Abstract

Apparatuses, systems, devices, and methods for power management during system startup at low temperatures are disclosed. An apparatus includes a battery for an electronic device. The battery includes one or more cells. The apparatus includes a thermal insulation element configured to insulate heat that the battery. The thermal insulation element is coupled to the battery to prevent at least a portion of the heat that the battery generates from being dissipated from the battery during startup of the electronic device.

Claims (45)

1. An apparatus, comprising:

a battery for an electronic device, the battery comprising one or more cells; and

a thermal insulation element configured to insulate heat that the battery generates,

wherein the thermal insulation element is coupled to the battery to prevent at least a portion of the heat that the battery generates from being dissipated from the battery during startup of the electronic device, and

wherein the thermal insulation element comprises a material configured to insulate heat that the battery generates up to a predefined temperature and to conduct heat away from the battery in response to the heat that the battery generates exceeding the predefined temperature.

2. The apparatus of claim 1 , wherein the thermal insulation element is coupled to at least one cell of the one or more cells of the battery.

3. The apparatus of claim 1 , wherein the thermal insulation element is coupled to the battery and covers at least one surface of the battery.

4. The apparatus of claim 1 , wherein at least one cell of the one or more cells of the battery comprises a jelly roll, the insulation element wrapped around the jelly roll.

5. The apparatus of claim 1 , wherein the insulation element comprises an insulating sheet, the insulating sheet comprising a nano silica balloon insulator (“NASBIS”) sheet.

6. An apparatus comprising:

a battery for an electronic device, the battery comprising one or more cells;

an electrical heating element coupled to the battery, the electrical heating element activated during startup of the electronic device and configured to operate until a threshold temperature is satisfied, wherein the electrical heating element is embedded within a label adhered to the battery; and

a thermal insulation element configured to insulate heat that the battery generates,

wherein the thermal insulation element is coupled to the battery to prevent at least a portion of the heat that the battery generates from being dissipated from the battery during startup of the electronic device.

7. The apparatus of claim 6 , wherein the thermal insulation element comprises a material configured to insulate heat that the battery generates up to a predefined temperature and to conduct heat away from the battery in response to the heat that the battery generates exceeding the predefined temperature.

8. A system comprising:

a battery for an electronic device, the battery comprising one or more cells;

a thermal insulation element configured to insulate heat that the battery generates;

a temperature module that monitors a temperature associated with the electronic device during startup of the electronic device; and

a power module that, in response to the temperature being less than a threshold temperature, is configured to limit a discharge current of the battery to be less than a predefined discharge current threshold.

9. The system of claim 8 , wherein the predefined threshold is 0.5 C, where C is a rate at which the battery is discharged relative to its maximum capacity.

10. The system of claim 8 , wherein the thermal insulation element comprises a material configured to insulate heat that the battery generates up to a predefined temperature and to conduct heat away from the battery in response to the heat that the battery generates exceeding the predefined temperature.

11. The system of claim 8 , wherein the power module disables a fan within the electronic device during startup of the electronic device, the fan operable to dissipate heat from the electronic device.

12. A system comprising:

a battery for an electronic device, the battery comprising one or more cells;

a thermal insulation element configured to insulate heat that the battery generates;

a temperature module that monitors a temperature associated with the electronic device during startup of the electronic device; and

a power module that, in response to the temperature being less than a threshold temperature, disables a fan within the electronic device during startup of the electronic device, the fan operable to dissipate heat from the electronic device.

13. The system of claim 12 , wherein the thermal insulation element comprises a material configured to insulate heat that the battery generates up to a predefined temperature and to conduct heat away from the battery in response to the heat that the battery generates exceeding the predefined temperature.

14. A system comprising:

a battery for an electronic device, the battery comprising one or more cells;

a supercapacitor;

a thermal insulation element configured to insulate heat that the battery generates;

a temperature module that monitors a temperature associated with the electronic device during startup of the electronic device; and

a power module that, in response to the temperature being less than a threshold temperature, is configured to trigger discharge of the supercapacitor during startup of the electronic device until the temperature reaches a threshold temperature.

15. The system of claim 14 , further comprising a heater embedded in the battery, the power module configured to activate the heater during startup of the electronic device.

16. The system of claim 14 , wherein the thermal insulation element comprises a material configured to insulate heat that the battery generates up to a predefined temperature and to conduct heat away from the battery in response to the heat that the battery generates exceeding the predefined temperature.

17. The system of claim 14 , wherein the power module disables a fan within the electronic device during startup of the electronic device, the fan operable to dissipate heat from the electronic device.

18. A system comprising:

a battery for an electronic device, the battery comprising one or more cells;

a thermal insulation element configured to insulate heat that the battery generates;

a temperature module that monitors a temperature associated with the electronic device during startup of the electronic device; and

a power module that, in response to the temperature being less than a threshold temperature, is configured to dynamically adjust a cut-off voltage threshold for the electronic device during startup of the electronic device, the cut-off voltage threshold set in firmware for the electronic device.

19. The system of claim 18 , wherein the thermal insulation element comprises a material configured to insulate heat that the battery generates up to a predefined temperature and to conduct heat away from the battery in response to the heat that the battery generates exceeding the predefined temperature.
