Heated garment communication

A method of providing power to a heated garment from a battery pack, the method comprising:

• pairing, via a pack transceiver of the battery pack, the battery pack to an external device;
• receiving, via the pack transceiver, a first input from the external device;
• determining, via a pack electronic processor of the battery pack coupled to the pack transceiver, an amount of current to provide to a first heating zone of the heated garment based on the first input;
• providing, via a wired connection between the battery pack and the heated garment, the amount of current to the first heating zone of the heated garment;
• receiving, via the pack electronic processor, a signal from an output port of the battery pack;
• determining, based on the signal, a second external device has been electrically coupled to the battery pack;
• and
• providing, via the output port of the battery pack, a charging power to the second external device.

A power source for a heated garment, comprising:

• a housing;
• one or more battery cells located within the housing;
• a user interface positioned on the housing;
• an electrical interface positioned on the housing for connecting to the heated garment;
• and
• a controller located within the housing and including an electronic processor and a memory, the controller coupled to the battery cells, the user interface, and the electrical interface, the controller being configured to:
• communicate with the heated garment and a device,
• communicate with and provide power to the heated garment via a wired connection,
• wirelessly communicate with the device,
• determine that the heated garment is coupled to the power source,
• determine an amount of power within the battery cells,
• determine an amount of power being used by the heated garment,
• determine a first value by multiplying the amount of power being used by the heated garment by a set runtime,
• compare the amount of power within the battery cells to the first value,
• decrease, in response to the amount of power within the battery cells being less than the first value, a heating level in a heating zone of the heated garment
• determine that a second heated garment is coupled to the power source,
• wait a predetermined amount of time,
• determine a second amount of power within the battery cells,
• determine a second amount of power being used by the heated garment and the second heated garment,
• determine a second value by multiplying the second amount of power being used by the heated by the set runtime,
• compare the second amount of power within the battery cells to the second value, and
• decrease, in response to the second amount of power within the battery cells being less than the second value, the heating level in the heating zone of the heated garment, a second heating level in a second heating zone of the second heated garment, or both.
