Apparatus and method for communication and negotiation of charge rate between electronic smoking device and charger

A system comprising:

• an electronic smoking device comprising
• a battery,
• an eCig memory storing a first set of computer-readable instructions, and
• control electronics configured to execute the first set of computer-readable instructions to place the electronic smoking device in a first plurality of modes;
• and
• a charger comprising
• a charger memory storing a second set of computer-readable instructions, and
• a charger processor configured to execute the second set of computer-readable instructions to place the charger in a second plurality of modes;
• wherein the first plurality of modes comprises an operation mode, a low power sleep mode, and a light sleep mode, where the light sleep mode uses less power than an operation mode and the low power sleep mode uses less power than the light sleep mode, and
• wherein each of the first plurality of modes has at least one complementary mode in the second plurality of modes, and wherein the control electronics and the charger processor are configured to communicate and to negotiate a charge rate for charging the battery when the electronic smoking device is electrically connected to the charger.

A method for charging an electronic smoking device comprising:

• connecting the electronic smoking device to a charger, wherein control electronics of the electronic smoking device are in a first eCig mode and wherein a charger processor of the charger is in a first charger mode,
• switching the control electronics from the first eCig mode to a second eCig mode,
• switching the charger processor from the first charger mode to a second charger mode,
• negotiating, between the control electronics and the charger processor, while the electronic smoking device is in the second eCig mode, and while a charge rate for charging a battery of the electronic smoking device, the charger is in the second charger mode, and
• charging the battery at the negotiated charge rate,
• wherein the first eCig mode of the electronic smoking device is selected from the group consisting of a low power sleep mode, a communication mode, an operation mode, and a light sleep mode, and wherein the second eCig mode is a charge mode.
