Abstract: A smart-home device may include a main power rail that provides power to components of the smart-home device; an integrator coupled to the main power rail that stores energy on an energy-storage device, where the energy stored on the energy-storage device is representative of an amount an amount of power provided to the smart-home device through the main power rail during an integration cycle of the integrator; and a counter that stores a number of integration cycles performed by the integrator during a time interval, where a total amount of power provided to the smart-home device through the main power rail during the time interval is represented by: (1) the number of integration cycles performed by the integrator during the time interval; and (2) the energy stored on the energy-storage device.

Abstract: The present document describes techniques for safe battery charging during high ambient temperatures. These techniques extend device runtime during peak use periods when ambient temperature is high by increasing the possibility for battery charging during high ambient temperature conditions. In an example, a device, during high ambient temperatures, checks future ambient temperatures over a network to identify if the minimum future ambient temperature over a block of time within the next N number of days is predicted to be sufficiently low that, when combined with device-performance throttling, is estimated to reduce the temperature of the battery to below the maximum charge temperature to enable the battery to be safely charged. The device can also use the future ambient temperatures to budget current battery usage by implementing and/or adjusting device-performance throttling.

Abstract: A smart-home device may include a temperature sensor, energy-consuming subsystems, and processors programmed to receive a temperature measurement from the temperature sensor for an ambient environment surrounding the temperature sensor; receive inputs from the energy-consuming subsystems that indicate power-consuming activities of the energy-consuming subsystems; providing the inputs from the energy-consuming subsystems to a model that is trained to calculate an effect of the power-consuming activity of the energy-consuming subsystems on the temperature measurement from the temperature sensor; and calculating an estimate of the temperature of the ambient environment by compensating the temperature measurement from the temperature sensor with using the effect of the power-consuming activity of the energy-consuming subsystems.
