Machines, systems and methods for automated power management

A method for controlling a motive machine having a main machine controller (MMC) operably coupled to a power module by a CAN bus, the method comprising:

• controlling, based on a functional mode of the machine, an engine revolutions per minute (RPM) of an engine to a default engine RPM;
• receiving, from the power module, load information corresponding to a load of a sub-system operably coupled to the power module;
• and
• automatically adjusting the engine RPM based on the sub-system load information and the functional mode of the machine.

At least one machine-readable medium including instructions for a main machine controller (MMC) to operate a control system for a motive machine, the motive machine having a power module and a sub-system operably coupled to the MMC by a CAN bus, and the instructions, when executed by a processor, cause the processor to:

• control, based on a selected functional mode of the machine, an engine speed of an engine to a default engine speed;
• receive, from the power module via the CAN bus, load information corresponding to a load of the sub-system;
• and
• automatically adjust the engine speed based on the sub-system load information and the selected functional mode of the machine.

A motive machine that is selectively operable in a plurality of functional modes, the machine comprising:

• an engine;
• a main machine controller (MMC) operably coupled to the engine;
• a power module operably coupled to the MMC by a controller area network (CAN) bus;
• a sub-system operably coupled to the power module by the CAN bus, wherein the power module monitors a load of the sub-system, and using the monitored load of the sub-system, the power module communicates sub-system load information to the MMC;
• and
• a solenoid associated with the power module, wherein the solenoid protects the machine in case of a short, and wherein the output from the power module is switched on when a high side current switch of the solenoid closes, and wherein the solenoid closes after power on self-tests of the machine have been successfully completed and no shorts or errors have been identified.
