System and method for improving a battery management and accumulator system

A system, comprising:

• a power system including a battery system structured to store energy to be used to power one or more engine subsystems of a vehicle and an energy recovery system structured to harvest energy from one or more engine subsystems of the vehicle and to provide the energy to the one or more engine subsystems;
• and
• a controller operatively and communicably coupled to the power system, the controller structured to:
• monitor an alternator current of the battery system;
• compare the monitored alternator current to a current limit of the alternator;
• receive energy data, energy storage data, and current data regarding each engine subsystem in a group of engine subsystems;
• reduce an energy output of the battery system based on the alternator current, current limit, and the received energy data, energy storage data, and current data;
• categorize each engine subsystem in the one or more engine subsystems as either a primary load or as a load having an energy storage capability;
• and
• manage the reduced energy output from the battery system to each engine subsystem based on whether the engine subsystem is categorized as either a primary load or as a load having the energy storage capability in order to:
• maintain the energy output of the battery system to each primary load engine subsystem;
• and
• reduce at least a portion of the energy output of the battery system to each engine subsystem having the energy storage capability.

An apparatus, comprising:

• a battery circuit structured to manage energy to power one or more engine subsystems of a vehicle;
• an energy circuit structured to manage harvesting energy from one or more engine subsystems of the vehicle and to provide the energy to one or more engine subsystems;
• a comparator circuit communicably coupled to the battery circuit and the energy circuit, the comparator circuit structured to:
• monitor an alternator current of the battery system;
• compare the monitored alternator current to a current limit of the alternator;
• receive energy data, energy storage data, and current data regarding each engine subsystem in a group of engine subsystems;
• reduce an energy output of the battery system based on the alternator current, current limit, and the received energy data, energy storage data, and current data;
• and
• a management circuit structured to:
• categorize each engine subsystem in the one or more engine subsystems as either a primary load or as a load having an energy storage capability;
• manage the reduced energy output from the battery system to each engine subsystem based on whether the engine subsystem is categorized as either a primary load or as a load having the energy storage capability in order to:
• maintain the energy output of the battery system to each primary load engine subsystem;
• and
• reduce at least a portion of the energy output of the battery system to each engine subsystem having the energy storage capability.
