摘要
Abstract
The small isotope thermoelectric battery is a promising new type of battery,but it suffers from defects such as high internal resistance and weak output power.Conventional buck-boost cir-cuits fail to realize efficient energy harvesting and optimal utilization of isotopic materials.This study develops an energy harvesting system based on the BQ25570 micropower management IC for small-scale isotope thermoelectric batteries,incorporating maximum power point tracking functionality to achieve high-efficiency collection of output energy from isotope batteries,with a peak energy conver-sion efficiency reaching 87.3%.The system integrates energy harvesting,main control,and wireless charging modules,significantly expanding the application scope of isotope batteries.关键词
