Claim 18:
19. An electrified vehicle comprising:
a chassis;
a front axle coupled to the chassis;
a rear axle coupled to the chassis;
a battery pack;
an electric motor electrically coupled to the battery pack, the electric motor configured to drive at least one of the front axle or the rear axle; and
a controller configured to:
monitor a state-of-charge of the battery pack;
monitor a temperature of the battery pack;
monitor a depth-of-discharge of the battery pack during discharge events;
prevent (i) charging the battery pack above a maximum state-of-charge threshold that is less than 100% state-of-charge, (ii) prevent the depth-of-discharge from exceeding a depth-of-discharge threshold, and (iii) prevent the temperature from exceeding a temperature threshold to prevent accelerated degradation of a state-of-health of the battery pack;
adaptively reduce the maximum state-of-charge threshold as the state-of-health of the battery pack degrades; and
adaptively adjust the depth-of-discharge threshold such that the state-of-charge can be further depleted during subsequent discharge events as the battery pack degrades.
