Abstract: A power management system having automatic calibration is disclosed. The power management system may have an alternator and an electronic control unit. The electronic control unit may be configured to determine a reference voltage based on at least one measured operating condition of the alternator. The reference voltage may correspond to an overloading threshold of the alternator. The electronic control unit may be further configured to monitor a voltage of the alternator and, when the monitored voltage is less than the reference voltage, perform a corrective action to increase a power output of the alternator.

Abstract: A controller of a machine identifies that a battery of the machine is connected to an electrical power connector component. The controller then causes one or more charging components of the battery of the machine to be enabled, then cause one or more electrical components associated with the battery of the machine to be enabled, then causes one or more cooling components of the machine to be enabled, then causes one or more propulsion components of the machine to be disabled, then causes one or more accumulator components of a hydraulic system of the machine to bleed, and then causes one or more non-accumulator components of the hydraulic system of the machine to be enabled. In this way, the controller causes the battery of the machine to enter into a charging state.
