, including limiting the current received by the fuse element if the remaining fuse life is below a second threshold.
