Abstract
Systems, apparatuses, and methods are described for managing temperature of a rechargeable battery between multiple available states of heating. Different thresholds may be used for turning on, and turning off, one or more heating elements associated with the rechargeable battery, and/or for otherwise changing states of the one or more heating elements.
Claims20
A method comprising:
- receiving information indicating a temperature associated with a rechargeable battery;
- receiving information indicating a voltage level associated with the rechargeable battery;
- adjusting a heating element, associated with the rechargeable battery, between three levels of heating based on the temperature, the voltage level, and a threshold for acceptable battery operation of a video doorbell, wherein the three levels of heating comprise:
- an off state;
- a high heating state;
- and
- a low heating state.
4 more elements
A method comprising:
- receiving, by a computing device, a video image from an image sensor;
- performing object recognition to recognize an object in the video image;
- and
- adjusting, based on the recognized object in the video image and based on a threshold associated with operation of a battery-powered video doorbell, a battery heating level of the battery-powered video doorbell.
1 more element
A method comprising:
- receiving temperature and voltage information associated with a video doorbell battery;
- increasing a heating state of a battery heater based on:
- a first voltage level of the battery;
- and
- a first temperature of the battery falling below a first threshold associated with operation of the video doorbell;
- and
- decreasing the heating state of the battery heater based on:
- a second voltage level of the battery;
- and
- a second temperature of the battery rising above a second threshold associated with operation of the video doorbell, wherein the second threshold is different from the first threshold.
