The invention comprises automatically tuning a power management system (1000) adapted for use with a vehicle or marine electrical power system (100) powered by an internal combustion engine (105) and an alternator (110) driven by the internal combustion engine (105). A control module (220) of the power management system (1000) operates to determine maximum current limits able to be drawn from the alternator (110) by the control module for a predetermined alternator voltage setpoint at discrete engine operating speeds including an idle speed and at least one operating speed above idle speed, and generating a control strategy for controlling the current drawn from the alternator (105) at a prevailing engine speed using the determined maximum current limits and an error signal based upon the difference between the alternator voltage and the predetermined alternator voltage setpoint.
A method of automatically tuning a power management system adapted for use with a vehicle or marine electrical power system powered by an internal combustion engine and an alternator driven by the internal combustion engine, the power management system comprising a power control system comprising a DC-DC converter for converting power from the electrical power system, and a control module controlling the DC-DC converter, the method comprising steps performed by the control module of:
A control module for a power management system adapted for use with a vehicle or marine electrical power system powered by an internal combustion engine and an alternator driven by the internal combustion engine, the power management system comprising a power control system comprising a DC-DC converter for converting power from the electrical power system, wherein the control module is configured to self-calibrate by performing steps of determining maximal current limits drawn from the alternator at respective discrete engine operating speeds by the control module for a predetermined voltage setpoint, the discrete engine operating speeds including an idle speed and at least one operating speed above idle speed;
A power management system adapted for use with a vehicle or marine electrical power system powered by an internal combustion engine and an alternator driven by the internal combustion engine, the power management system comprising a power control system comprising a DC-DC converter for converting power from the electrical power system, a control module for controlling the DC-DC converter, wherein the control module is configured to self-calibrate the power management system following installation to the electrical power system by performing steps of determining maximal current loads drawn from the alternator at selected number of engine operating speeds and for a predetermined voltage setpoint, and generating a control strategy based upon controlling the current drawn from the alternator using an error signal based upon the difference between the alternator voltage and the predetermined voltage setpoint.
