Control units, systems, and methods for establishing reserve power limits

A system comprising:

• a first device including a battery;
• and
• a control unit including:
• a processor;
• and
• non-transitory computer-readable media configured to store computer-executable instructions configured to cause the processor to:
• determine a reserve level for a battery of a first device, the reserve level configured to provide electrical power to the device to perform one or more functions;
• filter the received usage information to include at least one location which the first device has visited more than a threshold amount;
• and
• determine the reserve level further responsive to the filtered usage information;
• enable the battery to supply power to a second device external to the first device responsive to a power level of the battery reaching the reserve level;
• and
• disable the battery from supplying the power to the second device responsive to the power level of the battery falling below the reserve level.

A method comprising:

• determining a reserve level for a battery of a first device, the reserve level configured to provide electrical power to the first device to perform one or more functions;
• determining information chosen from usage information for the first device and weather information;
• and
• determining the reserve level responsive to the information, wherein determining the reserve level includes;
• receiving information identifying a grid outage area;
• selecting a target location outside of the grid outage area, the target location being a location chosen from the at least one location, which the first device has visited more than a threshold amount, and a recharge location located outside the grid outage area;
• determining an amount of power needed to get the first device to the target location;
• and
• determining the reserve level further responsive to the determined amount of power;
• and
• enabling the battery to supply power to a second device external to the first device responsive to a power level of the battery reaching the reserve level;
• and
• disabling the battery from supplying the power to the second device responsive to the power level of the battery falling below the reserve level.
