Abstract: A fire fighting vehicle includes a powertrain including an engine, a battery pack, and an electromechanical transmission; a power divider; and a controller. The power divider is positioned between the engine, the pump, and the electromechanical transmission. The controller is configured to monitor a state-of-charge of the battery pack and operate the engine, the power divider, and the electromechanical transmission such that the state-of- charge is maintained above a minimum state-of-charge threshold that is sufficient to facilitate (i) accelerating the 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. An aggregate of the acceleration time and the period of time is at least three minutes.
