Abstract
A user device can include a first battery configured to power the user device and a second battery configured to power the user device. The user device can further include a temperature sensor configured to monitor a temperature of the second battery and a heating element configured to heat the second battery to increase an operating efficiency of the second battery when a temperature of the user device falls below a threshold temperature value. A switch can be configured to switch on the heating element to heat the second battery when the temperature sensor determines that the second battery is below a threshold temperature value.
Claims20
A user device, comprising:
- a first battery configured to power the user device;
- a second battery configured to power the user device, the second battery being of a smaller capacity than the first battery;
- and
- a heating element configured to generate heat within the second battery to increase an operating efficiency of the second battery when a temperature of the user device falls below a threshold temperature value,
- wherein the first battery and the second battery are battery cells within a battery pack, and
- wherein the heating element directly heats the second battery instead of directly heating the first battery.
A method of powering a user device, comprising:
- powering the user device with a first battery;
- powering the user device with a second battery, the second battery being of a smaller capacity than the first battery;
- and
- heating, with a heating element, the second battery to increase an operating efficiency of the second battery when a temperature of the user device falls below a threshold temperature value,
- wherein the first battery and the second battery are battery cells within a battery pack, and
- wherein the heating element directly heats the second battery instead of directly heating the first battery.
