Abstract

This specification describes technologies related to adaptive power management for Internet-of-Things (IoT) doorbell systems. These technologies incorporate supercapacitors as a secondary power source for IoT doorbell systems. Supercapacitors offer significant advantages, including long cycle life, reduced carbon footprint over the lifecycle, and superior performance under harsh environmental conditions. These technologies also include an adaptive input power management system that improves system compatibility by enabling the IoT doorbell to operate with low-power transformers, such as those found in older homes. Additionally, an adaptive chime management system is included to improve the operational reliability of the supercapacitor-powered doorbell system.

Description

Adaptive Power Management for Video Recording Doorbell Systems Many existing Internet of Things (IoT) doorbell systems rely primarily on batteries, such as lithium-ion batteries (LIBs), for power. However, these batteries face several challenges, including environmental impact, limited lifespan, and safety issues. For example, the production and disposal of LIBs generate carbon emissions, raising concerns among environmentally conscious consumers and requiring regulatory compliance for carbon reduction. Harsh outdoor environments accelerate LIB degradation, resulting in a shorter-than-expected lifespan and the need for frequent replacements, causing inconvenience to consumers and increasing electronic waste. In some cases, LIBs can pose safety risks due to potential thermal runaway phenomena. This specification describes technologies related to adaptive power management for video recording doorbell systems. These technologies incorporate supercapacitors as a secondary power source for IoT doorbell systems. Supercapacitors offer significant advantages, including long cycle life, reduced carbon footprint over the lifecycle, and superior performance under harsh environmental conditions. These technologies also include an adaptive input power management system that improves system compatibility by enabling the IoT doorbell to operate with low-power transformers, such as those found in homes. Additionally, an adaptive chime management system is included to improve the reliability of operation of the supercapacitor-powered doorbell system. In one example, a video recording doorbell is disclosed. The video recording doorbell comprises a housing, one or more supercapacitors, a charger, an adaptive input manager module, and a microcontroller unit (MCU). One or more supercapacitors are placed within the housing and are configured to provide secondary (auxiliary) input power for the operation of the video recording doorbell when primary (main) input power is temporarily switched to provide power to a doorbell chime electrically connected to the video recording doorbell. The charger is configured to charge one or more supercapacitors. The adaptive input manager module is configured to detect the presence of primary input power and to determine the input voltage of the primary input power. The MCU is configured to set an initial charging current for charging one or more supercapacitors, enable the charger to charge one or more supercapacitors using the initial charging current, and adjust the initial charging current to a new charging current based on the input voltage and a voltage threshold. In another example, a video recording doorbell system is disclosed. The video recording doorbell system comprises a video recording doorbell, a doorbell chime, a transformer, a chime connector, an adaptive input manager module, and a microcontroller. The video recording doorbell includes one or more supercapacitors configured to provide secondary input power to the video recording doorbell.
