MICRO-ENERGY COLLECTION-BASED POWER MANAGEMENT METHOD AND DEVICE, AND MICRO-ENERGY SUPPLY DEVICE

摘要

A micro-energy collection-based power management method and device, and a micro-energy supply device. The SOC-based method comprises: selecting a collection mode according to a current power source electric quantity and a current collected electric quantity for micro-energy collection (S101); setting a communication threshold and a load threshold (S102); regularly determining whether the current power source electric quantity is greater than the communication threshold or not according to a timestamp, and communicating with a server when the current power source electric quantity is greater than the communication threshold (S103); and regularly determining whether the current power source electric quantity is greater than the load threshold or not, and supplying power to the load when the current power source electric quantity is greater than the load threshold (S104). A power management system is established on SOC on the basis of the existing IC, and the power consumption is further reduced by setting power priority to be suitable for power supply limit for micro-energy collection, achieving power management of micro-amps-level power consumption, increasing the application scope of energy collection, breaking environmental restrictions for energy collection, and expands the application field of clean energy.
