Systems and methods for optimizing vehicle battery usage while operating welcome lights

A vehicle comprising:

• a sensor unit configured to detect a presence and a movement of a portable device in proximity to the vehicle;
• a plurality of exterior lights;
• a battery;
• and
• a processor configured to:
• identify one or more parameters associated with the presence and the movement of the portable device in proximity to the vehicle based on inputs obtained from the sensor unit, wherein the one or more parameters comprise a distance between the vehicle and the portable device;
• and
• control an operation of at least one exterior light, from the plurality of exterior lights, based on at least one of the one or more parameters or a state of charge (SoC) level of the battery, wherein, to control the operation of the at least one exterior light, the processor:
• detects that the SoC level is less than a predefined first SoC threshold;
• detects that the distance is less than a predefined first distance threshold;
• and
• causes the at least one exterior light to illuminate responsive to detecting that the SoC level is less than the predefined first SoC threshold and the distance is less than the predefined first distance threshold,
• wherein the processor is further configured to cause the at least one exterior light to illuminate for a predefined time duration responsive to detecting that the SoC level is less than the predefined first SoC threshold and the distance is less than the predefined first distance threshold, and wherein the predefined time duration is based on the predefined first SoC threshold.
