Embodiments described herein are directed to a charging assembly for use with a battery. The assembly includes an engine, a voltage regulator, an engine control unit, a charging controller, and a rectifier. The engine drives an alternator for producing either of a single or multi-phase AC voltage. The voltage regulator communicates with said alternator. The rectifier converts the AC voltage from the alternator to DC prior to delivery to the battery pack. The engine operates at variable speeds during charging of the battery, including an initially higher revolutions per minute corresponding to a highest rate of charge when a current charge of the battery is at or below a predetermined threshold level, with a subsequently reduced revolutions per minute as a temperature of the battery is rising and the current charge of the battery is increasing, during which the rate of charge slows as directed by the battery management system.
