1. An electrified fire fighting vehicle comprising:
a powertrain including:
a battery pack;
an electric motor; and
an engine; and
a controller configured to:
monitor a state-of-charge of the battery pack;
operate the electric motor using stored energy in the battery pack to provide a performance condition including (i) accelerating the electrified fire fighting vehicle to a driving speed of at least 50 miles-per-hour in an acceleration time and (ii) maintaining or exceeding the driving speed for a period of time, wherein the acceleration time is 30 second or less, and wherein an aggregate of the acceleration time and the period of time is at least 3 minutes; and
start and operate the engine in response to a start condition to facilitate reserving sufficient stored energy in the battery pack such that the state-of-charge is maintained above a minimum state-of-charge threshold that is sufficient to facilitate the performance condition, wherein the start condition includes at least one of (i) the minimum state-of-charge threshold being reached or (ii) receiving a start command from an operator.
