Abstract
A marine propulsion system includes an engine effectuating rotation of an output shaft, a battery, an alternator having a rotor driven into rotation by the output shaft and that is configured to generate a charge output to the battery, a battery state of charge sensor configured to measure a battery charge value of the battery, and a control system. This control system is configured to receive a demand value and/or a temperature, receive the battery charge value from the battery state of charge sensor; and control the alternator to adjust the charge output based on at least one of the battery charge value and the demand value and/or temperature.
Claims22
A marine propulsion system comprising:
- an engine effectuating rotation of an output shaft;
- a battery;
- an alternator having a rotor driven into rotation by the output shaft and that is configured to generate a charge output to the battery;
- a battery state of charge sensor configured to output a battery charge value of the battery;
- a control system configured to:
- receive a demand value and/or a temperature, wherein the temperature includes at least one of an under-cowl air temperature, an oil temperature, or a coolant temperature;
- receive the battery charge value from the battery state of charge sensor;
- and
- control the alternator to adjust the charge output based on at least one of the battery charge value and the demand value and/or the temperature.
A marine propulsion system comprising:
- an engine effectuating rotation of an output shaft;
- a battery;
- an alternator having a rotor driven into rotation by the output shaft and that is configured to generate a charge output to the battery;
- a control module configured to:
- receive a demand value;
- determine an adjusted alternator setpoint based on the demand value;
- and
- communicate the adjusted alternator setpoint to an alternator controller for the alternator such that the alternator generates the charge output to the battery based on the adjusted alternator setpoint.
A method of controlling an alternator configured to generate a charge output to a battery in a marine propulsion system, the method comprising:
- receiving a battery charge value of a battery charged by the alternator;
- receiving a demand value;
- determining an adjusted charge output based on the demand value and the battery charge value;
- and
- controlling the alternator based on the adjusted charge output to reduce at least one of the charge output to the battery and an engine output power utilized by the alternator.
