Systems and methods for monitoring battery range for an electric marine propulsion system

An electric marine propulsion system for a marine vessel comprising:

• a power storage system comprising at least one battery;
• an electric marine drive powered by the power storage system;
• a control system configured to:
• identify at least one environmental vector describing a magnitude and a direction of at least one environmental force impacting a marine vessel;
• calculate a resultant vector based on the at least one environmental vector;
• determine a nominal range to empty based on a charge level of the power storage system and at least one present operating parameter of the electric marine propulsion system;
• determine an eccentric range based on the resultant vector and the nominal range to empty, wherein the eccentric range represents a range to empty in a plurality of directions around the marine vessel, wherein the plurality of directions include at least one of a current heading direction of the marine vessel, a heading direction 90 degrees from the current heading direction, a heading direction 180 degrees from the current heading direction, and a heading direction 270 degrees from the current heading direction;
• and
• generate an eccentric range display based on the eccentric range;
• and
• control a display device on the marine vessel to display the eccentric range display.
