Apis: Architecture for Federated Power Management

Abstract

Internet of Things (IoT) devices have been limited in application by constraints posed by batteries. Batteries add size, weight, and upkeep costs, and limit the lifetime of devices preferred to be small, lightweight, and long-lasting. We present Apis, a software and hardware toolkit for federated power management in energy harvesting applications. By replacing batteries with rapid charging storage capacitors, circuitry to control federated energy storage, and software support to make this architecture accessible to developers, embedded devices can potentially run indefinitely with limited maintenance. We present the Apis hardware for controlling federated energy storage, supporting software, and experiments performed to validate the Apis model.
